Arecibo Telescope: Key Facts

Built in 1963, Puerto Rico’s Arecibo Telescope was built in 1963. It is the second-largest single-dish radio telescope in the world. It was in news recently because of its collapse. It is owned by the US National Science Foundation. It is known for its finding that Mercury rotates in 59 days and not 88 days ..

LIGO detects first merger of two unequal-mass black holes

The scientists of Laser Interferometer Gravitational Wave Laboratory (LIGO) have recently recorded the first merger of black holes that were of unequal masses. On April 12, 2020, the LIGO-Virgo collaboration detected collision between two black holes that were 2.4 billion light years away. The scientists have now concluded from their researches and analysis that these ..

LIGO: Second Merger of Neutron Stars detected

The LIGO (Laser Inferometer Gravitational-wave Observatory) detected gravitational waves due to collision of two neutron stars. This is the second time the gravitational waves are being detected. Highlights The mass of the neutron stars detected is expected to be 3.3 times and 3.7 times as that of the sun. The scientists believe that the neutron ..

Scientists detect Gravitational waves for fourth time

Scientists have successfully detected gravitational waves for fourth time coming from merger of two massive black holes. It was for first time, these waves were simultaneously detected by US-based Laser Interferometer Gravitational-wave Observatory (LIGO) and Italy-based Virgo detectors. The first two detection were made in September and December 2015 in quick succession and for third ..
