The Neutron Star Interior Composition ExploreR (NICER) is a NASA telescope on the International Space Station, designed and dedicated to the study of the extraordinary gravitational, electromagnetic, and nuclear physics environments embodied by neutron stars, exploring the exotic states of matter where density and pressure are higher than in atomic nuclei.
Pressure increases accordingly, from about 3.2 × 10 31 Pa at the inner crust to 1.6 × 10 34 Pa in the center. [26] A neutron star is so dense that one teaspoon (5 milliliters) of its material would have a mass over 5.5 × 10 12 kg, about 900 times the mass of the Great Pyramid of Giza.
Zooming to RX J1856.5−3754 which is one of the Magnificent Seven and, at a distance of about 400 light-years, the closest-known neutron star. Neutron stars are the collapsed cores of supergiant stars. [1] They are created as a result of supernovas and gravitational collapse, [2] and are the second-smallest and densest class of stellar objects ...
Astronomers have found evidence that a neutron star exists at the centre of the only exploding star – supernova – visible to the naked eye in the last 400 years, solving a 30-year-old mystery.
By Will Dunham. WASHINGTON (Reuters) - When a star up to 20 times the mass of our sun exploded in a nearby galaxy, the blast was so violent that it was visible to the naked eye from Earth's ...

PSR J0952–0607 is a massive millisecond pulsar in a binary system, located between 3,200–5,700 light-years (970–1,740 pc) from Earth in the constellation Sextans. [6] It holds the record for being the most massive neutron star known as of 2022, with a mass 2.35 ± 0.17 times that of the Sun—potentially close to the Tolman–Oppenheimer–Volkoff mass upper limit for neutron stars.
A mysterious radio blast from space detected in 2022 originated in the magnetic field of an ultra-dense neutron star 200 million light years away.. Known as fast radio bursts, or FRB, such brief ...
