ANU astrophysicist and cosmologist Dr Brad Tucker says the James Webb Space Telescope's mirror - which is bigger than that of the Hubble telescope - will allow for objects in space to be seen in greater detail. On Saturday the James Webb Space Telescope - some three decades and billions of dollars in the making - left earth bound for a historic mission. "The James Webb telescope is designed to look further and at fainter objects than what we can currently see with the Hubble Space Telescope," Dr Tucker told Sky News Australia. He said the limit with telescopes is essentially how big the mirror is. "They're giant light buckets, and so the bigger the bucket, the fainter or further light you can see. "And since the James Webb is much bigger than Hubble, it will be able to see fainter objects in space."
