ESOcast 229 Light: Planet-forming Disc Torn Apart by its Three Central Stars

A team of astronomers used ALMA and ESO telescopes to study a peculiar system, GW Orionis, and to identify the first direct evidence that groups of stars can tear apart their planet-forming disc, leaving it warped and with tilted rings. This video provides a summary of the findings, showcasing stunning observations and animations of GW Orionis.

The video is available in 4K UHD.
