Galaxies - Paperback

by Rebecca Woodbury M. Ed (Author)

A galaxy is a huge group of stars, planets, gas, dust, comets, asteroids, and other objects in space. Our Sun and Earth are part of the Milky Way Galaxy, which is so huge that we cannot travel outside it to see what it looks like. But by studying other galaxies and how stars are arranged in the Milky Way, astronomers can develop an idea of what it looks like. To do this, astronomers use telescopes, which are instruments used to study galaxies and other objects in space. Scientists think the Milky Way Galaxy is shaped like a pinwheel with a bulge of stars in the center and arms made of stars that reach out in a spiral. Because of this shape The Milky Way is called a spiral galaxy, and we can see many spiral galaxies in the universe. Another type of galaxy we can see is the elliptical galaxy made of tightly packed stars with no arms, and there are also irregular galaxies that can be any shape. There are trillions of beautiful galaxies in space.
