When tiny particles enter Earth’s atmosphere, a newly described series of chemical reactions may lead to production of phosphorus-containing molecules that are essential for biological processes.
Serendipitous observations by the Juno spacecraft while it was en route to Jupiter suggest a Martian source for the dust, but how the dust escapes Mars or its moons remains unknown.
New analysis of Hubble Space Telescope images suggests that Fomalhaut b, once believed to be an extrasolar planet, is, in fact, a cloud of dust that likely formed from the collision of enormous asteroids.
A small pile of dust grains older than the Sun brings new evidence about the rate at which stars are born in the Milky Way.
Close-up images of Ryugu, a near-Earth asteroid and the target of the Hayabusa2 sample return mission, reveal a rocky, dustless world that may have formed from a giant collision.

A plume of water ice that escapes Saturn’s moon Enceladus should be coursing with electrical currents, but data are mixed. Now simulations suggest that a sticky dust cloud may shield signals.
A new analysis of lava from the deep mantle indicates that water-soaked dust particles, rather than a barrage of icy comets, asteroids, or other bodies, delivered water to the newly forming Earth.
Tons of cosmic dust enter Earth’s atmosphere each day, triggering a range of phenomena that scientists are only just beginning to understand.
