    Description“Until now, we used to discover a few hundred to a few thousand transients per year,” says Or Graur (University of Portsmouth, UK). “Going from that to 800,000 alerts per night is a sea change.”

    “Objects that used to be rare will become commonplace, and even rarer objects, that could not have been discovered with the previous surveys, will start popping up,” Graur says. “In other words, the chance of discovering brand-new objects and phenomena is very real.”
