Planets

This celestial event only takes place around 13 times a century.

Mercury transits take place only around 13 times a century.

No, the first day of fall is technically not marked by the return of the pumpkin spice latte (although, unofficially, it kind of is).

The latest findings could help to explain some puzzling measurements collected by the Juno spacecraft, which is currently orbiting the planet.

The bright side is that you likely won't notice them in a really personal conflicting way like when Mercury is retrograde, according to astrologers.

When exactly plate tectonics emerged and how it has evolved through time are two of the most significant and hotly debated questions in Earth sciences today.

More than 4,000 planets beyond our solar system have been discovered since the first in 1992.

The planets are prompting some serious self-reflection and realizations this summer, according to astrologers.

Javi Poves challenged a Spanish science minister to a debate on the curvature of the Earth.

"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.
