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 ...

Like anthropologists piecing together the human family tree, astronomers have found that a misfit “skeleton” of a star may link two different kinds of stellar remains. The mysterious object, called ...

Astronomers have spotted a rare cosmic duo: a neutron star that rotates nearly a hundred times every second locked in an ultra-tight orbit with a semi-shredded star. The scientists who found the pair ...

Like cosmic lighthouses sweeping the universe with bursts of energy, pulsars have fascinated and baffled astronomers since they were first discovered 50 years ago. In two studies, international teams ...

Every 4 milliseconds, a dead star blasts a powerful beam of radiation toward our planet. Don't worry — Earth will be fine. It's the dead star's tiny companion that's in trouble. In a new study ...

A fast-spinning pulsar hungrily feeding on a close companion star has been found 3,000 light-years from Earth in a rare type of cannibalistic system known as a black-widow binary. Around two dozen ...

A rapidly spinning dead star’s wacky fluctuations in brightness are due to the extreme environment surrounding the object, according to a team of astronomers who observed it. Pulsars are fast-spinning ...

This visualization shows 294 gamma-ray pulsars, first plotted on an image of the entire starry sky as seen from Earth and then transitioning to a view from above our galaxy. The symbols show different ...

The James Webb Space Telescope has turned up a world that looks more like a squeezed citrus fruit than a planet, a distorted exoplanet locked in a frantic orbit around a rapidly spinning pulsar.
