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

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 ...

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 ...

New research suggests that Jupiter, the largest planet in our solar system, was once even bigger—about twice its current size—and had a magnetic field 50 times stronger than it does today. This ...

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 ...

The Space Telescope Science Institute in Baltimore, which operates the Webb and Hubble telescopes, released a video of Jupiter's tempestuous roiling auroras, which you can watch above.

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 ...
