This image showcases the location of the highly evolved star IRS 3, which is located just 0.55 light-years from Sagittarius A*, the Milky Way galaxy's central supermassive black hole. The images show a progressinvely closer view of the region using ground- and space-based data. An international team of astronomers have discovered that dust and water can form and survive surprisingly close to this supermassive black hole. The observations reveal that the evolved star IRS 3 continues to enrich its surroundings with newly formed material despite the intense radiation environment around Sagittarius A*.
