Young blue stars circling the galactic center dominate the Andromeda Galaxy in this image taken in ultraviolet! About 2.5 million light-years away, the Andromeda Galaxy, also known as M31, really is our galactic neighbour. Spanning about 230,000 light-years, it took 11 different image fields from NASA’s Galaxy Evolution Explorer (GALEX) satellite telescope to produce this gorgeous portrait of the spiral galaxy in ultraviolet light in 2003. Its spiral arms stand out in visible light images, Andromeda’s arms are sites of intense star formation. They have been interpreted as evidence that Andromeda collided with its smaller neighboring elliptical galaxy M32 more than 200 million years ago. The Andromeda galaxy and our own comparable Milky Way galaxy are the most massive members of the Local Group of galaxies and are projected to collide in several billion years – perhaps around the time that our Sun’s atmosphere will expand to engulf the Earth.

The Milky Way Might Never Become An Elliptical Galaxy
“We will continue to slowly form new stars for many trillions of years. Our Local Group won’t become “red and dead” for many times the present age of the Universe. And, perhaps most importantly, we’ll still have a Milky Way-like feature in the night sky of whatever planets are around in the far future. There may come a day where our spiral features are no more. But since the turn of the century, we’ve learned that day won’t come when the Milky Way and Andromeda merge, but rather much farther out into the distant future.”
In about 4 billion years, the Milky Way and Andromeda will merge. Gravitational interactions will trigger the collapse of gas, new stars will form, stellar winds will blow, gas will get ejected, stars will be gravitationally disrupted, and our galaxy will transition from a spiral to an elliptical. Devoid of gas, our post-merger galaxy, now named Milkdromeda, will become what’s known as “red and dead.”

Hey all,
I’m Robert Hewitt Wolfe, writer of things like #Elementary #StarTrek #DS9 #Andromeda, etc etc, and author of the BILLY SMITH AND THE GOBLINS books.
I may end up moving here from Twitter if Grimes’ Baby Daddy lets the Orange Menace back onto Twitter. Because eff that noise. I’m not providing content to support that nonsense.
If you have questions about #TVWriting #NovelWriting or any of that kind of thing, feel free to ask and I’ll answer (assuming that’s even a thing on Tumblr).
I also talk about geek culture in general. Comic books, TTRPGs, all that kind of thing.
This has been a test of the Emergency Twitter Escapee Broadcasting Network.
