DR_6_nebula
DR 6 is a cluster of stars in the Milky Way galaxy, composed of dust, gas, and about 10 large newborn stars, each roughly ten to twenty times the size of the Sun.[3] It was discovered by astronomers at NASA with the Spitzer Space Telescope, viewing the nebula using infrared light.[2][3]
The areas of the cluster that appear green are mainly composed of gas, while the parts that seem to be red are made of dust.[3]
The DR 6 nebula is located about 3,900 light-years away in the constellation Cygnus. The center of the nebula, where the ten stars are located, is roughly 3.5 light-years long,[4] roughly equivalent to the distance between the Sun and Alpha Centauri, the closest star to the Sun.[3]
