Aug 12, 2020 (SPX)
The tool, developed by scientists from SISSA in Trieste and the University of California at Los Angeles and recently published in Nature Communications, allows ...
Huge ring-like structure on Ganymede's surface may have been caused by violent impact
Aug 12, 2020 (SPX)
Based on the results of a computer simulation conducted using the "PC Cluster" at the National Astronomical Observatory of Japan (NAOJ), it is speculated that t...
Shallow Lightning and Mushballs reveal ammonia to Juno scientists
Aug 07, 2020 (SPX)
Other new findings suggest the violent thunderstorms for which the gas giant is known may form slushy ammonia-rich hailstones Juno's science team calls "mushbal...
Ammonia sparks unexpected, exotic lightning on Jupiter
Aug 07, 2020 (SPX)
The work was published Aug. 5 in the journal Nature. Jupiter's gaseous atmosphere seems placid from a distance, but up close the clouds roil in a turbulent, che...
