Star War Greatest Dad In The Galaxy Shirt
My 5th-grade teacher (10 years old for non-Americans) told us about Betelgeuse and how it could turn supernova any day. At the time I didn’t understand “any day” in a cosmic sense is a lot different than “any day” to a 10-year-old .but from that day on I was fascinated by the cosmos and I had always wanted to see a supernova. That was just about 20 years ago now, so thank you, OP, for delivering on a childhood dream of Star War Greatest Dad In The Galaxy Shirt mine In astronomy, there is a Doppler effect with a light called “red-shift”. This means that the distance between our two closest stars would be only 0.004% of the journey between the two edges of our galaxy.
Man, imagine how terrifying it would be to yank the Earth out of orbit, flinging it somewhere else. We’d be in total darkness, spinning around, gravity all messed up. Starting in October 2019, Betelgeuse began to dim noticeably, and by mid-February 2020 its brightness had dropped by a factor of approximately 3, from magnitude 0.5 to 1.7. By 22 February 2020, Betelgeuse stopped dimming and started to brighten again. Infrared observations found no significant change in brightness over the last 50 years, suggesting that the dimming is due to a change in extinction rather than an underlying change in the Star War Greatest Dad In The Galaxy Shirt luminosity of the star. Further studies suggested that occluding “large-grain circumstellar dust” may be the most likely explanation for the dimming of the star. What you’re thinking of as fade is probably attenuation.
