Hydrogen peroxide has been detected for the first time in interstellar space, offering hints about the origin of water, a similar molecule.

The chemical signature of hydrogen peroxide molecules, which consist of two oxygen atoms bookended by two hydrogen atoms, was detected in dense clouds of cosmic gas and dust in a distant part of our own galaxy, the Milky Way, reported the study published Wednesday in Astronomy & Astrophysics.

The light signals were captured by the European Southern Observatory's Atacama Pathfinder Experiment telescope (APEX) in the Chilean Andes.

But the chemical best known on Earth as an antiseptic, rocket fuel and bleach isn't likely to give interstellar tourists blond highlights in their hair, even if they somehow manage to make the 400 light-year journey from Earth.

"The amount of hydrogen peroxide in the cloud is just one molecule for every 10 billion hydrogen molecules, so the detection required very careful observations," said Per Bergman, lead author of the study, in a statement. Bergman is an astronomer at Onsala Space Observatory in Sweden.

The discovery is exciting for astronomers because water can be produced when hydrogen peroxide reacts with hydrogen under the right conditions. A lot of the water on Earth is believed to have originally formed in space, but scientists aren't sure how.
