How can we peer back into the Big Bang? It may be as easy as turning on your television.

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.

Jupiter's weather doesn't come from the sun; it comes from deep within the planet itself. Jupiter also spins faster than any other planet in our solar system.

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.

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.

In November 2012, astronomers spotted a new planet 100 light years from Earth. There may be as many as 200 billion rogue planets in our galaxy - and one could be headed our way.

In 2005, NASA's Cassini spacecraft captured an astounding sight: geysers of icy water spewing from Enceladus, one of Saturn's moons.

The core of Saturn is a scalding 21,000 degrees, twice the temperature of the sun's surface.

On December 7, 1995, NASA's Galileo spacecraft dropped a probe into Jupiter's atmosphere.

To discover what created the Milky Way, scientists have to look back 13.6 billion years to the moments just after the Big Bang.

Do black holes create stars? There’s direct evidence that the ravenous appetite of a black hole sparks stars into life.

Earth's orbit around the sun is unstable and the farther Earth is from the sun, the more it cools. Are we headed for a global catastrophe?

Everything we know and see started with the Big Bang but physics has yet to figure out exactly how it happened.

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

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.

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

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.

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.

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.

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.

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?

New evidence suggests that there’s a ninth planet in our solar system. Sorry, Pluto, we’re not talking about you. The only thing is... we’ve yet to actually see this planet.

On December 7, 1995, NASA's Galileo spacecraft dropped a probe into Jupiter's atmosphere.

How can we peer back into the Big Bang? It may be as easy as turning on your television.

As infant planets, Earth and Venus were twins but today they couldn’t be more different. Two events caused a radical divergence in their development.

Jupiter's weather doesn't come from the sun; it comes from deep within the planet itself. Jupiter also spins faster than any other planet in our solar system.

Venus had water once, but it became desiccated with no protection from the sun. It’s a glimpse of Earth’s future as the sun keeps getting larger, eventually causing a cataclysmic greenhouse event.

Everything we know and see started with the Big Bang but physics has yet to figure out exactly how it happened.

There’s a level of danger out in space that’s beyond even our own imaginations. We asked our How the Universe Works experts to describe the most mind boggling way the universe could kill us.

The oort cloud comets are dinosaur bones of solar system formation. Contained in them are the ingredients that made up our planets.

In 2005, NASA's Cassini spacecraft captured an astounding sight: geysers of icy water spewing from Enceladus, one of Saturn's moons.

The core of Saturn is a scalding 21,000 degrees, twice the temperature of the sun's surface.
