James Webb telescope finds heavy elements near Sagittarius A*, revealing new clues about star formation near the Milky Way's black hole.
Heavy elements found near black hole
The James Webb telescope has detected an unusually high amount of heavy elements in the gas surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way. These elements, which are heavier than hydrogen and helium, are typically produced in stars and during their explosive deaths, such as supernovas.Study published in 2026
A research team led by Nicole Ford published their findings on October 19, 2026, in The Astronomical Journal. The study focused on gas filaments spiraling toward Sagittarius A* and found a significant concentration of these heavy elements.Light from ancient past
The light analyzed by the telescope originated from the galactic center 26,000 years ago, a time when early humans were painting cave walls. This provides a glimpse into the conditions of the Milky Way’s core during the Stone Age.Chemical signatures match nearby stars
The presence of these metals near the black hole suggests that stars and gas in the region formed together. The chemical composition of the gas matches that of several neighboring stars, indicating a shared origin and history.New discovery in black hole environment
The discovery was made along a gas structure known as a minispiral, a feature previously observed near Sagittarius A*. The high concentration of metals in such a location was unexpected and had not been documented before.
