Telescope VLT observed the jet from the young star in another galaxy

Its length is 33 light years.

Astronomers using the very large telescope VLT have been able for the first time to see a jet from a young star in the optical range in another galaxy. He was one of the longest known jets today and essentially throughout its length.

The large Magellanic Cloud is a dwarf galaxy companion of the milky Way and we see it mostly in the sky of the southern hemisphere. Its distance is estimated at about 160 thousand light years, it is considered a transition type between dwarf spiral and irregular galaxies and is the fourth largest mass among the galaxies of the Local group. Its proximity and the fact that a single spiral arm of the galaxy observed flat, allow to trace the evolution of the galaxy and its stellar populations (in particular, to trace star formation), informs Rus.Media.

The nebula LHA 120-N 180B, which is located in the Large Magellanic Cloud, is an HII region in which there are active processes of star formation. For the ionization of gas clouds and their structure, resembling blisters, responsible massive stars that have recently formed. A new image of the nebula obtained by the receiver MUSE (Multi Unit Spectroscopic Explorer) is installed on the telescope VLT (Very Large Telescope),in the inner part of the nebula was able to discern an unusual object that was the subject of Herbig-Haro HH 1177.

The mass of an object is 12 times greater than the mass of the Sun, he is a young star surrounded by the accretion disc, and generates bipolar high-speed narrow streams of matter (jets), which, spreading, may be faced with surrounding gas and dust clouds. Typically, the jets are hidden from the observer dust clouds, but in the case of HH 1177 was the first to observe the jet in the optical range in another galaxy, this is due to the properties of the interstellar medium in the galaxy. The observed jet was one of the longest known to date, its length is 33 light years.
