As you might have seen it, @LIGO has detected some weird gravitational waves. I took more than a day to take the time to read everything about it. So, is this new candidate related to #Betelgeuse?
Let's go for a little thread!
Contrarily to what some people said, Betelgeuse is NOT in the 90% zone for the GW. As you can see, it is next to it, probably in the 95% zone. So we cannot exclude that it comes from Betelgeuse, but it is unlikely.
Also, no unusual gamma-rays...

1/10 All eyes on #Betelgeuse these days. What’s happening to this well-known star in the constellation of #Orion?
2/10 Normally one of the brightest stars in the sky, it’s now fainter than ever before in recorded history.
3/10 Astronomers think the star is preparing to blow, going #supernova. Think cosmic time scales though. This artist’s impression shows #Betelgeuse shedding its material. eso.org/public/images/…

Why do we know #Betelgeuse may go #Supernova within the next few 100000 years, but most likely not soon? And why are we sure the Sun will be a safe star for Billions of years?

A brief primer #thread to Stellar Evolution. 1/

Sun: SDO. Betelgeuse: ESO/ALMA

First thing to know is: stars are not all alike. They are big, small, bright, dim, have different colors and die different deaths. The quantity at the root of their diversity is their MASS. Stars have masses between roughly 0.1 & 100 times the Sun’s mass. Large ones are rare.2/
Here is the fundamental diagram of stellar evolution. It’s called the Hertzsprung-Russell Diagram (HRD). The further left you go, the hotter stars become. The further up you go, the brighter stars become. 3/

#SIRIUS the RED giant star #Betelgeuse. Matthew 24 says the Sign of the Son of man will appear in the skies to warn people to be ready for #Rapture & #SecondComing of Jesus. Jesus stood among 7 stars in Revelations to warn the 7 churches and mankind

Betelgeuse is a MASSIVE star that is RED color because it is nearing the end of its life span. The bright red color symbolizes a blood sacrifice of Yeshua for us! The right shoulder signifies strength or triumph. In Orion, the right shoulder and hand signify “The Coming Branch.”
Jesus in last days as #ORION CONSTELLATION star Betelgeuse is the Brightest Star in constellation Orion called Alpha Orionis. God the Alpha and Omega uses symbols, signs and wonders seen in Jesus Christ.
