superconducting nanowire

Okay, so not room-temperature.

To reduce noise levels, the detector was cooled to just below 1 Kelvin

Jesus.

1 ms per-pixel acquisition time

Yeah, that tracks.

The fact this works in daylight is still mindboggling. Could this be used for astronomy? If they can bump up the distance by a few orders of magnitude, maybe relax their superconductors to merely LN2 levels, we could image the shit out of Venus.
