Juno's Latest Flyby of Jupiter Captures Two Massive Storms

Pasadena CA (JPL) Jan 21, 2019
This image of Jupiter's turbulent southern hemisphere was captured by NASA's Juno spacecraft as it performed its most recent close flyby of the gas giant planet on Dec. 21, 2018.
This new perspective captures the notable Great Red Spot, as well as a massive storm called Oval BA. The storm reached its current size when three smaller spots collided and merged in the year 2000. The Great Red Spot, which is about twice as wide as Oval BA, may have formed from the same process centuries ago.
Juno captured Oval BA in another image earlier on in the mission on Feb. 7, 2018. The turbulent regions around, and even the shape of, the storm have significantly changed since then. Oval BA further transformed in recent months, changing color from reddish to a more uniform white.
Juno took the three images used to produce this color-enhanced view on Dec. 21, between 9:32 a.m. PST (12:32 p.m. EST) and 9:42 a.m. PST (12:42 p.m. EST). At the time the images were taken, the spacecraft was between approximately 23,800 miles (38,300 kilometers) to 34,500 miles (55,500 kilometers) from the planet's cloud tops above southern latitudes spanning 49.15 to 59.59 degrees.
Citizen scientists Gerald Eichstadt and Sean Doran created this image using data from the spacecraft's JunoCam imager.

Juno captures images of volcanic plumes on Jupiter's moon Io
San Antonio TX (SPX) Jan 01, 2019
A team of space scientists has captured new images of a volcanic plume on Jupiter's moon Io during the Juno mission's 17th flyby of the gas giant. On Dec. 21, during winter solstice, four of Juno's cameras captured images of the Jovian moon Io, the most volcanic body in our solar system. JunoCam, the Stellar Reference Unit (SRU), the Jovian Infrared Auroral Mapper (JIRAM) and the Ultraviolet Imaging Spectrograph (UVS) observed Io for over an hour, providing a glimpse of the moon's polar regions as ... read more
