Life on our planet appeared early in Earth's history. Surprisingly early, since in its early youth our planet didn't have much of the chemical ingredients necessary for life to evolve. Since prebiotic ...

A Sydney Ph.D. student has recreated a tiny piece of the universe inside a bottle in her laboratory, producing cosmic dust from scratch. The results shed new light on how the chemical building blocks ...

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 ...

Researchers believe it is likely that elements needed for life mostly arrived on Earth in the form of cosmic dust. Before life existed on Earth, there had to be chemistry to form organic molecules ...

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 ...

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 ...
