A quackery of astroquarks takes a close look at neutron stars thanks to observations from the NICER observatory on the International Space Station and some clever scientific modeling that reveals these rapidly spinning stellar remnants are not too soft, not too stiff, but just the right amount of squeezable.

Get the answers to all this and more on Walkabout the Galaxy.
