This beautifully blue image comes from Manuel Fernández Suarez—an award winning astrophotographer. It provides a window into the heart of a stellar nursery, found approximately 3,000 light-years from Earth in the Cepheus constellation.
Called NGC 7822, it lurks on the outskirts of a behemoth molecular cloud (one of the largest in our galaxy), and contains numerous features, like the star cluster known as Berkeley 59, along with one of the hottest stars in our local part of the galaxy—called BD+66 1673 (there, temperatures can exceed 45,000 K).
As we noted before, “The region, formally known as NGC 7822, contains hundreds of newborn stars that are leaving their own mark on the interstellar material surrounding them, seeding it with heavy elements that will ultimately collapse to give life to a new generation of stars. These same stars are also slowly chipping away at some of the material, they in turn, give it its distinct shape and its designation as an emission nebula.”
