It can also be created for brief moments in particle colliders on Earth, such as CERN’s Large Hadron Collider.

Within a neutron star—the remains of an exploded, middle-weight star—pressures climb a billion billion times higher than in the sun's core.

An artist’s conception of a massive neutron star.

Image credit: L. Calçada / ESO.Neutron stars, which are the result of a supernova explosion, are the smallest and densest stars in the Universe.While these objects typically have a radius of about 10 km, they average between 1.4 and 2.2 solar masses.Inside neutron stars, atomic matter is known to collapse into immensely Up until now, it has remained unclear whether inside the cores of “Confirming the existence of quark cores inside neutron stars has been one of the most important goals of neutron star physics ever since this possibility was first entertained roughly 40 years ago,” said senior author With large-scale simulations run on supercomputers unable to determine the fate of nuclear matter inside neutron stars, Dr. Vuorinen and colleagues proposed a new approach to the problem.They realized that by combining recent findings from theoretical and nuclear physics with astrophysical measurements, it might be possible to deduce the characteristics and identity of matter residing inside neutron stars.They found that matter inside the cores of the most massive stable neutron stars bears a much closer resemblance to quark matter than to ordinary nuclear matter.Their calculations indicate that in these stars, the diameter of the core identified as quark matter can exceed half of that of the entire neutron star.However, there are still many uncertainties associated with the exact structure of neutron stars.“There is still a small but nonzero chance that all neutron stars are composed of nuclear matter alone,” Dr. Vuorinen said.“What we have been able to do, however, is quantify what this scenario would require.”“In short, the behavior of dense nuclear matter would then need to be truly peculiar.”“For instance, the speed of sound would need to reach almost that of light.” An artist's concept of the layers of a neutron star, including the quark core

Michael has always been fascinated by space, technology, dinosaurs, and the weirder mysteries of the universe. In some cases, the quarks may even make up more than half of the neutron star itself.To get to this conclusion, the team calculated the “equation of state” of matter in neutron stars.

View 1 Image 1 / 1. A neutron star is the collapsed core of a giant star, which before collapse had a total mass of between 10 and 29 solar masses.Neutron stars are the smallest and densest stars, excluding black holes and hypothetical white holes, quark stars, and strange stars. An artist's concept of the layers of a neutron star, including the quark core Astrophysicists have found evidence of a strange substance called quark matter at the heart of compact stars.

Massive neutron stars have sizable quark-matter cores, according to a study published in the journal Nature Physics. For instance, the speed of sound would need to reach almost that of light.”More data on neutron stars – which is pouring in all the time – will help refine these calculations even further.
