Imagine a star so dense that a teaspoon of its material would weigh as much as Mount Everest, spinning hundreds of times per ...

Hiding within the huge catalog of newly found pulsars are several "spider pulsars," or neutron stars that devour their companion stars. The Fermi gamma-ray space telescope has discovered around ...

Pulsars are neutron stars that can spin as fast as 700 times per second. They blast out beams of radiation from their poles that sweep across space like the beam of a celestial lighthouse.

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, ...

Millisecond pulsars spin far more rapidly than expected for a collapsed star. The best chance to study these neutron stars is to find a black widow system where the pulsar has evaporated and eaten ...

Neutron stars are considered to be the most extreme and exotic celestial objects in the known universe. Created when a massive star runs out of fuel for nuclear fusion and its stellar core ...

Pulsars, those spinning, superdense neutron stars that send powerful "lighthouse beams" of radio waves and light flashing through the Universe, have been "lying about their ages," leading ...

Since pulsars are rotating neutron stars where their magnetic pole sweeps in our direction, we can measure the rate of rotation by timing the radio pulses from a pulsar.

Some massive stars collapse into ultra-dense, rapidly spinning neutron stars called pulsars, which are some of the more powerful and fascinating objects in the cosmos, just behind black holes.

Studying distant objects in space can be tricky for astronomers, especially when those objects begin to do unexpected — and unexplainable — things. Neutron stars … ...

This process, called accretion, causes the neutron star to “spin up” and become a pulsar. But in common envelope evolution, “the companion star is so large that its outer layers engulf the ...
