The NASA Spitzer and Hubble space telescope have been busy discovering the signs of planet formation Spitzer has discovered for the first time dusty discs around mature Sun-like stars known to have planets. Meanwhile Hubble produced some of the most detailed images ever of a brighter disc circling a much younger Sun-like star. Dr. Charles Beichman , the lead astronomer, explained to NASA that "Young stars have huge reservoirs of planet-building materials, while older ones have only leftover piles of rubble. Hubble saw the reservoirs and Spitzer, the rubble," Dr. Beichman explained further that "The new Hubble image gives us the best look so far at reflected light from a disc around a star the mass of the Sun," |
