Australian Commonwealth Scientific and Industrial Research Organization (CSIRO) announced on January 17 that researchers from Macquarie University in Australia and the National Institute of Astrophysics (INAF) in Italy, using CSIRO’s radio telescope, announce that they have produced the most detailed radio telescope. Picture ever of a supernova remnant in the Milky Way.

As part of the PEGASUS and EMU observational projects using two radio telescopes owned and operated by CSIRO, ASKAP and Murriyang, researchers have surveyed a large region of the Milky Way’s plane. This image was first published as a collage of data obtained from these surveys.

It is estimated that the Milky Way contains many more supernova remnants than is currently observed, but no telescope has the sensitivity to detect them.

Andrew Hopkins, Macquarie University Professor, lead scientist for the EMU project, said: “This new image clearly shows a region of the Milky Way that can only be seen with radio telescopes. While only seven supernova remnants have been found, these images reveal even more remnants. 20 possible supernovae.

“Ultimately, we will have an unprecedented image that is 100 times larger than this image and captures almost the entire Milky Way,” he said.
