Search results for exoplanet

A rocky planet with Earth-like temperatures just 11 light years away from us caused quite a stir when it was discovered last year. Its close proximity and potential to harbor alien life made it a good candidate for further study, and scientists continuing to poke around this pocket of the universe are continuing to unravel its mysteries, with new findings shedding further light on its comp
NASA's Transiting Exoplanet Survey Satellite (TESS) mission took its first image as it completed a dramatic lunar flyby this week. On May 17, 2018, the next-generation planet hunter passed within 5,000 mi (8,000 km) of the Moon to execute a slingshot maneuver that hurled it towards its final orbit, where it will spend at least two years making a full-sky survey in search of planets beyond
An important arm of exoplanet research involves the study of the atmospheres that surround these distant worlds. The molecules they hold can reveal valuable insights into what kind conditions can be found there – along with ones that cannot. Such is the case for scientists studying WASP-96b, who are now claiming to have discovered the first exoplanet to be free of clouds... Continue Readin
Astronomers may have discovered almost 4,000 planets beyond our Solar System so far, but trying to image these worlds is a bit like trying to get a good look at a fly buzzing around the Sun. Described as the world's largest and most advanced superconducting camera, a new instrument dubbed DARKNESS is designed to filter out the blinding light of host stars to see orbiting exoplanets in more
Common, relatively cool and potentially life-supporting, red dwarf stars are of particular interest to astronomers hunting down distant worlds. The latest study of Kepler data has now identified 15 new exoplanets around red dwarfs, including a system of three "Super-Earths" – one of which appears to be orbiting within the host star's habitable zone...Continue Reading Potentially habitable Sup
Water is not only a key ingredient in supporting life, it's also a major clue as to how planets form, and NASA has found a lot of the stuff in the atmosphere of a giant exoplanet called Wasp-39b. The planet is as massive as Saturn but has three times as much water as the famous ringed planet. Although this "hot Saturn" is far from habitable, it does provide insights into the wide variety of p
While the Search for Extraterrestrial Intelligence (SETI) program is content to scan the skies for signals that might indicate the presence of life on other planets, the related program Messaging Extraterrestrial Intelligence (METI) aims to take a more active approach. METI and other organizations have now beamed radio transmissions, containing snippets of music, to a potentially-habitable pl
An international team of astronomers has discovered a temperate Earth-sized world with the potential to harbor alien life. The planet, known as Ross 128 b, is located a mere 11 light-years from Earth, and will one day become the closest exoplanet to our Sun, dethroning our current immediate neighbor exoplanet – Proxima b...Continue Reading Temperate Earth-sized exoplanet discovered only 11 l
An international team of astronomers has discovered a massive Jupiter-sized planet orbiting an M-dwarf star only half the mass and size of our Sun. The existence of so massive a planet around such a small star challenges current theories regarding planetary formation...Continue Reading Massive exoplanet discovery challenges theories on planetary formationCategory: SpaceTags: ESO
A team of astronomers may have discovered a "hot Jupiter" exoplanet with an atmosphere that snows titanium oxide – a kind of sunscreen – exclusively on the one side of the planet that is bathed in perpetual darkness. The study, which definitively proves that the universe has a great sense of humor, could one day be used to inform astronomers trying to judge the habitability of atmosphere-host
