A "Jupiter" hotter than the sun
The search for exoplanets—planets that orbit stars located beyond the borders of our solar system—is a hot topic in astrophysics. Of the various types of exoplanets, one is hot in the literal sense: hot Jupiters, a class of exoplanets that are ph.....»»
NASA"s Hubble Spots a Heavy Metal Jupiter Where It Rains Liquid Gems
An anonymous reader shares a report: The exoplanet WASP-121b, which resides about 900 light-years from Earth, is an egg-shaped scorcher. Temperatures on the planet's day side can reach up to 4,600 degrees Fahrenheit. It's so hot that heavy metal elem.....»»
Jupiter, Saturn, Uranus, Neptune: Why our next visit to the giant planets will be so important, and just as difficult

Exploring oxygen ions in Jupiter"s innermost radiation belts
Planets like Earth, Jupiter and Saturn, with global magnetic fields of their own, are surrounded by so-called radiation belts: Trapped in the magnetic field, fast moving charged particles such as electrons, protons, and heavier ions whiz aroun, thus.....»»
Accumulated heat in the upper ocean is at record levels again
The world's oceans are hotter than ever before, continuing their record-breaking temperature streak for the sixth straight year. The finding based on the latest data through 2021 comes at the end of the first year of the United Nations' Decade of Oce.....»»
New sub-Jupiter-mass exoplanet detected by astronomers
An international team of astronomers reports the detection of a new sub-Jupiter-mass alien world orbiting an M-dwarf star. The newly found exoplanet, designated OGLE-2014-BLG-0319Lb, turns out to be about half as massive as Jupiter. The discovery was.....»»
Earth’s Oceanography Helps Demystify Jupiter’s Flowing Cyclones
A team of scientists shows where some of the gas giant’s huge storms come from and how the process is similar to the buildup of extreme weather on our planet......»»
Drought makes heatwaves hotter but less deadly
During heatwaves, the land dries out. That drought further enhances the rising of heatwave temperatures. However, desiccated soils still make the heatwaves less rather than more deadly to humans, due to a reduction in air humidity......»»
Ocean physics explain cyclones on Jupiter
Hurtling around Jupiter and its 79 moons is the Juno spacecraft, a NASA-funded satellite that sends images from the largest planet in our solar system back to researchers on Earth. These photographs have given oceanographers the raw materials for a n.....»»
Jupiter"s Moons Are About To Get JUICE"d For Signs of Life
The European Space Agency will soon send JUICE, or the JUpiter ICy moons Explorer on a mission to scout out Jupiter and three of its 79 moons: Europa, Callisto, and Ganymede. From a report: Scheduled to launch in April 2023, JUICE will blast off from.....»»
