The instrument that spots killer asteroids and star-eating black holes
From CNN, Feb. 16, 2019: Fermilab scientist Don Lincoln discusses the Zwicky Transient Facility, a massive sky-survey instrument designed to scan the heavens and look for “transients” or things that brighten unexpectedly. When the instrument sees a change, alerts go out to other astronomers subscribed to the service, who can then use even more powerful telescopes to study the transient event in detail. Even the public can get a daily summary of the previous night’s happenings.
