#PPOD: Over the Southern Ocean surrounding Antarctica, winds can whip around the globe relatively unimpeded by land. Intrepid sailors termed these southern latitudes the Roaring Forties, Furious Fifties, and Screaming Sixties on account of the strong prevailing winds. When those winds encounter a barrier like an island, the disruption in airflow can be beautiful. One impediment, shown here, is remote Peter I Island. Credit: NASA Earth Observatory/Michala Garrison

#PPOD: The colors in this image from the NASA/ESA Hubble Space Telescope tell a story about density in the Trifid Nebula, a star-forming region about 5000 light-years from Earth. The top left, where it is bright blue, has the least dust. Here, powerful ultraviolet light stripped electrons from nearby gas, creating a glow, with winds creating a bubble by clearing out surrounding dust. Credit: NASA, ESA, STScI. Processing: J. DePasquale (STScI)

#PPOD: A vast cavity on the Red Planet looks back at ExoMars Trace Gas Orbiter (TGO) with an icy stare. The crater is located in Utopia Planitia, the largest known impact basin in the Solar System, with a diameter of roughly 3,300 km, or twice the size of Earth’s Sahara Desert from north to south.

#PPOD: This new JWST picture features a cosmic creepy-crawly called NGC 6537 — the Red Spider Nebula. Using its Near-InfraRed Camera (NIRCam), JWST has revealed never-before-seen details in this picturesque planetary nebula with a rich backdrop of thousands of stars. Planetary nebulae like the Red Spider Nebula form when ordinary stars like the Sun reach the end of their lives. Credit: ESA, NASA & CSA, J. H. Kastner (Rochester Institute of Technology)
