For many years, the observatory in Sunspot, New Mexico, did its job without much fanfare. Instruments up there, on the 9,200-foot Sacramento Peak, watched the Sun—the sort of star you yourself are not supposed to look at through a telescope. 

In early September 2018, though, Sunspot Solar Observatory broke into the national consciousness, and not for a stellar scientific discovery. Instead, the facility made headlines because it and the small surrounding town had been evacuated, because, rumors said, it had been shut down by the FBI.
