Fiery Loops

Via National Geographic

Like tentacles waving in space, large loops of hot gas rise from the nebula NGC 3582 in a new picture from the European Southern Observatory in La Silla, Chile.

The interstellar cloud of gas and dust is an active star-forming region. But as very massive stars live fast and die young, their explosive demises eject material, likely forming the loops. Meanwhile, newborn stars are emitting intense ultraviolet radiation, heating the gas and causing the nebula to glow.
