Zooming on the protoplanetary disc around V883 Orionis 4K Video

Zooming on the young star V883 Orionis. This star is currently in outburst, which has pushed the water snow line further from the star and allowed it to be detected for the first time with ALMA.

This image of the planet-forming disc around the young star V883 Orionis was obtained by ALMA in long-baseline mode. This star is currently in outburst, which has pushed the water snow line further from the star and allowed it to be detected for the first time. The dark ring midway through the disc is the water snowline, the point from the star where the temperature and pressure dip low enough for water ice to form.
