Electrons released when cosmic rays strike water-ice can provide energy for microbes and facilitate the formation of complex organic molecules.

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 ...

Acclaimed astronomer Carl Sagan may have been more right than he knew when he famously quipped that “we are made of star stuff.” In a not-yet-peer-reviewed academic paper, Georgian Free University of ...

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 ...

When Earth formed 4.5 billion years ago, any phosphorus that was present likely sank into the molten core because of the element’s distinct chemical properties. However, phosphorus is essential for ...

Cosmic rays may already have erased some evidence of ancient life on Mars, at least in most of the places scientists are currently looking. But not all hope is lost. If chemical traces of ancient life ...

Astronomers have discovered a hitherto unknown source of the cosmic dust. As to why this dust is important to track? Well, these particles basically act as building blocks for stars. "The formation of ...

The traditional astrophysical recipe for life as we know it is quite simple: Get a rocky, gas-shrouded world in a “habitable zone” orbit around a star so that it’s not too hot or too cold. Then just ...

Adjust your perspective on lifeforms with the concept of cosmic whales. These enormous and mysterious beings redefine the ...
