Bite-sized threads showing stuff working, sometimes not working too. We can learn from both. Check out my site for my latest projects.

The Stickney Crater (the dominant feature on Phobos, one of the two moons of Mars)
Stickney is enormous relative to the moon itself. Phobos is only about 27 km across at its widest, and Stickney is roughly 9 km in diameter. That means the crater takes up a huge fraction of the moon’s surface.
The impact that formed Stickney was so large that it nearly shattered Phobos. You can see long grooves and fractures radiating outward from the crater across the surface. Those are structural stress features from the impact and possibly tidal effects from Mars.
One important detail is that Phobos has very low gravity and is likely a rubble pile body. That means it is loosely held together rather than being a solid monolithic rock. A slightly larger impact could have disrupted it completely.
So it’s not just a big crater. It is the defining geological feature of the moon.

Instead of one monolithic system getting smarter and smarter, they propose that intelligence emerges from interaction between multiple agents, including humans. In that framing, “hybrid social systems” means networks of AIs, humans, institutions, and tools working together. Becoming a well-supported viewpoint, not a proven law of AI development tho

"If intelligence is inherently social, then the path to more powerful #AI runs not through building a single colossal oracle but through composing richer social systems—and these systems will be hybrid," write James Evans, Benjamin Bratton, and Blaise Agüera y Arcas in a new #ScienceExpertVoices article. scim.ag/3PDvhv4

Late night post
A neutron star is so dense that a teaspoon of its material would weigh roughly a billion tons on Earth.
But that’s not even the strangest part.
The gravity is so intense that light itself bends around the surface, so if you stood on one, you could see behind your own head (useful intuition, not literal).
Almost the entire star’s surface would be visible from any single point, up to 80%.
And the surface temperature can get around a million degrees. The “cool” spots are only a few hundred thousand.
Space is wild.

NASA’s IXPE just gave us a fresh look at an ancient stellar wreck. The new image combines IXPE data with observations from Chandra and ESA’s XMM-Newton to study RCW 86, a supernova remnant about 2,000 years old. IXPE’s contribution is the purple-highlighted outer rim, where the mission measured polarized X-rays.
Although pretty, IXPE is NASA’s first mission dedicated to measuring X-ray polarization - which helps scientists infer how magnetic fields are structured and where particles are being accelerated inside extreme objects like supernova remnants, neutron stars, and black holes.
The colors from Chandra and XMM-Newton show different X-ray energies, while IXPE adds information about the orientation of the X-ray light itself. That gives a more detailed view of the shock front where the exploded star’s debris is still plowing into surrounding space.

At magmatic temperatures they exist as complex mixtures of melt, crystals, and dissolved volatiles, so they are inherently multiphase and multicomponent systems.
Their rheology reflects both viscous flow and elastic response. The silicate melt behaves as a highly temperature dependent liquid, while suspended crystals introduce yield stress and shear thinning or thickening depending on concentration and interaction. At the same time, the polymerized structure of the melt allows temporary elastic energy storage, especially at short timescales or high strain rates.
As a result, magma does not follow a simple Newtonian model. Its behavior evolves with temperature, composition, crystal fraction, and deformation rate, which directly controls processes like ascent, fragmentation, and eruption style.
