The Mega Millions jackpot is now the largest in U.S. lottery history.
Georgia Lottery officials say the jackpot reached $500 million on Wednesday. It has rolled 18 times since Marcia Adams of College Park won $72 million in the Jan. 24 drawing.
A winner could get $19.2 million a year for 26 years or a single payment worth $359 million. The next drawing is Friday at 11 p.m.
Previously, the largest jackpot was $390 million, won by two players in Georgia and New Jersey in March 2007.
