"It seems that an important part of the Milky Way's stellar mass was formed due to the interactions with Sagittarius and wouldn't exist otherwise," scientist Carme Gallart said.

Researchers identified the minor planets beyond the orbit of Neptune.

Data indicates that the object could measure anywhere between 1.1 and just over 2.6 miles in diameter, based on its observed magnitude.

The planet is located around 1,000 light-years from Earth and experiences average temperatures of more than 1,800 degrees Fahrenheit.

The tropical year—or the length of time it takes for the Earth to go from one equinox to the next—is 365 days, 5 hours, 48 minutes and 45 seconds long.

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.
