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!
Yes. A galaxy contains many stars.
A "Galaxy"
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.
No. A typical galaxy has billions of stars.
Yes, much bigger. There are many stars in our galaxy, thousands of millions of them. Everything you see in the night sky is in our galaxy, including the Moon, so the galaxy is much bigger.
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.
No. Of course not. The universe is big enough to hold earth and all the other planets in the Milky Way Galaxy and all other galaxies and the sun and the moon and the stars. There is no way that the universe could be smaller that Earth. =)
