I don’t know much about physics/astronomy. My rough understanding is that very early in the Big Bang, all matter/energy was condensed into some really exotic form and it turned into atoms and molecules as it expanded. When I read the headline, I imagined that during the Big Bang a molecule was produced that somehow had a lot of energy and emitted that energy in such a way that we managed to detect some kind of echo of it today. I have seen images described as images of radiation from the Big Bang, so this sounded impressive but not unbelievable to me.
