Massive telescope array aims for black hole, gets gusher of data

Astronomers have turned to helium-filled hard drives to capture the petabytes of data coming from the Event Horizon Telescope.

stronomers developing the Event Horizon Telescope (EHT), a synchronized network of radio antennas with a viewing field as large as the Earth, hope to soon take the first ever photo of Sagittarius A*, a massive black hole at the center of the Milky Way.

The amount of data being collected by 10 radio antennas around the globe, often located atop mountains, has forced the astronomers to turn to helium-filled hard drives for their data storage. [1]
