HD 142527 star. Optical image showing the disc of gas and cosmic dust around the young star HD 142527,which lies in the constellation Lupus. Astronomers using the Atacama Large Millimetre/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. Seen here: dust in the outer disc (red),dense gas in the streams flowing across the gap,as well as in the outer disc (green),diffuse gas in the central gap (blue). The gas filaments can be seen at three o'clock and ten o'clock positions,flowing from the outer disc towards the | |
