Everything We Know About The Andromeda Galaxy

Andromeda is 2.5 million years away and yet when we look up at the night sky chances are you can see it with your naked eye. What do we know about this neighboring galaxy?

Andromeda Galaxy Is Surrounded by a Supersized Gas Halo
"One of the Milky Way's closest galactic neighbors is surrounded by a much bigger halo of gas than previously thought, new observations from the Hubble Space Telescope reveal."

Hubble's High-Definition Panoramic View of the Andromeda Galaxy
"The largest NASA Hubble Space Telescope image ever assembled, this sweeping bird's-eye view of a portion of the Andromeda galaxy (M31) is the sharpest large composite image ever taken of our galactic next-door neighbor."

Andromeda Galaxy Will Collide With Milky Way
"Andromeda galaxy will actually collide with the Milky Way in about 2 billion years, according to the most recent Hubble Space Telescope measurements of the motion of Andromeda and the Milky Way."

1 billion years?! Yea can't wait to witness that. -_-

Andromeda will reach us in 4 billion years? By then, the sun will have ended all life on Earth roughly 1.2 billion years ago. 
Mars may still be around at that point; although, more desolate than it was before. - We should move planets.

"We're gonna bang."
Well then report to the ship asap Julia. We'll bang okay

[junezhang]

"We're gonna bang" really caught my attention and imagination,  Julia you naughty girl!

This is why aliens won't talk to us. Cause we're so amazed by the outside world while every day we wake up, we make ours the shittiest of them all.

The time period when our galaxy and andromeda galaxy collides is on my "must visit" list in the event of time travel being discovered in my time.

The cool thing about this, which is unfortunate since we wont be around, is that one day you'll be able to see Andromeda quite brilliantly during the night sky.

Quarter to half a *trillion*, NOT a quarter to half a billion.

Q: if The andromeda Galaxy lies 2, 5 million light years away, doesen't that just mean that, how we see Andromeda now, is just how far away it was 2, 5 million years ago, or can we actually see where andromeda is right now since it is moving towards us?. pleas anwser :D

[elijahclevenger]

it is amazing how small we really are. makes you think how huge and infinite space is

[Jaconllllll]

I miss my home :')
Nice to know I'm only a few light years away. We are neighbors, after all. 😋

The atoms in my body were formed in supernovae that occurred billions of years ago. The centers of those supernovae should have formed neutron stars and there should be nebulae around those neutron stars. Do we know which neutron stars are most likely candidates for these supernovae that created the atoms that we are made of? Just trying to figure out where "home" is.

We will learn much more in Mass Effect 4!

I love space exploration. The problem is the more questions we ask, the more questions we have 😑

All I remember is that she said, “we’re gonna bang!”

I'd actually like to know more about that EM drive that NASA has been testing, and been saying it's showing promise.

Everything we know about andromeda



that it exists

[commandZee]

Please don't say "we're gonna bang", it's hard enough concentrating during your episodes as it is– especially with those red waves looking so tight ;)

Hey DNews, why do onions make you cry ?
