SpaceTime with Stuart Gary Series 19 Episode 40 - Study predicts a universe crowded with black holes
Hi everyone...Stuart with the Show Notes for Series 19 Episode 40:
*Study predicts a universe crowded with black holes One of the most complete models ever developed of the distribution of matter across the universe predicts hundreds of massive black hole mergers must be occurring throughout the cosmos each year. The new study claims these mergers should be observable with new second generation Laser Interferometer gravitational wave detectors now being developed.
*Pluto may have a subsurface ocean Scientists say ongoing geological activity on Pluto seen by NASA’s New Horizons spacecraft could be caused by the partial freezing of a subsurface ocean that likely still exists today. The new study claims models show recent geological activity on Pluto could have be driven solely by phase changes in the dwarf planet’s ice shell without the need for gravitational tidal activity or the radioactive decay of exotic minerals.
*The discovery of an unexpected mineral on Mars may mean a rethink of Martian evolution NASA's Mars Curiosity rover has discovered an unexpected mineral in a Martian rock sample taken in Gale Crater, which may alter sciences understanding of how the red planet evolved. The six wheeled car sized rover has been exploring sedimentary rocks within Gale Crater since landing there back in August 2012.
*Ariane 5 carries new payload launch record on its fifth flight of the year Arianespace has carried out its fifth Ariane five launch of the year setting a new launch payload mass record of 10,730 kilograms.
*Mission VA230 blasted off from the European Space Agency’s Kourou Spaceport in French Guiana placing two telecommunications satellites into geostationary transfer orbits.
*China launches navigation satellite A Chinese Long March 3c rocket has successfully blasted off from the Xichang Satellite Launch Centre in south western China’s Sichuan province placing the latest member of Beijing’s Beidou or compass satellite navigation system into orbit. China is developing its own satellite navigation system with a 35 spacecraft constellation to rival the American GPS, European Galileo, and Russian GLONASS systems by the end of next year.
*New Shepard, flight four Blue Origin’s New Shepard suborbital rocket has successfully completed its fourth test flight at the company’s western Texas launch facility. Blue Origin plans on using New Shepard to carry up to ten space tourists at a time to altitudes of 100 kilometres -- the official start of space -- with the first paying passengers flying in 2018.
