Unexplained observations suggest the Moon is alive.

Was the moon a captured planet?

A collapsed star orbiting a pulsar has become a giant diamond.

Planet TrES-2b is so hot that its atmosphere absorbs virtually all the light from its star.

Charon is the strangest of Pluto’s very strange moons.

Flowing liquid nitrogen smoothed the vast plain known as Sputnik Planum.

If Planet 9 exists, it may have been stolen from another star system.

The mysterious planet may glow like a jellyfish.

Historic highlights from the record-setting Saturn probe.

Saturn's rings and moons teach us how planets formed around our sun -- and around other stars.

Greenhouse gasses from volcanoes have helped raise Venus' surface temperature to 900 degrees Fahrenheit.

Storm systems on Saturn form a perfect hexagon on the planet's north pole.

Was the moon a captured planet?

Unexplained observations suggest the Moon is alive.

Venus traps heat from the sun. Space probes discover volcanoes on this extremely hot planet.

Mars is about half the size of Earth, yet has volcanoes that are much larger than the ruptures on our planet. In this web exclusive, explore off-world volcanoes.

Professor Showman and Dr. Thaller compare Earth dust storms to Mars dust storms.

It may take light as much as a million years to escape from the sun’s fiery interior; from there, it has to travel 93 million miles to Earth, traveling at 186,000 miles per second -- about 8 minutes.

NASA's space probes find Triton covered in frozen nitrogen ice.

As scientists studied the Kuiper Belt, they became puzzled by a group of asteroids that deviated from the normal orbital path. The conclusion? There’s something massive out there that is pulling the asteroids out of line.

NASA’s Solar Dynamics Observatory listens to the sun by speeding up 40 days of recording into a few seconds

Nuclear fusion events create the elements in the universe with each reaction. The second heavy iron is created in a star’s core, it goes super nova and spreads the base elements into the universe.

Will gravity or expansion win? There are three endgames: the universe will continue expanding forever, gravity and expansion will find balance, or gravity wins and the universe begins to get smaller.

The Planck telescope peers through space and time towards the beginning of everything to capture an image of our universe from more than 13 billion years ago, 380,000 years after the Big Bang.

The heaviest metals in the universe can’t be created by nuclear fusion alone. Dense neutrino stars collide to create a burst of energy cataclysmic enough to bind the proton heavy stars into the heaviest elements like gold and lead.

Ever wonder how storms are formed on other planets? In this web exclusive, explore mega storms on other planets in our solar system.

Life is impossible on Venus, but can the brutal winds that sweep across the planet create the right conditions for life just above the surface?

Planet Nine sits on the dark, distant edge of our solar system. Until we see the planet with our own eyes, we won’t know much about it’s surface. One theory is that Planet 9 is rocky like Earth, but 10 times as massive.
