Astronomers have achieved a significant milestone in space exploration by identifying, for the first time, a planet-forming disk around a young star in a galaxy outside our Milky Way.
This remarkable discovery, made in the Large Magellanic Cloud, a neighboring galaxy located 160,000 light-years away, sheds new light on the universal processes of star and planet formation, akin to those in our own galaxy. The system, known as HH 1177, is nestled within a vast gas cloud in the Large Magellanic Cloud. The Atacama Large Millimeter/submillimeter Array (ALMA), the largest astronomical project on Earth comprising 66 antennas in Northern Chile, played a crucial role in this discovery. ALMA’s capabilities as a single radio telescope allowed for this unprecedented observation of celestial phenomena.
