“Hot Jupiters” aren’t particularly sexy exoplanets—just clingy ones. These gas giants orbit tightly around their host stars, and despite their name, they’re typically more massive than Jupiter. And, as you’d expect, much hotter.
Astronomers have discovered a newly born “hot Jupiter” in a distant star system that’s locked in a slow death spiral. It may only be a matter of time before this poor baby planet gets torn to shreds.
Astronomers from Wesleyan University have detected the shock waves produced by a high-speed “hot Jupiter” exoplanet caught in a tight orbit around its host star. It’s a potential indication of an incredibly powerful magnetic field around the planet.
Behold the lightest planet ever imaged by a telescope: an extremely young, Jovian-like planet that’s twice the size of Jupiter. Astronomers detected it through visible light, which is an extraordinary feat for a planet of this nature.
Astronomers watching a small red dwarf star 500 light years away were surprised to notice a brief dip in its already dim light. But they quickly identified the source of the change: the darker mass of a planet passing between the distant star and our vantage point on Earth.
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.
There's a gas giant located about 330 light-years from here that's not only unusually large, it's also orbiting its host star at an incredibly close distance. According to a new study, this combination of factors is wreaking havoc on the star's innards.
New research shows that star-snuggling hot Jupiters, despite being only a thousandth of the mass of their host suns, make their host stars wobble like a spinning top.
Prior to the discovery of exoplanets, astronomers assumed that our solar system's configuration was typical. But now, some 1,715 exoplanets later, we know that we're far from ordinary. So what passes for "normal" in the annals of solar systems? Here's what we know now.
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.
An emerging branch of science known as exometeorology is offering remarkable insights into the conditions found on some of the more extreme planets in the galaxy — including the weird and mind-boggingly massive weather patterns experienced on a hot Jupiter that's 385 light years from Earth.
