the universe is isotropic & homogeneous, meaning there is no center. the observable universe has a center, which is the part of the universe we can see. we are at the center of the observable universe.

We are at the centre of the observable universe, keyword being 'observable'.
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.
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.
Yes. There are at least 90 billion trillion or more planets in the observable universe.
WikiSky will not map all 100 billion galaxies in the observable 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.
There are estimated to be around 100 billion galaxies in the observable universe, with each galaxy containing hundreds of billions of stars. This means that the total number of stars in the observable universe is in the order of 10^24 (1 septillion) stars.
Roughly about 20%-40% of the observable universe is blocked from Earth's view by the Milky Way and other objects including galaxies. This is because the Milky Way galaxy itself occupies a significant portion of our observable sky, obstructing our view of distant regions of the cosmos.
It is possible that astronomers will measure all the sizes of 100 billion galaxies in the observable universe.
In my opinion, yes. There are at least 10,000 trillion sentient species (100,000 per galaxy) in the observable universe.
