Meteoric Ions Influence Conductance in the Jovian Ionosphere

by Viviane Pierrard 29 April 202225 April 2022

Meteoric ions dominate the Jovian lower ionosphere due to their long lifetimes. Due to the large densities of the meteoric ions, conductance is enhanced independently of local time.

A Transition Zone Below Jupiter’s Clouds

by Morgan Rehnberg 12 November 202127 January 2022

The microwave radiometer aboard NASA’s Juno spacecraft reveals the hidden atmospheric circulations at work deep below Jupiter’s colorful clouds.

Could Low-Altitude Reconnection Power Jupiter’s Polar Aurorae?

by Morgan Rehnberg 21 September 202127 January 2022

Magnetic reconnection events less than 2 Jovian radii above the planet’s cloud tops could explain why Juno has yet to observe a source for Jupiter’s polar aurore.

A new population of highly energetic ions has been discovered at midlatitudes within the inner edge of Jupiter’s relativistic electron belt.

Juno Detects Jupiter’s Highest-Energy Ions

by Morgan Rehnberg 17 June 202127 January 2022

Trapped ions discovered at midlatitudes can have energies exceeding 100 megaelectron volts per nucleon. Their detection adds to our understanding of the powerful radiation environment around Jupiter.

Fingerprints of Jupiter Formation

by B. Ehlmann 16 June 202127 January 2022

Meteorite isotopes, meteorite paleomagnetics, and planet formation models collectively show Jupiter formation via first slow then fast collection of material by core accretion in <5 million years.

Dawn Storms at Jupiter

by M. Hudson 16 March 202127 January 2022

Juno spacecraft observations provide the first global description of dawn storms in Jupiter’s aurorae, from their initiation to their end.

Radio on Jupiter, Brought to You by Ganymede

by A. Yau 25 January 202127 January 2022

Another first from NASA’s Juno spacecraft: the detection of Jupiter radio emissions influenced by the moon Ganymede, over a range of about 250 kilometers in the polar region of Jupiter.

Juno Maps Water Ice Across Northern Ganymede

by Morgan Rehnberg 14 January 2021

Infrared observations from instruments on the Juno spacecraft cover regions of Ganymede not visible to Earth-based telescopes.

A Whistle Here, There, and Everywhere on the Giant Planet

by A. Yau 27 August 202010 March 2022

NASA’s Juno spacecraft is “hearing whistles” all over the place on Jupiter, a type of natural plasma waves called whistlers that are sometimes associated with atmospheric lightning.

Jupiter’s Ocean Moons Raise Tidal Waves on One Another

by Rachel Fritts 20 August 202027 January 2022

New research considers the effect of Jupiter’s Galilean moons on each other’s oceans for the first time.
