X-ray, Infrared, and Illustrations of GRB 230906ACredit: X-ray: NASA/CXC/Penn State Univ./S. Dichiara; IR: NASA/ESA/STScI; Illustration: ERC BHianca 2026 / Fortuna and Dichiara, CC BY-NC-SA 4.0; Image Processing: NASA/CXC/SAO/P. Edmonds
These graphics depict the likely discovery of a collision between two neutron stars, made by Chandra and other telescopes, in a tiny galaxy buried in a huge stream of gas. This is the first time that a neutron star collision has been spotted in such a setting. Two artist’s illustrations — one showing a full field view and the other a close-up side view — depict what astronomers think is happening in the event known as GRB 230906A. First picked up by Fermi in September 2023, the event was then observed by Swift to provide a more accurate position followed by observations with Chandra and Hubble. The Chandra data gave the researchers an even more accurate position for the GRB, showing it is likely located in a tiny galaxy seen in a Hubble image.
