Astronomers watch as “exoplanet” vanishes before Hubble’s eyes

Exoplanet discoveries are a dime a dozen – but we don’t see many being de-discovered. Now, an exoplanet observed by Hubble for 10 years has apparently vanished without a trace, leading astronomers to suggest it may never have been a planet at all.
