Visualisation of the warped disc around the young star MWC 758, with warping exaggerated by a factor four to make it visible. Both panels show properties of the disc inferred from CO emission. On the left-hand side, we see deviations in the line-of-sight velocity from the expected rotation if the disc were flat. The variations in velocity can be used to infer the warp structure. On the right-hand side we see variations in the gas temperature, from which we can see evidence of shadowing in areas of the disc. Credit: A. Winter
New ALMA observations reveal that the discs where planets form are often slightly warped, challenging long-held assumptions and offering clues about the subtle misalignments seen in our own Solar System.
Astronomers using ALMA have discovered that planet-forming...
