Turns out, cosmic dust in the early universe wasn’t made the way we thought! NASA’s James Webb Space Telescope found a star in a primitive galaxy making dust almost entirely out of iron—not the usual heavy elements like silicon or carbon. This totally flips what scientists believed about how the universe’s first galaxies formed. Imagine: the universe was building with totally different ingredients than we see today. Space is full of surprises! #Science #NASA #JamesWebb
