Astronomers have detected the most massive neutron star ever, and it almost shouldn't even exist.Neutron stars are the smallest in the universe, with a diameter comparable to the size of a city like Chicago or Atlanta. They are the leftover remnants of supernovae. But they are incredibly dense, with masses bigger than that of our sun. So think of the sun, compressed into a major city.In the case of the newly detected neutron star, dubbed J0740+6620, it's 333,000 times the mass of the Earth and 2.17 times the mass of the sun. But the star is only about 15 miles across. It's 4,600 light-years from Earth.This is close to the limit of how much mass a compact object can contain before it crushes itself into a black hole.The neutron star itself is rapidly spinning, which is called a pulsar because they send out beams of radio waves from each magnetic pole. The beams mimic the sweeping motion of a lighthouse beam, hence the name "pulsar."Pulsars act like atomic clocks because they regularly pulse, so astronomers can use them to study space and time.The star was detected by the 1098

An independent investigation conducted into a racist photograph on Virginia Democratic Gov. Ralph Northam's 1984 medical school yearbook page could not "conclusively determine the identity of either individual depicted in the photograph.""No individual that we interviewed has told us from personal knowledge that the Governor is in the photograph, and no individual with knowledge has come forward to us to report that the Governor is in the photograph," 468

By several accounts, security was present and conspicuous at the Garlic Festival in Gilroy, California, over the weekend.The Gilroy Police Department had a "compound" on site, the police chief said. Patrons at the family-friendly food festival reported seeing officers on horses and motorcycles.Yet, a 19-year-old, identified by police as Santino William Legan, was able to cut through a back fence and begin shooting people at random. The mayhem Sunday left three people dead and at least 12 injured.It also put a spotlight on soft targets, places like festivals, schools and churches where people often think they can let their guard down and live freely and safely. Another shooting at a festival in New York Saturday that left one dead and 11 injured also emphasized the precariousness of such spaces.Law enforcement experts say that despite heavier security at festivals, schools and churches, there's really little that can be done to prevent attacks from happening."No one would associate the Garlic Festival with an attractive target," said James Gagliano, a CNN law enforcement analyst and retired FBI supervisory agent.Patrons offer different views of festival securityPolice were present all three days of the festival, Gilroy Police Chief Scot Smithee told reporters Monday."We actually create a police compound where we have a command center, a booking area, you know, all the things you would need to run a major operation like this," Smithee said. "The officers are deployed throughout the park and they're assigned to different regions of the park so they're spread out, we don't have officers all in one spot."Christian Swain, whose band 1667
