A Neutron Star discovered by NASA Astronomers

NASA discovers lonely neutron starA special kind of neutron star has discovered by NASA astronomers. This neutron star has both low magnetic field and no shining partner. A study published in the journal Nature Astronomy and reported that this star was found with the remaining part of a supernova. It is located at least 200,000 light years from Earth. The recent discovery took place using data of Chandra X-ray Observatory of NASA and Southern Observatory VLT (Very Large Telescope) in Chile. NASA issued a statement that at least 10 similar objects have been discovered in the Milky Way galaxy. But, it was the first one found outside our galaxy. Point to be noted that neutron stars are the ultra-dense cores of massive stars and these stars were collapsed and go through a supernova explosion.

The Oxygen-rich supernova remnants such as E0102 are essential for understanding that how massive stars fuse lighter elements into heavier ones before their explosion. These were visible more than a few thousand years after the original explosion. The oxygen-rich remnants have debris ejected from the interior of dead stars. Chandra observations of E0102 have shown that supernova remnant is dominated by a large ring-shaped structure in X-rays and it was linked to the blast wave of the supernova. The new data collected from MUSE (Multi Unit Spectroscopic Explorer) of VLT pointed out a smaller ring of gas expanding too slowly as compared to the blast wave. There is a blue point-like source of X-rays at the center of this ring. The combined data collected from Chandra and MUSE suggest that this source has been considered an isolated neutron star and it was created in the supernova explosion more than two millennia ago.
