NASA's Swift satellite has acquired the highest-resolution view of the neighboring spiral galaxy M31. Also known as the Andromeda Galaxy, M31 is the largest and closest such galaxy to our own. It's more than 220,000 light-years across and lies 2.5 million light-years away in the constellation Andromeda. Between May 25 and July 26, 2008, Swift's Ultraviolet/Optical Telescope (UVOT) acquired 330 images of M31 at wavelengths of 192.8, 224.6, and 260 nanometers. The images represent a total exposure time of 24 hours. Some 20,000 ultraviolet sources are visible in the image, including M32, a small galaxy in orbit around M31. Dense clusters of hot, young, blue stars sparkle in the disk beyond the galaxy's smooth, redder central bulge. Star clusters are especially plentiful along a ring about 150,000 light-years across.

I really wish NASA could make 1 hours long videos like this. Every time I see "Nasa astrophysics or Nasa Heliophysics, I feel true happiness for knowledge.

Wow. I think about the millions of galaxies out in space and I can't help but wonder just how many worlds there are out there like our own. I can see why space has captured the imaginations of so many.

Today I learnt there are Dwarf Galaxies.

It's really wild to think that every atom in our bodies was forged from an exploding star! We are all star stuff, just walking around and thinking about things!

I had Seen Andromeda in my 60mm telescope four days ago. Seeing it many times and its still beautifull. Imagine how many stars and planets orbit in there. Chances of Life 100%.

This is a gorgeous thing by which I get knowledge about universe

I've been thinking, if the atoms that make up my body were created during the "big bang" 13.7 billion years ago does that mean that I too am 13.7 billion years old??

The entire universe is a huge fractal. It is beautiful and amazing, I agree.

Andromeda is one of several galaxies, from our local group, that can be seen with the naked eye. The light coming from it is blue-shifted meaning that it is approaching towards us in direct collision course and that will probably result in merging (in cca 4 billion years) creating one large elliptical galaxy.

I was just thinking that very same thing :) I can almost guarantee you that there's at least one civilization in the Andromeda Galaxy trying to get in contact with another civilization. Maybe at some point they might get in contact with us here in the Milky Way, who knows

Every Galaxy have its own sun, thats is incredible 😮
|
Incredible , just really incredible where we are on the scale of this universe.
2 |
somewhere in there, there is a civilization looking back at our galaxy
|
to think about that is mind blowing, it's even hard to think if there's someone out even in our galaxy. but there must be !

To think are atoms are going to mix with that beauty one day in the far future. Awesome

Saw this galaxy a few months ago with my own eyes.

Dreaming of Andromeda..

Hello Brothers and Sisters from Andromeda!! Peace and Love be upon you! best wishes to you from a Human Being from Planet Earth in the Milky Way Galaxy! One Love!

A quiet reminder of how ridiculously insignificant we are, and even our planet is, when related to the infinite expanse of the Universe.

Kind of scary to consider just how small the earth is relative to everything out there. Galaxies orbiting galaxies threw me a little.
