Using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope, astronomers have detected a bright, millisecond-duration radio burst from a galactic magnetar known as SGR 1935+2154. The discovery of such ...
(Phys.org)—A team of researchers working at Australia's Parkes Observatory has found the source of at least one kind of peryton—a type of radio signal similar to Fast Radio Bursts (FRBs) which are known to come from somewhere ...
CSIRO astronomers have revealed the hidden face of an enormous galaxy called Centaurus A, which emits a radio glow covering an area 200 times bigger than the full Moon.
