NASA has switched off another scientific instrument on its Voyager 2 spacecraft to save power. The space agency said Tuesday the instrument that measures the flow of charged atoms was powered down so Voyager can keep exploring for as long as possible.

NASA's Voyager 1 and 2 spacecraft have traveled further away from Earth than any other human-made object, sending back useful science data from the edge of the Solar System. But now, having spent 47 years in space,

The mission has been working to postpone the shut-off as long as possible. Four other instruments aboard the interstellar spacecraft continue to operate.

Thunderstorms create a lot of wind, rain, and lightning, but many people aren’t necessarily aware of another common byproduct: gamma radiation. Thanks to a creative retrofit of an old U-2 spy plane courtesy of NASA,

Most tropical lightning storms are RADIOACTIVE, reveals new research. Observations from a retrofitted U2 American spy plane found a "surprising" amount and variety of gamma radiation is produced in large tropical thunderstorms.

Although researchers have long known that thunderstorms generated high-energy particles otherwise detected in supernovae,

Juice (Jupiter Icy Moons Explorer) mission made history with a daring lunar-Earth flyby and double gravity assist maneuver, a spaceflight first. As the spacecraft zipped past our moon and home planet,

NASA’s JUICE spacecraft (Jupiter Icy Moons Explorer) has captured the most detailed image yet of Earth’s radiation belts during a recent flyby of the Moon and Earth. This breakthrough marks a new milestone in the mission,

The Jupiter Icy Moons Explorer (JUICE) mission run by the European Space Agency (ESA) has taken the sharpest images ever produced of the Earth's radiation belt. JUICE has a long mission ahead of it. Launched in April 2023,
