None that we know of. The Milky Way is a bit larger than the average galaxy, with somewhere between 500 billion to a trillion stars (it's difficult to know, because there are an unknown number of small and invisibly dim red or brown dwarf stars). We don't believe it possible that any single star to be much larger than about 150 solar masses.
No. Our own galaxy contains several hundred billion stars (each of which might be a solar system), the observable Universe contains hundreds of billions of galaxies, and it seems that the entire Universe is much, much bigger than the observable Universe.
Of course, there's more than one life form in this universe
The Universe is the largest body in the...well, the Universe. It never stops expanding. The Universe is full of billions of galaxies, which range in shape and size. However, none are even close to being compared in size to the Universe.
A galaxy contains billions of stars. A universe contains billions of galaxies.
well the galaxy is something with stars in and the universe is a living environment i guess hope that helps!
trillions If our galaxy with 2*1011 (two hundred billion) stars is an average size galaxy. and there are as many galaxies in the Universe as there are stars in our galaxy, then there are possibly 4*1022 stars in the Universe. But that is just a guess. There are most certainly more than 1018 stars.
Yes. A galaxy contains many stars.
biggest to smallest : universe, galaxy, star/solar system, planet, moon. The Universe is everything that exists and a galaxy is a cluster of billions of stars and then planets rotate around stars and moons rotate around planets.
No. A typical galaxy has billions of stars.
Our own galaxy has between 100 and 400 billion stars; there are hundreds of billions of similar galaxies in the OBSERVABLE Universe, and it is believed that the entire Universe is much, much bigger than the observable Universe (how much bigger, is not known). It seems that at least a large percentage of those stars have planets, which means they can be called "solar systems".
Typically irregular galaxies have the oldest stars
The visible universe. I'm a bit of a space buff and to my knowledge there aren't any celestial structures that are larger than a galaxy cluster. The only one I've come upon is the visible universe itself. I could be wrong about that but then again, I could be right. That tends to be how celestial questions like that one go. Hope this helps. Answer 2: Galaxy clusters are clusters of galaxies and therefore larger than individual galaxies. Superclusters are clusters of galaxy clusters and so are larger then galaxy clusters. Filaments are collections of superclusters and are the largest known structures in the universe.
