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).
In the weightlessness of the Space Station, the war between viruses and bacteria changes rules. The result? New biological weapons against superbugs on Earth.
On Earth, gravity and convection currents help viruses (phages) bump into bacteria. In space, those forces vanish.
How does a white dwarf explode? New observations of SN 2024gy provide smoking gun evidence for a specific, violent chain reaction.
Type Ia supernovae are standard candles for measuring the universe, but we still debate how they ignite.
