A report from the European Southern Observatory (ESO<\/a>):<\/p>\n

Astronomers discover disc around star in another galaxy for the first time<\/a><\/strong><\/p>\n

This artist\u2019s impression shows the HH 1177 system, which is located in the Large Magellanic Cloud, a neighbouring galaxy of our own. The young and massive stellar object glowing in the centre is collecting matter from a dusty disc while also expelling matter in powerful jets. Using the Atacama Large Millimeter\/submillimeter Array (ALMA), in which ESO is a partner, a team of astronomers managed to find evidence for the presence of this disc by observing its rotation. This is the first time a disc around a young star \u2014 the type of disc identical to those forming planets in our own galaxy \u2014 has been discovered in another galaxy.<\/figcaption><\/figure>\n

In a remarkable discovery, astronomers have found a disc around a young star in the Large Magellanic Cloud, a galaxy neighbouring ours. It\u2019s the first time such a disc, identical to those forming planets in our own Milky Way, has ever been found outside our galaxy. The new observations reveal a massive young star, growing and accreting matter from its surroundings and forming a rotating disc. The detection was made using the Atacama Large Millimeter\/submillimeter Array (ALMA) in Chile, in which the European Southern Observatory (ESO) is a partner.<\/p>\n

\u201cWhen I first saw evidence for a rotating structure in the ALMA<\/a> data I could not believe that we had detected the first extragalactic accretion disc, it was a special moment,\u201d<\/em><\/p>\n

says Anna McLeod, an associate professor at Durham University in the UK and lead author of the study published today<\/a> in Nature<\/em>.<\/p>\n

\u201cWe know discs are vital to forming stars and planets in our galaxy, and here, for the first time, we\u2019re seeing direct evidence for this in another galaxy.\u201d<\/em><\/p>\n
