Stream Episodes on demand from or (both mobile friendly) *Early Galaxies dominated by ordinary rather than dark matter A new study has found that early galaxies were dominated by ordinary matter rather than the dark matter which dominates galaxies today. The findings mean dark matter – which makes up around 80 percent of all the matter in the universe today – was far less influential in massive, star-forming galaxies during the peak epoch of galaxy formation, 10 billion years ago. *How ghostly neutrino particles could improve sciences understanding of the universe A new study claims one type of neutrino may comprise exactly equal amounts of two other types of neutrinos. The findings by scientists working with the IceCube Neutrino Observatory at the South Pole could help physicists better understand the universe. *Earth probably began with a solid shell A new study claims Earth probably began as a single solid shell which broke apart later to form the planet’s characteristic individual tectonic plates. The findings could help settle a longstanding debate about the origins of plate tectonic on Earth. *Dragon returns to Earth, concluding tenth resupply mission. The SpaceX CRS-10 Dragon cargo ship has splashed down safely in the North Pacific Ocean off the Californian coast. 320 kilometres south west of Long Beach. The capsule was loaded with over two tonnes of experiments and equipment being returned to Earth from the International Space Station. *New Telecommunications satellite launched Following an earlier delay due to high winds, SpaceX has successfully launched a new telecommunications satellite into orbit. The spectacular night time launch from space launch complex 39A at the Kennedy Space Centre at the Cape Canaveral Air Force base in Florida was the third Falcon 9 launch of the year and the second off the historic former Space Shuttle and Saturn 5 Apollo moon rocket era launch pad.
