Lab notes: Tim Peake on falling back to Earth, 'baby' planets and driverless cars

Ground control to major Tim: how does it feel? "I was told that it would stop with a big jolt as the main chute opened, but in our case, it didn't," said Tim Peake as he recalled the moment when he feared his spacecraft's main parachute had failed to open. In related news, the discovery of two "baby" planets this week (awww) is exciting for a number of reasons, not least because they're still developing, giving us "a glimpse of planet formation as it occurs". And finally, researchers explore the moral dilemma of programming driverless cars.
