NASA's Cassini explored Saturn for over a decade, making incredible discoveries about its rings, storms, and moons. Here are the spacecraft's final moments.

NASA’s Cassini explores Saturn for 13 years, looping through its icy rings and flying by its moons. The probe captures stunning ring-moon interactions, but when it finds the ingredients for life on the moon Enceladus, a bittersweet decision is made.

Saturn is one of the most recognizable planets in our solar system. Here are five cool facts.

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.

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

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

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 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?

Working with scientists, "The Planets" production team created more than 2.5 hours of CG and VR effects to visually represent the physics of our Solar System.

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?

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?

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

What else makes the second planet in our solar system interesting?

Mercury is the smallest planet in our solar system. But what else makes Venus's next door neighbor unique?

Ingeniously, by using part of the rocket itself as the impactor, scientists make room for a separate spacecraft—one that follows a few minutes behind, flies through the ejected material to analyze its contents, and hurriedly sends the data back to Earth before smashing into the Moon itself.

Fifty years after humans first set foot on the Moon, new scientific discoveries are fueling excitement for a return to the lunar surface—this time, perhaps, to stay. Join the scientists and engineers working to make life on the Moon a reality.

Samples from the Apollo mission support an intriguing new theory for how the Moon formed called the “Giant Impact Hypothesis”
