Shooting Stars

If you are a businesslike astronomy fanatic like a lot of us are, you can probably remember that one event in greenness that started you along this exciting hobby. It might have been that first time you looked through a telescope. But owing to many of us, it was that inaugural time we saw a rain of fire from the sky that we eventually came to know as a meteoroid shower.

At the time when you see the first only, it’s easy to remember the movie “war of the worlds” or some other fantastic image of aliens entering our atmosphere in droves to returns over the planet. But with some guidance and explanation of what was going on, we eventually learned that these showers were not at outright threatening or any kind of invasion. For the most part meteoroid showers are harmless, part of nature and very fun to watch.

So what are these strange lights in the sky? Are they aliens invading from Mars? Are the comets coming to start the next ice age? Or perhaps asteroids burning up as they enter the earths atmosphere. The answer to the above questions is no to the first and “yes and no” to the other two.

A meteoroid is actually a small piece of space rubble, usually dust or small rocks that come from either a comet or the break up of an asteroid in space and that eventually plummets healthful the earth. We say “toward the earth” as the lights you scope are the friction of the atmosphere burning up those small space tidbits and creating a glittery show for all of us as they do so. A particularly exciting moment to witness is when a meteoroid breaks up or explodes on entry. A meteoroid that explodes is called bolides.

There are some interesting details about the life of a meteoroid that cause the viewing of shooting stars even more fun. To be seen, a meteoroid only needs to weigh as minute as a millionth of a gram. But the thing that makes them so spectacular to see is the tremendous speeds they reach as they enter the impression. Before burning up, a meteoroid will reach between 11 and 74 kilometers per second which is 100 times faster than a speeding bullet.

We tend to think of t seeing a shooting star as a freak event and we associate it with superstition ( hence, wish on a lucky tin god ). But there are actually thousands of them every year so it really isn’t that rare to see one. In fact, scientists tell us that over 200, 000 tons of space matter enters the atmosphere each year and burns up on entry.

Comets are a big genesis of meteoroids because of the nature of those long tails. A large amount of dust, ice and other space debris gets curious up in a comet’s tail as it moves toward the sun. Then due to the comet moves away from the sun in its orbit, tons of this matter is thrown off concern space to radiate. As the Earth moves in its routine orbit around the sun, it often crosses through clouds of this bygone matter which becomes one of those “meteor showers” that are so popular in that viewing.

These showers of shooting stars are pretty easy for astronomers to predict so you can get into position to gawk the sense at just the right duration of night and appear as looking at the right area of the night sky. Usually the astronomy magazine or site will give you a general time and location to be ready to look when the meteoroids start to fall.

Now keep in mind, this is a phenomenon of nature, so it may not observe the time table exactly. Also diversion that know onions is a notation system for where the meteoroid shower will occur based on what constellation is its backdrop. The section of the sky to heart on for the show is called the “radiant” because that is where the inward meteoroids begin to oxidation or radiate. The radiant is named for the constellation factual is nearest too. So if the meteor shower is going to occur in the constellation of Leo, then its radiant will be called Leonid. This will help you decipher the oblique of asteroid showers in the publications.
