Supernova Remnants Found in Oceanic Samples, Scientists Look to Moon
Scientists have identified supernova debris in deep-sea sediments, including a rare plutonium isotope linked to a kilonova. Researchers believe a neutron star collision occurred nearly 10 million years ago, scattering radioactive material across space. To validate this theory, they plan to analyze lunar soil, which remains undisturbed by Earth's ge...

Unusual X-ray Flash in Large Magellanic Cloud Puzzles Astronomers
A brief yet intense X-ray flash, XRT 200515, was detected in NASA's Chandra telescope data from 2000. The signal, originating from the Large Magellanic Cloud, has left scientists debating its cause. Possible explanations include a neutron star pulling in gas from a companion star or a powerful flare from a distant magnetar. Researchers also specula...

FAST Telescope Reveals Emission Properties of Three Long-Period Pulsars in New Study
The FAST telescope has observed emission behaviours in three long-period pulsars, revealing null phases, asymmetric pulses, and microstructures. The study highlights variations in pulsar emissions and their periodicity, contributing to a deeper understanding of neutron star radio emissions. Researchers noted different nulling fractions and microstr...

Scientists Investigate Hypernuclei To Understand Subatomic Forces and Neutron Stars
A groundbreaking study on hypernuclei, led by Ulf-G. Meißner from the Institute for Advanced Simulation, uses nuclear lattice effective field theory to explore the interactions of Λ-hyperons within atomic nuclei. The research, published in The European Physical Journal A, provides key insights into the forces that shape hypernuclei and their pote...

Scientists Find the Origin of a Mysterious Fast Radio Burst With a Unique Technique
Researchers have pinpointed the origin of fast radio burst FRB 20221022A to within 10,000 kilometres of a neutron star. Using scintillation analysis, a team from MIT determined that the burst emerged from the magnetosphere, a highly magnetic and chaotic environment surrounding the star. This discovery marks the first conclusive evidence of FRBs ori...

Asteroids Impacting Neutron Stars May Be the Cause of Fast Radio Bursts
Research suggests asteroid impacts on neutron stars may be the cause of mysterious fast radio bursts (FRBs). These collisions release enormous energy and match observed FRB frequency. Scientists believe interstellar objects colliding with neutron stars could account for their rate and occurrence, while repeating FRBs may stem from asteroid belts. O...

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...

Fastest-Moving Stars in the Galaxy May be Piloted by Aliens, New Study Suggests
A recent study proposes that advanced alien civilisations might utilise binary star systems, especially those involving neutron stars, as massive interstellar spacecraft. By ejecting material in specific directions, the stars could generate thrust, moving the system across the galaxy. Known hypervelocity stars with unusual accelerations are suggest...

New Research Explains Zebra Pattern in Radio Waves from Crab Nebula
A new model by Mikhail Medvedev from the University of Kansas offers an explanation for the zebra-like pattern in high-frequency radio waves emitted by the Crab Pulsar. The pattern, first discovered in 2007, is likely caused by diffraction and interference of waves in the pulsar's plasma-rich environment. Medvedev’s model could also provide a met...

Could a Supernova Threaten Earth’s Survival? Here's What You Need to Know
Supernova explosions have the potential to harm Earth’s atmosphere, particularly the ozone layer. However, no stars close enough to cause damage are currently identified. The risks are low, but gamma-ray bursts, caused by neutron star mergers, may pose an even greater threat in the future.

Neutron Star in 4U 1820-30 Spins at Record-Breaking 716 Rotations Per Second
Astronomers have detected a neutron star in the binary system 4U 1820-30 spinning at 716 times per second, breaking records for speed. Located 26,000 light-years from Earth, the star's surface releases explosive thermonuclear bursts that make it shine up to 100,000 times brighter than the Sun. This discovery offers new insights into the extreme pro...

ISRO and IIT Guwahati Discover New Challenges in Theories of X-Ray Pulsar
Researchers from IIT Guwahati and the Indian Space Research Organisation (ISRO) have made a surprising discovery that could reshape our understanding of X-ray pulsars. They found that the X-rays emitted by Swift J0243.6+6124, the first known Galactic Ultraluminous X-ray Pulsar, exhibit an unexpectedly low level of polarization. This pulsar, which i...
