There are trillions of galaxies in the universe. This is the time of year when many galaxies are visible in backyard telescopes and the observatory’s telescopes. Due to light pollution and humidity, they are often difficult to see. Galaxies are faint and their light is diffuse, making them a challenge for many observers. The Andromeda Galaxy, the only one that is visible with just your eyes, requires pristine skies with no light pollution. It is located in the Andromeda constellation, which is not in the nighttime sky currently.
