3 Μαΐ 2023 · By observing it in ultraviolet light, Hubble can get a close look at the hot layers of atmosphere above the star's surface. While Hubble remains a primary tool for scientists exploring Betelgeuse, the star’s future and the evolving ways in which humanity explores this strange star remain open-ended.
7 Ιουν 2023 · Despite its relatively young age, Betelgeuse has already run out of the hydrogen fuel in its core and is now in the final, red giant stage of its life, fusing helium to carbon. You may like
9 Ιουν 2023 · Betelgeuse is the closest red supergiant (RSG), therefore it is well suited to study the complex processes in its atmosphere that lead to the chemical enrichment of the interstellar medium....
1 Ιουν 2023 · The atmosphere of Betelgeuse is observed to harbour magnetic fields of ∼1 G as measured by circular polarisation (Mathias et al. 2018) and as inferred from the Zeeman effect (Aurière et al. 2010).
Betelgeuse is the tenth brightest star in the night sky and the second brightest star found in the constellation Orion, located at the eastern shoulder of the hunter. At near-infrared wavelengths, however, the rust-colored star is the brightest star in the sky.
15 Μαΐ 2023 · Based on the star’s brightness, color, size and estimated age, scientists believe Betelgeuse is still early in the process of fusing helium into carbon—which it must then fuse into...
