Observing Betelgeuse, which is estimated to be about 10 million years old, allows astronomers to watch what happens late in the lifetime of a star. As Betelgeuse burns through fuel in its core, it ...
One of the biggest and brightest stars in the night sky has left astronomers puzzled after it has faded dramatically over the last year. Some have speculated that this is a sign of an impending ...
The star is Betelgeuse, a red supergiant in the constellation Orion. The asteroid is Leona, a slowly rotating, oblong space rock in the main asteroid belt between Mars and Jupiter.
If Betelgeuse explodes, it will become as bright as the full moon in a matter of days and be visible during day time. Betelgeuse: star's weird dimming sparks rumours that its death is imminent ...
The most likely star-formation scenario for Betelgeuse is that it is a runaway star from the Orion OB1 association. Originally a member of a high-mass multiple system within Ori OB1a, Betelgeuse was probably formed about 10–12 million years ago, [159] but has evolved rapidly due to its high mass. [107] H.
The Lambda Orionis Cluster (also known as the Collinder 69) is an open star cluster located north-west of the star Betelgeuse in the constellation of Orion. It is about five million years old and roughly 1,300 ly (400 pc) away from the Sun. [1] Included within the cluster is a double star named Meissa.
Astronomers pointed powerful telescopes at the red giant star Betelgeuse, confirming theories that the star had not almost exploded a few years ago, but it did experience a dimming event.
Xi Orionis (ξ Orionis) is a binary star system in the northeastern part of the constellation of Orion, well above the red giant star Betelgeuse in the sky. It lies next to another blue main-sequence star, Nu Orionis, which is somewhat closer at 520 light-years' distance.
