Detailed explanation-1: -The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them! NASA’s telescopes allow us to study galaxies beyond our own in exquisite detail, and to explore the most distant reaches of the observable universe.
Detailed explanation-2: -The Milky Way galaxy is just one of the billions of galaxies in the universe. The universe is a vast expanse of space that contains all of everything in existence. The universe contains all of the galaxies, stars, and planets. The exact size of the universe is unknown.
Detailed explanation-3: -Our galaxy probably contains 100 to 400 billion stars, and is about 100, 000 light-years across. That sounds huge, and it is, at least until we start comparing it to other galaxies. Our neighboring Andromeda galaxy, for example, is some 220, 000 light-years wide.
