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.

Very interesting, Jac!

I also find it notable that the massive protostar appears to be fed by a much larger disk of material. But the protoplanetary disk itself is rotating another way than the larger disk.

This reminds me of the rotation of the Solar System vs. the rotation of the Milky Way:

Looks like the (false color) red and blue structures that I thought were parts of a rotating disk may instead be jets emitted by the protostar!
