On this day in 1910 - October 19th - Indian-American astrophysicist and Nobel laureate Subrahmanyan Chandrasekhar was born.He's known for his work in stellar evolution, including the Chandrasekhar Limit. That is the dividing line between the mass of a star that has spent its nuclear fuel and will collapse into a white dwarf and one massive enough to go out with a bang - a supernova. It's about 1.4 times the Sun's mass.

An amazing planetarium Mona, and a fascinating experience for anyone in the area...worth giving the local mountains and lakes a miss for a few hours.
It was all upgraded to state of the art a few years ago, and although the shows are only in German the projections, and real time simulations, speak for themselves really so don't need words.
Of course the Deutsches Museum is anyway one of those places where one can happily spend days and never get bored, lost track of the number of times I've visited.

Francine, it sounds splendid. Many decades ago I was in Munich briefly on the way to somewhere else. So haven't seen the Deutsches Museum. It sounds great.
