Pulsars are rotating neutron stars that emit radiation, which is seen from Earth as a series of highly regular pulses. Anomalous x-ray pulsars (AXPs) are not, however, powered like most pulsars. AXPs ...

Dago de Leeuw, a physicist at Philips Research Laboratories in the Netherlands, leads a team of physicists recognized for their pioneering research in plastic electronics. De Leeuw and colleagues from...
A supernova explosion marks the death of a certain type of star. During the evolution of these stars, nuclear reactions take place at their cores, creating light elements like hydrogen and helium. Hea...
The black hole is around 600 light years from the centre of galaxy M82. “This black hole might eventually sink to the centre of the galaxy where it may grow to become a supermassive black hole&#...

The Rumba and Tango satellites were sent into space on board a French-Russia launcher. Over the next week they will rendezvous with the Salsa and Samba satellites that were launched on July 16. The fo...
Pulsars are rotating neutron stars, and are the collapsed cores of supergiant stars that have exploded as supernovae. They are extremely dense, typically 20 km across but with masses a million times g...

Ulysses was launched to make continuous measurements of the solar wind, a steady stream of ionized particles that flows outwards from the star. In 1998 Pete Riley and colleagues from Los Alamos Nation...
Charles Lindsey of the Solar Physics Research Corporation in Arizona and Douglas Braun of Northwest Research Associates in Colorado used data from a Doppler imager on the Solar Heliospheric Observator...
The team claim to have evidence for: an thin outer layer that is hot; a warm middle layer that is also optically thick; and a “cold” inner layer. The similarity of these layers to that of ...
