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.

Jupiter, roughly 562 million miles from Earth today, has nearly 100 moons. But Batygin and his collaborator Fred Adams' research focused on two of the smaller ones, Amalthea and Thebe. Both are inside ...

What if Earth suddenly expanded to be as massive and large as Jupiter, the gas giant? This hypothetical scenario would lead to extraordinary changes in our planet’s environment, structure, and life ...

With an atmosphere, by mass, of primarily hydrogen (76 per cent) and helium (24 per cent), and by volume of 89 per cent ...

Astronomers have calculated that the gas giant Jupiter used to be twice as big as it is now, based on the odd orbits of two ...

ESA’s Jupiter Icy Moons Explorer (JUICE) that was launched in 2023 will take about 8 years to arrive at the jovian system after several gravity assists. Credit: Space.com | animation courtesy: ESA / A ...

Jupiter wasn’t always the planet we know today—it was once twice as big, had a magnetic field 50 times stronger, and its ...

Scientists focused on Jupiter's little moons Amalthea and Thebe. Their peculiar orbits didn't quite fit with Jupiter's ...

Jupiter may have once been more than twice its current size, with a magnetic field 50 times stronger, say scientists who ...

"It's astonishing that even after 4.5 billion years, enough clues remain to let us reconstruct Jupiter's physical state at the dawn of its existence," stated Fred C. Adams, professor of physics and ...

Many scientists refer to Jupiter as the "architect" of the solar system because its immense gravity influenced the orbits of other planets and carved up the cloud from which they all emerged.

Simulations show that the stars’ tug could send Mercury, Venus or Mars crashing into Earth — or let Jupiter eject our world from the solar system.
