The researchers discovered the Treble Clef is likely caused by an outburst from a supermassive black hole, followed by a collision […]

NASA’s Neil Gehrels Swift Observatory captured an “orphan” black hole lighting up as it devoured a star on the outskirts of a faraway galaxy. These phenomena are rare to begin with, and none had ever before been seen so far outside of a galaxy’s core. “We were looking for these star-shredding events as a way […]

Engineers and scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, completed tests this month on a second early version of a key element of the upcoming LISA (Laser Interferometer Space Antenna) mission. The LISA mission, a collaboration between ESA (the European Space Agency) and NASA, will use infrared lasers to detect gravitational waves, […]
