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.
Central neutron star at the heart of the Crab Nebula 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). A neutron star is the collapsed core of a massive supergiant star.
The Crab Pulsar (PSR B0531+21 or Baade's Star) is a relatively young neutron star. The star is the central star in the Crab Nebula, a remnant of the supernova SN 1054, which was widely observed on Earth in the year 1054. [8] [9] [10] Discovered in 1968, the pulsar was the first to be connected with a supernova remnant. [11]
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. [3] In the cores of these stars, protons and electrons combine to form neutrons. [2] Neutron stars can be classified as pulsars if they are ...
A star in a binary star system has collapsed to a neutron star. It begins to gain material from its companion star (known as "accretion"). The infalling matter causes it to speed up and begin emitting high energy radiation, eventually forming a pulsar rotating at up to 1000 times a second.
Neutron star: Neutron stars are stellar remnants produced when a star of around 8–9 solar masses or more explodes in a supernova at the end of its life. They are usually produced by stars of less than 20 solar masses, although a more massive star may produce a neutron star in certain cases. [2] 4U 1820-30: 9.1 Pulsar [3] PSR B0943+10: 10 or 2 ...
Zooming in on the very faint neutron star RX J1856.5–3754 Hubble image of RX J1856.5−3754—the first direct observation of an isolated neutron star in visible light. RX J1856.5−3754 is thought to have formed in a supernova explosion of its companion star about one million years ago and is moving across the sky at 108 km/s.
A neutron star is the ultra-compact remnant of a massive star which exploded as a supernova. Neutron stars have a mass bigger than the Sun , yet are only a few kilometers across. These extremely dense objects rotate on their axes , producing focused electromagnetic waves which sweep around the sky and briefly point toward Earth in a lighthouse ...
