Everything you ever wanted to know about V1647 Ori and McNeil's Nebula

 
An artist's impression of what might be happening behind the thick dust disc surrounding the young Sun-like star V1647 Ori. X-ray observations by ESA's XMM-Newton, NASA's Chandra and Japan's Suzaku space observatories have probed the interior of the dust disc to find a rapidly-rotating star spinning with a period of one day. At 80 per cent the mass of our Sun and with a diameter approximately four times larger, spinning at this rate nears break-up speed for a star of this size. The data also suggest that matter is accreting onto the stellar surface in two pancake-shaped hotspots located on opposite sides of the star, in which the matter heats up and the high temperature plasma is confined.

The fastest moving pulsar ever seen?

Researchers using three different telescopes – NASA's Chandra X-ray Observatory and ESA's XMM-Newton in space, and the Parkes radio telescope in Australia – may have found the fastest moving pulsar ever seen.
