[ad_1] The telescope itself consists of an 8.4-foot wide dish antenna along with mirrors, lenses and detectors designed to capture far-infrared light. Because far-infrared telescopes need to be kept cold, it will also carry a cryocooler that keeps the detectors close to -451.3 degrees Fahrenheit, just a shade above absolute zero. NASA, ESA, N.

Using the Gaia space telescope, these researchers were able to take more precise measurements of the position, brightness and distance of roughly one million stars. They also looked at […]
