Webb reveals metal-rich gas around Milky Way's central black hole

The Gas Near Sagittarius A-star is Enriched in Metals, Probably from Supernovae Explosions

The region near Sagittarius A-star, the Milky Way's supermassive black hole, is enriched in metals, although only modestly. The likely cause is supernovae explosions, which synthesize elements heavier than hydrogen and helium. Over time, this metal-rich gas found its way towards the SMBH. The increased metallicity and heat from the supernova affect how fast gas flows into the SMBH.

Webb reveals metal-rich gas around Milky Way's central black hole

The gas orbiting Sagittarius A (Sgr A*), the supermassive black hole at the center of the Milky Way galaxy, is rich in metals, researchers at McGill University's Trottier Space Institute have found. The metal enrichment probably resulted from stars that exploded and released material into the black hole's surroundings over time, they said.

Webb telescope finds metal-rich gas near our galaxy’s central black hole

The James Webb Space Telescope has revealed that gas near the Milky Way’s central black hole contains large amounts of elements heavier than hydrogen and helium. The finding offers new clues about the history of stars and material in the crowded heart of our galaxy. Researchers at McGill University studied gas orbiting Sagittarius A*, the […]
