Hot Jupiters, the blisteringly close cousins of our own Jupiter, were once treated as cosmic misfits. Now their orbital patterns are turning into a kind of forensic record, revealing how these giants ...

An eye-catching pattern on the surface of Europa, an ice-covered moon, may have profound implications for our understanding ...

There is more than meets the eye for a distant gas giant planet. Astronomers have discovered that the extrasolar planet, or "exoplanet," not only has one of the weirdest orbits ever seen, but it is ...

Earth, and every other planet within our Solar System that we know of, orbits the Sun. Beyond our small region of the universe, planets everywhere orbit their stars. Even tiny changes in these orbits ...

Credit: NASA, ESA, CSA, Jupiter ERS Team; Image Processing by Judy Schmidt. Oh, Jupiter. If only the gas giant shifted its orbit slightly, becoming more eccentric (read: oval-shaped), it could ...

Just recently on the blog I posted a series of images of Jupiter taken by JWST, some of which showed Jupiter’s faint ring. I don’t think a lot of people know that all four giant planets in our solar ...

Scientists have confirmed the existence of an "extraordinary" hot Jupiter-type planet that may help explain how the gas giants of our own solar system were formed. The planet, named Kepler-1704b, ...

A four-decade-long study documenting temperatures in Jupiter’s atmosphere using NASA spacecraft has revealed unexpected behavior in the gas giant’s weather over time. NASA says the study is the ...

The JunoCam camera aboard NASA’s Juno mission is operational and sending down data after the spacecraft’s July 4 arrival at Jupiter. Juno’s visible-light camera was turned on six days after Juno fired ...

The first planet ever found orbiting another star was detected in 1995, and it belonged to a class now known as a “hot Jupiter.” These exoplanets are comparable in mass to Jupiter but circle their ...
