What will Europe's Jupiter Icy Moon Explorer (JUICE) tell us about the presence of life in the vicinity of the solar system's largest planet?

Europe's Jupiter Icy Moons Explorer (JUICE) is setting out for an ambitious tour of Jupiter's moons. But it will only take a brief glimpse of the potentially life-harboring Europa. Here's why.

A powerful solar flare knocked out radio communications on Earth last night in what space weather forecasters fear might be the beginning of a spell of rough space weather in the coming days.

The brightest gamma-ray burst ever seen blinded all of NASA's flagship gamma-ray missions last year. This tiny Eastern European cubesat, however, didn't get overwhelmed.

The atmospheres of gas giant planets across the Milky Way galaxy can be very different from those in the solar system, the James Webb Space Telescope has found.

A huge amount of water may be trapped in beads of glass strewn across the moon's surface, an analysis of lunar soil samples delivered by China's Chang'e-5 probe revealed.

New measurements by the James Webb Space Telescope found that a rocky exoplanet orbiting a star known as TRAPPIST-1 most likely has no atmosphere.

New images of Uranus and Jupiter taken by the Hubble Space Telescopes reveal slow weather changes on these giant, distant planets.

A surprise solar storm supercharged auroras across the U.S. and Europe last night (March 23), with sightings of the colorful displays reported from as far south as New Mexico and Arizona.

The strongest solar storm in six years delayed Rocket Lab's early morning launch on Friday, March 24, by 90 minutes, and space weather forecasters didn't see coming.

These weather disasters provide a glimpse of lies ahead for planet Earth if humankind fails to stop climate change progress.

Since its arrival in the solar system in 2017, interstellar object 'Oumuamua has puzzled scientists. Two American astronomers now think they have solved one of the space rock's biggest mysteries.

First hibernation studies with human subjects could be feasible within a decade, a European Space Agency (ESA) researcher thinks.

NASA's Solar Dynamics Observatory captured what might be 'the tallest tornado' in the solar system swirling across the north pole of the sun.

For the first time, a space-born smog sensor will be able to provide data on the distribution of air pollutants over America non-stop and in real time.

Europe's first Jupiter-bound mission is in the final stages of preparations for its launch on April 13 from the European spaceport in Kourou, French Guiana.

Forms of oxygen created by living organisms can be found in space around our planet, a new study has revealed, hinting at a potential new method for tracing life on exoplanets.

Antarctic sea ice shrunk to a record low in February, satellite measurements revealed.

The powerful solar storm that struck Earth earlier this week treated an American astrophotographer to unexpected aurora displays during a shooting trip to California's Death Valley.

A series of powerful solar storms set the sky ablaze in the last two days of February, with aurora sightings reported unexpectedly far away from their usual territories.
