Webb space telescope spies precocious 'teenage' galaxies
  + stars: | 2023-11-21 | by ( Will Dunham | ) www.reuters.com   time to read: +5 min
But Webb has obtained even better data on galaxies a bit further along in development. The gas detected in star-forming regions - stellar nurseries - of teenage galaxies was much hotter, at about 24,000 degrees Fahrenheit (13,350 degrees Celsius), than observed in galaxies today. The galaxies were observed glowing with eight elements - hydrogen, helium, oxygen, nitrogen, sulfur, argon, nickel and silicon. Incidentally, oxygen is also the third-most abundant element in the universe (behind hydrogen and helium)," Strom said. The new study presents the first results from the CECILIA Survey that uses Webb to scrutinize the chemistry of distant galaxies.
