A composite image of the HD 142527 binary star system from data captured by the Atacama Large Millimetre/submillimetre Array shows a distinctive arc of dust (red) and a ring of carbon monoxide (blue and green). The red arc is free of gas, suggesting the carbon monoxide has frozen out, forming a layer of frost on the dust grains in that region. Astronomers speculate this frost provides a boost to planet formation. Release date: February 13, 2016. | |
