Hubble Space Telescope Necklace Nebula
This aptly named ‘Necklace Nebula’ located 15,000 light-years away was captured by NASA / ESA’s Hubble Space Telescope in the constellation Sagitta (the Arrow). Classified as PN G054.203.4, this nebula consists of a pair of tightly orbiting Sun-like stars where one of them expanded and engulfed its smaller companion around 10,000 years ago, creating something astronomers call a “common envelope.”

New Giant Volcano Mars Noctis
Scientists announced the discovery of a new giant volcano on Mars located near the planet’s equator, an area that has been imaged repeatedly by orbiting spacecraft since Mariner 9 in 1971. The region is known as Noctis Labyrinthus (Labyrinth of the Night) and could also contain a buried sheet of glacier ice, making the site an attractive option in the search for signs of ancient life.
