NASA's Solar And Terrestrial Relations Observatory Discovered Dimming Of Betelgeuse Red Giant Star

Betelgeuse is an red supergiant massive star of constellation orion. Astronomers have been monitoring the Betelgeuse star from last 25 years. The photometry data of Betelgeuse showed up it dimmed at southern hemisphere so astronomers believe that process happens by stellar sneeze.

When large amount of mass has been centered and clouds gas revolving around it then that region is called stellar sneeze.


Betelgeuse Star

Orion is a prominent constellation which located on the celestial equator. It is one of the most conspicuous and recognizable constellations stars in the night sky which visible from earth by naked eye.

Betelgeuse is a brighter star in Milky way galaxy and it's size is 700 times bigger than sun. it rhythmically brightening and dimming in every 420 days. Betelgeuse's surface is very unstable because it reached at the end of it's lifespan. If Betelgeuse be our sun then it would be swallow Mercury, Venus, Earth, Mars, asteroid belt and Jupiter.

Betelgeuse is dimming from the end of 2019 which is unusual because according to previous data it's dimming process started very soon only after 150 years. Betelgeuse star had lost about two-thirds of its original brightness and scientists said that it is time to become a supernova which totally vanish in 1 million years.

Scientists observation this star closely by help of Hubble space telescope and also they able to explore the surface and atmosphere of Betelgeuse by ultra violet ray. Researchers have found the brightest and hot material moving outward from the southern hemisphere of Betelgeuse. Unknown materials are turn into dark cloud and left from the star's surface then it totally vanished in interstellar space and it's speed is about 2 million miles per hour.

Senior astrophysicist Andrea Dupree of Harvard Smithsonian Center said that this unknown material is 4 times luminous and it's south hemisphere is forming a dense dust cloud which clearly It viewed from Earth if it happened at the north hemisphere of star we couldn't never know about it.

Betelgeuse is only visible from Hubble space telescope in night sky just before sunrise and rest of time it observed by NASA's Solar and Terrestrial Relations Observatory. STEREO is revolving around the sun in earth orbit and it is perfect instrument for keeping attention on Betelgeuse.
