Astronomers discover dying echoes of a supermassive black hole

Japanese astronomers have discovered the echoes of a “dying” supermassive black hole. While the object is quiet now, the team spotted the signatures of two huge radio jets that indicate it only recently fell silent after a bright, active phase.Continue… Continue reading Astronomers discover dying echoes of a supermassive black hole

Five fast radio bursts tracked to home galaxies

Astronomers are another step closer to solving one of the most intriguing cosmic mysteries of recent times – fast radio bursts (FRBs). A team has now traced five signals to their points of origin within the spiral arms of galaxies, narrowing down the l… Continue reading Five fast radio bursts tracked to home galaxies
