The farthest parts of the observable Universe are getting away from us at several times the speed of light. LOCALLY, the objects (like galaxies) move at speeds below the speed of light, but in this case, it is space itself that is expanding, faster than the speed of light.
There are at least 20 billion lenticular galaxies in the observable universe, at distances up to 13 billion light years.
There are at least 15 billion elliptical galaxies in the observable universe, at distances up to 13 billion light years.
There are at least 5 billion irregular galaxies in the observable universe, at distances up to 13 billion light years.
There are at least 20 billion lenticular galaxies in the universe.
There are at least 15 billion elliptical galaxies in the universe.
There are at least 5 billion irregular galaxies in the universe.
Yes. There are at least 90 billion trillion or more planets in the observable universe.
The universe definitely has more than one black hole. Just in our galaxy alone there's an estimated 100 million of them, and the observable universe has at least 100 billion galaxies.
There at least 60 billion spiral galaxies in the universe because the spiral galaxies comprise of about 60 percent of all galaxies which are about 100 billion.
If you counted 1 galaxy per second, it would take ~3200 years to count all 100 billion galaxies in the universe.
No, because it will be impossible for the PGC catalog to have at least all 100 billion galaxies in the observable universe.
In my opinion, yes. There are at least 10 billion trillion Earth-like planets in the observable universe.
