Physicists from Trinity College Dublin have developed a space weather warning system to help safeguard electricity and communications systems from solar and geomagnetic storms.

The surface of the Earth preserves little or no information about its distant past. Constant tectonic activity has recycled Earth's crust and shifted landmasses. Rainfall, wind, ice and snow have weathered away surface f...

Does Pluto really have baby snowflakes and ice volcanoes? New Horizons team members weigh in.

For Jupiterians (Jovians?) a trip around the Sun takes 12 Earth years. If you were born today on the planet or one of its moons, you’d turn one year old in 2027 and reach the ripe old age of 12 in 2111. In this remarka...
