S2018 E4 Gaia: A Galactic Revolution

本集简介

For past three and a half years, ESA's Gaia Space telescope has been mapping the heavens in unprecedented detail. At the end of April 2018 it released precise data on over 1.3 billion stars in the Milky Way showing how they move over time and their distance from Earth. Maggie and Chris reveal some of the most surprising initial findings, from the discovery of wandering black holes, hyper velocity stars and 'transient phenomena' to a brand new age map of the Milky Way and concrete evidence of how our galaxy formed.

Mars: Red and Dead?

Maggie Aderin-Pocock and Chris Lintott reveal the latest results from Nasa's Curiosity and Esa's ExoMars TGO missions that are attempting to find signs of life on Mars. Maggie visits the Airbus 'Mars Yard' to find out how the next lander heading to Mars is being built to survive the planet's incredibly hostile environment. And the team asks - if Mars is a dead planet, could the first life on Mars be humans? Chris talks to Andy Weir, author of The Martian, about whether a manned mission to Mars is just a fantasy.
