Meteor impacts are an inevitable part of being a rocky planet in space. The craters they leave behind are a window into the tumultuous history of Earth.
Rubble pile asteroids are like giant space cushions, floating around the Solar System for billions of years. Here’s what that means for planetary defence.
Starting at the surface, you would have to dig nearly 2,000 miles before reaching the Earth’s core. No one could survive that trip – and the 10,000-degree F heat once there would vaporize you anyway.
Blue Marble is the last photograph of the whole Earth taken by an actual human using analogue film: developed in a darkroom when the crew returned to Earth.
Scientists have uncovered the long-term history of our receding moon. And it’s not from studying the moon itself, but from reading signals in ancient layers of rock on Earth.
When the Orion Crew Capsule orbits the Moon there will be no one on board. But the mission will mark a key step in bringing humans back to Earth’s dusty sidekick.
NASA, NOAA and SpaceWeather say a coronal mass ejection will reach Earth this week. It has the potential to knock out communications in some parts of the world.
By tracking a meteorite found in Morocco back to its origin in an asteroid crater on Mars millions of years ago, scientists can learn more about how the planets formed.
The Moon illusion is what makes the Moon look giant when you see it rising over a distant horizon. An astronomer explains what causes this awe-inspiring trick of the mind.
Current trends suggest that powerful nations are defining the rules of resource use in space and satellite access in ways that will make it hard for developing nations to ever catch up.
