"The Planets" is a five-part series telling the extraordinary story of all eight planets and Pluto.

PBS journeys through the solar system to explore NOVA’s “The Planets.”

Inside Look: "The Planets"

Among the stars in the night sky wander the eight-plus worlds of our own solar system—each home to truly awe-inspiring sights. Volcanoes three times higher than Everest, geysers erupting with icy plumes, cyclones larger than Earth lasting hundreds of years.

The life of our solar system told in five dramatic stories spanning billions of years.

The rocky planets—Mercury, Venus, Earth and Mars—were born of similar material around the same time. Yet only one of them supports life. Were Earth's neighbors always so extreme? And is there somewhere else in the solar system life might flourish?

The rocky planets have similar origins, but only 1 supports life. Was it always this way?

The four planets closest to the sun, called the rocky planets, were born from the same material in the same era. But they couldn’t be more different: Tiny Mercury is the runt of the litter, almost like a moon. Venus is devilishly hot, and Mars is a frozen desert world. Only on Earth do we find the unique conditions for life as we know it. But why only here? Were Earth's neighbors always so extreme? And is there somewhere else in the solar system life might flourish? (Premiered July 24, 2019)

Mars was once a blue water-world studded with active volcanoes. But when its magnetic field and protective atmosphere faded, it became the frozen desert planet we know today. With so many necessary elements in place, did life ever form on Mars?

Before it was a dry planet, Mars was a wet world that may have hosted life.

Much like Earth, Mars was once a water world, rich with the building blocks for life. But it didn’t last. Was there enough time for life to take hold on the Red Planet before it dried out?

Mars once had rains, rivers, and in the northern hemisphere, a vast sea.

Mars, the Red Planet, Was Once Blue

What's so marvelous about Mars? Here are five facts about the Red Planet.

Getting to know our red celestial neighbor.

Five Facts About the Red Planet

The Red Planet was once a vibrant blue water-world, home to raging rivers, active volcanoes, and even an ocean. But as the young planet’s core cooled, its magnetic field and protective atmosphere faded, eventually exposing it to the wrath of the sun. With its volcanoes extinguished and its water lost to space, Mars became the frozen desert planet we know today. But if it once had many of the ingredients necessary to form life, how far along might that process have gotten? (Premiered July 24, 2019)

Jupiter’s massive gravitational force made it a wrecking ball when it barreled through the early solar system. But it also shaped life on Earth, delivering comets laden with water—and perhaps even the fateful asteroid that wiped out the dinosaurs.

About 5 billion years ago, as our sun forms, most planets around it are still dust. But Jupiter's core already begins to grow.

Jupiter formed long before most other planets around it did.

Jupiter, the First Planet to Form in our Solar System

What's so special about Jupiter?  Here are five facts about the planet that's home to the "Great Red Spot."

Jupiter is more than the biggest planet in our solar system—it's also the oldest.

Five Facts About the Biggest Planet in our Solar System

Jupiter is not just the oldest planet orbiting the sun—it’s also the largest. So when the young gas giant went on a rampage through the inner solar system, it shaped the fate of everything in its path. Speeding towards the Sun, Jupiter’s massive gravitational force hurled debris into interstellar space, stunting the growth of would-be planets. Earth might have been doomed had Saturn not pulled Jupiter back. Today, Jupiter resides in the outer solar system, where its gravity bends the paths of asteroids and stokes volcanic activity on its moon Io. But it could one day wreak havoc again.

Five Facts About the Ringed Gas Giant Planet

Over the past 40 years, a handful of space probes has given us glimpses of Saturn. But NASA’s Cassini, which explored the gas giant’s realm for 13 years, delivered the most breathtaking new insights. NOVA takes you inside Cassini’s epic journey as it makes stunning discoveries: Saturn’s rings are younger than the dinosaurs and may be remnants of an ice moon. And geysers erupting ice and gas on the moon Enceladus show that it could have all the ingredients for life. But to protect it, the Cassini mission team makes a bittersweet decision.

Despite Neptune's distance from the Sun, the Voyager mission discovers that Neptune is warmer than its neighbor, Uranus. And, it has the strongest winds of any planet in the Solar System.

Neptune has swirling clouds and strong winds. Can scientists figure out why?

Over a billion miles from the sun, beyond the rocky inner planets and the gas giants, lie the ice words—Uranus and Neptune. NOVA takes you inside the missions that rewrote the story of the outer solar system: NASA’s Voyager 1 &amp; 2 capture Neptune’s supersonic winds, and rings around a tipped-over Uranus. And when New Horizons flies by Pluto in 2015, it reveals jagged ice mountains and an underground ocean. (Premiering August 14 at 9 pm on PBS)

Among the stars in the night sky wander the eight-plus worlds of our own solar system—each home to truly awe-inspiring sights. Volcanoes three times higher than Everest, geysers erupting with icy plumes, cyclones larger than Earth lasting hundreds of years. Each of our celestial neighbors has a distinct personality and a unique story. In this five-part series, NOVA will explore the awesome beauty of “The Planets,” including Saturn’s 175,000-mile-wide rings, Mars’ ancient waterfalls four times the size of any found on Earth, and Neptune’s winds—12 times stronger than any hurricane felt on our planet. Using unique special effects and extraordinary footage captured by orbiters, landers and rovers, we’ll treat viewers to an up-close look at these faraway worlds. We’ll stand on the dark side of Pluto, lit only by the reflected light of its moons, watch the sun set over an ancient Martian waterfall, and witness a storm twice the size of Earth from high above Saturn. And, we’ll reveal how each of them has affected our own planet: Earth. (A five-part series premiering July 24, 2019 at 9 pm on PBS)

What risks does cannabis pose to the developing brain? How much do we know about its potential medical benefits? As cannabis becomes socially accepted, scientists are exploring its long-term health consequences.
