Jet trail nebula

Using the NASA Rossi X-ray Timing Explorer (RXTE) satellite, a team of astronomers have discovered an object predicted, but never seen before - a 'jet trail' nebula. Team leader Dr Klaas Wiersema of the University of Leicester will present the discovery on Wednesday 22nd April at the European Week of Astronomy and Space Science conference at the University of Hertfordshire.
The RXTE satellite has been scanning the centre of our galaxy every few days for the last years, searching for variable X-ray sources. Through these scans it has found a multitude of varying X-ray sources, most of which are thought to be X-ray binaries. These systems consist of a compact star (a neutron star or black hole) that pulls material away from a 'normal' companion star. This material forms hot disks, which emit X-rays. X-ray binaries are also known to spout jets of gas at velocities very close to the speed of light.
