Data reanalysis suggests Saturn's largest moon isn't an open ocean world.

New findings from NASA's Cassini mission suggest that Titan, Saturn's largest moon, has a thick, slushy interior rather than a vast global subsurface ocean. This discovery, indicated by a 15-hour gravitational lag and higher energy loss, proposes that the slushy layer may even enhance the potential for life by concentrating nutrients in pockets of water.
China's FAST telescope—the largest on Earth—has scoured the archives to find 19 pulsars missed by previous searches, including rare "transient" ghosts.
Pulsars (spinning neutron stars) are lighthouses of the cosmos. Most are found near the Galactic Plane, where stars are dense.
In space, fire doesn't rise. It forms a ghostly sphere that is harder to detect and harder to kill. New research aims to tame flames for the journey to Mars.
On Earth, hot air is lighter than cold air. It rises, pulling fresh oxygen in from below. This convection gives fire its familiar teardrop shape and yellow color (soot).
Jupiter's outermost moon is a battered, icy archive of the early solar system. New thermal imaging is finally peeling back its scarred surface to reveal what lies beneath.
Using the ALMA telescope, researchers analyzed thermal data to peer into the top few centimeters of Callisto's surface (regolith).
