Chinese Astronomers Use Insight-HXMT to Decode X-ray Outburst of Binary Star System
In a recent study published on July 24 via arXiv, astronomers from Wuhan University have detailed the powerful X-ray outburst of the Be/X-ray binary system RX J0440.9+4431. Using China’s Insight-HXMT satellite, the team tracked the event from its eruption in December 2022 through March 2023.

PSR J0922+0638 Pulsar Keeps Glitching Every 550 Days, Scientists Are Intrigued
PSR J0922+0638, an ultradense neutron star, shows puzzling rotational glitches every 550 days. Using 22 years of radio data, scientists detected both abrupt and slow changes in its spin. These may be linked to magnetic field cycles or superfluid dynamics deep inside the star. However, the exact cause remains a mystery, demanding continued long-term...

New Study Confirms TeV Halos Are Common in Middle-Aged Pulsars
A recent study by researchers from the U.S. and Mexico using data from the HAWC Observatory has confirmed that TeV halos are a universal feature of middle-aged pulsars. These extended regions of gamma-ray emission are significantly larger than pulsar wind nebulae and may help identify otherwise undetectable pulsars. The findings challenge existing ...

NASA Reveals a Fracture in Huge Cosmic Bone: Everything You Need to Know
With the use of the Chandra X-Ray Observatory, NASA has detected a fracture in the Milky Way. The bone is a galactic center filament that is based at a distance of 26,000 light years from Earth. The fracture would have occurred due to collisions with the neutron star, known as a pulsar, that spins rapidly. The scientists suspect that the fracture w...

NASA Telescopes Reveal Hidden Properties of X-Ray Pulsar RX J0032.9-7348
A joint study using NASA’s NuSTAR and NICER telescopes has shed new light on RX J0032.9-7348, an X-ray pulsar in the Small Magellanic Cloud first identified 30 years ago. The pulsar exhibited a 7.02-second pulse period and underwent a significant X-ray brightening event in October 2024. Researchers noted a double-peaked pulse profile and measured...

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...

NASA Hubble Space Telescope Helps Confirm the First Solitary Black Hole
In the Sagittarius constellation, a lone and first-ever solitary black hole has been discovered by a team of scientists. Although the discovery began in the year 2011, the observations have confirmed it recently. The size of this black hole is as massive as seven times of the sun. Despite the conflicts and differences of observations by another tea...

NASA’s Hubble Space Telescope Tracks a Neutron Star With Mysterious Origin
NASA’s Hubble Space Telescope spotted a rogue magnetar, dubbed SGR 0501+4516, traversing our galaxy for a significantly long time. As per claims by scientists, it was first discovered in the year 2008 by NASA's Swift Observatory as intense flashes of gamma rays in the outer area of the Milky Way

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...
