M42 - Orion Nebula
The Orion Nebula (M42) is a diffuse nebula located in the constellation Orion. It was discovered by Nicholas-Claude Fabri de Peiresc in 1610 and later cataloged by Charles Messier in 1769. M42 is one of the brightest nebulae in the sky and can be seen with the naked eye.
M42 spans about 24 light-years across and contains a rich population of young stars, including the Trapezium, a group of four massive stars. The nebula is approximately 1,344 light-years away from Earth and has an apparent magnitude of 4.0, making it a popular target for amateur astronomers.

The graph is structured with the vertical axis showing the hours of the day, ranging from 12 AM to 12 AM the next day, while the horizontal axis spans each day of the year.
The reddish shaded area indicates the periods when the M42 is above the horizon, visible to observers. The white line marks the times when the celestial object reaches its highest point in the sky each day, known as the transit.
