More star fuel found in space
Dr Braun has discovered that galaxies around us are hiding about a third more atomic hydrogen gas than previously calculated. Image: chemc/iStockphoto More atomic hydrogen gas — the ultimate fuel for stars — is lurking in today's Universe than we thought, CSIRO astronomer Dr Robert Braun has found.This is the first accurate measurement of this gas in galaxies close to our own.Just after the Big Bang the Universe's matter was almost entirely hydrogen atoms. Over time this gas of atoms came together and generated galaxies, stars and planets — and the process is still going on. Astronomers want to understand where, when and how the atomic gas is transformed to better understand the Universe in which we live.By taking a new look at some archival data, Dr Braun, Chief Scientist at CSIRO Astronomy and Space Science in Sydney, Australia, has discovered that galaxies around us are hiding about a third more atomic...
