To give a little more background information, the picture above is a colourised monochrome image of HH288 taken in the 2.12 micron wavelength line of shocked molecular hydrogen.

This is a classic tracer of outflows & jets from very young, embedded protostars, including HH211 & HH212, other jets we discovered in the 90s.

But The Dragon Jet appears to be associated with a significantly more massive protostar, or more's the point, protostars – there are several outflows here in fact.
