FUSE Helps to Solve the Deuterium Puzzle: New Theories Needed

“Hidden” Milky Way Deuterium Found. ‘Scientists using NASA’s Johns Hopkins University-operated Far Ultraviolet Spectroscopic Explorer (FUSE) satellite have learned that far more “heavy” hydrogen remains in our Milky Way galaxy than expected, a finding that could radically alter theories about star and galaxy formation. This form of hydrogen, called deuterium, was created a few minutes after the Big Bang, but has been slowly destroyed as it is burned in stars and converted to heavier elements. In fact, it now turns out, that destruction has been occurring even more slowly than previously thought. Published in the Aug. 20 issue of the Astrophysical Journal, the FUSE team’s new large deuterium survey solves a 35-year-old mystery concerning deuterium’s uneven distribution in the Milky Way galaxy even as it poses new questions about how stars and galaxies are made.’

The Deuterium Puzzle Solved?

Far Ultraviolet Spectroscopic Explorer (FUSE). ‘FUSE is a NASA-supported astrophysics mission that was launched on June 24, 1999, to explore the Universe using the technique of high-resolution spectroscopy in the far-ultraviolet spectral region.’
