Discovery of second repeating fast radio burst raises new questions

An international team of astronomers has discovered a permanently active second fast radio burst, raising questions about the nature of the mysterious phenomenon. Fast radio bursts (FRB) are intense, brief flashes of radio frequency emissions, lasting on the order of milliseconds. The phenomenon was discovered in 2007 by graduate student David Narkevic and his supervisor …

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. …

Massive and unknown radio structure detected around the brightest quasar in the universe

Astronomers have discovered two large mysterious objects erupting from the brightest black hole in the known universe. Discovered during a 1959 survey of the cosmos radio wave sources, the supermassive black hole 3C 273 is a quasar – short for “quasi-stellar object”, because the light emitted by these behemoths is bright enough to be mistaken …

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 …
