Jovian planets, after Jupiter, are also called giant planets or gas giants. However, many astronomers apply the latter term only to Jupiter and Saturn, classifying Uranus and Neptune, which have different compositions, as ice giants. Both names are potentially misleading: all of the giant planets consist primarily of fluids above their critical points, where distinct gas and liquid phases do not exist. The principal components are hydrogen and helium in the case of Jupiter and Saturn, and water, ammonia and methane in the case of Uranus and Neptune. Many extrasolar giant planets have also been identified orbiting other stars. — Wikipedia
Ring system is a disc or ring orbiting an astronomical object that is composed of solid material such as dust and moonlets, and is a common component of satellite systems around giant planets. A ring system around a planet is also known as a planetary ring system.
The most prominent and most famous planetary rings in the Solar System are those around Saturn, but the other three giant planets (Jupiter, Uranus, and Neptune) also have ring systems. Recent evidence suggests that ring systems may also be found around other types of astronomical objects, including minor planets, moons, and brown dwarfs. — Wikipedia

Undersea gases could superheat the planet
on February 13, 2019 at 2:48 pm
The world's oceans could harbor an unpleasant surprise for global warming, based on new research that shows how naturally occurring carbon gases trapped in reservoirs atop the seafloor escaped to superheat the planet in prehistory. […]
Kepler's final image
on February 12, 2019 at 1:25 pm
On October 30th, 2018, after nine years of faithful service, the Kepler Space Telescope was officially retired. With nearly 4000 candidates and 2,662 confirmed exoplanets to its credit, no other telescope has managed to teach us more about the worlds that exist beyond our solar system. In the coming years, multiple next-generation telescopes will be deployed that will attempt to build on the foundation Kepler built. […]

Extreme cold weather can produce unusual phenomena, from so-called sea smoke to slushy ocean waves. As atmospheric scientist Scott Denning explains, these striking events are caused mainly by the behavior of water at very cold temperatures. […]
