Cosmic collisions and Type II Supernova and Mass Loss right before blowing up

 

Today I am sharing two summaries from two papers:

 Hubble sees asteroids colliding at nearby star for first time LINK 

 Dance to Demise—How Massive Stars May Form Dense Circumstellar Shells before Explosion LINK

Please head over to EadsyAstronomy for the video and/or written review. LINK

The second article is very interesting and I wonder if after going through it if the Great Dimming Betelgeuse experience in late 2019 through April 2020 was a result of a pulsation within the star resulting in the mass loss of dust and particles that blocked the star and IS that a sign that Betelgeuse is closer to its end? Will it experience further pulsations and thus more great dimmings? A few questions I had after going through the article. Head on over and let me know what you think. 

Orthoscopic Eyepieces: Minimalists with Great Benefits

 

A quick review over on EadsyAstronomy of my Orthoscopic Eyepieces, the University HD Orthos and the Baader Classic Orthos, their strengths, weaknesses and why I use them. They are OUTSTANDING for lunar, planet and double star splitting. They bring out contrast in their simple 4 element design and the cost is fantastic (the Baader's are available new, the University HD are not, they are on the used market if you can find them). I also use them on faint deep sky objects though the limited field of view is hard if you are nugging as I do and don't use tracking. Head over to EadsyAstronomy to see the video review or written review LINK. 

And yes, I am a huge fan of these eyepieces and think every visual observer should have at least the 12mm, the 6mm and if they can afford it, the 4mm for those nights of nights!
