Ep 99: The Unknown Solar System
from The Mr Science Show
You may think that with the Hubble Telescope, the Mars Rovers, the Huygens probe and even the Voyager missions launched way back in 1977, that there is little left for us to learn about our solar system. But this is far from the truth, and it seems that the more we learn, we more we realise how much we don't know. This week in our 99th show, I speak to Bianca Nogrady from New Scientist about the recent NS article The biggest mysteries of our solar system. The 6 biggest unknowns were: How was the solar system built? Why are the sun and moon the same size in the sky? Is there a Planet X? Where do comets come from? Is the solar system unique? How will the solar system end? Follow the links for discussions on the NS site about those topics. Listen to his podcast here.
