Another Incredibly Rare Fossil Cloud Found
via MOTHERBOARD
Researchers believe the hydrogen within the cloud was produced minutes after the Big Bang and has somehow managed to remain almost entirely untainted by metals from exploding stars for 1.5 billion years, making this fossil incredibly rare. Understanding the distribution of these fossil clouds can help astronomers better understand how heavy metals were distributed in the early universe and why some gas clouds formed stars and galaxies while others didn’t.
