aurorae

A two-panel horizontal image. On the left is Neptune observed by the Hubble Space Telescope. It is a blue circle, tilted about 25° to the left. There are white smudges at 7 o’clock and just above 5 o’clock. At right is an opposing view of the planet, using data from Hubble and JWST. It is a multihued blue orb. There are white smudges in the same spots as the image on the left but also at the center of the planet and at the top. There are cyan smudges vertically along the right side, and the top of these areas is more translucent than the bottom.
