Feeling a bit melancholy today. Tell me about your favorite rock. Can be your favorite rock type, rock formation, or even a very specific hunk of rock. I will also accept minerals. Photos welcome.

🌌 August’s Planetary Geomorphology Image of the Month is here! Pluto’s bladed terrain is one of the dwarf planet’s most enigmatic landscapes. Victor Belissa explores how these huge ridges may have formed through sublimation waves driven by Pluto’s near-surface winds. 🧊💨🌑 #Pluto #PlanetaryScience

Revisiting the Enigma of Pluto’s Most Enigmatic Terrain: The Bladed Deposits of Tartarus Dorsa

Post contributed by Victor Belissa (Phd student), Laboratoire de Planétologie et Géosciences (LPG), Nantes Université, CNRS, France. When NASA’s New Horizons spacecraft flew past Pluto in 201…

How are ocean waves and earthquakes linked? A new study combines buoy wave height measurements with NSF NGF seismic data to examine how winter ocean swells impact seismicity at California’s offshore Mendocino Triple Junction. Read it here: doi.org/10.1785/0220250447

A comic illustrating how wave height measurements and fifteen years of seismic observations draw a connection between seismicity and ocean-waves. The comic features anthropomorphized borehole seismometers and a wave rider instrument collaborating to study the seasonal changes in seismicity.

The only taxidermied blue whale in the world, 1865 CE, now housed at the Natural History Museum in Sweden. The public was allowed to enter the whale up until a couple was found having sex inside it. Now the whale’s jaws are opened only for special occasions, such as Swedish election days.
