  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.

    By studying movements (like sound waves) on the surface of the star suggest Betelgeuse is still fusing helium. That would mean that the star is not close (on a human timescale) to erupting as a ...

    Humanity has marveled at the vivid star Betelgeuse for many millennia. Over two thousand years ago, this imperious red object in the constellation Orion caught the eye of the Roman poet Horace:But ...

  6. Red giant - Wikipedia

    en.wikipedia.org/wiki/Red_giant

    Very-low-mass stars are fully convective [16] [17] and may continue to fuse hydrogen into helium for up to a trillion years [18] until only a small fraction of the entire star is hydrogen. Luminosity and temperature steadily increase during this time, just as for more-massive main-sequence stars, but the length of time involved means that the ...

    The Hubble Space Telescope revealed why nearby red giant star Betelgeuse became surprisingly dim late last year, according to a new study. It was likely not a precursor to a supernova explosion.

  8. Antares - Wikipedia

    en.wikipedia.org/wiki/Antares

    Antares, like the similarly sized red supergiant Betelgeuse in the constellation Orion, will almost certainly explode as a supernova, [61] probably in 1.0 to 1.4 million years. [10] For a few months, the Antares supernova could be as bright as the full moon and be visible in daytime. [53]
