Jupiter is already the biggest planet by far in our solar system, but new research suggests it was somehow once even larger than it is now. Twice as large, in fact. To put that into context, those ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. Jupiter's radius used to be twice its current size, and the planet had a magnetic field 50 times ...

Astrophysicists found an exoplanet the size of Jupiter has a tail of gas seven times its own length—around 350,000 miles—resulting from its gas atmosphere burning off and being shaped by stellar winds ...

The bright star seen in the eastern evening sky in recent weeks isn't a star, it's a planet. Jupiter is at its closest (380,161,047 miles away by my math), and as a result, biggest and brightest this ...

The Webb Space Telescope spotted a gas giant roughly the same diameter as Jupiter, but with six times the mass, orbiting a neighboring star, Epsilon Indi A. It might take this planet as long as 250 ...

CAPE CANAVERAL, Fla. — A super Jupiter has been spotted around a neighboring star by the Webb Space Telescope — and it has a super orbit. The planet is roughly the same diameter as Jupiter, but with ...

"We detected another planet even closer to the star that interacts strongly with its big neighbor, causing their orbits to wobble in ways we've never seen before." When you purchase through links on ...

It’s like something out of an interplanetary chess game. Astrophysicists at the University of Toronto have found that a close encounter with Jupiter about four billion years ago may have resulted in ...

Astrophysicists have found that a large exoplanet known as WASP-69b is being trailed by a tail of gas seven times as long as the planet itself. The comet-like tail is the result of the planet’s gas ...

As Earth catches up to and passes Jupiter bringing it at its closest, biggest, and brightest in the evening sky. The bright star seen in the eastern evening sky in recent weeks isn't a star, it's a ...
