Here's why there wasn't a blood moon in 2012:
* Lunar eclipses happen regularly: Lunar eclipses occur a few times a year, but not every year has a total lunar eclipse visible from every location.
* No Total Lunar Eclipse in 2012: While there were lunar eclipses in 2012, there was no total lunar eclipse that could be considered a "blood moon."
To find out when the next total lunar eclipse (and potential "blood moon") will occur, you can check reputable sources like NASA or astronomy websites.
