Death throes of giant star puzzle researchers 2016-01-07T05:00:00Z This phenomenon may even befall Betelgeuse — the bright, red supergiant in the Orion Orion constellation — that is expected to end its life as a supernova. Betelgeuse May First Erupt As 'Supernova Impostor' 2014-08-28T04:00:00Z Both phenomena are common around red supergiant stars, and they fit with models that suggest Betelgeuse is tens of thousands of years away from exploding. Is Betelgeuse, one of the sky’s brightest stars, on the brink of a supernova? 2019-12-27T05:00:00Z Harvard astronomer Avi Loeb told Salon that, luckily, life on Earth wouldn't be affected much if Betelgeuse exploded, adding that such stars typically collapse into neutron stars or black holes. Betelgeuse is blowing up — on social media and maybe IRL 2019-12-24T05:00:00Z Shining with a distinct orange hue, Betelgeuse is a red giant star that is 700 times the size of our sun. This Week's Night Sky: Moon Hits a Bull’s Eye 2015-09-28T04:00:00Z The nutty thing Levesque and three colleagues discovered looks like an ordinary red giant star, similar in appearance to Betelgeuse, which marks one of Orion’s shoulders. A Giant Star With a Chewy Chocolate Center—Sort Of 2014-06-10T04:00:00Z Artist’s rendering from ESO showing Betelgeuse with a gigantic bubble boiling on its surface and a vast plume of gas being ejected to at least six photospheric radii or roughly the orbit of Neptune. Betelgeuse May First Erupt As 'Supernova Impostor' 2014-08-28T04:00:00Z “I honestly think that’s why Betelgeuse is such a favorite target,” she continued. Is Betelgeuse, one of the sky’s brightest stars, on the brink of a supernova? 2019-12-27T05:00:00Z Since Betelgeuse is a few hundred times closer than the supernova SN1987A, more than one million neutrinos could be detected from its explosion, compared to the tens observed from SN1987A. Betelgeuse is blowing up — on social media and maybe IRL 2019-12-24T05:00:00Z It's so large, in fact, that if it replaced the sun at the center of our solar system, the edge of Betelgeuse would reach at least to the orbit of Mars. This Week's Night Sky: Moon Hits a Bull’s Eye 2015-09-28T04:00:00Z Cooler orange stars such as Betelgeuse and Aldebaran are still a scorching 3500 degrees Celsius. Pictures: Best astronomy photos of 2012 2012-09-21T10:42:58Z Betelgeuse, roughly 15 times the mass of the Sun, is expected to also end its life as a supernova. Betelgeuse May First Erupt As 'Supernova Impostor' 2014-08-28T04:00:00Z If Betelgeuse does explode, we will be treated to a light show for the ages. Is Betelgeuse, one of the sky’s brightest stars, on the brink of a supernova? 2019-12-27T05:00:00Z It has been generally supposed that the Arabian astronomer Alfraganus, in his translation of Ptolemy’s Almagest, refers to only five red stars observed by Ptolemy, namely, Arcturus, Aldebaran, Betelgeuse, Antares, and Pollux. Astronomical Curiosities Facts and Fallacies 2012-03-27T02:00:18Z This makes it easy to estimate the angular diameter of a star, and Betelgeuse is the one which has the greatest angular diameter of all whose distances we know. Astronomy: The Science of the Heavenly Bodies 2012-03-17T02:01:02.630Z But Alpha Centauri is triple and Sirius double, and both are much hotter than Betelgeuse. Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z Aldebaran has a trace of rose-color in its light, while Betelgeuse is of a very deep orange, and Antares may be described as fire-red. Astronomy with an Opera-glass A Popular Introduction to the Study of the Starry Heavens with the Simplest of Optical Instruments 2011-07-17T02:00:30.177Z Orion, with the beautiful stars Rigel and Betelgeuse. Astronomical Myths Based on Flammarions's History of the Heavens 2011-06-24T02:00:15.873Z And, to my eye at least, Betelgeuse is redder than Arcturus. Astronomical Curiosities Facts and Fallacies 2012-03-27T02:00:18Z Antares and Betelgeuse appear to be the most inviting for investigation, because their estimated angular diameters are about one-twentieth of a second of arc. Astronomy: The Science of the Heavenly Bodies 2012-03-17T02:01:02.630Z The figures for Betelgeuse in Table 5 are interesting. Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z Rigel belongs to a new generation of the universe; Betelgeuse to the universe that is passing. Astronomy with an Opera-glass A Popular Introduction to the Study of the Starry Heavens with the Simplest of Optical Instruments 2011-07-17T02:00:30.177Z It is odd, but my recollection is that it was the "sick enchantress" who cried "unto Betelgeuse a mystic word." The Letters of Ambrose Bierce With a Memoir by George Sterling 2011-05-26T02:00:19.673Z Among the latter they only speak of Arcturus, Aldebaran, Pollux, Antares, and Betelgeuse as of a striking red colour. Astronomical Curiosities Facts and Fallacies 2012-03-27T02:00:18Z Aldebaran, Betelgeuse and Antares are well-known red stars, Capella and Alpha Ceti yellowish, Vega and Sirius blue, and Procyon and Polaris white. Astronomy: The Science of the Heavenly Bodies 2012-03-17T02:01:02.630Z Hence Alpha Centauri and even Sirius may be far more effective than Betelgeuse. Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z Betelgeuse, it may be remarked, is slightly variable. Astronomy with an Opera-glass A Popular Introduction to the Study of the Starry Heavens with the Simplest of Optical Instruments 2011-07-17T02:00:30.177Z Astrophysicists say that Betelgeuse, the red super-giant that is the ninth brightest star in the sky, is losing mass—an indication of gravitational collapse. Will the Earth Have Two Suns by 2012? 2011-01-21T22:40:00Z See the arm and the club—about seven stars in a rather poor curve—beyond the red star Betelgeuse? Earth and Sky Every Child Should Know Easy studies of the earth and the stars for any time and place But look at Betelgeuse up there, which Michelson has been able to measure. The Prairie Child These stars are older than the first, and the ruddy ones, such as Antares, Betelgeuse, α of Hercules, are still older; several of them are variable, and are on their way to final extinction. Astronomy for Amateurs First compare Aldebaran and Betelgeuse, and glance from each to the brilliant white, or bluish-white, star Rigel in Orion's foot. Astronomy with an Opera-glass A Popular Introduction to the Study of the Starry Heavens with the Simplest of Optical Instruments 2011-07-17T02:00:30.177Z He had known Betelgeuse years ago and personally had always preferred its neighbour Rigel, which had received no publicity at all. Tutors' Lane And to make sure, draw one east from Betelgeuse about the same distance. Earth and Sky Every Child Should Know Easy studies of the earth and the stars for any time and place And he estimated Betelgeuse to be two hundred and sixty million miles in diameter. The Prairie Child Although he could spot Betelgeuse and Antares because of their tremendous radiation, they were too close together for measurements; the angle subtended was too small. Islands of Space Careful observation detects a decided difference between its color and that of Betelgeuse, or Alpha Orionis, which is also a red star. Astronomy with an Opera-glass A Popular Introduction to the Study of the Starry Heavens with the Simplest of Optical Instruments 2011-07-17T02:00:30.177Z Overhead, Betelgeuse was making the most of its recent publicity, unobstructed by vagrant clouds. Tutors' Lane Here, against the misty-pale swirls of cosmic dust, they burned with color heaped on color; the bloody burning crimson of Antares, the metallic gold of Capella, the sullen pulsing of Betelgeuse. The Colors of Space This determination shows Betelgeuse to be 160 light-years from the earth. The New Heavens In the telescope Betelgeuse appears as "a rich and brilliant gem," says Lassell, "a rich topaz, in hue and brilliancy differing from any that I have seen." Half-hours with the Telescope Being a Popular Guide to the Use of the Telescope as a Means of Amusement and Instruction. Rigel and Betelgeuse and Algol rush through space, and about them probably circle numerous planets inhabited by countless and curious beings, each and all, perhaps, possessing hearts as perturbable as our own. Hints for Lovers Betelgeuse is strikingly red, while Rigel is yellow. Maria Mitchell: Life, Letters, and Journals Two of the greatest of its stars, Betelgeuse and Rigel, possess, as far as has been ascertained, no perceptible motion across the line of sight, but there is a little movement perceptible in the ``Belt.'' Curiosities of the Sky As the outer mirrors were separated the interference fringes gradually became less distinct, as theory requires, and as Doctor Merrill had previously seen when observing Betelgeuse with the interferometer used for Capella. The New Heavens We may therefore conclude that the angular diameter of Betelgeuse is very nearly the same as that of a ball one inch in diameter, seen at a distance of seventy miles. The New Heavens This actual measure of the diameter of Betelgeuse supplies a new and striking test of Russell's and Hertzsprung's theory of dwarf and giant stars. The New Heavens The angular diameter, as in the case of Betelgeuse, is in remarkably close agreement with the diameter predicted from theory. The New Heavens Fowler has already identified the bands of titanium oxide in such red stars as the giant Betelgeuse, and in others of its class. The New Heavens Turning back to Betelgeuse, they were seen beyond doubt to be absent. The New Heavens Thus, if this measure of its distance is not considerably in error, Betelgeuse would nearly fill the orbit of Mars. The New Heavens But there can be no doubt that the diameter of Betelgeuse exceeds 100,000,000 miles, and it is probably much greater. The New Heavens Three-quarters of the naked-eye stars are in the giant stage, which comprises such familiar objects as Betelgeuse, Antares, and Aldebaran, but most of them are much denser than these greatly inflated bodies. The New Heavens It now remains to make further measures of Betelgeuse, especially because its marked changes in brightness suggest possible variations in diameter. The New Heavens |
