M77 Galaxy

Reprocessed 1/4/05

This galaxy is located in the Cetus (The Whale) constellation and is approximately 60 million light years away. The photons that fell upon the ccd chip to make up this image were created around the time that dinosaurs roamed the earth!

This is a small spiral galaxy seen face on, one of the so called Seyfert galaxies, which in this case means it has a radio source probably caused by matter falling into a black hole. It is receding from us at about 1100 miles per second. Actually saying this is a small galaxy is a misnomer. It looks small but in fact it is very large. When you include the outlying gasious areas it's about 170,000 light years across. Almost twice as large as our Milky Way.

This image was taken from my front driveway on 11/13/04 at 1:00 am est with my new atk-2hs webcam. The small image below is with some false color added. The negative image beside it shows that M77 is larger than it first appears and in fact, its gasious envelope is almost as big as the galaxy itself.
