Evryscope

The closest exoplanet is Proxima Centauri b — just four and a quarter light-years away. Its parent star, Proxima Centauri, is less than one percent as bright as the Sun. Every once in a while, though, it unleashes a huge outburst of energy and particles. And more than two years ago, astronomers saw the most powerful one yet.
Such “superflares” should happen several times a year. And that’s bad news for the planet. If it has an atmosphere, the flares could strip away any ozone atop it, bathing the planet in deadly ultraviolet light. They might even strip away the atmosphere itself.
The flare was observed with Evryscope — a set of a couple of dozen small telescopes in Chile. They’re combined into a single unit that looks like the top of a Star Wars droid.
The system takes a picture of the entire southern sky every two minutes. That allows it to monitor millions of stars. It looks for the stars to flare up. It also searches for exoplanets — looking for a star to grow a tad fainter as a pl
