Ammonia-Rich Hail Sheds New Light on Jupiter's Weather
Cyclone observed in Jupiter’s northern hemisphere by JunoCam in July 2018. The central part covers an area of 3200 x 3800 km. White clouds of ammonia can be seen, rotating anticlockwise. Clouds rising as much as 15 km above the others (based on the shadow they cast) are visible in several places, especially in the upper central part of the cyclone. These storms are thought to contain a kind of water-ammonia hail (‘mushballs’) specific to Jupiter’s atmosphere, which drags the ammonia down into the deep atmosphere and may explain the presence of shallow lightning flashes.

Surprisingly Dense Exoplanet Challenges Planet Formation Theories
noirlab2018a – Artist’s impression of K2-25b
New detailed observations with NSF’s NOIRLab facilities reveal a young exoplanet, orbiting a young star in the Hyades cluster, that is unusually dense for its size and age. Slightly smaller than Neptune, K2-25b orbits an M-dwarf star — the most common type of star in the galaxy — in 3.5 days.

NASA Sun Data Helps New Model Predict Big Solar Flares
An X-class solar flare flashes on the edge of the Sun on March 7, 2012. This image was captured by NASA's Solar Dynamics Observatory and shows a type of light that is invisible to human eyes, called extreme ultraviolet light.
