Astronomy Picture of the Day 🔭 -- Comet Leonard and the Whale Galaxy -- Sweeping through northern predawn skies, on November 24 Comet Leonard (C/2021 A1) was caught between two galaxies in this composite telescopic image. Sporting a greenish coma the comet's dusty tail seems to harpoon the heart of NGC 4631 (top) also known as the Whale Galaxy. Of course NGC 4631 and NGC 4656 (bottom, aka the Hockey Stick) are background galaxies some 25 million light-years away. On that date the comet was about 6 light-minutes from our fair planet. Its closest approach to Earth (and even closer approach to Venus) still to come, Comet Leonard will grow brighter in December. Already a good object for binoculars and small telescopes, this comet will likely not return to the inner Solar System. Its perihelion, or closest approach to the Sun, will be on January 3, 2022. -- Image Credit & Copyright: Gregg Ruppel

Hello Omer, I am wondering if you are watching these images from a telescope. Because you do not share outside the galaxy, is this your profession?
Hello Nurcanca, No, I am just interested in astronomy as a hobby. It is not my profession. Most of these pictures are from other astronomers. I usually put copyright information at the end of description. I wish that I can watch the stars and galaxies myself through a telescope. The problem is that I live in a city where there is so much "light pollution".
I would like to look at the sky with a telescope too
