Astronomers think they may have found the most powerful pulsar to date in a distant galaxy. The fast-spinning neutron star — the dense remains of a once massive star — is just beginning to emerge from ...

Composite image of Swift J1818.0−1607, the youngest pulsar ever observed, as seen by the EPIC-pn camera on ESA’s XMM-Newton. The image combines observations in the following energy bands: 2–4 keV (red ...

Magnetars are among the most bizarre and mysterious objects in the universe, packing in trillions of times more magnetic pull than the Earth or any magnet developed by humans. Scientists are still ...

A teaspoon that weighs a billion tons? Welcome to the world of neutron stars the ultra-dense cores left after colossal supernovae. In this video, we break down how these objects form (from the iron ...

Astronomers have added a new species to the neutron star zoo, showcasing the wide diversity among the compact magnetic remains of dead, once-massive stars. While it’s an oddball, some of this newfound ...

Mysterious radio wave pulses from deep in space have been hitting Earth for decades, but the scientists who recently discovered them have no concrete explanation for the origin of the signals. The ...

What is the origin of fast radio bursts (FRBs) and what can this teach us about the galaxies where they reside? This is what a recent study published in Nature hopes to address as a team of ...
