This is the story of the James Webb Space Telescope, told by the people who have devoted their lives to it. It is the world’s largest, most advanced, and most expensive telescope, and building it has been fraught with challenges. But it will all be worth it if the December 2021 launch is successful.

The James Webb Space Telescope will go where no other telescope has gone before. This is the epic story of the scientists who have devoted their lives to developing it.

To the Moon and Beyond

In just one generation, our ability to search for planets beyond our solar system has transformed. With modern techniques and telescopes, planetary scientists have found thousands of exoplanets in our universe, and many of them have the perfect conditions for life. Are we about to find Earth’s twin?

For decades, scientists have dreamed of finding life on Mars. But despite their best efforts, no signs of life have been found. Could that be about to change? This is the story of the scientists and engineers behind Perseverance: the rover that could change our view of Mars forever.

No sign of life has been found on Mars – yet. This is the story of the scientists and engineers behind Perseverance: the rover that could change our view of Mars forever.

Finding Life on Mars

This is the story of two of the biggest scientific breakthroughs of the 21st century, told by the incredible scientists who made them happen. The first is LIGO’s measurement of gravitational waves coming from a black hole merger, and the second, the Event Horizon Telescope’s image of a black hole.

This is the story of black holes and the incredible scientists of the LIGO and Event Horizon Telescope Collaborations who made ground-breaking new measurements of them.

Chasing Black Holes

Scientists on the BICEP and Planck missions are attempting to solve a mystery about the earliest moments of our universe, by searching for patterns in the cosmic microwave background. If successful, the missions will help to answer the biggest question anyone can ask: how did our universe begin?
