Since I had to look it up out of curiosity/paranoia, I figure someone else might also be interested/relieved to know:
Betelgeuse has frequently been the subject of scare stories and rumors suggesting that it will explode
within a year, leading to exaggerated claims about the consequences of such an event. The timing
and prevalence of these rumors have been linked to broader misconceptions of astronomy, particularly
to doomsday predictions relating to the Mayan calendar. Betelgeuse is not likely to produce a gamma-ray
burst and is not close enough for its x-rays, ultraviolet radiation, or ejected material to cause
significant effects on Earth.
