Unique stellar system gives Einstein a thumbs-up

Taking advantage of a unique cosmic coincidence, astronomers have measured an effect predicted by Albert Einstein's theory of General Relativity in the extremely strong gravity of a pair of superdense neutron stars. The new data indicate that the famed physicist's 93-year-old theory has passed yet another test.

Europe to build state of the art laboratory

One of the great ongoing challenges of astrophysics, to find out how stars evolve and die, is to be tackled in an ambitious European research programme. This will involve studying in the laboratory over 25 critical nuclear reactions using low-energy stable beams of ions, in order to understand stellar evolution.

Supernova Imposter Goes Supernova

In a galaxy far, far away, a massive star suffered a nasty double whammy. On Oct. 20, 2004, Japanese amateur astronomer Koichi Itagaki saw the star let loose an outburst so bright that it was initially mistaken for a supernova. The star survived, but for only two years. On Oct. 11, 2006, professional and amateur astronomers witnessed the star actually blowing itself to smithereens as Supernova 2006jc.

First astrophysical results with AMBER/VLTI

The AMBER instrument installed at the Very Large Telescope (VLT) of the European Southern Observatory (ESO) combines the light from three 8.2 meter telescopes, making the VLT the world's largest optical telescope, with a total mirror surface larger than 150 m2 and a maximum telescope separation greater than 130 m. Two years after installation, the first astrophysical results are blossoming. They are being published this week as a special feature in Astronomy & Astrophysics.
