The findings were published in Nature Astronomy and are from the National Science Foundation-funded NANOGrav Physics Frontiers Center. Astronomers at the West Virginia University were using the Green Bank Telescope in Pocahontas County to observe the star which has been titled J0740+6620.

J0740+6620 is a rapidly spinning pulsar star that harbors 2.17 times the mass of the Sun which is staggering 333,000 times the mass of the Earth. What is most interesting though is that this neutron star is only 20-30 kilometers across, breaching the known limits of how massive and compact a single object can be without converting itself into a black hole.

Jak's love for technology, and, more specifically, PC gaming, began at 10 years old. It was the day his dad showed him how to play Age of Empires on an old Compaq PC. Ever since that day, Jak fell in love with games and the progression of the technology industry in all its forms. Instead of typical FPS, Jak holds a very special spot in his heart for RTS games.
