Man har funnit en spännande millisekund-pulsar i hjärtat av ett trippelsystem av stjärnor.
"The millisecond pulsar, PSR J0337+1715, spins nearly 366 times per second. Like a lighthouse, it emits beams of radio waves with each spin. One of the other two stars in the system is a white dwarf star in a 1.6-day orbit. The other star is also a white dwarf in a much-larger 327-day orbit. The entire system – 4,200 light-years from Earth – is packed into a space smaller than Earth’s orbit of our sun"
