KornmesserĮlement found in our teeth detected for the first time in galaxy 12 billion light-years away The discovery sheds a new light on how stars forge fluorine, suggesting short-lived stars known as Wolf-Rayet are its most likely birthplace. To date, this is the most distant detection of the element in a star-forming galaxy, one that we see as it was only 1.4 billion years after the Big Bang - about 10% of the current age of the Universe. ALMA observations have revealed the presence of fluorine in the gas clouds of NGP-190387. This artist's impression shows NGP-190387, a star-forming, dusty galaxy that is so far away its light has taken over 12 billion years to reach us. The observatory can both see and see through dust using its observational capabilities in infrared wavelengths of light, including the brightness of the WR 124 star, the details of the gas surrounding it and the clumpy structure of the ejected stellar material in the halo. But cosmic dust across the universe swirls together with gas to form stars, planets and the very building blocks of life.Īstronomers are trying to understand why there is more dust in the universe than their theories can explain, and tools like the Webb telescope could shed new light on this astronomical ingredient. On Earth, dust is regarded as an annoyance that needs to be cleaned up. So far, WR 124 has shed about 10 suns’ worth of material, creating the cool, glowing gas and cosmic dust seen in the image. The Wolf-Rayet star observed by Webb is 30 times the mass of our sun, which has a mass of about 333,000 Earths. The star, surrounded by a halo of glowing gas and dust, shines at the center of the image. Webb telescope spies an unusual set of nested dust rings in space Give viewers an unobscured view of the source object. They were removed from the image, in order to These are not features of the system, but so-Ĭalled artifacts of the telescope itself. Initial processing of the Webb WR 140 data included eight bright "spikes" of lightĮmanating from the center of the image. ![]()
