Contest #750 – Owens Valley Radio Observatory, Big Pine, California, USA

On February 17, 2022, CAL FIRE notified the scientists manning the Owens Valley Radio Observatory that they were under a mandatory evacuation because the Airport Fire was barrelling down on the facility. Thankfully, the winds died down and the brave firefighters were able to redirect the fire and eventually get it under control without damage to the OVRO.

One week later on February 25th, Caltech issued a press release which stated, among other things, that

Long-term radio monitoring of a supermassive black hole at the center of a galaxy some 9 billion light years distant appears to show it has a massive unseen partner. The Caltech-led observations were made over a 13-year period by the Owens Valley Radio Observatory in Northern California and reveal that the radio black hole will soon merge with a companion black hole to form a supermassive black hole binary (SMBHB).
