M17: Rise, Set, Nighttime Path
M17 Daily Motion
M17 will be visible until October, 18, when it will move too close to the Sun. During this time, its proximity to the Sun will cause it to disappear from the night sky, making it unobservable for a while.

M17 - Omega Nebula
The Omega Nebula (M17), also known as the Swan Nebula, is an emission nebula located in the constellation Sagittarius. It was discovered by Philippe Loys de Chéseaux in 1745 and later included in Messier's catalog in 1764. The nebula is a region of active star formation.
M17 spans about 15 light-years across and is illuminated by a group of young, massive stars. The nebula is approximately 5,000 light-years away from Earth and has an apparent magnitude of 6.0, making it visible with binoculars or a small telescope.

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 M17 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.
