LIFE OF A COMET:

"MOVING AROUND THE UNIVERSE, COMETS ARE ETERNAL PIECES OF ROCK AND ICE FLYING IS SPACE. BUT A PLANET CAN GET IN THEIR WAY AND..."

What is the universe? An immense space whereplanets, galaxies, asteroids and comets move around. Stard systems are part of galaxies. Each galaxy moves abut in the cosmos.

There are also comets going around planet and galaxies. They usuallyfollow the same orbit so they visit the same places over and over again. They are pieces of rock and ice moing very fast. Some are small and some are large.

On March 23rd, 1993, three astronomers,Eugene Shoemaker, his wife Carolyn and David Levy observed some small points in the their 45-centimeter telescope at Palomar Observatory in San Diego, California (Unites States). At first, they did notknow what these small points were.

The comet was called "Shoemaker-Levy9". The comet was as big as a mountain. Astronomers calculated that it was ten kilometers wide! But that was not all. Itorbited Jupiter, the biggest planet in the solar system. And was on a collision course with it!.

yes, the " shoemaker-levy 9 " could crash into jupiter. astronomers and scientists were very excited.this was the first time that they could see this incredible event. also, the comet divided into 21 fragments so they could observe and study a multiple collision.

the comet and its fragments crashedinto jupiter between 6th and 22nd july 1994. the, people asked the question "can this happen to heart?" and the answer was "yes, it can"

scientists say that meteors fell to earth millions of yearsago. they also believe that comets and meteors killed dinosaurs. the impact of one of these rocks againts the surface of the planet is stronger than an atomic bomb and can produce a naturalcatastrophe.
