Weather can get pretty rough here on Earth, but there’s a rocky exoplanet located about 40 light-years away that features some of the most extreme temperature fluctuations ever seen by astronomers—reaching temperatures so high that lava flows directly on the surface.
A gas giant located about 260 light-years from here has winds that howl at the speed of sound and a day side that's hot enough to melt iron. We know this because astronomers have just made the most detailed weather map of the temperature of an exoplanet's atmosphere. Here's the forecast for WASP-43b.
They’re big, full of gas, and have a penchant for hanging out way too close to their parents. These “hot Jupiters” are among the most common extrasolar planets in the galaxy. Here’s what the latest science is telling us about these celestial wonders.
