Spacetime With Stuart Gary

*A possible cradle of life discovered on Mars Evidence of massive ancient sea floor hydrothermal vent deposits have been discovered on Mars. Hydrothermal vents found on the mid ocean ridges of Earth, pump a rich chemical soup into the surrounding oceans, which many scientists believe could be where life on Earth began. *Chemical signatures for life discovered near and far Freon-40, a chemical signature of life has been detected -- both around a distant star -- and much closer to home – in a comet orbiting the Sun. The discovery includes the first ever detection of a saturated organohalogen chemical compound in interstellar space. *Cosmic rays from distant galaxies A fifty year long debate has finally been resolved with confirmation that the highest energy cosmic rays originate from sources far beyond our galaxy. The findings are based on the uneven distribution of high energy cosmic rays bombarding the Earth from different positions across the sky. *Mysterious Dimming of Tabby's Star May Be Caused by Dust Ast
