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

Lizzo said as she greeted Henry Ford workers in the unique way that Detroiters do. (If you're unfamiliar or just not from Detroit, look up Detroit artist Tone Tone and the song "What Up Doe," which popularized the phrase.)The video was posted to the hospitals Twitter page, as Lizzo shared a message thanking Henry Ford's #HealthCareHeroes serving on the front lines. 658
