It says, near the top of the story, "There were so many photons per second that they couldn’t keep up".
Not a single photon. Not easy (not possible?) to distinguish signal from noise with a single photon, afaik.
- anentropic 4y agoThey detected many photons, but I read this as meaning that they had focused their attention on one specific photon that was detected by their instruments: > Among those detections was a suspected high-energy photon at 18 teraelectron volts (TeV)—four times higher than anything seen from a gamma-ray burst before and more energetic than the highest energies achievable by the Large Hadron Collider.
