This photo of a moon-forming disc around an exoplanet puts Saturn to shame


Scientists have captured an unambiguous image of a moon-forming disc around an exoplanet, the first time such a thing has been imaged outside of our own solar system.

Using the Atacama Large Millimetre/submillimeter Array (ALMA), astronomers honed in on a still-forming solar system 400 light years away after earlier observations of the system determined that a pair of gas giants in the system – similar to our system’s Jupiter-Saturn pairing – were still in the process of formation.
