As we continue to discover the diversity of life on Earth, we are forced to stop and marvel at how tenacious and inventive life is. So, as we forge onward in our robotic explorations of other worlds, we shouldn't be too surprised to find other places where conditions seem to be right for life.

Different Worlds

We reveal the planetary enigmas on our doorstep and embark on the New Horizons voyage to photograph Pluto. Will our encounter with this tiny ball of ice and rock and the trillions of icy objects beyond it paint a clearer picture of how the planets came to be?

Terra Firma

This is the story of pioneering missions to neighboring planets and our first glimpses of their awe-inspiring terrains. From the giant lava plains of Venus to the volcanoes on Mars that dwarf Mount Everest, we journey around the rocky planets and then to the icy moons of Jupiter, Saturn and beyond.

Giants

For centuries the giant planets floated on the fringes of the solar system as distant objects in the eyepieces of astronomers. But in December 1973 mankind had its first close encounter with Jupiter. We chart the story of our discovery of these massive planets, Jupiter, Saturn, Uranus and Neptune.

Moon

Earth has a companion in space so large that it rules our nights, our months, our ocean tides. Why Earth should have such a moon is one of the deepest mysteries of the Solar System. We tell the story of how the Earth’s satellite became the unlikely object of desire of the two Cold War superpowers.

Star

For millennia humans have seen our star, the Sun, through the Earth’s atmosphere. But the Space Age has given us a new perspective that has revealed the many faces of the Sun in X-rays, ultraviolet/visible light, heat, and radio. We reveal hidden secrets of the Sun, like the power of solar wind.

Atmosphere

In 1971 a Russian spacecraft attempted to photograph Mars, but the planet did not cooperate. Since then, we've learned more about the atmosphere of the red planet, and what makes it similar to, but very different from, our own.

Destiny

The Sun created our Solar System and in a fit of cosmic cannibalism will engulf and destroy it. However, our Solar System will see many changes before the light of our star goes out. So, what will be happening with the planets over the next four billion years, before the Sun swallows us and them?

Black Holes

We’ve covered a lot of incredible stuff, but this week we’re talking about the weirdest objects in space: BLACK HOLES. Stellar mass black holes form when a very massive star dies, and its core collapses. The core has to be more than about 2.8 times the Sun’s mass to form a black hole. Black holes come in different sizes, but for all of them, the escape velocity is greater than the speed of light, so nothing can escape, not matter or light. They don’t wander the Universe gobbling everything down around them; their gravity is only really intense very close to them. Tides near a stellar mass black hole will spaghettify you, and time slows down when you get near a black hole — not that this helps much if you’re falling in.

Supernovas

Life is created in unimaginably large explosions called supernovas, scattering the elements formed in the heart of stars. What can they teach us about our origins?

Jupiter: Close Encounter

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.

The Search for Life: The Drake Equation

For many years our place in the universe was the subject of theologians and philosophers, not scientists, but in 1960 one man changed all that. Dr Frank Drake was one of the leading lights in the new science of radio astronomy when he did something that was not only revolutionary, but could have cost him his career. Working at the National Radio Astronomy Observatory in Greenback in Virginia, he pointed one of their new 25-metre radio telescopes at a star called Tau Ceti twelve light years from earth, hoping for signs of extraterrestrial intelligence.

Pluto's Heart

A voyage a decade in the making, the New Horizons probe has travelled to the end of our Solar System to reveal a world unlike any other, Pluto. Now, as it heads deep into the Kuiper Belt, those responsible for its magnificent journey share their fears, joy and hope for this piano-sized explorer.

Death of the Universe

This episode concentrates on how the universe was made in the Big Bang and how scientists predict it could end similarly as it continues to expand. Several theories are covered including the "Big Crunch" where the universe shrinks back to its original size, and the "Big Chill" with the universe slowly freezing to death.
