Pierre Auger Observatory
@augerobs.bsky.social
The Pierre Auger Observatory is a hybrid detector, employing independent methods to detect and study the highest-energy cosmic rays. More than 400 scientists from 17 countries make up the International Collaboration in this institution.
Seven (5 early-career) Pierre Auger collaborators presented varied research at the TeV Particle Astrophysics Conference in Valencia (Nov 3-7, 2025). Talks covered ultra-high-energy cosmic-ray composition, photons, neutrinos, and probes of dark matter.
Congratulations!
Congratulations!

In order to preserve the historical memory of the Pierre Auger Observatory captured in newspaper articles, the Observatory's Newspaper Archive opens today, featuring news from 1996 (print and digital versions).
The first Argentine newspaper archive was founded by Mariano Moreno on Sep. 13th, 1810.
