The sweeping beams of cosmic lighthouses called pulsars are much more energetic than previously thought, calling into question the bulbs that power them. A new analysis, from the High Energy ...

On November 28, 1967, astronomers found the first pulsar. A pulsar is a super-dense star that rotates super fast. As the ...

A large team of astronomers and astrophysicists affiliated with several institutions in China has discovered a binary star system, where one of the stars is a millisecond pulsar and the other is made ...

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 ...

The surprising detection of light 200 times more powerful than previous observations from the nearby pulsar Vela indicates hidden physics around dead stars. When you purchase through links on our site ...

Astronomers have caught a highly magnetic dead star, or "magnetar," in the Milky Way briefly acting like a pulsar, a type of neutron star that rapidly rotates. The magnetar put on its pulsar disguise ...

Astronomers have witnessed a never-seen-before event in observations by ESA’s XMM-Newton spacecraft – a collision between a pulsar and a ring of gas around a neighbouring star. The rare passage, which ...

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 ...

Hiding within the huge catalog of newly found pulsars are several "spider pulsars," or neutron stars that devour their companion stars. When you purchase through links on our site, we may earn an ...

A rapidly spinning neutron star orbits a smaller, helium-rich star very closely. This unique pair formed when a larger star exploded, leaving behind the neutron star which then interacted with its ...
