For the first time, scientists have observed a swirling distortion...
Uranus and Neptune could be “rock giants,” not just ice worlds
For decades, scientists have believed that Uranus and Neptune are “ice giants,” planets made mostly of icy materials like water, ammonia and methane.
But a...
How Mars controls Earth’s climate
Earth's climate has swung between ice ages and warmer periods for millions of years, driven by subtle changes in our planet's orbit and axial...
