Cool pics Dave :thumb:
I use Spitzer and Hubble pics for my background and would love to add yours to the cycle. PM sent |
One sad reality today is that virtually the entire US is bathed in such a bright nighttime light that most people spend most of their lives never really seeing how cool the night sky can really be. Even if you are in a small town it all gets drowned out in a dull grayish off-black with only the brightest stars visible.
You pretty much have to go to someplace like northern Arizona or rural Utah to see the true beauty of the night sky. That actually will probably play a significant role in deciding where I want to retire someday 25-30ish years from now. National Geographic wrote a really cool article about light pollution a couple years or so ago. I go outside, and I just simply don't see stuff like this: http://s.ngm.com/2008/11/light-pollu...ht-sky-615.jpg |
No. No I can't comprehend it.

another interesting picture of the same group of stars. If the image on the right looks familiar to you, believe it or not, that image on the left does exist in some places in the western and northern US farther from cities.

M81 and M82 from last night... 3 hour photo. A American-Canadian team determined the distance to M81 to be 12.9 million light-years ± 0.9 million light-years. So the light I recorded last night happened about 13 million years ago.
Explanation: On the left, surrounded by blue spiral arms, is spiral galaxy M81. On the right marked by red gas and dust clouds, is irregular galaxy M82. This stunning vista shows these two mammoth galaxies locked in gravitational combat, as they have been for the past billion years. The gravity from each galaxy dramatically affects the other during each hundred million-year pass. Last go-round, M82's gravity likely raised density waves rippling around M81, resulting in the richness of M81's spiral arms. But M81 left M82 with violent star forming regions and colliding gas clouds so energetic the galaxy glows in X-rays. In a few billion years only one galaxy will remain. Updated pic... |
I LOVE this shit. I really hope we get to experience Betelgeuse going supernova in this lifetime.

Time to upgrade to a CGE PRO 1400 HD.

I used a CGEM mount to take this one...
