Summary

Story summary

Scientists at the University of Chicago are analyzing data from the Payload for Ultrahigh Energy Observations (PUEO) mission, which launched on December 20, 2025.
The NASA balloon operated for 23 days over Antarctica, searching for high-energy neutrinos linked to cosmic events like black holes.
PUEO features 96 radio antennas to detect signals from neutrino collisions with ice.
After landing near the South Pole on January 12, 2026, researchers retrieved a data recorder containing 50 to 60 terabytes of information.
Results from the analysis are anticipated in about a year, potentially revealing insights into extreme cosmic phenomena.
