Disc of gas around HD 142527

This artist’s impression shows the disc of gas and cosmic dust around the young star HD 142527. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have seen vast streams of gas flowing across the gap in the disc. These are the first direct observations of these streams, which are expected to be created by giant planets guzzling gas as they grow, and which are a key stage in the birth of giant planets.

TRY A LITTLE TENDRILNESS  Observations made with the Atacama Large Millimeter/Submillimeter Array (ALMA) telescope of the disc of gas and cosmic dust around the young star HD 142527, showing vast streams of gas flowing across the gap in the disc; the bottom image is an artist’s rendition of same. These are the first direct observations of these streams.  HD 142527 is about 450 light years away from Earth.  (Images: ALMA / M. Kornmesser / ESO via Space.com)
