The James Webb observatory records the giant jets and shocks created by a birthing star in Orion.
Moving at the speed of light, it would take about 1.6 years to travel the length of HH212's jetsImagine 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?Towards the centre of this object, called HH212, is a star coming into existence that is probably no more than 50,000 years old.You can't actually see the glow from the protostar itself because it's hidden within a dense, spinning disc of gas and dust.
"We think it's jets and outflows. 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. That's why we call these structures bi-polar," the European Space Agency senior scientific advisor told BBC News.
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 - where faster material has crashed into slower material just ahead of it. Astronomers have been studying HH212 for 30 years, taking pictures every now and then to see how it's changed. As you might expect from the Webb super telescope, its new view is 10 times sharper than anything we've had before and will enable scientists to delve deeper into the processes that drive star formation.
