M81 and M82

Imaged by Jean-Yves Beninger from Ollioules, France on 6 January 2024



On the right side of the image is M81, also named Bode's Galaxy. To the left the diminutive companion is M82, or the Cigar Galaxy.
M82 stands out as a starburst galaxy, distinguished by its accelerated star formation rate, believed to be the result of a close interaction with the more massive galaxy. Furthermore, M82 exhibits a superwind, a substantial expulsion of material, which is likely propelled by the intense star formation within it.
These celestial bodies are located roughly 12 million light-years from Earth.
