A five star, doubly-eclipsing star system

Astronomers at the Open University have discovered the first quintuple star system containing two eclipsing binary stars. Details of the five star system, the first of its kind to be found, will be presented by Marcus Lohr ...

Neptune's badly behaved magnetic field

Combining 26-year old data with supercomputer simulations, a team of scientists at Imperial College London have modelled Neptune's magnetic field in detail for the first time. The researchers find that the furthest planet ...
