If not for the wonders of radio astronomy, these ideas would remain just ideas but slowly science is catching up with theory. But the brilliance of mathematicians and genius minds like Hawking and Einstein continue to stretch our concepts of space. Now we have the string theory that could revolutionize everything we know about space, time and how the universe relates to itself.
Light, obviously, is the physical phenomenon that empowers our ability to use our visual confirmation system, e.g. our eyes to appreciate something, in this case the stars. So when we look up at the heavens, we can see the light emitting from a star or reflecting from a planet or moon. In many cases, if we see a far away star, we are actually seeing it hundreds or thousands of years ago because that is how long it takes for that light to cross the universe and be visible in our sky.
Comets - Visitors From Beyond The one thing we love the most in the world of astronomy is a good mystery. And if there was ever a mysterious and yet very powerful force of nature that we witness in the night skies, it is the coming of the mighty comet. We should never confuse comets with asteroids. Asteroids are small space rocks that come from an asteroid belt between Mars and Jupiter.
Maybe it s all the science fiction stories about visiting the moon, Mars and other planets. But we love to think about those planets that make up what we call the solar system. that do what our planet does but do it very differently indeed. The planets of our solar system have taken on personalities and mythical appeal in our literature and arts.
Early explorers, particularly by sea, relied exclusively on the night sky to help them find their way to their destination. In fact, when Columbus sailed the ocean blue in 1492 and discovered America, he could not have done it without astronomy and the help of navigation of the cosmos, much of which is made possible because of the important constellations.
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 source of meteoroids because of the nature of those long tails. A large amount of dust, ice and other space debris gets caught up in a comet s tail as it moves toward the sun.
