On 25 August, the Hubble Space Telescope checked in on Jupiter, capturing another stunning view of the giant planet, the Great Red Spot and a new storm boiling up in the mid-northern latitudes. The frozen moon Europa is visible at left. The GRS, measuring about 15,700 kilometres (9,800 miles) across and rotating counterclockwise, displays an especially red colour as it plows into the clouds ahead. Another storm, dubbed Oval BA and nicknamed Red Spot Jr., is visible just below its famous counterpart, appearing to darken slightly and suggesting a possible return to a more reddish hue. Hubble captured the new image as part of the Outer Planets Atmospheres Legacy program – OPAL – which keeps tabs on changes in the atmospheres of Jupiter, Saturn, Uranus and Neptune.
Observations with the National Science Foundation’s Very Large Array (VLA) have given astronomers an unprecedented look into the atmosphere of Jupiter. The scientists used the VLA to study the dynamics of Jupiter’s atmosphere from the visible cloud surfaces down to about 60 miles (100 kilometres) below the clouds.
