Betelgeuse has entered an uncommon period of brightening again, this time rising in brightness by around 50 percent. Is the star about to go supernova?
This is what Betelgeuse may have looked like up until about 1 million years ago, when it was a main-sequence star. The surface of Betelgeuse shows enhancement of nitrogen, relatively low levels of carbon, and a high proportion of 13 C relative to 12 C , all indicative of a star that has experienced the first dredge-up .
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 ...
Betelgeuse; Epsilon Pegasi; Zeta Cephei; Lambda Velorum; Eta Persei; 31 and 32 Cygni; Psi 1 Aurigae; 119 Tauri; Mira was historically thought to be a red supergiant star, but is now widely accepted to be an asymptotic giant branch star. [32] Some red supergiants are larger and more luminous, with radii exceeding over a thousand times that of ...
The facility was laid out in 1911, with construction beginning in 1912, [6] as the State Rifle Range for the use of the state militia. Between 1922 and 1942, it was named after the then serving Governor of Virginia, being firstly named Camp Trinkle (1922–1926), then Camp Byrd (1926–1930), Camp Pollard (1930–1934), Camp Peery (1934–1938), and Camp Price (1938–1942).
