Green Glow of ‘Mesospheric Ghosts’ Decoded

Science and Nature
December 12, 20233 minutes checked outMystical green screens in the sky called "mesospheric ghosts" can in some cases accompany the remarkable red climatic lights called spritesBy Meghan BartelsRed sprites above a supercell thunderstorm as lightning brightens the cumulonimbus cloud listed below near Hay Springs, Nebraska. If you're ever fortunate sufficient to find the climatic drama of a red sprite, look carefully, and you might see green radiance that talks to Earth's position in the planetary system and clarifies a mystical layer of our world's environment.That's according to scientists who analyzed the source of an odd phenomenon called "mesospheric green emissions from fired up oxygen in sprite tops," or, more informally, "mesospheric ghosts."The mesosphere is a layer of the environme...

JWST releases brand-new picture of well-known supernova residue– with a twist

Science and Nature
NASA has actually launched a brand-new picture of supernova residue Cassiopeia A (Cas A) taken by the James Webb Space Telescope (JWST). JWST utilized its Near-Infrared Camera (NIRCam) to image Cas A in a various method, regardless of it being amongst the most well-studied supernova residues in the universes. [Related: An amateur astronomer spotted a new supernova remarkably close to Earth.] Cas A has to do with 11,000 light-years far from Earth in the constellation Cassiopeia. It is made from the remains of enormous star that astronomers think blew up about 340 years earlier. Ever since, NASA's Chandra X-Ray Observatory, the Hubble Space Telescope, and now retired Spitzer Space Telescope put together a multiwavelength image of the remains of the outstanding surge. JWST allowed astro...
