New unusual and repeating fast radio burst detected 3 billion light-years away

The cosmic object is distinctive compared to other radio burst detections in recent years, according to new research. Fast Radio Bursts, or FRBs, are millisecond-long bursts of radio waves in space. Individual radio bursts transmit once and do not repeat. But repeating fast radio bursts are known to send short, energetic radio waves multiple times. …

Strange ‘unknown structure’, faint radio glow thousands of light-years wide, found around nearest quasar

A new technique for studying some of the brightest objects in the universe has upended scientists’ understanding of the link between active monster black holes and suppressed star formation. Quasars are the ultra-luminous nuclei of galaxies that contain supermassive black holes. The intense radiation from a quasar comes from massive amounts of hot gas forming …
