it completes a rotation in about 3.2 milliseconds, translating to more than three hundred turns each second. Millisecond pulsars belong to the class of neutron stars whose spin rates have been boosted through a recycling process, during which matter...

of yet‑unknown dark‑matter particles, and a hidden swarm of rapidly rotating neutron stars called millisecond pulsars. Separating these possibilities is notoriously difficult because the Galactic Center is one of the brightest and most crowded regions...

NASA’s XRISM mission has unveiled the complex process of how a pulsar captures and manages stellar wind plasma near a neutron star. NASA’s XRISM X-ray observatory has captured an unprecedented look at the violent dance between a pulsar and its massive...

that produce narrow beams of radio waves. As these beams sweep past Earth, they appear as the periodic flashes that give pulsars their name. Illustration showing a pulsar’s twin beams of radio waves sweeping through space. Credit: Nazarii Neshcherenskyi...

Arrays function as a colossal, galaxy-wide detector. By meticulously tracking the arrival times of radio signals from pulsars—rapidly spinning neutron stars that serve as nature’s most accurate clocks—researchers can identify minute distortions in...

Scientists are using lunar lasers and binary pulsars to transform familiar astronomical systems into powerful detectors for ancient gravitational waves. For billions of years, the Moon has traced a steady path around Earth. Now, physicists suggest this...

remains a significant astrophysical mystery, as it challenges standard models of how quickly these objects can grow. Pulsars as Cosmic Detectors Pulsar timing arrays function as galactic-scale sensors by monitoring the steady, rapid rotation of neutron...

of low magnetization and high-energy output positions CTA 1 as a critical case study for understanding how young pulsars distribute energy into their local environments. Unbinned (pixel size 0.5”) image of all CXO observations aligned and merged. In...

the facility. According to JinLin Han, a researcher involved in the study, the FAST program has cataloged approximately 900 pulsars to date. However, PSR J1856–0039 stands out due to its extremely tight, eccentric orbit and the clarity with which it...

NASA Chandra’s 10‑year study shows supernova remnant G292.0+1.8 expanding unevenly, a puzzling clue that could rewrite how we view stellar explosions. Ten years of observations with NASA’s Chandra X‑ray Observatory have exposed an irregular expansion...

The CTAO has completed its four Large-Sized Telescopes in Spain, launching a powerful new era in the study of extreme cosmic events and distant explosions. A major milestone in high-energy astrophysics was reached on October 15 as researchers...

by annihilating dark matter particles, or radiation generated by an undiscovered population of unresolved millisecond pulsars tucked away in the crowded stellar bulge. Yet, both of these prevailing hypotheses come with significant theoretical challenges...

Astronomers have detected an unusual event in a distant galaxy that could finally reveal what happens when two black holes collide. Astronomers have uncovered evidence of a rare cosmic spectacle unfolding at the heart of the galaxy Mrk 501: a potential...

and collapsed into a dense white dwarf. While astronomers have previously theorized about the existence of planets around pulsars, detecting such a companion orbiting a white dwarf indicates that this phenomenon may occur across a broader range of...

Astronomers have discovered a rare supernova that solves a 1,000-year-old mystery, revealing a third, distinct way that stars can explode. Astronomers have long sought to definitively observe an electron-capture supernova, a rare and specific death...
