What galaxy is a billion light years away?

What galaxy is a billion light years away?

GN-z11 is currently the oldest and most distant known galaxy in the observable universe, having a spectroscopic redshift of z = 11.09, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).

Could we see a galaxy that is 25 billion light years away?

-No, because it would be beyond the bounds of our observable universe. -No, because a galaxy could not possibly be that far away. No, because it would be beyond the bounds of our observable universe. -one-third of the age of the universe.

Can we see a galaxy 50 billion light years away?

Could we see a galaxy that is 50 billion light-years away? A. No, because it would be beyond the bounds of our observable universe.

What galaxy is 13.3 billion light years away?

Also in 2004, a team using both the Hubble Space Telescope and the Keck Observatory discovered a galaxy that is believed to be about 13 billion years away from us. It was found when observing the galaxy cluster Abell 2218. The light from the distant galaxy was visible because of gravitational lensing.

How long will the universe live?

22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if Higgs boson field is metastable.

Can we look back in time?

This ability to look back in time is based on the fact that even light has a speed limit. It bowls along at 186,000 miles per second. So if you look at a star that is 30 light years away, that is what it looked like 30 years ago. The same applies to stars that are millions of light years away.

How old is the oldest galaxy in the universe?

This level of redshift indicates that this galaxy existed as observed roughly 13.4 billion years ago – aka just 400 million years after the Big Bang. At this distance, GN-z11 is so far that it defines the very boundary of the observable Universe itself!

Which is the farthest galaxy in the universe?

In this case, the research team used the Keck I telescope at Maunakea, Hawaii, to measure the redshift of GN-z11 to determine its distance. The results they obtained indicated that it is the farthest (and oldest) galaxy ever observed. As Kashikawa explained in a University of Tokyo press release :

How long is GN-z11 32 billion light years away?

That puts GN-z11 about 32 billion light years away. Because expansion of the universe over billions of years makes distance calculation complex, astronomers generally represent distance as a function of time -how long it takes light rays originating at a given object to reach us.

How old is the universe according to astronomers?

“The light that left this galaxy that we’re observing now left the galaxy 13.4 billion years ago,” said Gabriel Brammer, an astronomer at the Space Telescope Science Institute in Baltimore and the study’s second author. “As far as we know, the universe itself is about 13.8 billion years old.
