A lot of the water on Earth is believed to have originally formed in space, but scientists aren't sure how.
"We don't understand yet how some of the most important molecules here on Earth are made in space," said Berengere Parise, an astrochemist at the Max-Planck institute for Radio Astronomy in Germany who co-authored the paper. "But our discovery of hydrogen peroxide with APEX seems to be showing us that cosmic dust is the missing ingredient in the process."
