Astronomers will go to great lengths for science. Recently, dozens of astronomers had the misfortune of traveling to one of the most tempting locales in the southwestern U.S.—Las Vegas. But they weren’t there for the city’s bright lights—they were there to observe the very dim light of a star thousands of light-years away. And what they specifically wanted to see was the light from that star blink out for a few seconds. That lack of light provided the exact data they needed to help them determine the size of Eurybates, one of the Trojan asteroids that will be the focal point of NASA’s Lucy mission.
