Radiation bombardment from Jupiter makes Europa glow in the dark

Giving a new meaning to the word “moonshine,” NASA scientists at the Jet Propulsion Laboratory (JPL) in Pasadena, California, have concluded that Jupiter’s moon Europa glows in the dark due to being constantly bombarded with high-energy radiation.Conti… Continue reading Radiation bombardment from Jupiter makes Europa glow in the dark

Sprites and elves spotted lighting up Jupiter’s atmosphere

Atmospheric phenomena known as “sprites” and “elves” may be spectacularly illuminating the upper cloud layers of Jupiter, according to a newly published study based on data collected by NASA’s Juno spacecraft. These short-lived light displays have been… Continue reading Sprites and elves spotted lighting up Jupiter’s atmosphere

Hubble’s stunning new snaps of Jupiter reveal fresh storms brewing

It’s human nature to be transfixed by clouds and all the strange shapes they swirl into, but we don’t have to be limited to Earthly skies. Jupiter offers some of the best cloud-watching in the solar system, and new Hubble images remind us why, revealin… Continue reading Hubble’s stunning new snaps of Jupiter reveal fresh storms brewing

Mysterious match-up as giant planet spotted orbiting tiny star

NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered a strange star system, where a giant gassy planet is tightly orbiting a tiny white dwarf. Not only is this the first time such an arrangement has been seen, but it raises some very odd … Continue reading Mysterious match-up as giant planet spotted orbiting tiny star

How gravitational tides help explain the puzzle of Jupiter’s hot moons

A new study from the University of Arizona indicates that Jupiter’s four largest moons are as warm as they are thanks to tidal forces caused by the moons’ gravitational fields tugging on one another. This tidal heating may help to explain how the Jovia… Continue reading How gravitational tides help explain the puzzle of Jupiter’s hot moons

Strange lightning and “mushball” rain could rage in Jupiter storms

With storms constantly raging all over its surface and a Great Red Spot that’s been churning for centuries, Jupiter could be known as the storm capital of the solar system. Now NASA’s Juno mission has discovered two new quirks of these storms – shallow… Continue reading Strange lightning and “mushball” rain could rage in Jupiter storms

Juno Jupiter probe finds glass-like ice on Ganymede’s north pole

NASA has released the first images taken by its Juno deep-space probe of the north pole of Jupiter’s largest moon, Ganymede. Captured on December 26, 2019, the infrared images from the spacecraft’s Jovian Infrared Auroral Mapper (JIRAM) instrument show… Continue reading Juno Jupiter probe finds glass-like ice on Ganymede’s north pole

Exposed core of ancient gas giant discovered orbiting Sun-like star

Astronomers have discovered the intact, exposed core of a gas giant locked in a close orbit around a Sun-like star. The discovery will give astronomers a rare opportunity to probe the heart of an ancient alien world, and their findings could tell us mo… Continue reading Exposed core of ancient gas giant discovered orbiting Sun-like star
