This shows the dramatic drop off of luminosity for the star Betelgeuse. Here’s Betelgeuse. A Super Giant star located 600 light years away. It’s known as Orion’s shoulder. It was once the 11th brightest star in the sky. Now it’s lost over 20% of it’s visible illumination and we’re waiting, wondering. #lifeofastar #redgiant #mainsequence #supernova #neutrinos #collisioncourse I have Ed Guinan from Villanova on Revolution Radio tomorrow night from 8-9 pm on Collision Course @ freedomslips.com https://www.instagram.com/p/B7xNIQrJhB_/?igshid=pquybiq4eb2x
