The electric sands of Titan

Experiments suggest the particles that cover the surface of Saturn’s moon, Titan, are ‘electrically charged.’ When the wind blows hard enough, Titan’s non-silicate granules get kicked up and start to hop in a motion. As they collide, they become frictionally charged, like a balloon rubbing against your hair, and clump together in a way not observed for sand dune grains on Earth — they become resistant to further motion. …

Stars born in winds from supermassive black holes

Observations using ESO’s Very Large Telescope have revealed stars forming within powerful outflows of material blasted out from supermassive black holes at the cores of galaxies. These are the first confirmed observations of stars forming in this kind of extreme environment. The discovery has many consequences for understanding galaxy properties and evolution. …
