Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have observed materials streaming away from Herbig Haro 46/47 and a previously unknown jet stream of material flowing away in a different direction.
The image above shows jets of material flowing out of a newborn star (orange, green, pink, and purple). The pink and purple jets have been observed before but the orange and green jets , previously hidden by the surrounding gas and dust, was just discovered by ALMA and shows these streams to be highly energetic.
This zoom sequence starts with a wide view of the southern Milky Way and then closes in on a rich region of dark clouds and young stars in the constellation of Vela (The Sails). One of these dark star-forming clouds features the Herbig-Haro object HH 46/47 where jets from a young star are colliding with the surrounding material. This object was the target of a study using ALMA during the Early Science phase.
