Explanation
Let us talk about the explanation of this picture, like if you look in the upper sky and see a group of stars that are as big as the full moon, that is the Pleiades (M45). Perhaps it is the most famous star cluster in the sky. These are the brightest stars that can be seen even in light-polluted cities.

If you look at this entire structure from the right side, it is surrounded by a reddish glow, which is a very abundant element of the universe, which is hydrogen. This feature image has been composed of 25 hours of exposure, which was captured last year through Starfront Observatory in Texas, USA.

MarsyFact of the Day
Did you know?
Â
There’s a star cluster called Messier 80 (M80) in the constellation Scorpius that is very densely packed, one that contains hundreds of stars within its region, just a few dozen light-years across.
Â
This is the most crowded star cluster inside our galaxy. Imagine the stars that are very close to the planet you live on and the planets that are among those stars. Your night sky will never be dark; it will glow with starlight 24/7.
