New data suggests that supermassive black holes behaved differently in the early universe

New findings challenge a 50-year quasar law, revealing that the UV-to-X-ray relationship has evolved over cosmic time. Large-scale X-ray data from eROSITA and XMM-Newton prompt a re-examination of black hole growth and cosmic measurements.
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).
