How many light years away is warped galaxy?
ESO 510-G13 is a spiral galaxy approximately 150 million light-years away in the constellation Hydra See:- http://en.wikipedia.org/wiki/File:Warped_galaxy.jpg
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.
When you see a galaxy 8 billion light years away you are how many years into the past?
8 billion light years means that the light has taken 8 billion years to reach you. That's how far into the past you are seeing.
What galaxy is 3 million light years from us?
The Pegasus Dwarf Irregular Galaxy is about 3 million light years from us. See related link for more information. If you were thinking about the Andromeda Galaxy, that is only (!) 2.54 million light years from us.
Are all the stars in the night sky you can see only from the Andromeda galaxy?
No. The only stars you can see are within our own galaxy, the Milky Way. The Andromeda Galaxy is a faint smudge of light 2.5 million light years away, beneath the constellation Cassiopeia. Most of the stars you can see are within a couple hundred light years. A few, like Deneb, are several thousand light years away--and just extremely bright.
Why do photographs of the Andromeda galaxy show it as it was 2.4 million years ago?
The Andromeda galaxy is about 2.4 million light years away, meaning that light from it takes 2.4 million light years to reach us, so the light we see from it now was emitted 2.4 million years ago.
If you look far enough away can you see Earth in the past?
No. If you look far enough away, you will see OTHER objects in the past. For example, if a galaxy is ten million light-years away, the light of this galaxy took 10 million years to reach us, so we see this galaxy 10 million years ago. Earth's light, from millions of years ago, doesn't come back to us, since (roughly speaking) light travels in a straight line, and moves at the speed of light (300,000 km/sec).
Why do scientist study distant galaxies to learn about early galaxy's?
If you look at a distant galaxy, the light from the galaxy has travelled for perhaps a hundred million years, a billion years, or up to an age close to the age of the Universe (13 billion years or so), depending on the galaxy's distance. Thus, the light you see shows you how the Universe was billions of years ago.
Where is the Andromeda Galaxy?
The Andromeda Galaxy (also known as Messier 31 or M31) sometimes as the Great AndromedaNebula is a spiral galaxy approximately 2.5 million light years away in the constellation Andromeda, and is 220,000 light-years in diameter, and contains 1 trillion stars.[See link] For wikisky coordinates[See Link] For constellation directions to the Galaxy.
How far is a spiral galaxy?
The nearest spiral galaxy to Earth is the Andromeda galaxy, 2.5 million light years away. Plus it it the furthest thing you can see with the naked eye!
Can see a supernova explosion on another galaxy?
Actually before the rise of visible light there is a surge in neutrinos that can give a warning of a super-nova by as much as five days. Then comes the light flash in all forms of electromagnetic radiation (including visible light).
Could you see a galaxy that is 20 billion light - years away?
No, since the light cannot reach us at that distance. the space was born 14 billion light years ago and we cannot even see a little spot of 14 billion light years ago which means that we cant see anything that is 20 million light years far.
