Description |
A fine double of face-on and
edge-on spiral galaxies. Bright mag 8.9 M77 on the left measures 6' x 7',
much larger than the apparent visual 2' diameter that was first recorded
by Méchain in 1780. It is a giant galaxy of the Seyfert type with more
than a trillion solar masses. At 70 million lightyears it is also the most
distant Messier object. Dusty, spindle shaped NGC 1055 on the lower right
belongs to the same group as M77. The field of view measures approx.
26' x 44'. |
