Observation 4.2: Astronomy Cast Episode 156

This episode spoke largely about the impact of foreign stars. An interesting idea which was presented was that the explosions of any star will have some effect on our planet, no matter the distance of the star itself. This is through the influence of effects such as Gamma rays. Additionally, this episode went into the great variation which can be found in stars, from a white dwarf as small as our moon to a star as gargantuan as VY Canis Minoris.
