Oct 29, 2021 (SPX)
Researchers published several papers on Juno's atmospheric discoveries in the journal Science and the Journal of Geophysical Research: Planets. Additional paper...
Using Charon-light Researchers Capture Pluto's Dark Side
Oct 28, 2021 (SPX)
After flying within 7,800 miles (12,550 kilometers) of Pluto's icy surface on July 14, 2015, New Horizons continued at a rapid 9 miles per second (14.5 kilomete...
Jupiter's Great Red Spot is deeper than thought, shaped like lens
Oct 28, 2021 (UPI)
The vortex storm, the largest of many such spots on Jupiter's surface, extends up to 310 miles below the planet's cloud tops, some 100 miles deeper than previou...
Keeping our eyes on New Horizons
Oct 25, 2021 (SPX)

The unusual magnetic fields of Uranus and Neptune
Oct 18, 2021 (SPX)
However, the exact conditions at which superionic ices are stable remain controversial. A team of scientists led by Vitali Prakapenka from the University of Chi...
SwRI scientists confirm decrease in Pluto's atmospheric density
Oct 05, 2021 (SPX)
The occultation took about two minutes, during which time the star faded from view as Pluto's atmosphere and solid body passed in front of it. The rate at which...
Come on in, the water is superionic
Sep 24, 2021 (SPX)
Superionic water is a phase of H2O where hydrogen atoms become liquid-like while oxygen atoms remain solid-like on a crystalline lattice. Although superionic wa...
Mushballs stash away missing ammonia at Uranus and Neptune
Sep 20, 2021 (SPX)
Recently, remote observations at infrared and radio wavelengths have shown that Uranus and Neptune lack ammonia in their atmosphere compared to the other giant ...
Uranus to begin reversing path across the night sky on Wednesday
Aug 24, 2021 (UPI)
Retrograde motion occurs as the Earth moves around the sun and the stellar views at night change little by little. The orbit, in turn, makes objects like planet...
A few steps closer to Europa: spacecraft hardware makes headway
Aug 06, 2021 (JPL)
The massive 10-foot-tall (3-meter-tall) propulsion module recently moved from NASA's Goddard Space Flight Center in Greenbelt, Maryland, to the Johns Hopkins Ap...
Juno joins Japan's Hisaki satellite and Keck Observatory to solve energy crisis on Jupiter
Aug 05, 2021 (SPX)

Surface of Jupiter's moon Europa churned by small impacts
Jul 14, 2021 (JPL)
NASA-funded scientists are studying the cumulative effects of small impacts on Europa's surface as they prepare to explore the distant moon with the Europa Clip...
The mystery of what causes Jupiter's X-ray auroras is solved
Jul 14, 2021 (ESA)
Planetary astronomers have studied Jupiter's spectacular X-ray auroral emission for decades. The X-ray 'colours' of these auroras show that they are triggered b...
