Some questions
So far we've been subjected to gamma ray Burst ( that would probably be
fatal to civilizations living near by one), Magnetstars, Eta Carina , an exploding star whom astro-physist think might be acting has a huge ultraviolet laser, Black holes, Neutron stars, Novas and Supernovas. I'm wondering ...how close can some stellar phenomena has to be before it can represent a threat to life on this planet,and what's a safe distance that would provide the people on this planet a spectacular light show but wouldn't represent a danger to life here. Are there any particular candidates that we should look out for? Second question, I used to look at pictures of galaxies and marvel that all that white hot gaseous looking stuff you see in a picture of a galaxy were stars. Now I'm wondering if alot of that white hot "stuff" you see when looking at a galaxy is just what it is ..white hot gas. Can the stars in a picture of a galaxy be spotted individually, or are they truly too numerous too count. "When I die, I would like to go peacefully in my sleep, like my grandfather did. Not screaming and yelling like the passenger in his car."
