Despite being very much not like our Earth, large gas giant planets found very close to their stars have proven to be ideal test targets for telescopes like the James Webb Space Telescope (JWST) to refine astronomers’ methods of understanding exoplanets.</p> Fri, 05 Jan 2024 16:47:02 +0000 claire.loewen@mcgill.ca 307572 at /newsroom /newsroom/channels/news/hot-jupiter-unusual-winds-284028 <p>The hottest point on a gaseous planet near a distant star isn’t where astrophysicists expected it to be – a discovery that challenges scientists’ understanding of the many planets of this type found in solar systems outside our own.</p> <p><span>Unlike our familiar planet Jupiter, so-called hot Jupiters circle astonishingly close to their host star -- so close that it typically takes fewer than three days to complete an orbit.  And one hemisphere of these planets always faces its host star, while the other faces permanently out into the dark.</span></p> Fri, 19 Jan 2018 21:53:02 +0000 christopher.chipello@mcgill.ca 32859 at /newsroom /newsroom/channels/news/nasas-hubble-captures-blistering-pitch-black-planet-270306 <p>NASA's Hubble Space Telescope has observed a planet outside our solar system that looks as black as fresh asphalt because it eats light rather than reflecting it back into space. This light-eating prowess is due to the planet's unique capability to trap at least 94 percent of the visible starlight falling into its atmosphere.</p> Thu, 14 Sep 2017 15:13:06 +0000 justin.dupuis@mcgill.ca 32288 at /newsroom /newsroom/channels/news/expert-nasa-news-conference-exoplanet-feb-22-2017-266556 <p>NASA will hold a news conference at 1 p.m. EST Wednesday, Feb. 22, to present new findings on planets that orbit stars other than our sun, known as exoplanets.
