In its earliest days, Jupiter may have been even more colossal than it is now—twice as large, in fact, with a magnetic field ...

Using computer simulations, the researchers uncovered a scenario in which an ancient asteroid impact briefly amplified that field, just long enough for nearby rocks to capture and record its magnetic ...

NASA’s Lunar Reconnaissance Orbiter (LRO) has been mapping the Moon since 2009, helping identify important scientific sites ...

Discoveries from NASA's GRAIL mission reveal the moon's uneven interior, with a molten layer beneath the near side surface.

Scientists may have solved the mystery of why the moon shows ancient signs of magnetism although it has no magnetic field today. An impact, such as from a large asteroid, could have generated a cloud ...

A recent study found that Jupiter was once twice the size that it is now, making it big enough to swallow up 2,000 Earths.

While the moon once had a weak magnetic field generated by a small molten core, the team's research suggests it likely wouldn ...

Where did the moon's magnetism go? Scientists have puzzled over this question for decades, ever since orbiting spacecraft ...

Discover interesting facts about how the moon formed, what it's made out of, and the many missions humans have launched to ...

There have been proposed hypotheses as to how the Moon could have developed a core dynamo. For instance, a 2022 analysis ...

Titan, Saturn’s largest moon, has always fascinated scientists with its thick, hazy atmosphere—the only one like it on any ...

Naturally, the aurora on our solar system's largest planet is hundreds of times brighter and more energetic than our own Northern lights.
