If the enviorment is brightly lit, you may not see the spectrum as it will be too faint compared to the brightly lit background.
Yes. Some faint background galaxies are masked out due to being close to a bright foreground galaxy.
You can see the faint blur of Andromeda by looking near the back foot of Pegasus.
Yes, the Andromeda galaxy can be seen at night with the naked eye from a dark location. It is the closest spiral galaxy to our Milky Way and appears as a faint, hazy patch in the sky.
The Sombrero Galaxy is located 11.5° W of Spica and 5.5° NE of Eta Corvi (in the constellation Corvus). Using the star Gienah in the constellation Corvus there is a chain of faint stars extending upward that will lead to the Sombrero Galaxy.
Yes, the Andromeda galaxy is visible to the naked eye from certain parts of the world. It appears as a faint smudge in the night sky and is best seen in skies with minimal light pollution.
Either a radio galaxy or a quasar
You are simply seeing the Milky Way - our home galaxy. "The Milky Way" is the name of our galaxy, but it's also the name of the faint band of light sometimes visible in the night sky. That band of light is composed of millions of stars too faint to be seen individually without optical aid.
Yes, the Andromeda galaxy is visible to the naked eye from a dark location. It appears as a faint, smudged patch in the sky and is best observed in the fall or winter months in the northern hemisphere. Using binoculars or a telescope can enhance the view of the galaxy.
A faint sound is quiet or barely audible, often requiring careful listening to detect. It may be soft and subtle, making it difficult to hear clearly or distinguish from surrounding noise.
I could be wrong about this, but I don't think it's possible to observe nebulae (properly so called) in any galaxy other than our own, because they're too faint and too far away.
At high resolution, the details of the target can resolve this question. Also, the redshift (change in colour based on speed) can be used to determine distance).
