When the team of geologists from Stanford University re-created these conditions in a lab to try to duplicate an ultralow - velocity zone, they found that iron — one of the more abundant minerals on Earth and a likely candidate material that might explain the zones — reacted with the seawater to create a form of iron peroxide that was saturated with hydrogen atoms, according to the new research.

«Such galaxies, which have remained dormant for most of their lives, are believed to contain the chemical elements forged a few minutes after the Big Bang.By measuring the relative number of hydrogen and helium atoms in the Little Cub we might be able to learn more about what made up the Universe in the moments after it began 13.7 billion years ago,» Cooke added.
