Huge red star might explode soon and next few weeks are very critical



Betelgeuse, a supergiant star, 10th brightest star in our night sky is getting dimmer and dimmer. Astronomers are wondering that they may be in for a treat, to observe the process of the collapse and it becoming a supernova. Few more reasonable explanation are also on the table. Astronomers are working very hard on these findings and in the end of this month we may have an answer to that continuous dimming. 



Edward Guinan an astronomer from Veteran Villanova University has been watching Betelgeuse for decades and has reported that since the start of this month the star appears to be "the least luminous and coolest yet measured from our 25 photometry.

Amongst astronomers its a widely known fact that Betelgeuse has no more than 100,000 years left to live and could start its death suffering at any moment. When it under goes the process of supernova, astronomers are expecting a dramatic light show that could  appear to be brighter than a full moon that might last for few weeks. Last time when humanity witnessed such an astronomical event was the 17th century.

But according to the astronomer Tony Phillips as he pointed out on Spaceweather.com, the sudden dimming could also be a result of a giant Sunspot or clouds of stellar dust.

Maybe the star is just doing its thing, and that could be a boring explanation.Look, Betelgeuse is a common variable star in the Orion constellation that pulsates for many times in his lifetime.

"This whole episode may be a deeper-than-average pulsation, and maybe the supernova watch can be called off," Tony Phillips said.
According to the most recent data from Guinan's team shows that the star could be suffering through an extended 430-days of pulsation. If that is whats happening, it should reach its dimmest point on 21 feb. (could be a margin of error of a week or so) 

Moreover, Guinan's team realizes that Betelgeuse still appears to be even dimmer than it should be during such a extend pulsation. This could mean that there are many factors that could be resulting in the dimming of the supergiant star. 

"So something very unusual is going on." Guinan says. 

Whatever happens to Betelgeuse, astronomers will be observing it very closely to see if it finally begins to lighten up in the next months. If not, supernova sight is likely on the way.
