NASA wants to know what’s inside a pulsar

Over 2,000 pulsars — first discovered accidentally 50 years ago — are known by scientists today, and while we have learned some facts about these “beacons” in space after studying them for five decades, there is still a lot we don’t know about these collapsed stars. With its recently started NICER mission, NASA hopes to learn a lot more about pulsars, including what’s inside them.
