The chemical element lithium is predicted to have been created by the Big Bang, 13.8 billion years ago. Observations of Nova Centauri 2013 show that lithium has been found for the first time in material ejected by a nova, helping to explain the mystery of why many young stars seem to have more of this chemical element than expected.

This new NASA/ESA Hubble Space Telescope image shows the Lagoon Nebula (Messier 8) an object with a deceptively tranquil name. The region is filled with intense winds from hot stars, churning funnels of gas, and energetic star formation, all embedded within an intricate haze of gas and pitch-dark dust.
Brown dwarfs are relatively cool, dim objects that are too massive to be planets, yet they are too small to sustain hydrogen fusion reactions. By observing a brown dwarf 20 light-years away, researchers have found another feature that makes these so-called failed stars more like supersized planets — they host powerful aurorae near their magnetic poles.
Like graffiti sprayed by an unknown artist, unexplained narrow, arc-shaped, reddish streaks are visible on the surface of Saturn’s icy moon Tethys in new, enhanced-colour images from NASA’s Cassini spacecraft. The red arcs are among the most unusual colour features on Saturn’s moons to be revealed by Cassini’s cameras.
