Trihydrogen tagged posts

From helping catalyze interstellar reactions and fueling the birth of stars to its presence in neighborhood gas giants like Saturn and Jupiter, trihydrogen, or H3+, is best known as the “the molecule that made the universe.”

While we have a clear picture of how the majority of H3+ is formed—a hydrogen molecule, or H2, colliding with its ionized counterpart, H2+—scientists are keen to understand alternative sources of H3+ and to better measure its abundance throughout the cosmos...

Trihydrogen, H3+, is called the molecule that made the universe, where it plays a greater role in astrochemistry than any other molecule. While H3+ is astronomically abundant, no scientist understood the mechanisms that form it from organic molecules. Until now. Using lasers, Michigan State University scientists have unlocked the secret and published their results in the current issue of Scientific Reports...
