Nebula 25 thousand years from Earth turned out to be a young supernova remnant

Astronomers have carried out detailed X-ray observations of the recently discovered supernova remnant G53.41 + 0.03. The research is detailed in an article posted on the arXiv preprint server.

Remnants of supernovae – supernova remnant, SNR – nebulae that appeared due to the catastrophic explosion of a star that occurred many tens or hundreds of years ago and its transformation into a supernova. They consist of ejected matter from the explosion and other interstellar material that was carried away by the shock wave from the supernova.

Studies of supernova remnants are important to astronomers because they play a key role in the evolution of galaxies, scattering heavy elements from supernova explosions and providing the energy needed to heat the interstellar medium. SNRs are also thought to be responsible for the acceleration of galactic cosmic rays.

Object G53.41 + 0.03 was confirmed as a supernova remnant in 2018 by analyzing data from the LOFAR (LOw Frequency ARray) observatory. It turned out that the supernova remnant is relatively young and is estimated to be about 24,450 light-years from Earth.

A group of astronomers led by Vladimir Domchek from the University of Amsterdam, Netherlands decided to closely study the nebula using ESA’s XMM-Newton spacecraft.

The study identified three unique regions of the supernova remnant. They show differences in brightness and plasma characteristics.

In addition, spectral analysis showed that G53.41 + 0.03 appeared from 1,000 to 5,000 years ago, which confirms the relatively young age of the nebula.
