Astronomers mapped the surface of a neutron star for the first time


Astronomers mapped the surface of a neutron star for the first time Astronomers mapped a neutron star, thanks to NASA’s Neutron Star Inner Composition Explorer (NICER), an X-ray telescope at the International Space Station.

For the first time, NASA was able to map the entire surface of a neutron star. Astronomers said that the mass of the neutron star, which is about 25 km in diameter, is 1.5 times higher than the mass of the Sun.

For decades, scientists have been trying to understand exactly what neutron stars are. In the simplest model, a neutron star has a strong magnetic field very similar to a household magnet. Due to the strong magnetic field, the neutron star, called the J0030, can rotate 205 times per second.

Astronomers say that the magnetic fields of the neutron star are more complex than traditional bipolar models, with the map that has been uncovered through the NICER X-ray telescope, which lasted for nearly 10 years.

A NICER’s unique X-ray measurements have enabled us to make the most accurate and reliable calculations of the size of a neutron star to date with less than 10% uncertainty. The entire NICER team has made significant contributions to fundamental physics that cannot be explored in terrestrial laboratories. ”
