A
Nice Surprise
With
the smoke from the forest fires starting to move back in, I decided
to take a chance at imaging anyway. I couldn't smell the smoke,
making me think either 1) my sinuses are stopped up, or 2) the smoke
was not a ground level. I'm a little leery of opening the observatory
with the smoke, fearing the smoke could ruin the anti-reflective
coatings on the corrector plate (on the front of the scope). I had
planned on imaging something else instead M77, but I'm glad I settled
on M77.
As
you can see, M77 is a galaxy, located in the constellation of Cetus.
Cetus was the mythical sea monster, but today the constellation is
generally called the Whale. The galaxy is about 47 million light
years away and contains an active nucleus. An active galactic nucleus
is believed to be the result of matter “falling” into a super
massive black hole at its center. When the matter falls in, it
radiates massive amounts of electromagnetic energy in many bands.
Bands, in this case, refers to the visible wavelengths band, and/or
radio, microwave, gamma ray, x ray or many other wavelengths of
electromagnetic energy. M77 is also classified as a
Seyfert galaxy, which is a classification I'm not really familiar
with. A chance for more study.
