Description
TW Hydrae protoplanetary disc. Atacama Large Millimeter Array (ALMA) image of the protoplanetary disc around the nearby young star TW Hydrae. This image reveals multiple rings and gaps that indicate the presence of emerging planets as they sweep their orbits clear of dust and gas. This Sun-like star is located around 176 light years from Earth in the constellation of Hydra. ALMA is able to observe details hidden by the massive envelope of dust and gas enveloping the star and its emerging planetary system. This image, published in 2016, was obtained using the 870-micrometre ALMA radio band. For a close-up of the central region, see image C030/0158.
