The NGC 1977 Nebula ("The Running Man")

NGC 1977 is a blue reflection nebula in the constellation Orion, located half a degree northeast of the Orion Nebula. Together with NGC 1973 and NGC 1975, it forms part of the same gas and dust cloud, which reflects light from nearby stars and is intersected by dark dust clouds.

The nebula consists of gas and dust illuminated by young, hot stars, particularly the triple star system 42 Orionis (42 Ori). This star has a mass about 12 times that of the Sun and a surface temperature of approximately 25,400 K. Observing the nebula requires a telescope with a primary mirror diameter of at least 100 mm and a dark, clear night. The best time for observation is from November to March, when the constellation Orion is visible first in the night sky and later in the evening sky.

The nebula is often photographed together with the Orion Nebula, as they can both fit within the same field of view.
