Astronomers have spotted the highest-energy outburst of light from a pulsar ever seen. The discovery could indicate new physics around these incredibly dense, rapidly spinning dead stars. The team, ...

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 ...

Nearly 1,000 light-years from where you're sitting lies a spinning, highly magnetized neutron star that is so dense, a tablespoon of it equals something like the weight of Mount Everest. It's an ...

This image shows the Vela pulsar wind nebula. Light blue represents X-ray polarization data from NASA’s Imaging X-ray Polarimetry Explorer. Pink and purple colors correspond to data from NASA’s ...

When a massive star dies, it leaves behind a dense core called a neutron star. Many of these exotic suns spin rapidly, sending out beams of radiation like lighthouses, and these are called pulsars.

Star bright is an understatement. A dead star known as the Vela pulsar redefined hit Earth with a blast of energy so powerful that scientists are at a loss to explain it, according to a new study ...

Using NASA’s orbiting Chandra X-ray Observatory, astronomers have captured stunning views of a twisting column of x rays whipping around a pulsar. Propelled by voltages 100 million times more powerful ...

Gérard Grisey (1946-98) first heard the deep sound of the cosmos in 1985, in Berkeley, Calif. There, the French composer associated with the spectralist school met astrophysicist Joe Silk, who played ...

An X-ray movie of the Vela pulsar, made from a series of observations by NASA's Chandra X-ray Observatory, reveals a spectacularly erratic jet that varies in a way never seen before. The jet of ...
