All life on Earth started as single-cell bacteria and stayed like that for two billion years. So even if we do find alien life out there, what are the chances of that life being complex like us? Astronaut host – Mae Jemison.
After 665 weightless days in space, NASA's most experienced astronaut, Peggy Whitson, smashes through the atmosphere on her last journey home to planet Earth. With unprecedented filming on board the ISS during Peggy's final mission and with the support of our other featured astronauts, we reveal how their time in space transforms their understanding of our planet's wonders, insights that will change our perspective, too. There is no place like home. Or is there? Just how strange is our rock, and is it really unique in the universe? Astronaut host – Peggy Whitson.

Scientists using the Hubble Telescope study vivid images from 12 billion and more light years away and observe that many galaxies cluster together like -- soap bubbles! Analyzing factors like dark matter and gravitational lensing, how can astronomers confirm this amazing bubble structure?
What would happen if the sun took out our electrical power grid for an entire year? It may sound like the plot of a sci-fi movie, but this doomsday scenario could actually happen. Despite its calm appearance, the sun is a violent place, constantly releasing huge masses of energy known as coronal mass ejections. These storms have hit the earth before. The last big one struck more than 150 years ago in the Victorian era taking out worldwide telegraph service. The impact of a similar storm would be far more destructive in our modern age of hyper-connected telecommunication and total reliance on electricity and electronics. Fortunately scientists and engineers are building the world's largest solar telescope and launching the first ever spacecraft to fly to the sun to help us predict these potentially devastating events - and prepare for them.

There is a new kind of weather to worry about, and it comes from our nearest star. Scientists are expecting a fit of violent activity on the sun which will propel billions of tonnes of superheated gas and pulses of energy towards our planet. They have the power to close down our modern technological civilisation - e.g. in 1989, a solar storm cut off the power to the Canadian city of Quebec. Horizon meets the space weathermen who are trying to predict what is coming our way, and organistions like the National Grid, who are preparing for the impending solar storms.
Can Jupiter unlock the secrets of Earth’s formation? How did a team engineer a spacecraft to endure a toxic mix of radiation and gaseous turbulence? After a five-year journey, the moment of truth is finally here. Jupiter: Close Encounter delivers a comprehensive, hour-long look at the unprecedented, amazing, and utterly extreme journey of NASA’s heavily armoured Juno Spacecraft on an odyssey to the largest planet in the solar system. Anchored by DAILY PLANET Co-Host Dr. Dan Riskin from the NASA Jet Propulsion Laboratory (JPL) in Pasadena, California, Jupiter: Close Encounter follows NASA’s Juno Spacecraft mission as it attempts to enter a “polar orbit” around the king of the the solar system for the first time ever on July 4. The landmark mission will study the planet’s spectacular auroras, seek the inner-most core, and wade into Jupiter’s Great Red Spot. The gripping one-hour special introduces viewers to the dedicated and incredible team behind the high stakes-mission – scientists determined to provide new answers to the mystery of the solar system, Earth, and life itself.
