A BIG NEW SUN-GRAZING COMET
?Astronomers are monitoring a new sun-grazing comet discovered just a few days ago by the ATLAS survey.
?It appears to be unusually big, and could become a significant naked-eye object by the end of October.
?Experts say if it survives its close encounter with the sun -- a big IF - -it could rival Comet Lovejoy in 2011??
