For starters, it\u2019s MASSIVE; so big that if it were at the center of our Solar System, it would engulf all the planets up to Jupiter. Its diameter is roughly 1,000 times that of our Sun! To find it, just look at the Orion constellation. If Orion is \u201cThe Hunter\u201d with his iconic three-star belt, then Betelguese is the hunter\u2019s left shoulder. If you\u2019re in the Northern Hemisphere during the first few days of January, you can see Betelguese rising in the east just after sunset. All other times, this star is easy to spot no matter where you\u2019re located in the world! Especially September through March.<\/p>\n<p>Some of the earliest known records of Betelguese come from China in the 1st century BCE. These records describe Betelgeuse as being yellow\u2026 which is strange, because just a few years later, in 150 CE, the Egyptian astronomer Ptolemy described Betelguese as red. This indicates that Betelgeuse rapidly underwent a stellar phase change sometime between the time these two records were made, evolving to become the red giant that it is today.<\/p>\n<p>Betelgeuse&#8217;s propensity for fading and brightening over a multi-year cycle also seems to have caught people\u2019s attention. In western Aboriginal Australian oral tradition, Betelguese represents the \u2018fire magic\u2019 used by a love-struck hunter to reach the object of his affection. Unfortunately, the fire magic\u2019s tendency to flicker out ultimately causes him to fail. While Sir John Herschel continues to be recognized as the first to notice Betelguese\u2019s variable brightness, it\u2019s clear that people living before the 19th century also recognized what was going on.<\/p>\n<p><span class=\"style-scope yt-formatted-string\" dir=\"auto\">Read more: <\/span><\/p>\n<p><span class=\"style-scope yt-formatted-string\" dir=\"auto\">Betelgeuse went dark but didn\u2019t go supernova.
