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”

Watch a ten of clubs transform into an ace of hearts in this magic trick, which demonstrates “change blindness,” a phenomenon that causes gaps in visual.

In a first, researchers found and photographed two newborn planets after spotting its young sun 375 light-years away.

Planet Nine’s existence is not the first time astronomers have predicted a planet they couldn’t see. Clyde Tombaugh was looking for Planet X when he accidentally found Pluto. After Voyager 2 flew by Neptune in 1989, new calculations determined there was no Planet X. But three years ago, a disturbance was detected at the far reaches of the Solar System.

Follow two astronomers, Mike Brown and Konstantin Batygin, as they’re on the hunt for Planet Nine — a hypothesized ninth planet at the edge of our solar system.

Two astronomers argue that the farthest objects in the Kuiper Belt are being pushed and pulled by the gravity of Planet Nine, a giant planet orbiting over 10 times farther from the Sun than Neptune. If they find it, it’ll be the first real expansion of the Sun’s planetary album in 170 years.

This robot might look like a Furby. But, using artificial intelligence, it can learn to understand a child's emotional state to better engage them during a lesson.
