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

Ten neutron stars found lurking in the Milky Way include cosmic black widows killing stars with "webs" of viscous plasma and ...

Astronomers from the University of Turku in Finland and elsewhere have performed a broadband spectral and timing study of an ...

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 'cosmic lighthouses' that when seen from Earth appear to be flickering stars, but actually consist of exotic stellar remnants called neutron stars.

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 ...

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

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 ...

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.
