X-rays from NASA’s Chandra Observatory reveal that a fast-moving pulsar in orbit around a massive star punched a hole in a circumstellar disk of material and launched a fragment of the disk outward at a speed of about 40 million miles per hour. X-ray evidence from NASA’s Chandra Observatory suggests that a clump of stellar material has been jettisoned away from the binary system B1259 at incredibly high speeds. The bright source in the center...
