The new calculations, described in a paper published Tuesday (May 20) in the journal Nature Astronomy, suggest that just 3.8 ...

The researchers also determined that Jupiter's magnetic field at that time was approximately 50 times stronger than it is today. Adams highlights the remarkable imprint the past has left on today ...

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.

To better understand Jupiter’s primordial stages, researchers turned to the tiniest of the planet’s 92 known moons. Almathea and Thebe respectively circle Jupiter at slightly tilted orbits roughly 112 ...

Research reveals Jupiter was larger with a stronger magnetic field early on. Jupiter's primordial size was about twice its current radius, say researchers. Clues from 4.5 billion years ago help ...

New data from Webb is challenging previous assumptions about Jupiter's auroras, its magnetic field and particle interactions. If you thought the flickering green and red auroras of Earth were ...

"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 ...
