Betelgeuse Star:
Scientists resolved the mystery behind the sudden dimming of the supergiant Betelgeuse star and dismissed theories that suggested that the star might be entering the last stage of its evolution.
- Betelgeuse star is a red supergiant starwith a distinctive orange-red hue.
- It is roughly 10 million years old and much younger than Sun.
- It is around 700 light-years away from the Earth.
- It is located in the Orion constellation.
- It is particularly easy to spot because of its brightness; it is often the tenth-brightest star in the sky.
- It is also one of the largest stars visible to the unaided eye.
- While it is large and bright, Betelgeuse isn’t actually that hot, with a surface temperature of about 6,000 degrees Fahrenheit (over 3,300 degrees Celsius).
- Betelgeuse has been classified as a “semiregular variable star,” which is a type of variable star that periodically waxes and wanes in brightness and occasionally undergoes irregular light changes.
- Betelgeuse, typically, has a 400-day cycle as well as a longer cycle that stretches about 5 years.
