'An analysis of hibonite, thought to be among the oldest minerals in the Solar System, has shown the turbulent and violent early history of our sun. '
'There was a surprisingly strong signal for helium and neon in the oldest minerals, which suggests that the newer material did not experience the same levels of radiation. '
'The temperature would have been more than 1,500 degrees Celsius (2,732 Fahrenheit) and as the disk cooled, the blue hibonite crystals formed. '
'"In addition to finally finding clear evidence in meteorites that disk materials were directly irradiated, our new results indicate that the Solar System's oldest materials experienced a phase of irradiation that younger materials avoided. '
'"Almost nothing in the Solar System is old enough to really confirm the early Sun's activity, but these minerals from meteorites in the Field Museum's collections are old enough. '
