Sentences with phrase «faint objects with»

Redshift is a measure of how much the Universe has expanded since the light left a distant source and can only be determined for faint objects with a spectrograph on a powerful large telescope such as the Keck Observatory's twin 10 - meter telescopes, the largest on Earth.
