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 happened about 13 million years ago.

The Pacman Nebula or NGC281:
Explanation: NGC 281 is a busy workshop of star formation. Prominent features include a small open cluster of stars, a diffuse red-glowing emission nebula, large lanes of obscuring gas and dust, and dense knots of dust and gas in which stars may still be forming. The open cluster of stars IC 1590 visible around the center has formed only in the last few million years. The brightest member of this cluster is actually a multiple-star system shining light that helps ionize the nebula's gas, causing the red glow visible throughout. The lanes of dust visible left of center are likely homes of future star formation. Particularly striking in the above photograph are the dark Bok globules visible against the bright nebula. The NGC 281 system, dubbed the Pacman nebula for its overall shape, lies about 10 thousand light years distant.

It may have already. If it blew up today we won't see the light for 1400 years. Take your vitamins.

Well, true... but it may have gone Super Nova 1400 years ago as well...

Sorry the Orion nebula, which is about 1400 light years away, is what I was thinking of. You can go to half douses on your vitamins.

New start of a pic for today....
Barnard 33. Known to most people as the horse head nebula. Took me awhile to get a shot of this little guy. Always cloudy when I tried.
