The Help

The Sky at Night looks back at the last ten years of astronomy and ponders the most significant milestones and revelations. With the help of six distinguished astronomers, Chris and Maggie consider the state of astronomy in 2020 and wonder what new, exciting discoveries await us across the rest of the decade, as a host of new ground and space telescopes come online. Astronomer Royal Lord Martin Rees is among the guests to walk along the Astronomical Wall of Discovery in this one-hour special.

Maggie Aderin-Pocock and Chris Lintott look back at some of the biggest stories featured on the programme in 2020, with the help of special guests who have chosen their favourite moments. From the launch of Solar Orbiter to the discovery of phosphine on Venus, the team relive the astronomy highlights of a highly unusual year.

During months of having to stay at home, millions of us have swapped the gym for our living room. The numbers doing home workouts has doubled in a year. But exactly what kind of exercise should we be doing, how much of it, and how often? Journalist and blogger Mehreen Baig used to hit the gym four times per week, but now her fitness regime has gone entirely DIY. She wants to use the latest science to make sure she is getting maximum return for her effort.

For the BBC series ‘The Secret Life of Elephants’ we’ve revealed the elephant’s hidden world – the depth of their emotions, their remarkable intelligence, and the intimate complexities of their family life. We spent three months in Kenya, filming the elephants and following the work of Iain Douglas-Hamilton and the Save the Elephants research team. We wanted to tell the stories of individual elephants, which meant we spent every hour from dawn till dusk finding and following our stars across the Samburu reserve. We focussed on the most dramatic moments in their lives – a calf from the day of her birth, a bull using tactics to win a mate, a matriarch making decisions to protect her family. We followed the research team on missions across northern Kenya to protect the elephants; we see them helping a community terrorised by crop raiding bulls, uncovering an outbreak of poaching which killed two of their best known elephants, and tracing the new dangers on ancient elephant migration routes.
After weeks of hard work, we were rewarded with astonishing glimpses into the elephant’s lives. But we couldn’t have imagined that we’d become so directly involved in a life or death operation to save a baby elephant’s life.

A manor is rigged with surveillance cameras and contributors fitted with observational devices.

From inside an observational room, Dr. Michael Mosley and a team of experts analyse their every move.

Professor Mike Wooldridge asks: what is artificial intelligence? He compares how AI works and learns with how the human brain functions. Exploring the roots of AI, Mike reveals how Alan Turing devised the Imitation Game – a test of whether a machine answering a series of questions could pass as a human. The audience in the lecture theatre play a real-life version of the game to find out if AI can pass this test today.

This series helps teachers demystify physics by showing students what it looks like. Field trips to hot-air balloon events, symphony concerts, bicycle shops, and other locales make complex concepts more accessible. Inventive computer graphics illustrate abstract concepts such as time, force, and capacitance, while historical re-enactments of the studies of Newton, Leibniz, Maxwell, and others trace the evolution of theories.
