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&#...

“Solar activity has been increasing for the past three or four years, and now Ulysses has started observing much more disturbed conditions at increasing solar latitudes,” explains Andre Ba...

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 ...
Black holes are usually detected by the effects of their vast gravitational field on the orbits of nearby astronomical objects such as stars. Naked black holes have no such material near them making i...
Confirmation that the universe is flat – expanding at just the right rate not to collapse – came from measurements of ripples in the cosmic background radiation left over from the big bang...
Inside a pulsar the neutrons are thought to decay into protons and electrons, which are then accelerated by the pulsar’s powerful magnetic field. Since protons and electrons are charged particle...
