Mysterious hot spots observed in Betelgeuse

On a side note, one of my goals in life is to have a life long enough to
see Betelgeuse explode as a supernova. It must be spectacular to be able
to see an astronomical object besides the Sun during the daylight hours!
Betelgeuse may be the only star close enough to become bright enough to
see in the daylight. I don't know if anything like this was ever seen on
Earth before, but if it was, then it must've been the dinosaurs or the
amoebas who saw it back then. If it was the dinos, then they must've
been simply puzzled by the good nocturnal hunting conditions that were
suddenly available. If it was the amoebas & algaes, then they must've
just been surprised by how easy it was to photosynthesize at night.

The hot spots appear on opposite sides of Betelgeuse, separated by about half the star’s visual diameter. They have a temperature of about 6700°–8500° Fahrenheit (3700°–4700° Celsius), much higher than the average temperature of the star’s radio surface (some 1700° F [930° C]) and even higher than the 6000° F (3300° C) visual surface. The arc of cool gas lies almost 4.5 million miles (7.4 billion kilometers) away from the star — about the same as Pluto’s farthest distance from the Sun. Scientists estimate the gas has a mass almost two-thirds that of the Earth and a temperature of only –190° F (–123° C).
