This amateur astronomer may be the world ’s top supernova hunter

For Koichi Itagaki, it was just another evening of supernova hunting. After his usual 7 p.m. dinner with his wife, he drove to his private observatory in the hills above his home in Yamagata, Japan, 290 kilometers north of Tokyo. He set out treats for the only visitors he allows on his celestial patrols: a stray cat he calls Nora and the raccoon dogs that warily approach from the surrounding forest. He then took a seat within his “headquarters,” a cozy hut equipped with a bed, minifridge, microwave—and a dozen monitors used to control seven telescopes at three locations across Japan. On clear nights, each telescope runs through a routine, focusing on one of the approximately 1000 galaxies Itagaki monitors for two 15-second exposures before swiveling to the next target. On this night, clouds blanketed most of the country, leaving a clear view only for his two telescopes in Okayama, 700 kilometers to the southwest. But as the clock ticked into the early morning of 20 May, clouds drifted over Okayama, too. Itagaki called it a night and drove home, leaving the telescopes on automatic in case the weather cleared. It did. The next morning he had scanned the night’s images for just 5 minutes when he spotted a new, bright object in a spiral arm of the Pinwheel galaxy, 21 million light-years away. “It was so bright, I thought there was no way this object could have been missed,” he says. To his surprise, he was the first to post the news to the Transient Name ...
