Caption: Protoplanetary disc around V883 Orionis, Atacama Large Millimeter Array (ALMA) image. V883 Orionis is a protostar, 1350 light years from Earth, in the constellation of Orion. As a newly formed star, it is currently in outburst mode which affects the structure of the protoplanetary disc. The radiation from the star has pushed a marker called the water-snow line further from the star, allowing it to be detected for the first time. This dividing line shows as the dark ring midway through the disc. This is the point where the temperature and pressure are the right level for water-ice to form. This tipping point affects the type of planets that form, and their habitability. For a diagram of this process, see image C035/6741. Image published in 2016.
