“Did you have a heavy metal phase when you were a teenager? Well, so did galaxies! That’s right, astronomers have discovered that “teenage” galaxies are into heavy metal: nickel. This surprising find is just one of several discoveries among galaxies that formed in the first 3 billion years after the Big Bang. The team combined the light spectra of 23 out of 33 teenage galaxies observed last summer to create a composite picture of a standard young galaxy. This allowed them to highlight some shared compositional insights. The presence of eight elements literally shone through. Hydrogen, helium, nitrogen, oxygen, silicon, sulfur, argon, and nickel were detected. But it wasn’t just the presence of nickel that was unusual. The galaxies tend to be at higher temperatures. Teenage galaxies’ hot pockets are at over 13,350 degrees Celsius (24,062 degrees Fahrenheit), significantly higher than for galaxies in the current universe which are about 9,700 degrees Celsius (17,492 degrees Fahrenheit). These galaxies were different. And we want to understand those differences and how they change over time. Together this will provide a more accurate picture of galaxy evolution through the ages of the universe. So next time you’re feeling nostalgic for your teenage years, just remember that you were just like a “teenage” galaxy: full of heavy metal and hot pockets!”
