Astronomers have just uncovered the true nature of what they thought was a regular supernova observed in January. At the time, it looked like a supernova emitting a 5-minute long burst of X-rays. But these X-rays were of a lower energy (known as “soft” X-rays) than expected leading some to believe this was a normal [...]

For the first time, a spacecraft has detected signals from both stars of a binary pulsar system in X-rays. XMM-Newton is watching both stars radiate pulsating X-rays, providing scientist with the perfect laboratory for high-energy physics and a never-ending source of intriguing physical problems. The binary pulsar PSR J0737-3039 was first spotted by astronomers in [...]
