Hubble’s September 4th photo of Jupiter displays the ever-changing landscape of its turbulent atmosphere, where several new storms are making their mark, and the pace of color changes near the planet’s equator is continuing to surprise researchers.
The planet’s equatorial zone has remained a deep orange hue for a much longer time, compared to previous darkening episodes. While the equator has changed from its traditional white or beige appearance for a few years now, scientists were surprised to find the deeper orange color to persist in Hubble’s recent imaging, instead expecting the zone to lose its reddish haze layer.
Just above the equator, researchers note the appearance of several new storms, nicknamed “barges” during the Voyager era. These elongated red cells can be defined as cyclonic vortexes, which vary in appearance. While some of the storms are sharply defined and clear, others are fuzzy and hazy. This difference in appearance is caused by the properties within the clouds of the vortexes.
Researchers also note that a feature dubbed “Red Spot Jr.” (Oval BA), below the Great Red Spot, where Hubble just discovered winds are speeding up, is still a darker beige color, and is joined by a string of white, anticyclonic storms to the south.

| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the WFC3 instrument on the Hubble Space Telescope. Several filters were used to sample medium wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F395N, Green: F502N, Red: F631N |
