"Comet" Lovejoy survived almost an hour in ove a million degrees of heat in the Sun's corona, 87K from the surface. Comets are balls of ice and snow.
Here's your Home Science Experiment: Place an ice cube in a pan under a 500 degree broiler for a half hour. Observe what happens.
Now, based on your observation, try to explain how "Comet" Lovejoy could possibly be made of ice.
Oh yeah, and for extra credit, explain why the Sun's X-Ray flux flatlined for two days during Lovejoy's approach.
That's one tough ice cube!
Would like to offer a theory and some fact. Matter being neither able to be created nor destroyed, (theory) the comet vaporized, the vapor continued on trajectory, and simply reassembled after leaving the Sun? Unknown, and speculation.
