Location of Star IRS 3 close to Milky Way galaxy's central black hole | Webb Telescope

These images show the location of the highly evolved star IRS 3. It is located just 0.55 light-years from Sagittarius A* (Sgr A*), the Milky Way galaxy's central supermassive black hole.

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*.

The data in this image were taken with Webb programs #1939 (J. Lu), #3571 (F. Yusef-Zadeh), #2491 (N. B. Sabha), and #2075 (C. Chan).
