Months after its July fly-by, New Horizons is still squeezing its images down pipe measured in bits-per-second – and that's a problem space boffins would like to solve in the future.

As we know from NASA's successful LADEE test, lasers are a viable and truly broadband space comms medium – but firing a laser from (say) Mars and receiving it on Earth would need a Bloody Big Telescope.

That's what boffins from Japan and Madrid reckon the world will have, once the proposed Cherenkov Telescope Array (CTA) is built, so in this ArXiv paper, they propose using that instrument for deep-space optical communications.

The CTA is going to have dozens of instruments of varying size (from 6m up to 24m) in both hemispheres, a requirement for deep space communications, and as Alberto Carrasco-Casado (National Institute of Information and Communications Technology in Tokyo) and collaborators José Manuel Sánchez-Pena and Ricardo Vergaz (University of Madrid) note, the instruments should be good enough to do double-service as communications receivers.

That's because handfuls of photons are exactly what the CTA receivers are designed to detect – the tiny flashes of light that cosmic rays and gamma rays produce when they collide with the upper atmosphere.

Note: "Boffin" == "Egghead" == Scientist.

    Next, I suppose, our submitters will give a dissertation on the meaning of "bollocks".

      Coming from cattle country myself I always did wonder why Britons run around yelling "Steer!"

      On the same subject, "bloody" is what you become after you faceplant while riding BMX. "Sod" is a rectangle of turf you lay down to make a lawn, ergo "sod off" means "take the lawn up again?" "Bugger" is what you say when you refrain from calling someone a "booger." "You git" means, "Get out of here."

      With regular curse words Britons fail badly. They do shine with re-purposing words of praise, as in the captain who observed our performance on the rugby pitch and pronounced it, "lovely."

    Seems to me we should be seeking to develop wide band massively parallel entanglement. Lots faster than lasers.
