An icy ocean world in our solar system that could tell us more about the potential for life on other worlds is coming into focus with confirmation of the Europa Clipper mission's next phase.


A Young Jupiter Was Smacked Head-on By A Massive Newborn Planet

A Young Jupiter Was Smacked Head-on By A Massive Newborn Planet

A colossal, head-on collision between Jupiter and a still-forming planet in the early solar system, about 4.5 billion years ago, could explain surprising readings from NASA's Juno spacecraft, according to a study this week in the journal Nature.

The NASA/ESA Hubble Space Telescope reveals the intricate, detailed beauty of Jupiter's clouds in this new image taken on 27 June 2019.


Juno Finds Changes in Jupiter's Magnetic Field

Juno Finds Changes in Jupiter's Magnetic Field

NASA's Juno mission to Jupiter made the first definitive detection beyond our world of an internal magnetic field that changes over time, a phenomenon called secular variation. Juno determined the gas giant's secular variation is most likely driven by the planet's deep atmospheric winds.


Jupiter's Atmosphere Heats Up Under The Solar Wind

Jupiter's Atmosphere Heats Up Under The Solar Wind

New Earth-based telescope observations show that auroras at Jupiter's poles are heating the planet's atmosphere to a greater depth than previously thought -- and that it is a rapid response to the solar wind.


Jupiter's Great Red Spot

Jupiter's Great Red Spot

This striking view of Jupiter's Great Red Spot and turbulent southern hemisphere was captured by NASA's Juno spacecraft as it performed a close pass of the gas giant planet.
