In January of 2016, astronomers presented evidence that a giant planet may be lurking far beyond Neptune, quietly waiting to be found. If it exists, 'Planet 9' would be the first solar system planet to be discovered in over 170 years, with all due respect to the fallen Pluto. In this talk, we'll examine the case for Planet 9, learn about the latest efforts to detect it and figure out if it is going to kill us all. Hint: no.

The quest for ever-clearer views of the sky has driven astronomers to put telescopes in some pretty remote places, from arid deserts to the mountain tops and even the middle of Antarctica. Professor Keith Vanderlinde talks about his work with the 10m South Pole Telescope and why he undertook an 11-month "winterover" working in Antarctica.
