Head beyond the Asteroid Belt for an out of this world experience. Welcome to Jupiter, home of high adrenaline adventure. Plunge into its mysterious depths. When you drop through the clouds it would get darker and hotter. At the center the temperatures are hotter than the surface of the sun and the pressures are unimaginably high.

Planets beyond our solar system are known to astronomers as exoplanets. They are at trillions of miles from Earth and yet, it might be possible to detect a faint signature of life in them. From the light of the stars they orbit that passes through the atmosphere of an exoplanet, it is possible to capture the chemical fingerprint of the elements in that atmosphere.
The fictional world Eden is orbiting not one star, but two. The light from its twin stars powers photosynthesis, pumping more oxygen into the atmosphere than in Earth, allowing life to thrive. Grazers are constantly alert to danger, because the canopy is home to predators perfectly evolved to live among the trees. In Episode 3, another topic are fungi and the role they could play on exoplanets. Ecologist Thomas Crowther talks about the role mycelial networks play in the Rothiemurchus forest in Scotland.

For all of human history, the Sun, our home star, has measured our days and our seasons while fueling all life on Earth. Yet it remains an enigma. NASA's Parker Probe Plus is on a mission to change that, flying through dangerous radiation to become the closest spaceship to orbit our Sun.
It's a journey to the center of our solar system, a mission to gather information about the most critical celestial body in the sky, our star.

Exoplanets, strange worlds outside our solar system. We're discovering the cosmos is full of alien planets. Alien worlds that challenge our understanding of planetary systems. Hellishly hot worlds, violently colliding worlds, worlds getting eaten by their stars. There's much, much more out there than we had ever imagined.
Exoplanets are shaking up our understanding of the universe. The cosmos is a chaotic array of the odd, the weird, and the wonderful. The more we find, the less we know.

Our world, our solar system, our universe, none of it would exist without a ghostly particle called the neutrino. They are our early warning system whenever there's trouble in the universe. Neutrinos trigger star-killing explosions, supernovas. Neutrinos can answer so many questions, from why do we exist to how was the universe created. Neutrinos can be the very reason that we exist at all. The more we understand these elusive particles, the more we can gain insight into how the universe works.

Chris Lintott and Maggie Aderin-Pocock report on the reaction to the dramatic announcement of the discovery of phosphine gas in the clouds of Venus, a gas that could be a sign of life. Venus remains an inhospitable and unlikely host. But if not Venus, where in the solar system is the best place to look for alien life? Chris and Maggie investigate the latest missions to Mars and the icy moons of Jupiter and Saturn. Away from the search for life, Pete Lawrencepreviews the best meteor showers of the year.
