Jupiter may have been struck by a huge protoplanet long ago, spreading the heavy material inside the planet's core across a much wider area inside the planet than we'd typically expect to find ...

Jupiter is not only the largest in the solar system, but is so humongous that it's more than twice as massive as the other planets combined. The gas giant is about 11 times wider than Earth alone ...

When Jupiter formed 4.5 billion years ago, rocks and ice combined to form a rocky core 14-18 times the mass of the Earth, according to a new simulation by UC Berkeley geophysicist Burkhard Militzer.

Why it matters — The measurements Juno has taken of Jupiter’s core reflect the kinds of pressures and temperatures that could only come close to being recreated on Earth if you were studying ...

Jupiter may have eaten so much nebula when it \nwas forming that it now has a case of cosmic \nheartburn. New computer models suggest that \nit's inner core may be dissolving and bubbling \nup to ...
