He James Webb Space Telescope of the POT is leaving astronomers in awe with its astonishing ability to reveal precise details of the outflow of an star youngin particular, Herbig–haro 211these stars are still found in the heart of the molecular clouds that saw them be bornsurrounded by gas and dust that obscured their vision.
One of the most notable features of Telescope Space James Webb It is its ability to observe in the closest environment, which makes it an invaluable tool for studying newborn stars and their flows, since the infrared emission crosses this obstacle, and this is where the Webb It demonstrates its worth thanks to the instruments it has.
The image obtained from Herbig-Haro 211 reveals an exit from a Class 0 protostar, that is, a star in its first stages of formation, a true infant analogue of our Sun, the National Aeronautics and Space Administration (POT).
But what is really surprising is the resolution of this imagewhich is approximately 5 to 10 times larger than any previous image of HH 211.
What does the image captured by the Webb mean?
The image shows a series of shock arcs extending to the southeast and northwest, as well as a narrow bipolar jet driving them. What makes this scene even more intriguing is the mirror symmetry with which the inner jet “wiggles” to either side of the protostar central.
According to information revealed by the POTthis finding suggests the possibility that the protostar be, in fact, an unresolved binary star, an intriguing phenomenon in the training stellar.
Space mysteries finally revealed
He James Webb Space Telescope also allowed the research community to determine that the efflux of Herbig–Haro 211 It is relatively slow compared to protostars more evolved with similar flows.
Measurements indicate speeds of approximately 48 to 60 miles per second for the innermost exit structures, but the speed difference between these sections and the parent material they collide with is noticeably smaller. This crucial piece of information has led to the conclusion that emissions of stars youthslike the one in the center of HH 211are composed mainly of molecules, since the speeds of the shock waves are not energetic enough to split the molecules into simpler atoms and ions.
