Webb finds metal-rich gas around Milky Way's black hole Sgr A*

The James Webb telescope found that gas orbiting Sagittarius A*, the Milky Way's supermassive black hole, is rich in metals. Researchers at McGill University's Trottier Space Institute attribute the enrichment to exploding stars that released material into the black hole's surroundings over time.

• Gas around Sgr A* is rich in metals
• Enrichment linked to exploding stars near the black hole
• Observations were made with the James Webb telescope
