NASA Unveils Prototype Telescope for LISA Mission, Gravitational Wave Detection from Space
NASA has introduced the prototype telescope for its LISA mission, set to detect gravitational waves from space. This mission, a collaboration with the European Space Agency, involves spacecraft using lasers to measure precise distances, enabling the detection of cosmic events like black hole mergers. The prototype telescope, which arrived at NASA...

Black Hole Mergers Explained: What Happens When Two Black Holes Collide in Space?
Black hole mergers are among the most energetic events in space. Two black holes gradually lose energy through gravitational interactions, drawing them closer until their event horizons stretch and merge. Gravitational waves released during the process are some of the most powerful forces in the universe, with part of the black holes' mass converti...

Astronomers Spot Imminent Collision Of Supermassive Black Holes In Nearby Galaxy: Report
Astronomers have detected two closely spaced supermassive black holes in the galaxy MCG-03-34-64, located 800 million light-years away.

Gravitational Waves Suggest Supercool Phase Transition After the Big Bang, Unveiling New Physics
In 2023, scientists detected faint ripples in spacetime, known as gravitational waves, which were initially attributed to a phase transition shortly after the Big Bang. This phase transition was thought to have occurred in the early universe and was believed to generate the low-frequency waves detected by pulsar timing arrays. However, recent resea...

Astrophysicists Detect Black Hole-Neutron Star Mergers For The First Time
Astrophysicists say that the newly observed phenomena will allow them to better understand the formation of binary star systems and how often they merge, something that has never been measured before.

Dozens of Newly-Detected Gravitational-Wave Events May Help Better Understand Black Holes, Neutron Stars
Astrophysicists have found new 39 gravitational-wave events caused by collision of black holes and neutron stars far in the universe. These, along with previously observed 11 events, will help them understand the population of black holes and neutron stars across the universe.

First Black Hole With 'Intermediate Mass' Discovered, Oldest Ever Detected
Scientists announced Wednesday the discovery of a black hole -- the oldest ever detected -- that shouldn't even exist according to the current understanding of cosmic monsters so dense not even light can escape their gravitational pull.

Scientists Spot Light Flare From a Black Hole Collision for the First Time Ever
A team of international astronomers believe that they might have detected light from a black hole merger, for the first time ever. This unprecedented event was noted by scientists at Caltech' Zwicky Transient Facility (ZTF) in California after studying gravitational waves and electromagnetic radiation from the collision of two black holes.
