Africa-Press – Mauritius. <\/strong><\/span>Imagine you could go back in time 4.6 billion years and take a picture of our Sun just as it was being born. What would it look like? Well, you can get a clue from this glorious new image acquired by the James Webb Space Telescope (JWST).<\/p>\n

Towards the centre of this object, called HH212, is a star coming into existence that is probably no more than 50,000 years old. The scene would have looked much the same when our Sun was a similar age.<\/p>\n

You can\u2019t see the glow from the protostar itself because it\u2019s hidden within a dense, spinning disc of gas and dust. All you get are the pinky-red jets that it\u2019s shooting out in polar opposite directions.<\/p>\n

HH212 is sited in Orion, close to the three brilliant stars that make up the \u201cbelt\u201d of the mythical hunter that gives the constellation its name. The distance from Earth is about 1,300 light-years.<\/p>\n

Physics suggests those dramatic outflows of gas are the means by which the nascent star regulates its birthing. \u201cAs the blobby ball of gas at the centre compacts down, it rotates.<\/p>\n

But if it rotates too fast, it will fly apart, so something has to get rid of the angular momentum,\u201d explained Prof Mark McCaughrean. \u201cWe think it\u2019s jets and outflows.<\/p>\n

We think that as all the material shrinks down, magnetic fields are pulled together and then some of the material coming in through the disc gets captured on magnetic fields and is thrown out through the poles.<\/p>\n

That\u2019s why we call these structures bi-polar,\u201d the European Space Agency senior scientific advisor told BBC News. The pinky-red colour denotes the presence of molecular hydrogen. That\u2019s two hydrogen atoms bonded together (rather like the \u201cHH\u201d in the protostar\u2019s name).<\/p>\n

Shockwaves are moving through the outflows, energising them and making them glow brightly in this Webb picture, which was captured predominantly at the infrared wavelength of 2.12 microns (that\u2019s the second part of the protostar\u2019s name!).<\/p>\n

In the annotated picture above, look closely at the left and right jets, and trace the knots of brightness in each of them. Count the bowshocks \u2013 where faster material has crashed into slower material just ahead of it.<\/p>\n

The structures are remarkably symmetric. . . except there appears to be an additional, albeit very messy bowshock on the right. In fact, there\u2019s probably a complementary bowshock on the other side.<\/p>\n

There are certainly pinky hints of it in a wider version of this Webb image. It\u2019s just that the density of gas and dust in space in that direction is thinner and so there\u2019s less material to excite and so the shock structure appears much more diffuse.<\/p>\n

Astronomers have been studying HH212 for 30 years, taking pictures every now and then to see how it\u2019s changed. As you might expect from the Webb supertelescope, its new view is 10 times sharper than anything we\u2019ve had before and will enable scientists to delve deeper into the processes that drive star formation.<\/p>\n

A nice feature is to run together the entire image history to make a movie, to see how elements in the jet structures change over time. Repeat observations mean you can also gauge the speed at which those elements are moving \u2013 at 100km per second and more.<\/p>\n

I\u2019ve kind of suggested the HH stands for molecular hydrogen, and it\u2019s a neat fit. But it really stands for Herbig-Haro, after George Herbig and Guillermo Haro, who did the pioneering work on this type of object in the 1940s and 50s.<\/p>\n

They would no doubt be amazed by the capabilities of JWST. It\u2019s not just the sharpness of image that Webb can achieve with its 6.5m primary mirror, it\u2019s also the breadth of colour its instruments can now detect that makes the telescope so special.<\/p>\n

\u201cAs we said, the main wavelength for looking at these things \u2013 for looking at shocked molecular hydrogen \u2013 is 2.12 microns, or roughly four times longer than the mid-visible.<\/p>\n

But for the first time, we now have a good colour image of this particular object because we\u2019re able to observe it at other wavelengths that you just couldn\u2019t see from ground telescopes.<\/p>\n

And that will help us get into what\u2019s really happening in the jets,\u201d said Prof McCaughrean. Webb was intended to be transformative in many fields of astronomy, and the study of Herbig-Haro objects has definitely benefitted.<\/p>\n

Look below and you can marvel at HH212\u2019s cousin, called HH211. This object, located in the Perseus constellation, is even younger, again measured in mere thousands of years. To think our Sun started out like this.<\/p>\n
