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 ..

Astronomers at Max Planck Institute of Germany discover a new black hole named Holmberg 15A
Astronomers at the Max Planck Institute of Germany have recently discovered a new black hole named Holmberg 15A that is clocking in at 40 billion times the mass of the Sun. The black hole is supergiant elliptical galaxy i.e. around 700 million light-years away from Earth and resides right at the centre of the Abell ..

Gravitational Waves
Gravitational Waves were for the first time discovered in February, 2016, 100 years after they were hypothesized by Albert Einstein in 1916. These waves were detected by the scientists working at two LIGO (Laser Interferometer Gravitational-wave Observatory) facilities in United States. LIGO scientists detected these gravitational waves produced by collision of two black holes located ..

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 ..
