Fullerenes help explain why there’s so much molecular hydrogen in space | Research
Fullerenes can catalyse the formation of hydrogen molecules in interstellar clouds. The finding could help to explain why space is brimming with molecular hydrogen despite cold environments that should make its formation improbable.
‘The…
