Magnetic Fields Could Significantly Influence Oscillations in Merging Neutron Stars, Study Finds
Magnetic fields may play a bigger role in neutron star mergers than previously thought. A new study using advanced simulations shows that these fields can shift or suppress oscillation frequencies, altering gravitational wave signatures. This discovery could change how astronomers decode post-merger signals and refine models of neutron star interio...

New Polar Cataclysmic Variable Identified by Astronomers: What You Need to Know
Astronomers have detected ZTF J0112+5827, a newly identified polar cataclysmic variable. This binary system, composed of a white dwarf and a low-mass donor star, features an 80.9-minute orbital period and a strong magnetic field of 38.7 MG. It lacks an accretion disk, with emissions mainly from its accretion stream and magnetic field lines. The sys...

Black Hole Singularities May Not Exist, Say Scientists
A new study questions the existence of black hole singularities, suggesting refinements to Einstein’s equations using quantum gravity concepts. Researchers argue that infinite density points may not be real, replacing them with highly curved but finite regions of space-time. While direct observation remains difficult, gravitational waves and earl...

Gravitational Waves Reveal Black Hole Ancestry Through Spin Analysis
A study published in Physical Review Letters explores how gravitational waves reveal the ancestry of black holes. By examining 69 black hole mergers, researchers found that spin shifts indicate repeated collisions in dense star clusters. This insight supports models suggesting black holes grow through sequential mergers. Observatories like LIGO and...

Astronomers Observe Black Hole Reactivate, Emitting Jets of Plasma
A supermassive black hole at the center of galaxy 1ES 1927+654 has been observed reactivating after a quiet period. Jets of hot gas were released from both sides of the black hole, surprising astronomers. Researchers speculate that a white dwarf star in close orbit may be interacting with the black hole, providing key insights into cosmic behavior....

Astronomers Discover Unusual X-Ray Oscillations From a Black Hole 100 Million Light-Years Away
A supermassive black hole 100 million light-years away is showing an unprecedented increase in X-ray oscillations, starting from 18-minute intervals and accelerating to 7 minutes in just two years. Astronomers believe a white dwarf, orbiting perilously close to the event horizon, is causing these flashes. The findings offer a glimpse into black hol...

Astronomers Seek Binary Supermassive Black Holes in Galactic Centers
Astronomers have detected possible binary black holes at the centres of galaxies, using light patterns from active galactic nuclei as key indicators. The study of PG 1553+153, in particular, shows evidence of a 20-year variation, pointing to a system of two supermassive black holes. If confirmed, this could provide new insights into galaxy formatio...

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...
