International Astronomy Day 2024 is on Sunday, April 28, 2024: Astronomy?

Sunday, April 28, 2024 is International Astronomy Day 2024. FedEx® International‎ FedEx Offers Reliable International Shipping Options Around the Globe.

Astronomy enables us to determine a brief history from the world with this own eyes. The heavens that twinkle while you watch out on the dark, obvious evening might not exist at this time. They been around at whatever reason for history they released that light, that has taken countless many years to achieve Earth.Celebrate this wonderful task on International Astronomy Day by taking part inside a little stargazing. Take a look at the local planetarium or library for activities, or just look for a quiet, dark place to appear out to the sparkling canvas that lies above our heads. Use books or websites to recognize the gamers within the Universe’s spectacular, historic light show.Telescopes let us see even more than is seen towards the human eye alone. On International Astronomy Day, many organizations provide the public using telescopes to see sights from the World that they’ve never witnessed before.

1)Since antiquity, people have noticed that oceans exhibit a much greater tidal range around the time of the full and new Moon. This is when the Moon and Sun are either together in the sky or are on opposite sides of the heavens. Higher tides occur during these Moon phases because the Sun also exerts a gravitational pull on our oceans, although it is only 46 percent as strong as the Moon's. When the gravitational effects of the Sun and the Moon combine, we get spring tides, which have nothing to do with the season of spring. The term refers to the action of the seas springing out and then springing back. These are times of high high tides and low low tides. A week later, during either of the two quarter Moon phases, when the Sun and Moon are at right angles to each other and their tidal influences partially cancel each other out, neap tides occur, and the tidal range is minimal. In fact, because the oceans take a bit of time to catch up to the geometry of the Moon, spring and neap tides usually occur about a day after the respective lunar cycles.

3)Tide-generating forces (TGF) are a result of the gravitational attraction between the earth, the sun, and the moon and the centrifugal force due to the relative motions of the moon around the earth, and the earth around the sun. While these forces exactly balance on average, the local mismatch at the earth's surface creates a horizontal force directed towards the surface points closest and farthest from the moon (the "lunar" TGF) and the sun (the "solar" TGF).

The crust of the earth is slightly elastic, so that it is deformed by the TGFs, creating lunar and solar tidal budges (high land) at the points closest and furthest from the moon and sun respectively. To an observer fixed on the earth's surface, these tidal budges move from east to west around the earth as it rotates each day, thus causing two luner and two solar high earth tides about each day. The period of the solar tide is exactly 12.00 hours, while the period of the lunar tide is slightly longer, 12.42 hours, due to the moon's revolution around the earth every 27 days. These tides are called the "semidiurnal" tides since they have periods of roughly 1/2 day. The inclination of the earth's spin axis to the plane of the moon's revolution about the earth and the earth's revolution about the sun creates in addition weaker "diurnal" tides with periods of roughly 1 day. The amplitude of the semidiurnal lunar high earth tide is about 1 m at the equator, about twice that of the solar tide. We do not feel these earth tides due to their very large horizontal scales (many 1000's km).

The fluid ocean also experiences the TGFs. Unlike the simple tidal budges created in the earth's crust, ocean tides have complex spatial patterns due to the complicated shapes and topographies of the different ocean basins. In general, however, ocean tides at any spot consist of a mixture of semidiurnal and diurnal tides. The world's largest semidiurnal tides exist in the Bay of Fundy (maximum high tide ~12-15 m), where the Bay of Fundy/Gulf of Maine acts as a coupled hydrodynamic system which is forced near its own resonant frequency by the semidiurnal tide in the western North Atlantic Ocean. Similar very high tides are found in other coastal areas (e.g., the Amazon and the Patagonia shelves) where the regional topography creates a near-resonant response to the adjacent deep ocean tide.

7)An International gathering of world leaders in science met in Geneva to discuss their latest findings. Each nation took a turn sharing its latest developments. The leader of one nation stood before the group and declared that they had devised a spacecraft which would allow their astronauts to fly directly to the sun. He was met with boisterous laughter from the audience, to which he boldly replied, "I know what you're thinking, but we have a plan. We're going to fly the ship at night!"

Just about everybody knows that you can't fly directly to the sun, for several reasons, not the least of which is that you can't even land there because there is no there to land on. The sun is a star, which is an enormous ball of burning gases. If you remember from your science lessons in school about the three states of matter (solid, liquid, gas) you remember that gases are not

solids. In order to land and stand on any celestial body, it would need to be solid because we are solid. Oh yeah, for us to fly anywhere near the sun we would have to build a spacecraft that could withstand over 1,000,000 degrees Kelvin AND keep the people inside protected from not only the extreme heat, but the intense light and solar radiation. Human beings were built to withstand the intensity of the sun from the distance of earth, not any closer. Even at this distance, too much exposure to the sun can be dangerous. Besides, we don't really need to fly to the sun to study it, we can make observations from afar (it's much safer).

The Source of the Sun's Tremendous Energy

You would probably think of the sun as very old, as it is estimated that the "birth" of the sun happened 4.5 billion years ago. Things that grow old usually die, but 4.5 billion years is young for our sun. It is estimated that there is enough fuel in the interior of the sun to keep that lamp burning for about another five billion years, growing twice as bright as it is now. The source of the sun's fuel is hydrogen and helium gases. Through a special chemical reaction, called nuclear fusion, the hydrogen gas is "burned" releasing an enormous amount of energy in the form of light and heat.

Two isotopes of the element Hydrogen (tritium and deuterium) collide with each other under extreme heat in the interior of the sun. The two atoms smash into each other so hard that several things happen

9)Starting with the planet closest to the sun and moving further away: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.

10)Mercury is the smallest planet in our Solar system as Pluto is no more considered as a planet and Jupiter is the largest in our Solar system.

11)The basic difference between a star and a planet is that a star emits light produced in its interior by nuclear 'burning', whereas a planet only shines by reflected light.

There seem to be an enormous number of stars that are visible to the naked-eye at a really dark site but, in fact, the eye can only see about two thousand stars in the sky at one time. We can see the unresolved light of many thousands more when we look at the Milky Way, and the light of the Andromeda galaxy, which can be seen by the eye, comes from thousands of millions of stars.

The Sun is our own special star yet, as stars go, it is a very average star. There are stars far brighter, fainter, hotter and cooler than the Sun. Basically, however, all the stars we can see in the sky are objects similar to the Sun.

The Sun (and any other star) is a great ball of gas held together by its own gravity. The force of gravity is continually trying to compress the Sun towards its centre. If there were not some other force counteracting gravity, the Sun would collapse. Outward pressure is produced by the radiation from nuclear energy generation in the Sun's interior.

14)The Sun’s gravitational pull holds the solar system together. The planets, asteroids, comets, and dust that make up our solar system are strongly attracted to the Sun’s huge mass. This gravitational attraction keeps these bodies in orbit around the Sun. The Sun also influences the solar system with its diffuse outer atmosphere, which expands outward in all directions. This expanding atmosphere fills the solar system with a constant flow of tiny, fast, electrically charged particles. This flow is called the solar wind. The region through which the solar wind blows is called the heliosphere. The heliosphere extends outward from the Sun to about 150 times the distance between Earth and the Sun. Interstellar winds may give the heliosphere an egg shape. The solar wind spreads out as it leaves the Sun. The point at which the solar wind is so diffuse that it stops having an effect on its surroundings is called the heliopause. The heliopause marks the outer edge of the solar system.

15)Gravity is a force of attraction only between bodies that have mass. The word 'gravity' comes from the Latin word "gravitas", meaning 'weight'. The force of gravity that one body exerts on another can be expressed as:

16)The Sun's mass acts through gravity to keep each of the planets in an orbit around it. These orbits are elliptical and the time each planet takes to go around the Sun depends on the distance of the planet from the Sun according to the law discovered by Kepler in the 17th century.

The orbits of the planets about the Sun are all close to the same plane. This is thought to be due to the way in which they were all formed from a disk of residual matter around the Sun following the collapse of the original gas cloud.

17)i dont know

18) polar orbit is an orbit where the satellite travels in a North to South direction instead of the common West to East orbit.

Because the earth spins in an Easterly direction, a polar orbit will eventually cover every possible combination of latitude and longitude.

This makes polar orbits very useful for satellites which monitor the earth, such as weather satellites and g

How was the International Astronomy year?

I liked it, I participated. I showed the sun to people on the first days. I went to my club's observing site, and helped do repairs. I got my telescopes out and showed stars, moon, and planets to neighbors.

4th annual International Sidewalk Astronomy Night.?

Well, ..., The Raleigh Astronomy club is actually conducting a Messier Marathon on March 20th. Although, this is primarily a club event it is open to the public. We also conduct public observing sessions on the 1st Friday of every month (weather permitting) in-front of the Museum of Natural Science in downtown Raleigh, NC. A Public Observing Session at Lake Jordan on the 2nd Friday of every month, and a public Astronomy lecture on the 4th Friday of every Month. Additionally, we conduct astro-imaging seminars, telescope tune-up (Training Clinics), and host a yearly Astronomy Day celebration at the Museum as well. See our website below for further information. All of these events are free and open to the public. You do not have to be a member of our club to attend or participate in these events.

However, Club members can also participate in a telescope loaner program where we loan out a telescope for 3-6 months so new members can try before they buy.

Frankly, if you want to engage the public, you need to go where they public is and that means into light polluted areas of town where people are out and about. Malls, Shopping Centers, Movie theaters, and the like are good places to setup. Make sure you let the owners know what you're planning to do in advance.

Believe it or not we take the light polluted areas on as a challenge to see what objects we can show the public despite the street lights and other light polluting nuisances in the area. It also gives us a chance to educate the public on how light pollution is ruining our night skies, affecting animal life, and affecting our health as humans.

Some of the objects you can view in a light polluted area on March 20th are follows: Venus, Saturn, Mars, Moon, Pleiades (The Moon will be occultating some of the stars in Pleiades), and the Orion Nebula. That's should be enough to keep the public awed.
