The name of an incident does not necessarily reflect the exact location of that incident. Galaxies are so big and spread out at the ends that even though galaxies bump into each other, the planets and solar systems often don’t get close to colliding.Each incident is given a name to assist with managing multiple incidents. They tell me that your warkshop's in Lunnon - an ' a'm sure a never saw that the. But even if it happened tomorrow, you might not notice. , you know, who has now represented this district of. It won’t happen for about five billion years. Our Milky Way galaxy will someday bump into Andromeda, our closest galactic neighbor. Sometimes galaxies get too close and smash into each other. The light that we see from each of these galaxies comes from the stars inside it. They have irregular shapes and look like blobs. And there are also galaxies that aren’t spirals or ovals. Other galaxies are smooth and oval shaped. They have curved arms that make it look like a pinwheel. Some galaxies are spiral-shaped like ours. The universe is a very big place! Credit: NASA, ESA, CSA, and STScI This image covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground. This is a picture taken by the NASA’s James Webb Space Telescope showing thousands of galaxies. Some scientists think there could be as many as one hundred billion galaxies in the universe. There are so many, we can’t even count them all yet! The Hubble Space Telescope looked at a small patch of space for 12 days and found 10,000 galaxies, of all sizes, shapes, and colors. There are many galaxies besides ours, though. The Milky Way galaxy fills the night sky in this photo. If it’s really dark, far away from lights from cities and houses, you can even see the dusty bands of the Milky Way stretch across the sky. When you look up at stars in the night sky, you’re seeing other stars in the Milky Way. Our galaxy, the Milky Way, also has a supermassive black hole in the middle.
But where is our solar system? It’s a small part of the Milky Way Galaxy.Ī galaxy is a huge collection of gas, dust, and billions of stars and their solar systems. We live on a planet called Earth that is part of our solar system. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity.
