New observations from the James Webb Space Telescope show that IRS 3, a star near the center of the Milky Way, is losing vast amounts of mass, causing its surrounding envelope to expand continuously.

Near the supermassive black hole at the center of the Milky Way, a mature star is shedding enormous amounts of gas and dust into space. Observations of IRS 3 suggest that this material has created an exceptionally large envelope, and within it astronomers have detected water molecules despite the extreme environment surrounding the galactic center.

The research was led by PD Dr. Florian Peißker of the University of Cologne’s Institute for Astrophysics. Peißker’s group, which participates in the European James Webb Space Telescope (JWST) consortium studying nearby galaxies, investigates the region surrounding Sagittarius A*, or Sgr A*, the supermassive black hole at the center of the Milky Way.
