Is Betelgeuse burning carbon?
Betelgeuse was likely formed in the great Orion molecular cloud complex very recently on cosmic scales: within the last 10 million years. It has already finished burning through all the hydrogen fuel in its core, and has gone onto the next element, helium, which it fuses into carbon.
Is Betelgeuse burning helium?
They achieved a clearer idea than before that Betelgeuse is currently burning helium in its core. They also showed that stellar pulsations driven by the so-called kappa-mechanism is causing the star to continuously brighten or fade with two periods of 185 (+-13.5) days and approximately 400 days.
Does Betelgeuse have helium?
Betelgeuse has enough helium to stay in the red supergiant stage for about 100,000 years. Even after it runs out of helium, it will be able to fuse carbon into heavier elements for about a millennium.
Is Betelgeuse about to explode?
Betelgeuse is a red supergiant — a type of star that’s more massive and thousands of times shorter-lived than the Sun — and it is expected to end its life in a spectacular supernova explosion sometime in the next 100,000 years.
How hot is the core of Betelgeuse?

Can Supernova be predicted?
Distant ‘Requiem’ supernova will be visible again in 2037, astronomers predict. The supernova is visible thanks to a giant galaxy cluster that acts like a magnifying glass. A distant supernova previously imaged by the Hubble Space Telescope will be visible again from Earth in 2037, astronomers predict.
Does Sirius have helium?
With slightly more than twice the mass of the sun and just less than twice its diameter, Sirius still puts out 26 times as much energy. It’s a main-sequence star, meaning it produces most of its energy by converting hydrogen into helium through nuclear fusion.
What is the mass of Rigel?

Rigel/Mass
How far away is Betelgeuse from Earth in light years?
642.5 light years
Betelgeuse/Distance to Earth
Answer: Betelgeuse is 650 light years from Earth so it takes light 650 years to reach us . If the explosion happened in the Year 3000 AD, then we will see the light arrive in the year 3650 AD, 650 years AFTER the event occurred.
