Talk about bling! A giant “necklace” glowing brightly in space is the centerpiece of a new photo from NASA’s Hubble Space Telescope.
The cosmic object, which is appropriately named the Necklace Nebula, is a recently discovered planetary nebula, made up of the glowing remains of an ordinary, sun-like star. The Necklace Nebula is located about 15,000 light-years away in the constellation Sagitta.
Planetary nebulas form when stars similar to our sun deplete their store of hydrogen fuel. The stars’ outer layers expand and cool, creating a massive envelope of dust and gas. Radiation flowing out from the dying star ionizes this envelope, causing it to glow.
