According to scientists from Æ»¹ûÒùÔº, York University, and the Indian Institute of Science Education, the atmosphere and weather cycle of at least one such exoplanet is even stranger, featuring the evaporation and precipitation of rocks, supersonic winds that rage over 5000 km/hr, and a magma ocean 100 km deep.</p> Wed, 04 Nov 2020 00:01:15 +0000 webfull 164883 at /channels /channels/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> Mon, 22 Jan 2018 16:08:46 +0000 webfull 134293 at /channels /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.
