Weekend Variety Wireless With Graeme Hill On Radiolive

This hour, Science Report with Matthew Egbert. Also, Neighbouring galaxies, otherwise known as 'Magellanic clouds', lie just beyond the Milky Way. Astronomer Dr Grant Christie joins Graeme Hill to discuss the Magellanic clouds images taken from Chile. These two "clouds", first described by Ferdinand Magellan are two dwarf galaxies very close to our much larger Milky Way Galaxy. Following The Gaia Projects second data release, precise positions of over 1.3 billion stars have been plotted- still being only about 1% of the Milky Way's stars. At the lower right of the map are stars of the Large and Small Magellanic Clouds. Solar minimum is where solar activity is least active in its cycle. So far in 2018 the sun has been blank almost 60% of the time, with whole weeks going by without sunspots. Today's sun, shown from NASA's Solar Dynamics Observatory, is typical of the featureless solar disk: sunspots are vanishing faster than expected. Forecasters have been saying for years that this would happen as th
