Cooling the "largest astronomical instruments ever" | European Southern Observatory
The light gathered by European Southern Observatory's Extremely Large Telescope (ELT) will be captured by house-sized instruments that need to be cooled down to detect faint signals from the cosmos. How do we cool these huge systems to as low as -270 ºC? Our engineers are hard at work at it.
