Search results for exoplanet

According to simulations and models, exoplanet sizes should be spread out relatively evenly. But with the exoplanet tally approaching 4,000, that hasn't really been the case. A type of world dubbed a "hot Neptune" has been conspicuously few and far between, but a new observation may explain why. Hubble has now spotted a hot Neptune named GJ 3470b that's vanishing at a record rate... Contin
An international team of astronomers has discovered that helium atoms are causing the atmosphere of a "warm-Neptune" exoplanet to expand like a party balloon before escaping into the cold expanse of space. The discovery could help scientists understand the extreme processes taking place in the atmospheres of the hottest exoplanets discovered to date... Continue Reading Warm Neptune exoplan
Astronomers have discovered a "super-Earth" located just six light-years from our planet, orbiting the nearest lone star to our Sun. Named for its parent star, the exoplanet Barnard's Star b has a mass roughly 3.2 times that of the Earth, and a frigid surface temperature of -170 °C (-274 °F), making it an unlikely prospect in the search for extraterrestrial life...

Following a successful journey to lunar resonant orbit (with a couple of holiday snaps along the way), NASA's Transiting Exoplanet Survey Satellite (TESS) is now getting down to business. The agency today shared the first science image captured by the space telescope, providing researchers with plenty of inspiration in their search for other worlds that might resemble our own...

Having won the Small Satellite Mission of the Year award, the Arcsecond Space Telescope Enabling Research in Astrophysics (ASTERIA) satellite has put the icing on the cake by claiming the first exoplanet to be detected by a CubeSat. About the size of a briefcase, the miniature spacecraft was able to accurately measure the transit light curve of the already known super-Earth exoplanet 55 Ca
It takes some serious heat to turn titanium into vapor – temperatures upward of 3,200 °C (5,800 °CF), to be precise. It appears KELT-9b, which we crowned the exoplanet Least Likely To Host Life last year, is up for the job. Its broiling surface temperatures make it hotter than many stars – and, according to a new discovery, hot enough to vaporize heavy metals, with researchers detecting ir
NASA's Transiting Exoplanet Survey Satellite (TESS) did a bit of limbering up before commencing its science operations on July 25, 2018. As a part of last-minute tests before starting its search for exoplanets on that day, the unmanned space telescope demonstrated what it could do by snapping a series of images capturing the motion of a comet over the course of 17 hours...

NASA's next-generation exoplanet hunter began its science mission this week. On July 25, the unmanned Transiting Exoplanet Survey Satellite (TESS) got to work on its two-year whole-sky survey to seek out planets outside our solar system by looking at the nearest and brightest stars for signs of changes in their brightness, indicating that a planet or other orbiting body is passing in front
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 is a social bookmarking place where you can share, find & discuss the best news around on most topics.
