Exomoons represent an oustanding challenge in modern astronomy. The quest for their detection has been a topic central to Cool Worlds' mission and methods developed a decade ago have largely guided that effort. But after years of trying, we have been revisiting these methods and have an exciting breakthrough to share with you all a new hope for finding exomoons.
