#PPOD: Mimas, Saturn's innermost large moon, is a small, icy world with a mean diameter of 396 kilometers. The icy moon is notable for its heavily cratered surface, particularly the massive Herschel crater, which gives it a striking resemblance to the Death Star from the Star Wars franchise. This image was captured on January 30, 2017, by NASA's Cassini spacecraft. Credit: NASA / JPL-Caltech / Space Science Institute / CICLOPS

#PPOD: JWST has now captured images of all four gas giants in our solar system: Jupiter, Saturn, Uranus, and Neptune. These images are the first of their kind, and they offer a new and unprecedented view of these distant worlds.

The JWST's image of Jupiter is particularly stunning. The telescope's infrared vision allows us to see through Jupiter's thick clouds, revealing the planet's swirling atmosphere and its Great Red Spot. The planet's haze and auroras steal the show.

#PPOD: This image of Uranus’ aurorae was taken by the NASA/ESA Hubble Space Telescope on 10 October 2022. These observations were made by the Space Telescope Imaging Spectrograph (STIS) and include both visible and ultraviolet data. An international team of astronomers used Hubble to make new measurements of Uranus' interior rotation rate by analyzing more than a decade of the telescope’s observations of Uranus’ aurorae.

#PPOD: A collision between two galaxies has resulted in a merged star system with an unusual appearance and bizarre internal motions. Messier 64 (M64) features a spectacular dark band of absorbing dust in front of the galaxy's bright nucleus, giving rise to its nicknames, the "Black Eye" or "Evil Eye" galaxy.

#PPOD: Astronomers combined observations from three different observatories to produce this colorful, multiwavelength image of the intricate remains of Supernova 1987A. The central structure visible inside the ring in the Hubble image has now grown to roughly half a light-year across. Most noticeable are two blobs of debris in the center of the supernova remnant racing away from each other at approximately 20 million miles per hour.
