NASA has again released a spectacular new picture of our galaxy's violent, super-energised “downtown” on May 28. It is located at a distance of 26,000 light years away.
It's an amalgamation of 370 observations over the past two decades by the orbiting Chandra X-ray Observatory. Chandra was launched in 1999, is in an extreme oval orbit around Earth.
It depicts billions of stars and countless black holes in the centre of the Milky Way. A radio telescope in South Africa also contributed to the image, for contrast.
Astronomer Daniel Wang of the University of Massachusetts Amherst said, he spent a year working on this while stuck at home during the pandemic.
He said that “the picture is a violent or energetic ecosystem in our galaxy's downtown. There are a lot of supernova remnants, black holes, and neutron stars there. Each X-ray dot or feature represents an energetic source, most of which are in the canter.”
His work appears in the June issue of the Monthly Notices of the Royal Astronomical Society.
