Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have observed a pair of galaxies known as Arp 269. They detected extended tidal tails emerging from this system. The finding was ...
Scientists are asking for the public's help to find the origin of hundreds of thousands of galaxies that have been discovered by the largest radio telescope ever built: LOFAR. Where do these mysterious objects that extend ...

(Phys.org)—Mexican astronomers report the discovery of seven new large extragalactic radio sources called giant radio galaxies (GRG). The GRGs were found by visual inspection of radio images provided by two astronomical ...
Using the Large Area Telescope (LAT) onboard NASA's Fermi spacecraft, astronomers have investigated a nearby radio galaxy known as NGC 3894. Results of the study, presented in a paper published March 3, confirm the galaxy's ...
An array of 350 radio telescopes in the Karoo desert of South Africa is getting closer to detecting "cosmic dawn"—the era after the Big Bang when stars first ignited and galaxies began to bloom.
