At present, earth-based radio telescopes cannot detect the faint light emitted from the earliest stars, especially since the earth's atmosphere absorbs far-infrared light. Complicating matters further, as our universe expands, the light grows ever harder to detect. These stars are moving away from us nearly at the speed of light, and their light appears as the longest of the infrared wavelengths. Scientists aim to have satellite-based telescopes up within 20 years. In the meantime, as the stars continue to race away and scientists race to build and test better photo detectors they'll have their work cut out for them.
