Scientists said that the inside of neutron stars might contain a form of ultradense matter not found elsewhere in the cosmos.
Some neutron stars may contain a 'special type of matter,' according to a new NASA study.These observations from NASA's Chandra X-ray Observatory indicate that the interiors of neutron stars might contain a unique form of ultradense matter not found elsewhere in the cosmos.Neutron stars are the remnants left after massive stars collapse in supernova explosions. They are extremely dense; a teaspoon of neutron star material would weigh about a trillion pounds.
Co-author Clara Dehman, also from ICE, explained, 'More massive neutron stars have more particles, which might trigger special processes causing them to cool more rapidly.'One possible explanation for the rapid cooling is radioactive decay near the star's center, where neutrinos—lightweight particles that travel effortlessly through matter—carry away energy and heat, leading to swift cooling.Another hypothesis suggests the presence of individual quarks within neutron stars.

New simulations reveal hot neutrinos trapped during neutron star collisionsWhen stars collapse, they can leave behind incredibly dense but relatively small and cold remnants called neutron stars. If two stars collapse in close proximity, the leftover binary neutron stars spiral in and eventually collide, and the interface where the two stars begin merging becomes incredibly hot.
