Stream Episodes on demand from www.bitesz.com or www.spacetimewithstuartgary.com (both mobile friendly) *The closest ever stellar orbit seen around a black hole Astronomers have discovered what appears to be the tightest ever stellar orbit around a black hole. The findings could help astronomers better understand the strange gravitational dynamics around stellar mass black holes. *A new study of Gamma-ray flashes emanating from tropical storms Scientists have discovered that a storm’s size and intensity doesn’t affect its production of terrestrial gamma-ray flashes – some of the highest energy event generated on Earth. NASA scientists analysed dozens of terrestrial gamma-ray flashes launched by the largest and strongest weather systems on the planet: tropical cyclones, storms, hurricanes, and typhoons. *Scientists create negative mass Physicists have created a fluid with negative mass – which they claim is exactly as mind-bending as it sounds. It means that unlike just about everything else in the universe -- if you push it – instead of moving in the direction being pushed – it moves in the exact opposite direction. If you're enjoying SpaceTime, please help out by sharing and telling your friends.
