For the first time, long-distance emissions from neutron stars are spotted by scientists in only infrared light. Scientists offer explanations for the mysterious signals coming from nearby pulsar RX J0806.4-4123.
ESA discovered the brightest pulsar ever to be identified by men. The pulsar is a thousand times brighter than previously thought.
In a day and age where zombies can be regularly found on TV, the silver screen, and even in video games, it's easy to argue that they are anything but rare. But what about radioactive and howling space zombies? Peering into the heart of the Milky Way galaxy, that appears to be exactly what one of NASA's impressive space telescopes has found, the details of which are published in a recent study.
Astronomers wielding NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, say that they have found the brightest pulsar ever seen. Pulsars are the dense stellar corpses of a star gone supernovae, but they boast their own kind of life-after-death, and this one seems to be particularly mighty.
The sizzling remains of countless dead stars in our Universe still pulse with some radioactive activity, namely high-energy pulses of gamma rays. Now astronomers and researchers believe they are one step closer to understanding why this stellar phenomenon occurs.
NASA's Fermi Gama-ray Space Telescope recently identified an "exceptional" binary system that not only contains a rapidly spinning neutron star called a pulsar, but also a relatively small yellow star. Interestingly, close examination revealed that this second star serves much like a dance partner for the pulsar, causing it to exhibit some unusual behavior.
