A Beautiful Planet is a breathtaking cinematic journey that offers a rare perspective of our planet as seen from space. Narrated by Jennifer Lawrence and filmed in stunning IMAX 3D, the documentary takes audiences aboard the International Space Station alongside NASA astronauts. Through awe-inspiring visuals, it showcases Earth’s vibrant landscapes, diverse ecosystems, and the delicate balance that sustains life. The film not only highlights the planet’s natural beauty but also draws attention to the environmental challenges we face, including deforestation, pollution, and climate change. By juxtaposing scenes of Earth’s splendor with the visible impacts of human activity, the film delivers a powerful reminder of our shared responsibility to protect our home. More than just a space documentary, it is a moving call for global unity and stewardship of the planet.

There is a hellish planet in our solar system; covered in thick dense clouds and roasted by colossal temperatures. Incredibly this is a vision of Earth's future. To understand how our world will be destroyed we need to look at Earth's evil twin Venus.

It’s been conjectured that the center of the Milky Way is swarming with tens of thousands of black holes. And now we’ve actually seen them.

Today we’re rounding out our planetary tour with ice giants Uranus and Neptune. Both have small rocky cores, thick mantles of ammonia, water, and methane, and atmospheres that make them look greenish and blue. Uranus has a truly weird rotation and relatively dull weather, while Neptune has clouds and storms whipped by tremendous winds. Both have rings and moons, with Neptune’s Triton probably being a captured iceball that has active geology.

Now that we’re done with the planets, asteroid belt, and comets, we’re heading to the outskirts of the solar system. Out past Neptune are vast reservoirs of icy bodies that can become comets if they get poked into the inner solar system. The Kuiper Belt is a donut shape aligned with the plane of the solar system; the scattered disk is more eccentric and is the source of short period comets; and the Oort Cloud which surrounds the solar system out to great distances is the source of long-period comets. These bodies all probably formed closer into the Sun, and got flung out to the solar system’s suburbs by gravitational interactions with the outer planets.

Professor Brian Cox fulfils a childhood dream by going behind the scenes at Nasa's Jet Propulsion Laboratory (JPL), mission control for Mars 2020 – one of the most ambitious missions ever launched that may finally reveal if life ever existed on the red planet. In 1980, a young Brian Cox wrote to JPL asking for photos from some of their missions to the planets. The pictures they sent him from Voyager and the Viking mission to Mars were a source of inspiration that set him on the path to becoming a physicist. Now, over 40 years later, he has been granted privileged access to JPL, including key mission areas that are usually off-limits to film crews. Brian spends a week following the team who guide the Perseverance rover and the Ingenuity helicopter - the first powered aircraft ever sent to another planet - across the surface of Mars during a critical stage of the mission. Perseverance's goal is to search for signs of long extinct life on the surface of Mars in an area called Jezero Crater, which, 3.8 billion years ago, was filled by a vast lake. If it finds evidence of that life, it could change everything we know about life in the universe - and even transform our understanding of our own origins.
