This is a newly released Hubble image of the Lagoon Nebula, otherwise known as Messier 8 and the star cluster NGC 6523. It lies 4,500 light-years away in the constellation Sagittarius. Image credit: NASA, ESA, J. Trauger (Jet Propulson Laboratory).This new NASA/ESA Hubble Space Telescope image shows the Lagoon Nebula, an object with a deceptively tranquil name. The region is filled with intense winds from hot stars, churning funnels of gas, and energetic star formation, all embedded within an intricate haze of gas and pitch-dark dust.
Studying giant galaxy clusters to find targets for the upcoming James Webb Space Telescope, the Hubble Space Telescope spotted what appears to be a third supernova going off in a galaxy where two others were previously seen.
Examples of colliding galaxies are commonplace, but chance alignments showing apparent collisions between widely separated galaxies are more rare, but equally spectacular.
Taking a second look with a more powerful camera, Hubble reveals thousands of emission nebulae in an oddball irregular dwarf galaxy 17 million light years from Earth
