No, because it will be impossible for the PGC catalogue to list all 100 billion galaxies in the observable universe.
WikiSky will not map all 100 billion galaxies in the observable universe
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.
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 astronomers to make an atlas of at least 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.
No, because it will be impossible for astronomers to get all 100 billion redshifts for all 100 billion galaxies in the observable universe.
Yes, all 100 billion galaxies in the observable universe up to 13.5 billion light-years away.
It will be impossible for the Aladin Sky Atlas to 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.
