Quark star

A quark star is a hypothetical type of compact, exotic star, where extremely high core temperature and pressure have forced nuclear particles to form quark matter, a continuous state of matter consist

A comparison of the size of quark star candidate RX J1856, based on data from the Chandra X-ray Observatory, to existing models of the theoretical minimum and maximum diameters of neutron and quark stars
Neutron star

A neutron star is the gravitationally collapsed core of a massive supergiant star. It results from the supernova explosion of a massive star—combined with gravitational collapse—that compresses the co
Quark star
…pressure have forced nuclear particles to form quark matter, a continuous state of matter consisting of free quarks. Some massive stars collapse to form neutron stars at the end of their life cycle, as has been both observed and explained theoretically. Under the extreme temperatures and pressures inside neutron…
Image of the Crab Nebula taken by the Hubble Space Telescope. The wind echo of the Crab Pulsar can be seen on the center-right of the image.
Radiation from the rapidly spinning pulsar PSR B1509−58 makes nearby gas emit X-rays (gold) and illuminates the rest of the nebula, here seen in infrared (blue and red).
