Hi everyone, Stuart here with the Show Notes for Series 19 Episode 55.
*Strange new outer solar system body defies scientific explanation
Astronomers have just detected a new trans Neptunian object in the outer rim of the solar system on a strange highly unusual orbit. The discovery indicates the newly found object -- nicknamed Niku – has a retrograde and highly inclined orbit around the Sun.
*More evidence supporting the existence of a ninth planet in our solar system
Two new studies claim our solar system’s tilt could be explained by the existence of a ninth planet out beyond Neptune. The new research uses computer models to show how a hypothetical ninth planet of a specific mass and orbit would influence orbital plane or ecliptic of the solar system – causing it to tilt by six degrees in comparison to the Sun’s equator.
*Neutrino’s offer new clues into why we live a matter rather than antimatter universe
A new study of elemental sub atomic particles called neutrinos has provided scientists with new insights into why the universe is made up of more matter than antimatter.
*No evidence for the existence of a fourth kind of neutrino – the sterile neutrino
Meanwhile, efforts to find a fourth type or flavor of neutrino -- known as the sterile neutrino -- have failed to identify the long hypothesized particle. If discovered, the sterile neutrino could have helped resolve the long standing mystery of the origin of dark matter as well as the matter/antimatter asymmetry in the universe.
We check out the August night skies with Jonathan Nally from Australian Sky and Telescope Magazine.
