Coddington's Nebula

Large spiral galaxies often seem to reap all the glory by displaying their young, bright, blue star clusters in beautiful, symmetrical spiral arms. But small, irregular galaxies also form numerous new stars. Indeed, the dwarf galaxy IC 2574 in its treacherous pink regions with glowing hydrogen gas shows clear indications of an intensive star formation. Similar to spiral galaxies, the turbulent star-forming regions in IC 2574 are traversed by stellar winds and supernova explosions, which hurl material into the interstellar medium of the galaxy and trigger further star formation. IC 2574 is only 12 million light-years away from the Earth and belongs to the M81 group of galaxies that can be seen in the direction of the northern constellation Ursa Major. The beautiful island universe, also known as Coddington's Nebula, is about 50,000 light years in diameter and was discovered in 1898 by the American astronomer Edwin Coddington.
