The Vera C. Rubin Observatory sits on its mountain peak in Chile during observation activities in April 2025. The observatory will soon begin real-time nightly monitoring of the entire Southern Hemisphere sky. On Feb. 24 the observatory successfully sent out 800,000 public alerts of changes in the night sky. The alerting system is eventually expected to produce seven million alerts per night.
