James Webb telescope: Baby star launches giant jets and shocks

“As we said, the main wavelength for looking at these things – for looking at shocked molecular hydrogen – is 2.12 microns, or roughly four times longer than the mid-visible. But for the first time, we now have a good colour image of this particular object because we’re able to observe it at other wavelengths that you just couldn’t see from ground telescopes. And that will help us get into what’s really happening in the jets,” said Prof McCaughrean.
