The peak surface brightness of the central region of M42 is about 17 Mag/arcsec 2 and the outer bluish glow has a peak surface brightness of 21.3 Mag/arcsec 2. [ 9 ] The Orion Nebula contains a very young open cluster , known as the Trapezium Cluster due to the asterism of its primary four stars within a diameter of 1.5 light years.
Stargazing apps are brilliant for spotting constellations in the night sky, looking at the planets, identifying stars, and learning about astronomy.

Charles Messier. The first edition of 1774 covered 45 objects (M1 to M45).The total list published by Messier in 1781 contained 103 objects, but the list was expanded through successive additions by other astronomers, motivated by notes in Messier's and Méchain's texts indicating that at least one of them knew of the additional objects.
Planetarium software is application software that allows a user to simulate the celestial sphere at any time of day, especially at night, on a computer.Such applications can be as rudimentary as displaying a star chart or sky map for a specific time and location, or as complex as rendering photorealistic views of the sky.
