The long search for Martian life

Life on Mars is the hot topic of the decade. The NASA missions Mars Science Laboratory in Gale Crater and Mars 2020 in Jezero Crater are searching for traces of martian life. The European/Russian rover mission ExoMars 2022 will be launched in September 2022 to search for life in Oxia Planum. In fact, we have been looking for life on Mars since the 1970s when the two Viking landers touched down on the surface of the planet in 1976.

How can you tell if that ET story is real?

We think we’re the first advanced earthlings—but how do we really know?

Imagine if, many millions of years ago, dinosaurs drove cars through cities of mile-high buildings. A preposterous idea, right? Over the course of tens of millions of years, however, all of the direct evidence of a civilization—its artifacts and remains—gets ground to dust. How do we really know, then, that there weren’t previous industrial civilizations on Earth that rose and fell long before human beings appeared? It’s a compelling thought experiment, and one that Adam Frank, a professor of physics and astronomy at the University of Rochester, and Gavin Schmidt, the director of the NASA Goddard Institute for Space Studies, take up in a paper published in the International Journal of Astrobiology.

The need of an ethics of planetary sustainability

How long will humankind survive? Besides the fact that we have been able to eliminate ourselves with nuclear weapons for decades, even without a third world war, the challenge to take care of the resources of our planet remains; we need to use them in a way that our children and their children can have a place on Earth as well. In this blog post Andreas Losch discusses his recent review article in the International Journal of Astrobiology, The need of an ethics of planetary sustainability

Aliens are more like us than we think

Hollywood films and Science-Fiction literature fuel the fantasy that aliens are other-worldly, monster-like beings, who are very different to humans. But, new research suggests that we have more in common with our extra-terrestrial neighbours, than initially thought. In a new study published in the International Journal of Astrobiology scientists from the University of Oxford show for the first time how evolutionary theory can be used to support alien predictions and better understand their behaviour.

The Implications of Cosmic Silence

In a paper published Aug. 3 in the International Journal of Astrobiology, Daniel Whitmire applying a statistical concept called the principle of mediocrity and argues that if we are typical, it follows that species such as ours go extinct soon after attaining technological knowledge.
