A Tour of XJ1500+0154
Every so often, an object will pass too close to a black hole and be ripped apart by its intense gravitational forces. (2017-02-06)


IGR J11014-6103 in 60 Seconds

View/Listen
Narrator (April Hobart, CXC): Has the speediest pulsar been found? That's the question that astronomers are asking after three different telescopes looked at the pulsar known as IGR J11014-6103. This pulsar was found racing away from a supernova remnant located about 30,000 light years from Earth. An image from the European Space Agency's XMM-Newton satellite shows a glowing debris field in X-rays. This is the remains of a massive star that exploded thousands of years before. Using NASA's Chandra X-ray Observatory, researchers were able to focus their attention on a small, comet-shaped X-ray source outside the boundary of this supernova remnant. It appears that this object, thought to be a rapidly spinning, incredibly dense star – which astronomers call a "pulsar" -- was ejected during the supernova explosion. Researchers calculate that this pulsar may be dashing away from the supernova at speeds of about 6 million miles per hour. If this result is confirmed, it would make this pulsar the fastest ever seen.
