A star-forming region of the Large Magellanic Cloud glows in striking colors in this image captured by ESO's Very Large Telescope (VLT). The region, known as LHA 120-N 180B – N180 B for short – is a type of nebula known as an H II region (pronounced H two ), and is a fertile source of new stars. ] The Large Magellanic Cloud is a satellite galaxy of our Milky Way galaxy, visible mainly from the Southern Hemisphere. At only around 1
Deep within the cloud of the HII region LHA 120-N 180B, MUSE has spotted a jet emitted by a fledgling star – a massive young stellar object – a star in its early stage of evolution. This is the first time that has been observed in visible light outside the Milky Way. Usually, such jets are obscured by their dusty environment, meaning they can only be detected at infrared or radio wavelengths by telescopes such as ALMA. However, the relatively dust-free environment of the Large Magellanic Cloud allows this jet – nicknamed HH 1177 – to be observed at visible wavelengths. At nearly 33 light-years in length, it is one of the longest such jets ever observed.
HH 1177 tells us about the early lives of stars. The beam is highly collimated; that is, it barely spreads out as the travels. Jets like this are associated with the accretion discs of their star, and can have light on how fledgling stars gather matter. Astronomers have found that both high- and low-mass stars launch collimated jets like HH 1177 via similar mechanisms – hinting that massive stars can form the same way as their low-mass counterparts.
