Here's Why the 15 Days of Darkness Rumor Is a Hoax
The rumor seems to have originated on the fake news site NewsWatch33, who claim:
First red flag: there has been no such confirmation from NASA. There was, in fact, a recent Venus Jupiter conjunction, and NASA has reported on that astronomical event, but there is no mention of a blackout anywhere on their website.
But still, the rumor has taken social media by storm, with many actually taking it seriously:

A real text I just received from megan: Is it true the earth is going to experience 15 days of complete darkness starting next weekend?— Linzdawg (@lilraham) November 4, 2015
NASA SAYS 15 DAYS OF DARKNESS IN NOV WTF.ALSO NOV 13 UNIDENTIFIED OBJECT TO HIT EARTH. THEY HAVE NO IDEA WHAT IT IS OR JUST NOT TELLING !— wakeeeewake (@ryen_ryemc915) November 2, 2015
I'm uber pumped for that 15 days of darkness— SAM (@itssamiwesley) November 2, 2015
Putting aside the fact that NASA hasn't confirmed these reports, the rumor itself is fairly ridiculous. The report claims that the Venus-Jupiter conjunction will "heat up Jupiter" causing some kind of "reaction" that releases hydrogen, which will then heat the sun's surface. This is already implausible, as the conjunction only makes Venus and Jupiter appear very close from an earthly perspective. They are still 775 million km away from each other, which is far too distant for Venus to raise Jupiter's temperature.
But then it gets really crazy:
Putting aside for a second that a sentient Sun that can "attempt" anything would be much more terrifying than a 15-day blackout (not to mention another good premise for a sci-fi movie), this makes no sense. First, the Sun isn't a red giant, it's a yellow dwarf, so there's that. Plus, the Sun would only become blue if it doubled its surface temperature. Not only would this make the Sun brighter, not dimmer, but it would make Earth uninhabitable. As far as we know, NASA doesn't anticipate that happening anytime soon.
