This video explores the key characteristics of each planet within our solar system. Suitable for teaching science at KS1 and ...

Contrary to what some people think, the Earth isn’t the center of the Universe. But what if it was? What if those medieval ...

Trying to understand the Universe is often less about seeing it clearly and more about accepting how quickly our intuition breaks down. If Earth were reduced to the size of a small 12 centimeter ...

Dead Planets Society is a podcast that takes outlandish ideas about how to tinker with the cosmos – from snapping the moon in half to causing a gravitational wave apocalypse – and subjects them to the ...

Are we alone in the universe? For scientists working on NASA's proposed Habitable Worlds Observatory, that question is no ...

Add Yahoo as a preferred source to see more of our stories on Google. Are planets in the solar system that are closer to the Sun older than the ones further away? – Gavriel, age 10, Paducah, Kentucky ...

Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a ...

Conditions in the early universe might have enabled rocky planets with water to form much earlier than anticipated, potentially allowing life to begin sooner too. Astrophysicists studying the early ...

A newly discovered object in a distant solar system doesn't fit neatly into the current definitions of moon or planet.

A Jupiter-size exoplanet orbiting a dead star baffled astronomers. But the planet named WD 1856 b could preview the fate of our own solar system when the sun dies.

A pair of giant planets circling a star more than 1,100 light-years from Earth looks almost too bloated to be real. Each world is about the size of Jupiter. Yet both are far lighter than expected, ...

Based on new simulations, scientists believe that giant gas planets across the universe can often collide and merge into even bigger gas plants — behemoths called "super-Jupiters." In the cosmic ...
