Hubble finds that Betelgeuse’s mysterious dimming is due to a traumatic outburst – Phys.org
Recent observations of Betelgeuse have revealed that the star’s unexpected and significant dimming periods in late 2019 and early 2020 were most likely caused by the ejection and cooling of dense hot gases, and that the star may be going through another dimmi…

Recent observations of Betelgeuse have revealed that the star’s unexpected and significant dimming periods in late 2019 and early 2020 were most likely caused by the ejection and cooling of dense hot gases, and that the star may be going through another dimming period more than a year early.
Between October and November 2019, Hubble Space Telescope observed dense, heated material moving outward through the star’s extended atmosphere at 200,000 miles per hour. The following month, several ground…
