When you see a galaxy 8 billion light-years away you are looking how many years into the past?
When you see a galaxy that is 8 billion light years away, the light that's dribbling into your eye left that galaxy 8 billion years ago, and has been traveling toward you ever since then. If you just happen to see the galaxy explode or turn blue while you're watching it, you'll know that it actually exploded or turned blue 8 billion years ago. Similarly, if the galaxy explodes or turns green tonight, you won't know about that for another 8 billion years from tonight.
What is the farthest galaxy ever observed by Hubble?
The farthest galaxy ever observed by the Hubble Space Telescope is GN-z11, located about 13.4 billion light-years away. This means we are seeing the galaxy as it was just 400 million years after the Big Bang.
What is the distance. Of range of visible light?
The galaxy MACS0647-JD is 13.3 billion light-years away from the Earth and was visible to the Hubble Space Telescope.
How far is Abell 2029?
Abell 2029 is just over a billion light years from us.
What is the nearest galexy?
The nearest major galaxy is Andromeda which is only 2.5 million light years away. There are two dwarf galaxies near the Milky Way called the Large Magellanic Cloud and the Small Magellanic Cloud roughly 75,000 light years away.In about 2.5 billion years, Andromeda and the Milky Way will merge.
An extraterrestrial being in galaxy B discovered galaxy A was 8 billion light years away If galaxy B is approximately 13.5 billion years old when did galaxy A emit the light that ET observes?
8 billion years ago.
Which is the further most galaxy?
The galaxy that is the farthest away is the MACS0647-JD. It is 13.3 billion light years away.

How far is the baby boom galaxy?
The "baby boom" galaxy is approximately 12.2 billion light years away from us.
Ten years ago astronomers found a galaxy that you know is 8 billuon light years away If the universe were now 15 billion yrs old when would the galaxy have emitted the light you observed?
8 billion years ago.
How far is the Andromeda Galaxy?
At the current estimates, the Andromeda Galaxy is about 2.54 million light years from us, and getting closer every year. At that rate, it is expected to "merge" not "collide" in about 4.5 billion years.
How far is the Andromeda Galaxy from Earth in Light Years?
The Andromeda Galaxy is approximately 2.537 million light-years away from Earth. It is the nearest spiral galaxy to the Milky Way and is on a collision course with our galaxy, expected to merge in about 4.5 billion years.
What galaxy is 60 light years away?
There is no such galaxy, the nearest galaxy is over 2 million light-years away.
How do astronomers observing distant galaxies talk about looking backward in time?
The speed of light is not infinite. Light takes time to travel from distant galaxies to our eyes here on Earth. If a galaxy is 1 billion light years away, it has taken 1 billion years for the light emitted by said galaxy to reach us here, so (obviously) we are seeing the light emitted 1 billion years ago. In a sense, we are seeing 1 billion years into the past at the light emitted by that galaxy.
What are the estimated distances of the background galaxies of the NGC 3370 galaxy?
up to 13 billion light years away.
What are the estimated distances of the background galaxies of the NGC 1614 galaxy?
up to 13 billion light years away.
