What to know about Webb reveals oxygen-rich dust and water surviving near Milky Way's central black hole

Astronomers using the James Webb Space Telescope have discovered that the evolved star IRS 3 produces oxygen-rich dust and water despite its proximity to the Milky Way's central supermassive black hole. The study, published in Astronomy & Astrophysics, suggests that stars in extreme galactic environments can still contribute essential materials for future stellar and planetary formation.

Why it matters

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*.

Common ground

IRS 3 has reached a stage near the end of its life called the asymptotic giant branch phase.
