The diminution in Betelgeuse's apparent size equates to a range of values between 56.0 ± 0.1 mas seen in 1993 to 47.0 ± 0.1 mas seen in 2008— a contraction of almost 0.9 AU in 15 years. [57] The observed contraction is generally believed to be a variation in just a portion of the extended atmosphere around Betelgeuse, and observations at ...
Betelgeuse is one of the best-known stars in the night sky, as well as the easiest to find. New examinations of this behemoth star suggest it is both smaller — and closer — than astronomers ...
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
This tribunal took a year to hear evidence and prepare a 480-page report. [11] The report indicated three main factors had contributed to the incident: The poor condition of Betelgeuse for which its operator, Total S.A., was to blame: Immediately before the incident, the vessel's hull and tanks were cracked, corroded, and leaking. The eleven ...
In late 2019 and early 2020, Betelgeuse blew its top. Literally. Around that time the famous bright star marking the right shoulder of Orion suddenly started dimming, dropping to about half its ...
To expand on the work of the 20-foot interferometer, Pease, Michelson and George E. Hale designed a 50-foot interferometer which was installed at Mount Wilson Observatory in 1929. It successfully measured the diameter of Betelgeuse, but, other than beta Andromedae, could not measure any stars not already measured by the 20-foot interferometer. [20]
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. This variation may be caused by a change in emitted light or by something partly blocking the light, so variable stars are classified as either: [1]
They are quickly discovered by the Vogons, who torture them by forcing them to listen to their poetry and then toss them out of an airlock. Meanwhile, Zaphod Beeblebrox , Ford's "semi-cousin" and the President of the Galaxy, steals the spaceship Heart of Gold at its unveiling with his human companion, Trillian .
