Astronomers Release Unprecedented Radio Image of Milky Way’s Center astronomy space science
, the 4.3-million-solar-mass black hole that lurks in the center of our Milky Way Galaxy, 25,000 light-years from Earth.
“At a distance of only 26,745 light-years, the region presents astronomers with a unique opportunity to study a diverse range of energetic astrophysical phenomena, from stellar objects in extreme environments, to the supermassive black hole and star-formation driven feedback processes that are known to influence the evolution of galaxies as a whole.”
The work represents the culmination of 3 years of detailed analysis of a survey conducted during the MeerKAT’s commissioning phase.of a pair of giant radio bubbles, evidence of an explosive outburst from the heart of our Galaxy several million years ago. The data were consistently processed to deliver an angular resolution of 4 seconds of arc — the angle subtended by a tall person at a distance of 100 km; or by the width of a fine human hair held at arm’s length — resulting in a 100 megapixel image.
“I’ve spent a lot of time looking at this image in the process of working on it, and I never get tired of it,” Dr. Heywood said.
