Wong (University of California, Berkeley) and the OPAL team Simon (Goddard Space Flight Center), and M.H. In observations taken on 7 September 2021, researchers found that Neptune’s dark spot, which recently was found to have reversed course from moving toward the equator, is still visible in this image, along with a darkened northern hemisphere. Hubble's crisp views of Jupiter in 2020 was one of the most popular ESA/Hubble photo releases to date. 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 several additional white, cyclonic storms to the south. This difference in appearance is caused by the physical properties within the clouds of the vortices. While some of the storms are sharply defined and clear, others are fuzzy and hazy. Just above the equator, researchers note the appearance of several new storms, nicknamed "barges." These elongated red cells can be defined as cyclonic vortices, which vary in appearance. While the equator has departed from its traditional white or beige appearance for a few years now, scientists were surprised to find a deeper orange in Hubble's recent imaging, when they were expecting the zone to cloud up again. The planet's equatorial zone is now a deep orange hue, which researchers are calling unusual. Hubble's 4 September photo puts the giant planet's tumultuous atmosphere on full display. This year's Hubble observations of Jupiter track the ever-changing landscape of its turbulent atmosphere, where several new storms are making their mark and the planet's equator has changed color yet again.
