Herbig-Haro 34 object

Herbig-Haro 34 object (HH 34) is located in the Orion nebula, a broad star formation region that is located to the south of the belt of this famous hunter in the Greek mythology.

This object is the product of the interaction between the jet emitted by a very young star, or protostar, and the interstellar medium.

The protostar emits dense gas in a fast series of events, or in gusts, and its intense magnetic field constrains the jet to a single direction. It is one of the aims of current research to unveil the physical mechanism responsible for such emission.

In the case of HH 34, observations in the course of more than 20 years have enabled us to follow, in real time, the development of this jet.
