"The formation of the moon and the origin of Earth's water are two of the fundamental open questions in cosmo-chemistry," said the lead author of a new study.

Jupiter's atmosphere is characterized by several strong jet streams that flow west to east, carrying clouds of ammonia and other elements which create colored bands.

The video also shows stars, asteroids and even an arc of stray light from Mars.

"The investigation of other solar systems can help us understand how planets and even our own solar system formed."

The space rock hails from the explosive dawn of the solar system.

Some people think this celestial event can wreak havoc here on Earth, but NASA disagrees.

A hunk of ice and rock twice the size of Earth smashed into the planet four billion years ago, researchers think.

Scientists found that Mars's crust formed much earlier than previously thought.

The plan details five goals the agency and government hope to accomplish over the next 10 years.

Wind crashes into mountains and creates waves that tug on the planet's rotation.

Researchers think the infant planets are behind weird kinks and grooves in the star's gas-filled disk.

Around dusk tonight, Castor and Pollux will form a nearly straight line with Venus.

"We knew that every solar system body with an atmosphere and a solid rocky surface has dunes on it, but we didn't know what we'd find on Pluto."

Scientists discovered large quantities of the foul gas in the cloud tops of the planet

It absorbs some 99 percent of light hitting its surface.

A fundamental equation has cracked the evolution of how planets swarm around the sun.

We may finally have the tools we need to discover intelligent life on other planets—if only we'd stop making so much noise.

The treasure trove joins thousands of other exoplanets previously discovered.

Researchers recommend starting with Saturn and Jupiter.

See our own Milky Way galaxy before floating to a place where baby stars are formed.

An atmosphere is basically a giant blanket that can protect a planet from a star's barrage of dangerous radiation.

If you aren't willing to accept the evidence Earth is round, what do you do with Mars, Jupiter and the rest?

The gas giant is the biggest planet ever discovered when compared with its host star.

Volcanic action can both improve and reduce a planet's ability to host life.

The key is in how rings of dust around young stars behave.

The moon won't obscure three planets again in this way until 2036.

The best method for destroying a huge asteroid that is headed towards Earth that I've come across is to explode a thermonuclear warhead a few miles above the surface.

If humans land on Mars in 2025/2026, that qualifies as "full speed ahead" and means we got serious about this right now.

People are starting to disperse. I see confusion in every person. Everyone is questioning.

"No one from NASA ever came to me and said you can't do that. If anything they wanted to help me do it."
