Using NASA's X-ray observatory "Chandra", astronomers conducted an X-ray study of the movement of the residual supernova SNR 0509-67.5.

The remnants of the supernovas are diffusely expanding structures that were created by the supernova explosion, and they contain material that was thrown out of the exploded star and expanding as a result of the explosion, as well as other interstellar material that was taken away by the shock wave from the supernova.

SNR 0509-67.5 is the remainder of the supernova type Ia in the Great Magellan Cloud and was detected in the X-ray survey using the Einstein Observatory. Previous observations of this SNR showed that it was about 310 years old. According to the Gregorian calendar, this year was a temple year.

A group of astronomers studied the expansion process of SNR 0509-67.5 and analysed the latest data on the object's own motion, collected in 2020 with the help of the Chandra Observatory.

Scientists have measured the diameter of SNR 0509-67.5 using radial profiles along six areas that cross the geometric centre of the residues and are divided into 30 degrees. New data compared to previous data of the Handra received by scientists in 2000 and 2007. The measured change in diameter of SNR 0509-67.5 in six directions gave an average expansion rate of just over 6,120 km/s.

Research on supernova residues is important for astronomers because they play a key role in the evolution of galaxies, dispersing the heavy elements that result from the supernova explosion, and they also provide the energy needed to heat the interstellar environment. SNR is considered to be responsible for accelerating the galactic cosmic rays.
