HI,

I think it's amazing they have been able to locate a change in light emitted from the star and that they've been able to conclude that is was a 100km wide comet that was responsible for the noted change.

Since my knowledge in astronomy is good but not to the extremes, I'm know they've been able to know the difference in magnitude but how did they conclude it was a comet? Did the volatiles in the comet give the star some distortion in it's power outage, disrupted somehow by the relatively "small" 100km wide object.. When I think about it, the star is huge in comparison..

Great discoveries incite our imagination, thanks for bringing in that topic!
