Life on Mars sounds like something from a "Doctor Who" episode. But a study published in the International Journal of Astrobiology challenges the science fiction notion of that idea. The research ...

Window seats offer great views but expose passengers to higher UV-A radiation due to less atmospheric filtering and ineffective window blocking. While occasional travelers face minimal risk, frequent ...

Cosmic rays are high-energy particles that constantly bombard Earth from space and are influenced by the sun's magnetic activity. When the sun is active, fewer of these particles reach Earth; when the ...

Cosmic rays traveling through space may provide enough energy to sustain life even in incredibly cold and dark environments, a new study suggests. The staggeringly energetic neutrino likely came from ...

For a few hours each lunar day, the radiation environment near the moon quietly shifts. Measurements now suggest that parts of the moon's orbit pass through a region where harmful cosmic radiation ...

What processes other than water and energy could be responsible for creating life on other worlds? This is what a recent study published in the International Journal of Astrobiology hopes to address ...

The first step on the moon was one of humanity's most exciting accomplishments. Now scientists are planning return trips—and dreaming of Mars beyond. And finally, the trip to Mars is planned for the ...

As plans for missions to Mars accelerate, so do questions about how the human body might cope. A return trip to the red planet would give more than enough time for someone to become pregnant and even ...
