Young sunlike star reveals rapid two-year magnetic cycle

Scientists at the Leibniz Institute for Astrophysics Potsdam (AIP) have uncovered the intricate magnetic heartbeat of a distant star remarkably similar to our own sun—but much younger and more active. This study, part of the “Far Beyond the Sun” campaign, follows nearly three years of ultra-precise observations and sheds new light on how stars like our sun generate their magnetic fields—and how these fields evolve over time.
