Brightest Gamma-Ray Burst of All Time Challenges Element Formation Theories

James Webb Space Telescope observations show no sign of heavy elements. In October 2022, an international team of researchers, including Northwestern University astrophysicists, observed the brightest gamma-ray burst (GRB) ever recorded, GRB 221009A. Now, a Northwestern-led team has confirmed th

Ancient Stars Forged Elements Heavier Than Anything Ever Found in Nature

Stars at the very dawn of time must have been capable of creating elements far heavier than anything that has ever been found naturally occurring on Earth, or at all in the wider Universe.

Cosmic Alchemy: Webb’s First Glimpse Into Heavy Element Creation
Using various telescopes, researchers observed a bright gamma-ray burst, revealing a neutron star merger and detecting the rare element tellurium. These findings, resulting from kilonova explosions, offer deeper insights into element creation, promising more advanced discoveries in the future.

Cosmic Alchemy: Webb’s First Glimpse Into Heavy Element Creation

Webb’s study of the second-brightest gamma-ray burst ever seen reveals tellurium. Under what conditions many chemical elements are created in the universe has long been shrouded in mystery. This includes elements that are highly valuable, or even vital to life as we know it. Astronomers are now
