How can we peer back into the Big Bang? It may be as easy as turning on your television.
1 Percent of TV Static Comes from Light of the Big Bang
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.
Will the Universe Expand or Contract?
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.
Why Jupiter Has A Giant Red Spot
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.
13 Billion Years Ago, This Was Our Universe
It may take light as much as a million years to escape from the suns fiery interior; from there, it has to travel 93 million miles to Earth, traveling at 186,000 miles per second -- about 8 minutes.
Today's Sunlight Was Produced Before Human Civilization Began
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.
Is There Life on Saturn Moon Enceladus?
The core of Saturn is a scalding 21,000 degrees, twice the temperature of the sun's surface.
The Birth of Saturn

Lessons From NASA's Galileo Probe
To discover what created the Milky Way, scientists have to look back 13.6 billion years to the moments just after the Big Bang.
Did A Black Hole Create the Milky Way?
Do black holes create stars? Theres direct evidence that the ravenous appetite of a black hole sparks stars into life.
How the Milky Way Got Its Stars
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.
What Physics Doesn't Know About the Big Bang
NASAs Solar Dynamics Observatory listens to the sun by speeding up 40 days of recording into a few seconds
This Is What The Sun Sounds Like
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.
