It's Jupiter.
NASA notes:
See swirling cloud formations in the northern area of Jupiter's north temperate belt in this new view taken by NASA’s Juno spacecraft.
The color-enhanced image was taken on Feb. 7 at 5:42 a.m. PST (8:42 a.m. EST), as Juno performed its eleventh close flyby of Jupiter. At the time the image was taken, the spacecraft was about 5,086 miles (8,186 kilometers) from the tops of the clouds of the planet at a latitude of 39.9 degrees.
Citizen scientist Kevin M. Gill processed this image using data from the JunoCam imager.
