MeerKAT Detects Gravitational Wave Background, Uncovering Cosmic Activity
Scientists using the MeerKAT Pulsar Timing Array have made a groundbreaking discovery, confirming the presence of a gravitational wave background in the universe. This unexpected phenomenon, detected with unprecedented precision, suggests that supermassive black hole collisions may occur more frequently than previously thought. By observing the sig...

Scientists Develop New Approach to Capture Gravitational Wave Memory from Supernovae
A study published in Physical Review Letters highlights new methods to detect the gravitational wave memory effect, a unique phenomenon predicted by Einstein's general relativity. Core-collapse supernovae (massive stellar explosions) generate these low-frequency gravitational waves, offering a rare glimpse into stellar interiors. Despite their weak...

New Theory Suggests Gravitational Waves Could Solve Black Hole Information Paradox
A new study proposes a potential solution to the long-standing black hole information paradox, suggesting that black holes might leak information through gravitational waves. Researchers at the California Institute of Technology have explored how quantum nonlocality could connect the interior of a black hole with its exterior. This connection would...

Arecibo Observatory Data Helps SETI Uncover Secrets of Pulsar Signals and Cosmic Distortions
Data from the now-collapsed Arecibo Observatory continues to drive major discoveries in space science. Sofia Sheikh and her team from the SETI Institute utilised archived data to investigate the signals of pulsars—dense neutron stars emitting radiation like cosmic lighthouses. Their study focused on how these signals are distorted by interstellar...

Astronomers Explore Moon as Vantage Point for Space Studies: Report
A recent symposium at the Raman Research Institute (RRI) in Bengaluru brought together over 60 scientists and researchers to discuss the Moon’s role as a vantage point for advanced astronomical studies. Organised by RRI and the U.R. Rao Satellite Centre (URSC) of ISRO, the three-day event focused on leveraging the Moon’s unique environment for ...

Dark Matter Could Be Linked to a ‘Dark Big Bang’, New Study Suggests
New research suggests that dark matter may have originated from a "Dark Big Bang," a cosmic event distinct from the standard Big Bang. Proposed by scientists at Colgate University, the theory explores scenarios where dark matter could have been introduced into the universe up to a year after the initial Big Bang. Unlike regular matter, dark matter ...

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...

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...
