Summary:
 How long did it take our Sun to form in its stellar nursery?
 Scientists are now closer to an answer.
 They succeeded in the measurement of the bound-state beta decay of
 fully-ionized thallium ions at the Experimental Storage Ring (ESR) of GSI/FAIR.
 This measurement has profound effects on the production of radioactive lead in
 asymptotic giant branch (AGB) stars and can be used to help determine the Sun's
 formation time.
