How far is Pluto from earth in light years? How far is the Sun from Earth? How far away is Canis Minor from Earth? How many light years away is the Andromeda Galaxy? How far is the Earth from the Sun? How far are the outer planets from the Sun?
at a meeting of the American Astronomical Society, a colleague presented a paper on his behalf that made a groundbreaking claim: the Andromeda Nebula (M31) was nearly a million light-years away. This distance placed it far beyond the Milky Way, proving that our galaxy was not...

To understand how telescopes work, let's ask the following question. Why can't you see an object that is far away? For example, why can't you read the writing on a dime when it is 150 feet away with your naked eyes? The answer to this question is simple: the object does not...
Our Milky Way galaxy is approximately 100,000 light-years across (~588 quadrillion miles). Moving further into our Universe, our nearest neighbor, theAndromeda galaxyis 2.537 million light-years (14.7 quintillion miles) away from us. The Andromeda Galaxy is 2.537 million light-years away from us...
More finely structured, multi-armed galaxies like the Milky Way galaxy and its neighbor Andromeda appeared much later, when the universe was 8 billion years old. Next, the researchers plan to analyze other surveys, to get a broader picture of galaxies as a whole, including their overall masses...
Our neighboring galaxy, Andromeda, is a cold-blooded killer and a cannibal to boot. In about 4 billion years it’s going to collide with The Milky Way, eat it, and litter the cosmos with its crumbs. This won’t be the first time it’s killed. ...
