The MeerKAT radio telescope in South Africa has painted a picture of the radio emissions of the Milky Way that has revealed new structures. Here’s more from Astronomy Now:
The stunning imagery shows previously known and newly-discovered features, including supernova remnants, huge magnetised radio filaments and the blazing inferno surrounding the 4-million-solar-mass black hole at the core of the galaxy.
The imagery is based on detailed analysis of a survey carried out during the telescope’s commissioning, resulting in a mosaic of 20 observations captured during 200 hours of telescope time. The result is a 100-megapixel mosaic with a resolution of 4 arc seconds.
