Water ice turned to gas in V883 Ori

V883 Ori is a unique protostar whose temperature is just hot enough that the water in its circumstellar disk has turned to gas, making it possible for radio astronomers to trace the water’s origins. New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) have provided the first confirmation that the water in our Solar System may come from the same place as the water in disks surrounding protostars elsewhere in the Universe: the interstellar medium.
