I hadn't read about the CHIME (Canadian Hydrogen Intensity Mapping Experiment) telescope before.

From the wikipedia article:

> The telescope's low-noise amplifiers are built with components adapted from the cellphone industry and its data are processed using a custom-built FPGA electronic system and 1000-processor high-performance GPGPU cluster.

that's super interesting. My limited exposure to radio astronomy relies on a lot more custom collection hardware (super cooled LNAs, with hydrogen maser clocks, ...) and mostly pure software processing. Seeing this very COTS hardware with careful processing systems is neat.

> The telescope consumes 250 kilowatts of power.

woah.
