Posted on 10/10/2013 9:29:30 PM PDT by SunkenCiv
Explanation: This sharp cosmic portrait features NGC 891. The spiral galaxy spans about 100 thousand light-years and is seen almost exactly edge-on from our perspective. In fact, about 30 million light-years distant in the constellation Andromeda, NGC 891 looks a lot like our Milky Way. At first glance, it has a flat, thin, galactic disk and a central bulge cut along the middle by regions of dark obscuring dust. The combined image data also reveal the galaxy's young blue star clusters and telltale pinkish star forming regions. And remarkably apparent in NGC 891's edge-on presentation are filaments of dust that extend hundreds of light-years above and below the center line. The dust has likely been blown out of the disk by supernova explosions or intense star formation activity. Faint neighboring galaxies can also be seen near this galaxy's disk.

has “day” been redefined too?
How are you getting these? I thought NASA was shut down, and that their essential personnel were off doing Muslim outreach and giving secrets to the Russians.
Hey, we’re way behind, there was no APoD for over 4 billion years before this started.
Making this comparison shows what a wonderful mind you have.
All I can say is “WOW!”
Yes very perceptive.
“Faint neighboring galaxies can also be seen near this galaxy’s disk.”
Some of them are not so neighboring, I think. But it amazes me, looking at these photos, how many distant galaxies show up. They’re everywhere.
The universe is kinda big.
:’) There’s a backup page — on the very same server of course — so I’ve been using those and just adjusting links and pointers.
