The coolest would be that some stars can have temperature of "barely lukewarm". I know they're brown dwarfs but that counts as stars. And WISE 0855-0714 is not even lukewarm, it's below water freezing point! Makes you really think about... well, what temperature is (anything above 0K). If that's not cool, idk what.
As for the scariest... well, when I was a kid I was afraid about the Sun dying. My tiny brain couldn't comprehend that I won't live for 5 billion years anyway. Used to have nightmares about the Sun frying the Earth. Now it's gamma ray bursts, I suppose. My brain is only slightly bigger now and it cannot understand probabilities and chances well.
