In April, scientists announced that they had used NASA’s James Webb Space Telescope to find a potential signature of alien life in the glow of a distant planet. Other scientists were quick to ...

THE James Webb Space Telescope has discovered its first-ever exoplanet – a distant world hidden by the glare of its nearest ...

When the Sun becomes a red giant, will the outer planets and moons become more temperate and conducive to ... but we now know of quite a few examples of hot Jupiters - gas giants tightly orbiting ...

New James Webb Space Telescope data reveal Pluto's high-altitude haze is a key driver of the climate on the dwarf planet, ...

The Voyager 1 spacecraft had flown past this moon of Jupiter, catching the first glimpse of active volcanism on a world other than Earth. Umbrella-shaped outbursts of magmatic matter rocketed into ...

But a team of scientists has created a new way to answer whether aliens exist. Daniel Apai, an astrophysicist and astrobiologist at the University of Arizona, studies exoplanets – worlds that orbit ...

Jupiter's ice-covered moon Europa will get a lot of heat. Not only will the giant sun be bearing down on it, but Jupiter itself will become hotter and reflect more sunlight, which will provide its ...

Jupiter's strong gravity field constantly tugs on Europa as it orbits its parent planet every three-and-a-half days, squeezing and flexing the moon's insides and generating heat through tidal forces.

Based on precise analysis of Europa's movements orbiting Jupiter, scientists believe an ocean is present under the moon's icy crust that may provide a habitable environment. / Credit: NASA More ...

NASA’s Europa Clipper spacecraft — designed to explore its namesake, Jupiter’s moon Europa — launched aboard a SpaceX Falcon Heavy rocket Monday at 12:06 p.m. ET from NASA’s Kennedy ...

If all goes well, the probe will brake into orbit around Jupiter on April 11, 2030, using the gravity of the moon Ganymede to slow down before a six- to seven-hour firing of the probe's thrusters.

One of Jupiter’s 95 known moons, Europa is almost the size of our own moon. It's encased in an ice sheet estimated to be 10 miles to 15 miles or more thick. Scientists believe this frozen crust ...
