Beginning late summer of 2019, the reddish star Betelgeuse has dropped from the 7th to the 21st brightest star in the nighttime sky. No need to panic, but If it exploded, the flash would be visible in the daytime, and rival the brightness of the Moon for weeks. https://t.co/KHvJjV3neB — PolitiTweet.org
