Scientists have found another space oddity 400 light-years from Earth: a binary star with three misaligned planet-forming discs.
The record breaking system was the most luminous Gamma-ray binary system to be detected.
If a star dies in a vacuum, and no galaxy is around to see it, did it ever truly live? Astronomers can start asking some pretty existential questions, after discovering that three massive stars went supernova while drifting in the vast darkness between galaxies - lonely deaths hundreds of light-years away from any known system.
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.
Astronomers stumbled upon an "upside-down planet" that offers a new method for studying binary star systems.
