#PPOD: Twice each day, tides ebb and flow through a maze of sandy channels, mudflats, and mangrove forests that flank the 88 islands and islets of Guinea-Bissau’s Bijagós Archipelago. Seen from above in this image from Nov. 28, 2025, the process leads to stark changes to the landscape: around low tide, intertidal mudflats and sandflats emerge from the sea, causing islands to grow significantly before shrinking again hours later.

#PPOD: Visible in this observation is a section of Cerberus Fossae, Mars (width approximately 250 meters), which comprises a series of rifts located in Elysium Planitia just north of the Martian equator. The fossae (Latin plural for a “ditch” or “depression”) are in close proximity and related to the formation of Athabasca Valles, which lies to the west. These rifts are collapse features believed to form by volcanic and tectonic processes. Credit: NASA/JPL-Caltech/University of Arizona

#PPOD: The largest and most detailed photo ever made of our Milky Way galaxy’s center in visible light is revealed in this cutout image from ESA’s Euclid mission. Packed with more than 60 million stars, this image opens the door for scientists to confirm the existence of any exoplanet found in this region and measure its mass using tiny changes in starlight over time.

#PPOD: These images depict different angles of a very peculiar asteroid named (44) Nysa. Located at the inner edge of the asteroid belt, it reveals an unusual structure. The data show that the asteroid is 80 km across and is composed of three distinct blobs, or ‘lobes’, joined by two narrower sections that encircle the asteroid, or ‘necks’. All previous identifications of asteroids with a neck have been interpreted as having just two lobes. Credit: ESO/K. Minker et al.

#PPOD: At first glance, this is just another image of Earth. But look closely, and you will be able to make out Proba-3’s Coronagraph spacecraft hiding in plain sight, covering parts of the Indonesian Archipelago to the right of the Indian Ocean’s vast expanse. While the pictured Coronagraph only has eyes for the Sun and its surrounding corona, the other spacecraft – the Occulter – uses a camera system to autonomously adjust its position relative to the Coronagraph.

#PPOD: NASA's Curiosity Mars rover captured these clouds just after sunset on March 19, 2021, the 3,063rd Martian day, or sol, of the rover's mission. The image is made up of 21 individual images stitched together and color corrected so that the scene appears as it would to the human eye. The clouds are drifting over "Mont Mercou," a cliff face that Curiosity has been studying. The rover captured the image using its Mast Camera (Mastcam). Credit: NASA/JPL-Caltech/MSSS

#PPOD: Amateur astronomer Joël Lapointe was using Google Maps to plan a camping vacation in 2024 when he came across a feature in Quebec's Côte-Nord region that reminded him of an impact crater. He reported the finding, and now field investigations have found geological evidence that this previously unknown feature is indeed a crater from an impact 390 million years ago.

#PPOD: Although models suggest globular star cluster Omega Centauri should contain approximately 10,000 stellar-mass black holes, observational evidence has remained scarce. A team of astronomers recently analyzed archival Hubble and recent JWST data and detected a visible main-sequence star orbiting a stellar-mass black hole. The main-sequence star companion is encircled and shown in greater detail. Credit: ESA, NASA, Maximilian Häberle (MPIA), Joseph DePasquale (STScI)

#PPOD: This enhanced-color image from NASA's Juno spacecraft captures the striking cloud bands of Jupiter's southern latitudes. Jupiter is not only the largest planet in the solar system, but it also rotates at the fastest rate, completing a full day in just 10 hours. This rapid spinning creates strong jet streams, separating Jupiter's clouds into bright zones and dark belts that wrap around the planet.

#PPOD: This image, taken with ESO’s Very Large Telescope, shows Beta Pictoris d, a new planet found orbiting the star Beta Pictoris. The star is at the center of the frame and was subtracted during data processing, revealing the environment around it. The new planet, indicated with an arrow, is the third one found around this star. The other two are Beta Pictoris b (left of the star) and Beta Pictoris c, orbiting much closer to the star and not seen here. Credit: ESO/B. Sutlieff, M. Bonse et al.

#PPOD: As of June 23, 2026, NASA’s Lunar Reconnaissance Orbiter (LRO) has spent an incredible 17 years orbiting the Moon, and the Lunar Reconnaissance Orbiter Camera (LROC) has been hard at work ever since.
This lunar volcano is so ideally shaped and is evidence of ancient explosive eruptions of highly silicic magmas in the Moon’s distant past. There are multiple areas on the Moon where explosive eruptions have occurred, but none is as picture-perfect as this one!

#PPOD: This image is quite extraordinary, and it's not the big disk that's attracting the most attention. Although the planet PDS 70c (just inside the disk) is newly formed and, interestingly, similar in size and mass to Jupiter, it's the fuzzy patch around it that's causing the commotion. That fuzzy patch is thought to be itself a dusty disk that is now forming into moons -- and that has never been seen before. Credit: ALMA (ESO/NAOJ/NRAO)/Benisty et al.

#PPOD: China’s Tianwen-2 spacecraft has arrived at Kamoʻoalewa, a tiny asteroid that travels alongside Earth as one of only a handful of known quasi-satellites. Some researchers suspect this unusual object may be a fragment blasted from the Moon long ago, and Tianwen-2 is now poised to help solve the mystery. Tianwen-2 will attempt to collect a sample from Kamoʻoalewa’s surface before spending months mapping and studying the asteroid from orbit. Credit: CNSA #space #science
