What else can I help you with?
Are there at least 90 billion trillion planets in the observable universe?
Yes. There are at least 90 billion trillion or more planets in the observable universe.
How do astronomers locate other stars trillion light years away?
They can't. The universe is only about 13 billion years old. If there are galaxies a trillion light years away their light has not reached us yet and due to the expansion of the universe, never will. At the edge of what we call the observable universe we cannot make out individual stars, but we can detect galaxies using infrared telescopes.
How many months would it take to count all the stars in our universe since there are 10 billion trillion of them?
If you counted 1 number per second, it would take 4000 trillion months (320 trillion years) to count all 10 billion trillion stars (100 billion per galaxy) in a fictitious version of our universe.
What does observable universe mean?
The observable universe refers to the portion of the universe that can be seen from Earth, limited by the distance light has traveled since the Big Bang, approximately 13.8 billion years ago. This region encompasses all celestial objects whose light has had enough time to reach us, creating a spherical boundary around our planet. Beyond this boundary, there may be more universe that we cannot observe due to the finite speed of light and the expansion of space. The observable universe is estimated to be about 93 billion light-years in diameter.
How many years would it take to count 10 billion trillion stars in the universe?
If you counted at the rate of one number per second, it would take 320 trillion years to count to 10 billion trillion. It makes no difference WHAT you're counting.
Are there at least 90 billion trillion planets in the observable universe?
Yes. There are at least 90 billion trillion or more planets in the observable universe.
How many galexys in the univers?
The observable universe is estimated to contain 200 billion to 2 trillion galaxies
Will astronomers make a catalogue for at least 90 billion trillion planets in the observable universe?
Unlikely, because that number is only someone's estimate.
What is this number 1000000000000000000000?
1,000,000,000,000,000,000,000 = 1021 = 1 sextillion
Will WikiSky map all 100 billion galaxies in the observable universe?
WikiSky will not map all 100 billion galaxies in the observable universe
Will astronomers make a catalogue for at least 18 billion trillion Earth-like planets in the observable universe?
Unlikely, because that number is only someone's estimate.
Can astronomers get all 100 billion redshifts for all 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.
Will astronomers measure all the sizes of 100 billion galaxies in the observable universe?
It is possible that astronomers will measure all the sizes of 100 billion galaxies in the observable universe.
Are all 100 billion galaxies in the observable universe up to 13.5 billion light-years away?
Yes, all 100 billion galaxies in the observable universe up to 13.5 billion light-years away.
How many galaxies are there in your 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.
How can astronomers make an atlas of at least 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.
Will the PGC catalog have at least all 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.
