Celestial Bodies - PowerPoint PPT Presentation

Celestial Bodies

Celestial bodies by: adrian g, erin n, and kelsey m introduction do scientists know all about our galaxy, the milky way no. there is much that waits to be discovered. – powerpoint ppt presentation.

• By Adrian G, Erin N, and Kelsey M
• Do scientists know all about our galaxy, the Milky Way? No. There is much that waits to be discovered. This PowerPoint show focuses on celestial bodies. Celestial bodies are constellations, comets, meteors, asteroids, galaxies, and basically everything in space.
• Famous Asteroids
• The Asteroid Belt
• Between Mars and Jupiter (or the divider between the near and far planets)
• Maybe over one million asteroids over 0.5 miles across
• A planet may have once existed there, the asteroids may be leftover debris of the planet
• Meteors are made up of rock and dust. Meteors are smaller than asteroids. They are called meteorites when they hit planets. The biggest meteor ever found was Hoba West and weighed 66 Tons. There are small meteors called micrometeoroids. Meteor showers are seen as streaks of light. Some people call them shooting stars. A lot of times, these shooting stars come in showers over several nights.
• Our galaxy is called the Milky Way, a spiral galaxy. There are four main types of galaxies, Spiral, Elliptical, Irregular, and Barred-Spiral. Our Solar System is found in the outer reaches of the Milky Way, and is a tiny speck compared to the vast Milky Way. Millions of Solar Systems, or groups of stars and planets are in the Milky Way. Galaxies are so big that even the small ones take billions of light years to cross. Galaxies are formed by clouds of spinning gasses, and some of those clouds still spin.
• Local Galaxies
• Large Magellanic Cloud
• Small Magellanic Cloud
• Canis Major
• Canis Minor
• Taurus Vela
• Piscis Austrinus
• Has details on Details page
• Canes Venatici
• Coma Berenices
• Capricornus
• Corona Australis
• Corona Borealis
• Microscopium
• Sagittarius
• Telescopium
• Fall/Winter
• Mid-November to late December
• Long line of stars named after mythological Greek river
• One star, Epsilon Eridai, 10.8 light years away
• Another star, Achernar, 85 light years away
• Mid-September to mid-November
• Resembles Perseus, ancient Greek hero
• Many open star clusters
• One star, Algol, has an eclipse for almost 3 days, one star passes in front of it and Algol fades to nearly ½ of its brightness
• A meteor shower occurs between July 25 and August 20 in Perseus
• Spring/Summer
• Found in Spring
• Looks like a herdsmen
• Found in Summer
• Greeks thought it looked like it held a snake
• Stars change by moving, because the Big Dipper wasnt the shape of a dipper at first, but many years later it changed and looked like a big dipper.
• The universe is still expanding by the Big Bang. The big bang was the asteroid that might have killed the dinosaurs.
• There are many galaxies like M33, M32, Wolf- Lundmark, and Etc.
• Stars move approximately ten miles each second. Our galaxy is a spiral galaxy.
• An asteroid called Ida has a moon.
• Comets, meteors and asteroids are different because we often see meteors, but not comets or asteroids.
• Some comets are so far away that you cant see them move.
• In olden times, comets were called a bad omen.

White House directs NASA to create unified time standard for the Moon and other celestial bodies

NASA will establish a unified standard of time for the Moon and other celestial bodies, as the White House aims to set international norms in space. 

The directive comes amid a growing lunar race among nations and private companies.

The head of the White House Office of Science and Technology Policy (OSTP) instructed the space agency to work with other parts of the US government to devise a plan by the end of 2026,  in a memo seen by Reuters.

The setting would be called Coordinated Lunar Time (LTC). 

The differing gravitational force on the Moon and on other celestial bodies change how time unfolds relative to how it is perceived on Earth. 

The LTC would provide a time-keeping benchmark for lunar spacecraft and satellites that require extreme precision for their missions, NASA's space communications and navigation chief Kevin Coggins says. 

"The same clock that we have on Earth would move at a different rate on the Moon," Mr Coggins said. 

"Think of the atomic clocks at the US Naval Observatory [in Washington]. They're the heartbeat of the nation, synchronising everything," Mr Coggins said.

"You're going to want a heartbeat on the Moon."

Under its Artemis program, NASA is aiming to send astronaut missions to the Moon in the coming years and establish a scientific lunar base that could help set the stage for future missions to Mars.

Dozens of companies, spacecraft and countries are involved in the effort.

An OSTP official said without a unified lunar time standard it would be challenging to ensure the data that transfers between spacecraft are secure and that communications between Earth, lunar satellites, bases and astronauts are synchronised.

Discrepancies in time also could lead to errors in mapping and locating positions on or orbiting the Moon, the official said.

On Earth, most clocks and time zones are based on Coordinated Universal Time, or UTC.

This internationally recognised standard relies on a vast global network of atomic clocks placed in different locations around the world.

They measure changes in the state of atoms and generate an average that ultimately makes up a precise time.

Deployment of atomic clocks on the lunar surface may be needed, according to the OSTP official.

While the US is the only country to have put astronauts on the Moon, others have lunar ambitions.

Countries have their eyes on potential mineral resources on the Moon, and lunar bases could help support future crewed missions to Mars and elsewhere.

In 2023, China said it aims to put its first astronauts on the Moon by 2030.

In January, Japan became the fifth country to put a spacecraft on the Moon.

India last year became the first country to land a spacecraft near the unexplored lunar south pole, and it has announced plans to send an astronaut to the Moon by 2040.

"US leadership in defining a suitable standard — one that achieves the accuracy and resilience required for operating in the challenging lunar environment — will benefit all space faring nations," the OSTP memo stated.

Defining how to implement Coordinated Lunar Time will require international agreements, the memo added.

Solar Eclipse

Can't make it to the total eclipse 5 fun ways to bring wonder and awe into your life.

On Monday, April 8, millions of people across the U.S. will be able to view a total solar eclipse — an experience that eclipse chaser and science writer David Baron says will change your life.

"You will see a sun you've never seen before," he told Life Kit in an interview . "It's like you've left the solar system and are looking back from some other world."

But ... what if you can't make it to this awe-inducing, otherworldly, once-in-a-blue-moon solar event?

Don't worry — there are other ways to bring wonder and enchantment into your everyday life. Here are 5 tips from Life Kit's experts.

NPR will also be sharing highlights here from across the NPR Network throughout the day Monday if you're unable to get out and see it in real time.

To capture the bizarre, make sense of your dreams

Want to capture the surreality of the eclipse you can't make? Try interpreting your dreams . Deirdre Barrett, a dream researcher at Harvard, explains how. Say your intention aloud at bedtime. "Just tell yourself as you're falling asleep that you want to remember your dreams," she says.

The moment you wake up, write down your dream and "take a moment to notice what you were dreaming and think about whether it has any potential relevance in your waking life," says Barrett. Pay attention to the symbols and images. Then ask yourself what those visuals mean to you. To find out how to use your dreams to solve problems , listen to our episode.

To behold supernatural beauty, open your eyes to novelty

Yes, the total eclipse will be the most brilliant event in the heavens on Monday, but that doesn't mean you can't find beauty in the world around you . Jenny Odell, author of How to Do Nothing , explained how to do this in a 2020 interview with Life Kit.

Be attentive to change, she says. Walk through your neighborhood and "try to pay attention to things that are flowering. This is a good time to be doing that because it's spring," she says. "Maybe over the course of weeks or months, continue to pay attention to those plants and track their flowering processes." Or you might focus on the different kinds of insects flying and buzzing about, or the sounds around you.

This exercise can help reopen your eyes to enchantment and novelty in your everyday life. For more exercises on how to pay attention , listen to our episode.

To alter your perception, look at a work of art

Just like a viewing an eclipse, connecting with a piece of art that really moves you can change your life . But how do you do that?

Even though it may not be what the artist intended, let yourself draw personal connections to the art, says art historian Susie Hodge. A color, a pattern or flower in a painting, for example, "might trigger something in your childhood or the deep recesses of your memory."

These free associations will help elicit an emotional reaction when you look at a work. Let your mind wander and follow your train of thought wherever it leads you. And a deep connection "will happen," says Hodge. Read the full story to get tips on what to look for when standing in front of a work of art .

To conjure powerful emotions, connect your heart to a poet's

Witnessing something as supernatural as an eclipse can conjure powerful emotions that you may not be able to describe — but perhaps a poet can. See if you can connect feelings to words and move your heartstrings by reading poetry .

To do that, Harryette Mullen, a poet and professor at the University of California, Los Angeles, says to let go of trying to unlock the meaning of a poem as the poet intended and interpret it in your own way. Take a look at this poem, " The Song of Wandering Aengus " by William Butler Yeats. Ask yourself: What overall impression do you get? What ideas float around in your mind? What do you feel? Just look around in your own brain as you read the poem and take in what's there.

"Those kinds of overall impressions, I think most of us are left with something," says Mullen. Whatever that "something" is — trust it. Find out how to "visualize" a poem in this story.

To transform your body and mind through nature, try 'forest-bathing'

Yes, viewing a total solar eclipse can be a transformational experience — but so can other elements of nature. Like spending time in the forest, what the Japanese call shinrin-yoku . "It is simply being in nature, connecting with it through our sense of sight, hearing, taste, smell and touch," says Qing Li, a researcher on this topic and a professor at Nippon Medical School in Tokyo.

Gary Evans, director of the Forest Bathing Institute in the U.K. , explains how to connect your body and mind to nature. Find a place in a forest or park where you are surrounded by trees. Settle in a spot that feels beautiful and resonant to you.

Now sit down, says Evans, and breathe deeply. "Inhale for a count of two and exhale for a count of four. Then keep that going. When the exhale is slower than the inhale, it sends a physiological message to your body that says: 'I'm safe. I can relax. It's OK.' "

You may be surprised by what you discover, says Evans. "Depending on what's happening in your emotional world, quite often when we look at nature or the forest, it sends something back to us to help us make sense of what's going on in our life." Learn more about the science of forest bathing and how it affects mental and physical health.

White   House Office of Science and Technology Policy Releases Celestial Time Standardization Policy

Knowledge of time in distant space operating regimes is fundamental to the scientific discovery, economic development, and international collaboration that form the basis of U.S. leadership in space. Today, the White House Office of Science and Technology Policy (OSTP) is releasing the first-ever U.S. government policy memorandum on time standards at and around celestial bodies other than Earth, building upon the Biden-Harris Administration’s National Cislunar Science and Technology Strategy .

“As NASA, private companies, and space agencies around the world launch missions to the Moon, Mars, and beyond, it’s important that we establish celestial time standards for safety and accuracy,” said OSTP Deputy Director for National Security Steve Welby . “Time passes differently in different parts of space—for example, time appears to pass more slowly where gravity is stronger, like near celestial bodies—and as a result the length of a second on Earth is different to an observer under different gravitational conditions, such as on the Moon. A consistent definition of time among operators in space is critical to successful space situational awareness capabilities, navigation, and communications, all of which are foundational to enable interoperability across the U.S. government and with international partners.”

A unified time standard—Coordinated Lunar Time (LTC)—will act as the established standard to enable cislunar operations and can be tied to Coordinated Universal Time (UTC), the primary time standard globally used to regulate clocks and time on Earth. This policy directs NASA to work with the Departments of Commerce, Defense, State, and Transportation to deliver a strategy for the implementation of LTC no later than December 31, 2026. NASA will also coordinate with other federal agencies as appropriate and international partners through existing international forums, including Artemis Accords partner nations.

Divers discover 2 more bodies in Italian hydro powerplant explosion. Death toll hits 5

Firefighters in Italy say that divers have discovered two more bodies of workers who died in an explosion that collapsed and flooded several levels of an underground hydroelectric plant earlier this week, bringing to five the number of confirmed dead

MILAN -- Divers in northern Italy discovered the bodies of two more workers who died in an explosion that collapsed and flooded several levels of an underground hydroelectric plant, bringing to five the number of confirmed dead, officials said Thursday.

The explosion Tuesday at the Enel Green Power plant, in the northern Bologna province, occurred at depth of some 40 meters (130 feet) below water level. The search for two other missing workers was continuing.

Divers who have been working to recover victims likened the scene to an underwater earthquake -struck building.

The blast at the Enel Green Power’s Bargi plant happened during work to increase the plant's efficiency, the company said in a statement. A fire broke out when a turbine exploded on the eighth floor below the surface, flooding the floor below. The cause was still unknown.

Move over, eclipse. A rare, double brood of lustful cicadas are about to take over the skies

More than a trillion cicadas to emerge from the ground and blanket 17 states this spring.

Social Sharing

Floyd Shockley is planning a road trip to witness a rare natural event that will darken skies across much of the United States — a convergence not of celestial bodies, but of two massive broods of flying, screaming, lustful insects.

This spring, two broods of cicadas, totalling more than a trillion, will emerge from the earth in search of mates and blanket huge swaths of the U.S. for months.

"A solar eclipse is absolutely a cool event, right? But it's actually in a much smaller area than the cicadas are going to cover," Shockley, an entomologist with the Smithsonian National Museum of Natural History in Washington, D.C., told As It Happens host Nil Köksal.

"And we have solar eclipses actually more frequently on Earth than these dual emergences. So this is an even rarer event than the solar eclipse."

Tasty snacks for wildlife

There are seven species of cicadas in North America that are periodical, meaning they spend more than 99 per cent of their lives dwelling underground as nymphs before emerging all at once to moult, mate, lay eggs and then die.

This spring, two multi-species groups of cicadas, known as broods, will come out for their end-of-life bacchanalias. 

Places where people like to go to hang out ... are going to be filthy with cicadas. - Floyd Shockley

Brood XIII, which emerges every 17 years, and Brood XIX, which comes out every 13 years, will overlap for the first time in 221 years.

All seven periodical species will be visible this year, which won't happen again until 2037.

"It's going to be really great if you're an entomologist," Shockley said. "And it's going to be even better for wildlife. This is a really abundant food source, so birds and mammals and reptiles are going to be going crazy enjoying all these cicadas."

Cicada nymphs only leave their underground home when the soil warms to about 17.7 C, he said. "That is the cue for them to start digging their way up to the surface."

Once they emerge, the nymphs crawl up hard surfaces, like tree trunks or telephone poles, then moult into winged adults.

Some have already come out in Virginia, Shockley said, and the first big wave in the coming weeks is expected in Louisiana, Mississippi, Alabama and Georgia. 

In May and June, Shockley says, they'll start coming out in the midwestern U.S., and then finally in the northern part of the country. 

They live about four to six weeks after they moult, so the last ones will be lucky to make it to July. All together, the lovelorn insects will cover 17 states.

Shockley plans to be in Illinois for late May and early June, when both broods will be active in different parts of the state simultaneously.

"So literally just a few miles away from one another  ... you'll be able to hear all seven species singing their individual song in just a short distance," he said.

"It's a really exciting opportunity, and it's one that many of us won't ever get to see again."

University of Connecticut evolutionary biologist John Cooley agrees. 

"There's nowhere else in the world where it's possible to see anything at all like this," he said. 

What to expect

Cicadas are about 2.5 to five centimetres long, with sturdy bodies, bulging compound eyes and membranous wings.

If you're in the coverage zone, Shockley says you'll likely find them near the ground in the early morning. As it warms up during the afternoon, they'll "start flying around looking for a really great perch to start singing from."

That "singing" is actually a mating call the males make using special organs on their abdomens. 

"It's a male chorus all going off all at once with one purpose — to woo the ladies," Shockley said.

If interested, females will respond with wing flicks, which also make a sound.

Underground, the nymphs feed on plant juices from the roots of deciduous trees and shrubs. So anywhere there are a lot of trees, Shockley says, there will be a lot of cicadas.

"Places where people like to go to hang out in the spring and summertime, like parks and things, are going to be filthy with cicadas for about two months. They're going to be out there screaming and flying and doing their thing," Shockley said.

In some places, he says, the skies will be downright thick with them.

"When we had Brood X here in the Washington, D.C., area [in 2021], you know, when you were driving along the Beltway, they were pinging off of your windshield like you were driving through a hailstorm."

'They're very gentle'

Shockley says he understands that not everyone is as excited as he is about swarms of screaming insects.

"It can definitely be scary, especially if you have a natural aversion or are afraid of bugs," he said. 

Still, he urges people to remember they pose no threat.

"They're very gentle. They don't bite. They don't harm plants," he said. "I think they definitely get a bad rap."

Whatever you think of them, Cooley says cicadas deserve our respect.

"I always counsel people to treat them with the respect and awe due to such remarkable creatures," Cooley said.

"The species have a long history — millions of years. And that history is much longer and deeper than the history of the landscapes and forests in which they live — on the order of tens of thousands of years. So the cicadas are a natural part of the ecosystem."

We look at the night sky and are overwhelmed at the mass of stars and other bodies in our sky. During the daylight we feel comfortable because we can recognize and have understanding of the general movement of the SUN and moon. Many years ago with no city lights, the stars seemed brighter at night and stars were studied and visualized as familiar figures. These figures, pictures, are known as constellations, with given names and shapes, people gave names to the constellation groups and to the individual stars. Constellations are the way that many learn about the sky and help as a memory aid to the stars that form the figures, the constellations did organize this endless wonder, our sky. As scientist looked longer at our sky they categorized stars and found that they could predict their movement, making an almanac for the past, now and the future. This makes the location in the sky of a star possible when the constellation is partly covered, or when only one star is visible. Finding one single star is not difficult. If two friends are looking at the sky, and one was an astronomer, it would be easy for the astronomer to locate a star and point to it so that you could see it and know the name. But! If you were not together, instead linked to a telephone, the astronomer would have to explain the star location by a system, of direction and height above the horizon. CELESTIAL ASTRONOMER. Intro 1. ASTRONOMER.

V, North 000 d “Your Horizon Your Sky” <{1}North 35degrees = your Latitude. • THE HORIZON System. (See figure “Your Horizon ”. Numbers are places to look.) > • The Astronomer could describe the NORTH STAR as “{1.} Look NORTH and (your LATITUDE) 35 degrees above your horizon.” He could say “look eastward or {2.}) 055 at 40 degrees high” for another {3.} Look westward at 260 and 20 degrees high” for another star. With little practice you can section off and locate areas of the sky for easy star identity. Without the Astronomer to give direction and height you need the Celestial ASTRONOMER to take his place. • After dark, while out side, you can find the North star or use a compass to find a close to North direction. After some practice you can section off your sky in to bearings and altitude. Let North be at 12 o'clock, the hour hand of the clock hours gives 30 degree sections of bearing around horizon. • The altitude at the horizon, looking straight ahead is zero. Ninety degrees is overhead, You can use the hour hand for altitude, over head =12 o'clock down to your horizon at 3 o'clock and zero altitude, this will help sectioning your sky. ^{2} 055@ 40 < W 270 <E 090 <You ^{3} 260@20 Intro 2.

24 Understanding PARTS of the CELESTRIAL ASTRONOMER 1.BASE DISK. The purpose of the BASE DISK is to interact and supply information to other disk. Description: (opaque and circular.) The BASE DISK is approximately nine inches in diameter. The BASE DISK is of a bird eye view of the NORTH hemisphere with the WEST to the left and the EAST hemisphere to the right. A pin in the center (that all other disk can rotate on) contains the earth as a molecule that projects into far outer space useful information on its outer rims in terms of: 1. DEGREES labeled every ten from zero to 360 that are used for LONGITUDE. (LONG.) The same DEGREES are used for GREENWICH HOUR ANGLE (GHA) and SIDEREAL HOURS ANGLE (SHA.) (Used for Celestial Bodies.) 2. MONTHS of the YEAR. With the days of the month, each day equals one degree. 3. GREENWICH MEAN TIME (GMT) and Time ZONES. With 12:00 military time at Greenwich England Zero Longitude and each of 24 time zones of 15 degrees for the complete 24 hours day. The Base Disk will enable interaction reading of between degrees, Time of the year, ( month and day) and time of the day, ( hour and minuets.) PBD 3

{1} 35N {1} 35N Horizon Disk. {3} YOU PARTS. Celestial ASTRONOMER HORIZON DISK. The purpose is to project your position and horizon (sky) in to outer space and to grid your sky in to bearings and altitude. (This will enable you to read the Horizon system and go out side to locate stars.) Description: Opaque. There are nine Horizon disks that range from 05 North just above the equator to 85 North (N) near the pole, they are back to back, making 5 disk. Each of the nine Horizon’s has a different shape due to latitude (LAT) distortion (from a round earth projected to a flat paper tangent to the named latitude (LAT). 5N is oblong and 85N is a circle. {1} 35N Detail: Each of the nine Horizon Disk are labeled with the Lat. that it was projected from. You use the LAT. nearest to your known LAT. position. You put the disk on the BASE DISK pin and rotate the LONGITUDE (LONG) {2} pointer to your (LONG). The + {3}in the white center is your position. Looking N towards the pin you will see your horizon 90 degrees from your position bearing 000. The bearings will increase to the right 90 to 180 to 270 back to 000. Over your position (+) is ninety degrees altitude from any horizon/ bearing, with ten degree increments down to your Horizon of zero. Any celestial body that enters this grid can be read off, bearing and altitude. Each of the disks are read in the same way. <{2}Long pointer {2} LONG Pointer HD 5. Horizon System Disk

PARTS CELESTRIAL ASTRONOMER STAR DISK Transparent. The purpose: to lock named stars and other celestial bodies together as to read/ interact with the BASE DISK and HORIZON DISK. Details: Transparent and circular. The Star Disk has one pointer. Called ARIES.{1} ARIES controls all stars and bodies on the disk, as ARIES pointer rotates around the Months, days Hours, minutes and degrees on the BASE DISK so will all bodies rotate. The EARTH EQUATOR and the CELESTRIAL EQUATOR are projected into outer space midway from the center to the rim. All bodies are either NORTH declination (DEC) (ABOVE) or SOUTH DEC. (BELOW) the CELESTIAL EQUATOR. ( Declination is the same as Latitude.) The Base Disk will supply the correct placement of Aries on the Base Disk so that the Horizon Disk grid can be used to read the Bearing & Altitude of bodies on the star disk. SD 6 {1} Aries

STARS Star finding. Unique, How it works The ASTRONOMER uses the Base Disk outer rim, and other Disk to solve difficult problems. For Star Identity, the Base Disk, Horizon Disk and the Star Disk are used. The Eternal Almanac for Aries (Months & Days) on the rim simplifies and eliminates the need for an Almanac and the computation of figures and formulas on paper. The Eternal Almanac’s on the BD, Aries months are equal in degrees to the start of the same month in the almanac. Each of the degrees, days on the BD, after the month is equal to each day reading in the almanac at 00 Greenwich Mean Time for that day. . By reading the GMT on the ASTRONOMER Base Disk for the Month and day 11 June as 05:20 you are selecting 00 minutes GMT of the day 11 June for Aries as if you read that same month and day out of the Almanac in degrees. Since you are working in GMT, you can conveniently add your desired observation time directly, 10:00 GMT of desired observation time to the 00 minutes for 11 June time 05:20 to place the Aries pointer on the GMT of 15:20 on the BD. This easy procedure will give you the same answer as if you worked the difficult paper formula using the Almanac. The GMT 15:20 is now equal to GMT of 10:00 on 11 June. Another advantage of the GMT on the rim is you can work forward in observation time to see how the bodies moves in relation to your position on earth, as time increases. Also, you can quickly catch any mistake, the complete problem is visible 0n the ASTRONOMER. S 10. Note (Later) See GMT& LMT to convert to Local Time.

V CELESTRAL^ EQUATOR @ zero & 90 V N&S Declination Pole Center Pin CELESTIAL ASTRONOMER PARTS. TRANSFER ARM. The purpose of the TRANSFER ARM is to transfer planets and other celestial bodies on the STAR DISK. It can also be used to solve Great Circle problems. Description: transparent and circular. The TRANSFER ARM is a disk split in half with a pointer at each rim. The CELESTIAL EQUATOR circles the pole (pin.) The split pointer line intersects the equator at zero declination/and projected earths zero latitude. The top pointer line runs from the celestial Equator to 90 degrees north at the pole, to 90 degrees south at the south pole. The lower pointer, runs from the equator to 30 degrees north and south and is cut with a slot wide enough to insert a marker through to the STAR DISK to add Planets or stars. T11.

ASTRONOMER Instructions. GREENWITCH MEAN TIME and LOCAL MEAN TIME... The Demonstrator Base Disk can enable you to convert Greenwich Mean Time (GMT) to Local mean time LMT by using Zone Time and Zone Description. Greenwich Mean Time (GMT) is the time at Greenwich England, and zero longitude, GMT is used mainly for Sun rise/set and positioning the First point of Aries, the reference for stars and other celestial bodies. Local mean time is the time at your central longitude (the closes TZ.) where you live and the time on your clock. Zone Time is a multiple of every 15 degrees of longitude (15, 30, 45…) and labeled with 24 hour military time. Zone Description is the difference between Greenwich England (12:00) and where you live your closest labeled Zone Time. The importance of each is: GMT keeps track of the Celestial bodies. LMT is your clock that schedules your day and night and places the sun high in your sky at 12:00 noon. Your Zone Time is your longitude and is the closes one of the 24 time numbers on the base Disk. Zone Description describes the difference between12:00 at GMT and your longitude Zone Time.

See design below. {Numbers are places to go to} The outer rim of the Demonstrator Base Disk is labeled in GMT only and can be read from Zero degrees of Longitude 12:00 (at Greenwich) to the left (WEST HEMISPHERE) from 12:00, clock wise to +00/24. To the right (EAST HEMISPHERE) from 12:00 counter clockwise to -00/24. Example. {Numbers are places to go on the diagram below} Question: You are at longitude 72 W hemisphere. Your longitude {1} 72W, reading is Zone Time 17:00 on the Base Disk outer rim; your LMT clock on your shelf reads 10: 03. You want to convert to GMT? Answer. The difference between Greenwich 12:00 and your longitude (72W) 17:00 is plus +5, so Zone Description is +5.You must add + 5 to your clock, 10:03 plus +5 =15:03 GMT. Question: You read off the Demonstrator outer rim the GMT of Sunset 23:20 {2}. Your longitude is 100 W {3} what would your LMT on your clock read? Answer. The difference Greenwich 12:00 and your longitude (100 W) 19:00 is plus +7, so Zone Description is +7. To go from GMT to LMT you must always reverse the sign and subtract 7. The GMT off the BD reads 23:20 – 7 hours LMT is16:20. The Eastern Hemisphere works in the same way, the difference is that the counter clock wise longitude would have a zone Time of 72 E is -5 and 100 E would be a -7. 1. 72W +5 GMT LMT 23.
