Hubble Snaps a Beautiful New Portrait of Jupiter
The Hubble Space Telescope has captured a new portrait of Jupiter that shows the gas giant’s details, including the Great Red Spot, in a more intense color palette than in the past.
Here’s NASA’s description of what’s seen in the shot:
Among the most striking features in the image are the rich colors of the clouds moving toward the Great Red Spot, a storm rolling counterclockwise between two bands of clouds. These two cloud bands, above and below the Great Red Spot, are moving in opposite directions. The red band above and to the right (northeast) of the Great Red Spot contains clouds moving westward and around the north of the giant tempest. The white clouds to the left (southwest) of the storm are moving eastward to the south of the spot.
All of Jupiter’s colorful cloud bands in this image are confined to the north and south by jet streams that remain constant, even when the bands change color. The bands are all separated by winds that can reach speeds of up to 400 miles (644 kilometers) per hour.
On the opposite side of the planet, the band of deep red color northeast of the Great Red Spot and the bright white band to the southeast of it become much fainter. The swirling filaments seen around the outer edge of the red superstorm are high-altitude clouds that are being pulled in and around it.
The Great Red Spot is a towering structure shaped like a wedding cake, whose upper haze layer extends more than 3 miles (5 kilometers) higher than clouds in other areas. The gigantic structure, with a diameter slightly larger than Earth’s, is a high-pressure wind system called an anticyclone that has been slowly downsizing since the 1800s. The reason for this change in size is still unknown.
The new portrait was captured as part of the Outer Planets Atmospheres Legacy (OPAL) program, which provides yearly global views of the outer planets in our solar system. The photos help astronomers study changes in things like storms, winds, and clouds.
