, but those comets must’ve gotten their water from somewhere. Protoplanetary discs like V883 Orionis are filled with accreted dust and rock, as well as molecules locked away by the frigid temperatures of space.Image“Most of the water in planet-forming discs is frozen out as ice, so it’s usually hidden from our view,’’ said
co-author Margot Leemker, a researcher at Leiden Observatory in the Netherlands, in a European Southern ObservatoryV883 Orionis made for a particularly good observational target because a recent outburst of energy from the star warmed the disc, causing water in the disc to jump from a solid state to its gaseous state , making it relatively easy for ALMA to spot it.
In total, the team found that V883 Orionis contains at least 1,200 times the water Earth has in all its oceans. The team intends to make further observations with the
