SpaceTime with Stuart Gary Series 19 Episode 36 - Small blue galaxy could shed new light on Big Bang
Hi, Stuart with the Show Notes for Series 19 Episode 36.
*Small blue galaxy could shed new light on Big Bang Astronomers have discovered a faint blue nearby galaxy which could shed new light on the early history of the universe. The galaxy contains similar proportions of chemical elements to those thought to have been in existence shortly after the big bang.
*Elliptical galaxies not formed by merging A controversial new study claims big elliptical galaxies were formed in very ancient times through a process of local -- in situ -- star formation. The new findings are based on new computer models which contradict existing galactic evolution hypotheses involving ellipticals forming through mergers of smaller spiral galaxies.
*America’s next space plane on order The United States is moving forward with plans for a new reusable winged spaceplane capable of delivering satellites and other payloads into orbit on a daily basis with turnaround times of just 24 hours between flights. The new vehicle will provide the first stage of a new multi-stage rocket carrying one or more expendable upper stages which will deploy small payloads of up to 2.3 tonnes into low earth orbit.
*NASA's Juno Spacecraft Crosses Jupiter/Sun Gravitational Boundary NASA's Juno spacecraft has crossed the Jupiter/Sun Gravitational Boundary an important milestone in its mission to study the solar system’s largest planet. Once in orbit, the spacecraft will spend at least 20 months circling the Jovian world 37 times, skimming to within 4300 kilometers above the planet's cloud tops.
