That’s incredible. Illustrates how incomprehensibly big galaxies really are. There’s a thing 2.5 million light years away which still appears 4x bigger than the Moon.
Very much incomprehensible, not only for outer celestial objects since we most probably will never fully discover our own physical earth planet or human body, let alone our thinking brain and our elusive consciousness.
Andromedia the closest galaxy to Milky Way (MW) is estimated to have one trillion stars while MW itself is estimated to have 250 billions. God really knows how many of them really exist and who's counting anyway? It's a blind faith at its worst to pretend we know the numbers since it's most likely that the earth and its sun bound astronomers (including the farthest distance ever Voyager spacecraft) are several orders of magnitudes off the marks.
It's also estimated that's more than a trillion number of stars inside the two galaxies (Andromeda and MW), not number of planets, not even the number of moons (the very title of this HN post).
Overall it's also estimated that there's more than a trillion number of galaxies (not stars) inside our universe.
To make matter even more complicated, all of these celestial objects are moving in very high speed relative to each others and none is static. These galaxy are millions or billions light years away from earth and by the time their EM signals has reached earth, they probably have already dissappeared or morphed into something else.
How about non observable part of the universe?
How about other parallel universes that physicists claim to exist?
My personal conclusion to this mind boggling facts is that to assume and conclude there is only earth that has living creatures is very much premature and naive.
