There are over 100 billion galaxies (with 100 billion+ stars (each containing 9 planets and 170+ moons)) in each one; as well as asteroid belts and nebulae) in the Big O universe (in reality; Paradigm City is a computer simulation). Their light has taken 13 billion years to reach Earth.
Yes. 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.
The OBSERVABLE Universe has a diameter of about 93 billion light-years. "Observable" means that the light of anything beyond that hasn't had time to reach us, since the time of the Big Bang.
Over time - billions of years - galaxies will merge with other galaxies. In about 3 billion years, the Andromeda galaxy will merge with our own galaxy, the Milky Way.However, the separation between galaxies is so great, that not all galaxies will merge unless the fundamental issue of the amount of mass in the Universe is determined.If we live in a "contracting universe" then eventually all galaxies will merge.
Yes. To be more exact, it is "space" within the "observed universe" that is expanding. A confusing fact is that many astronomers believe the universe as a whole may already be infinite in size. This doesn't stop them saying the observable universe is still expanding. "Infinity" is a tricky idea.
Deep space generally refers to regions of the universe beyond our solar system, extending to the farthest reaches of galaxies and intergalactic space. While there is no definitive boundary, deep space encompasses distances of billions of light-years, where galaxies, cosmic structures, and dark matter exist. The observable universe itself is estimated to be about 93 billion light-years in diameter, but the entire universe may extend far beyond that, potentially infinitely. Thus, deep space is essentially limitless in terms of distance and scale.
There are an estimated 1011 (100 billion) galaxies in the observable Universe. It is not known how much bigger the Universe is, compared to the observable part.
at least 100 billion or more.
The observable Universe has somewhere around 1011 galaxies. The entire Universe is much larger than the observable Universe, but currently, it is not known exactly how much larger. It might be infinite in size, but in any case, it is estimated that the Universe is a lot larger than the observable Universe.
WikiSky will not map all 100 billion galaxies in the observable universe
Assuming the questioner meant "how many", the present estimate is: between 100 billion and 200 billion galaxies, in the observable Universe.
There are about 1011 galaxies on the observable Universe. The actual Universe is much bigger, but nobody knows how much bigger. Answer2: Thee are >1012 galaxies in the universe.
There are an estimated 1011 galaxies in the observable Universe. The entire Universe is much bigger than the observable Universe. It may be infinitely bigger, but it is not currently known whether this is the case.
It is possible that astronomers will measure all the sizes of 100 billion galaxies in the observable universe.
No, because it will be impossible for the PGC catalog to have at least all 100 billion galaxies in the observable universe.
It is possible that someday astronomers have all J2000 coordinates of 100 billion galaxies in the observable universe.
Someday astronomers may have measured all the distances of 100 billion galaxies in the observable universe.
Someday astronomers may have classified all the shapes of 100 billion galaxies in the observable universe.
