#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.
