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.

In July 2022, the James Webb Space Telescope released its first images. They were visually stunning, and it was clear they provided more detail of stars, galaxies and planets than ever before. But for the scientists waiting on the data, this was just the beginning of their journey to discover what the new telescope would reveal. Since then, they have been working hard and publishing papers on all the data JWST has been sending back. Two years ago, just after the first images were released, Chris Lintott set off on a road trip to meet some of the scientists that were excitedly waiting on the first data. He wanted to find out what they hoped it could reveal. To mark the second anniversary Chris, along with fellow presenters Maggie Aderin-Pocock and George Dransfield, headed off to meet scientists old and new, to find out what the Webb Telescope has told us so far. Chris gives us a run-down of the highs and lows the Webb Telescope has been through and the other discoveries it has made. Maggie is off to Bristol University to revisit Dr Hannah Wakeford who has been using JWST data to reveal what interesting chemicals exoplanet atmospheres contain. George meets Professor Leigh Fletcher at the University of Leicester. When Chris met him two years ago, only one JWST image of Jupiter had been released. Now, he has data from all four of the outer planets of the solar system, and they have all thrown up surprises. JWST has revealed new jet streams on Jupiter and provided a greater understanding of its Galilean moons. Seasonal changes on Saturn have now been documented, and Uranus and Neptune have thrown up quirks that need another few years of work to understand. Chris also visits the University of Cambridge to meet Dr Sandro Tacchella, who has been part of a team looking back at some of the earliest galaxies. He explains what new light the JWST data can shed on ancient stars, and what that can reveal about how our cosmos formed after the Big Bang. Finally, our resident astronomer Pete Lawrence guides us through what there is to see in this month’s night sky, and how you too can look at some of the same targets as the James Webb Space Telescope – just not quite in the same level of detail!

No, it is not a planet :)

Most major geological processes require millions of year to become noticeable. Meteor impacts are exceptions which can cause comparable changes in seconds.

Since it explored Pluto in 2015, the New Horizons spacecraft has been zooming toward NASA's most distant target yet. Join the mission team as the probe attempts to fly by Ultima Thule, an object 4 billion miles from Earth.

Phil takes us for a closer (eye safe!) look at the two-octillion ton star that rules our solar system. We look at the sun's core, plasma, magnetic fields, sunspots, solar flares, coronal mass ejections, and what all of that means for our planet.
