The Egg Nebula

egg nebulaThe Egg Nebula (aka CRL 2688) is the last gasps of a dying, Sun-like star. This picture superimposes visible light and infrared data from Hubble.

Objects like the Egg Nebula expel carbon and nitrogen—elements crucial for life—into space. Studies of the Egg Nebula show that such dying stars eject matter at high speeds along a preferred axis and may even have multiple jet-like outflows. The signature of the collision between this fast-moving material and the slower, out-flowing shells is the red glow of hydrogen molecules.
