Hi..Stuart with the Show Notes for Series 19 Ep.24:

*New neighbouring galaxy discovered Astronomers have just discovered a new galaxy quietly lurking at the edge of the Milky Way. The newly found satellite is located just 391 thousand light years away and is the fourth largest galaxy ever detected orbiting the Milky Way.

*Earth currently being showered by supernovae debris The ashes of a recent supernova explosion are sprinkling down on Earth right now. The new data comes from traces of the isotope Iron 60 which was produced in the cataclysmic explosion of a nearby star in a supernova within the last few million years.

*New satellite launched to monitor the growing effects of global warming A new satellite has blasted into orbit as part of a growing constellation designed to monitor the growing impacts of human made climate change on the planet. The Russian Soyuz rocket carrying the latest Sentinel environmental satellite in the Copernicus constellation launched from the European Space Agency’s Kourou space port in French Guiana.

*Ancient tectonic activity was trigger for ice ages A new study has finally explained the link between the movement of the continental tectonic plates and the Earth’s two ice ages. The research claims a natural mechanism for carbon sequestration triggered both ice age events.
