"The Night Sky"," This is the first time we could well see the cosmos and in the night sky. Most of us have no idea scattered from the large picture of the lights in a clear night sky when there are no city lights to interfere with vision. But I bet I can as a child I saw the sky seems clearly remember all the constellations incredible feet, and comets that move and a statement of points of light too much to tell the story. That is great. The fact that almost surely, almost all points in the sky a star or other celestial body that is much larger than the earth itself, not twice or ten times, but by factors of hundreds and thousands of people, an idea is blowing in spirit children. * Our sun is part of a large galaxy called the Milky Way, which contains a hundred billion stars or more like it. * The milk was one of tens of billions of galaxies each with billions of stars in them. * If you could go through the Milky Way for 100,000 years. You would have to drive five hundred million 500,000,0000 miles per year These little fun facts have a lively discussion on the origin of the universe and the possibility of space travel, or whether there is life on other planets. This debate can be fun, exciting and full of questions. And if you were there the first moment when they saw the night sky, you can experience your own great moment when you were a child. . WHAT'S UP
"Watching the Night Sky"," But if you live out in the country, away from all the city lights, you can see a sky full of stars! But stars aren't the only things up there. School science teaches us that there are eight planets in the solar system. After Mars comes the asteroid belt; a ring of massive rocks floating in space. The other planets are incredibly far away. You will need a lot of space! The sun needs to be about the size of a soccer ball, Earth would be a peppercorn, and Neptune would be a peanut. Then take 10 steps away. Then take 9 more steps to reach Venus, and 7 paces after that. To reach the spot where Neptune should be, you would need to take 751 more steps! That's really far. Mercury and Venus can be seen in the early evening; they look like really bright stars. Saturn often appears very large because of its rings, and with a simple telescope, you can even spot some of its moons. It's not a UFO, it's just one of the thousands of manmade things we put into space. Be sure to wave at it - someone may be watching! Other times, you might see bright streaks of light across the sky. Some even hit the ground! If a meteor reaches the ground, it becomes a meteorite. Learning about constellations is very popular in school science. Some of the most popular stories come from Greek myths; according to the myths, there is a giant lion in the sky, there are gods and goddessses, a winged horse, and even a scorpion. Comets are massive balls of frozen ice, rock, and gases. It's hard to tell when a new comet may cross the night sky, so be sure you look up from time to time.

"How to Explore the Night Sky Without a Telescope"," For example five of the planets are often readily visible with the naked eye. To maximize what you can see in the night sky there are a few things you should do as preparation. And this includes the moon. Its brightness will wash out many of the dimmest and most dramatic objects in the sky. Make sure you dress appropriately for the weather and bring extra layers of clothing if you are observing during cold months. Bring along any items to help your comfort like a lawn chair or a reclining lawn chair so you can look up without craning your neck. This means get away from street lights, city lights, house lights, or any other type of light source. If this is not possible then try to find the darkest spot you can. This will decrease your ability to see the dimmer objects. It takes your eyes up to a half an hour to fully adjust to the darkness outside. Equipment and stuff to bring along Get some star maps, planet charts, and reference materials and bring them right outside with you. But it will be dark outside so you won't be able to read them! And if you turn on some kind of a light or flashlight your night vision will be ruined. Cover your flashlight with some type of red cellophane or tape so it only gives off a dim red glow. You can buy flashlights with red covers online, at astronomy and optical shops, or even at military surplus stores. And the best viewing will be when it is only a think crescent. With a full or near full moon the light hits the surface of the moon directly and casts no shadows. You can see this galaxy as a band of diffuse light that stretches across the sky. Every star and constellation map will show you where the milky way stretches across the sky. Each constellation represents an object, animal, or historic figure; and learning the story behind them can also be a lot of fun. They form the background that everything moves within and they give you a frame of reference for finding these objects. The Planets - The planets move around in the sky quite a bit and sometimes they are too close to the position of the sun which means they are not visible at night but five of the planets, when in the right position are easily visible with the naked eye. And often times these planets are the brightest objects in the sky. One rule of thumb for figuring out whether something is a star or a planet is whether or not it twinkles. So if you locate an object that you believe is a planet you can watch it for several minutes to see if it twinkles like other stars. Colorful Stars - Stars are not all white. Stars come in a wide variety of brilliant colors and some of the more notable ones are the bright red Betelgeuse in Orion, the bright light-blue Rigel in Orion, the yellowish-white Altair in Aquila, and the bright red Antares in Scorpio. It can also be quite easy because some of the brightest stars in the sky are also very colorful from white to blue and red. These are the Andromeda galaxy and the Hercules Nebula. Once you start getting familiar with the constellations you should look for these two objects. Periodic and occasional Objects The night sky is filled with a lot of objects that come and go in different patterns. This is when the Earth passes through clouds of space debris. Some meteor showers can give as many as 120 falling stars every hour. But occasionally a comet will become very bright and be easily visible with the naked eye. It is a extraordinarily rich environment with objects of all kinds. All you need is dark skies, a few charts, and a little bit of time. WHAT'S UP
