Here are seven of the most fascinating exoplanets discovered or dramatically redefined in recent years. BD+05 4868 Ab: A planet literally evaporating away Few exoplanets are as dramatic as BD+05 4868 Ab. WISPIT-2 b: Watching a planet being born Most exoplanets are discovered long after they have formed. Located within its star’s habitable zone, the super-Earth has been studied extensively by the James Webb Space Telescope for signs of atmospheric chemistry that could hint at biological activity. With the James Webb Space Telescope, next-generation ground observatories, and future missions on the horizon, these seven worlds are unlikely to remain the most astonishing for long.
