Laboratory experiments allow insights into the processes under the extreme pressure and temperature conditions of distant worlds.

Although patterns in the timing of moderate space weather events are known, the most extreme and dangerous events were thought to be random in their timing. This study found for the first time that extreme space weather occurs most frequently at predictable times during solar cycles, meaning space missions could be timed to avoid them.

Supermassive black holes devour stellar material just like their more petite counterparts, a new study finds.

NASA's Voyager I spacecraft has long since zipped past the edge of the solar system through the heliopause - the solar system's border with interstellar space - into the interstellar medium. Now, its instruments have detected the constant drone of interstellar gas (plasma waves).

The famed northern and southern lights have been studied for millennia, but they still hold secrets. Physicists describe a new phenomenon they call 'diffuse auroral erasers,' in which patches of the background glow are blotted out, then suddenly intensify and reappear.

New simulations offer an intriguing look into Saturn's interior, suggesting that a thick layer of helium rain influences the planet's magnetic field.

A new map of the Schrodinger basin of the moon could help guide future exploration missions.

NASA's Hubble Space Telescope is giving astronomers a rare look at a Jupiter-sized, still-forming planet that is feeding off material surrounding a young star.

Researchers are now measuring tinier moon dust particles than ever before, a step toward more precisely explaining the Moon's apparent color and brightness. This in turn might help improve tracking of weather patterns and other phenomena by satellite cameras that use the Moon as a calibration source.

Scientists detect small pockets of carbon dioxide-rich liquid water in a meteorite dating from the early solar system.

On May 1, 2019, researchers observed a record-setting flare from the star Proxima Centauri -- a burst of energy roughly 100 times more powerful than any similar event seen from Earth's sun.

Jupiter's polar cap is threaded in part with closed magnetic field lines rather than entirely with open magnetic field lines, new research finds.

A new study shows a correlation between the end of solar cycles and a switch from El Nino to La Nina conditions in the Pacific Ocean, suggesting that solar variability can drive seasonal weather variability on Earth.

Astronomers have detected X-rays from Uranus using NASA's Chandra X-ray Observatory. This result may help scientists learn more about this enigmatic ice giant planet in our solar system.

Astronomers have detected new faint aurora features, characterized by ring-like emissions, which expand rapidly over time. Scientists determined that charged particles coming from the edge of Jupiter's massive magnetosphere triggered these auroral emissions.

New research could inform where to one day search for signs of life on Saturn's moon Enceladus.

Sun-facing satellites monitor the Sun's ultraviolet (UV) light to give us advance warning of solar storms. But over the course of just a year or two, the metal filters in the detectors mysteriously lose their ability to transmit UV light. Now, scientists have found the first evidence indicating that carbonization is not the problem.

Astronomers have now directly measured winds in Jupiter's middle atmosphere. By analyzing the aftermath of a comet collision from the 1990s, the researchers have revealed incredibly powerful winds, with speeds of up to 1450 kilometers an hour, near Jupiter's poles. They could represent a 'unique meteorological beast in our Solar System'.

The stormy, centuries-old maelstrom of Jupiter's Great Red Spot was shaken but not destroyed by a series of anticyclones that crashed into it over the past few years, according to a new study.

The midnight births of the dramatic bright surges in Jupiter's aurora known as dawn storms are captured in a new study of data from the Juno space probe.
