New research clarifies that the use of stratospheric aerosol injections (SAI)—tiny sunlight-reflecting particles dispersed in the atmosphere—could be a very bad idea. SAI is a theoretical technique to cool down our rapidly warming planet. The theory is that, akin to volcanic eruptions, these particles in the upper atmosphere would reflect some of the sunlight away […]
First 3D Map of an Exoplanet’s Atmosphere Reveals Bizarre Weather
Astronomers have uncovered the secrets of an alien atmosphere on an exoplanet far beyond our Solar System, and it’s unlike anything we’ve ever seen before. In a scientific first, an international team of astronomers has 3D mapped the atmosphere of planet WASP-121b, also known as Tylos. Using the European Southern Observatory’s Very Large Telescope (yes, […]
