  2. Betelgeuse - Wikipedia

    en.wikipedia.org/wiki/Betelgeuse

    The time until Betelgeuse explodes depends on the predicted initial conditions and on the estimate of the time already spent as a red supergiant. The total lifetime from the start of the red supergiant phase to core collapse varies from about 300,000 years for a rotating 25 M ☉ star, 550,000 years for a rotating 20 M ☉ star, and up to a ...

    Plans were further frustrated at Leixões, where a ship had run aground across the harbour entrance, preventing Betelgeuse from berthing there to discharge her cargo. Betelgeuse was then instructed to sail for Whiddy Island. [2] She first put in at Vigo, Spain, to change some of her crew, and then sailed for Whiddy Island on 30 December 1978.

    The Orion region showing the red supergiant Betelgeuse. Red supergiants are rare stars, but they are visible at great distance and are often variable so there are a number of well-known naked-eye examples: Antares A; Betelgeuse; Epsilon Pegasi; Zeta Cephei; Lambda Velorum; Eta Persei; 31 and 32 Cygni; Psi 1 Aurigae; 119 Tauri

    en.wikipedia.org/wiki/Variable_star

    Comparison of VLT-SPHERE images of Betelgeuse taken in January 2019 and December 2019, showing the changes in brightness and shape. Betelgeuse is an intrinsically variable star. A variable star is a star whose brightness as seen from Earth (its apparent magnitude) changes systematically with time.
