How hard is it for evolution to produce intelligent life like humans? We don't really know, but some computational modelers tried to answer the question.
Biological processes might have led to greater continental crust coverage than would be expected on a planet without life.
Astrobiologists have discovered a possible new pathway for the prebiotic self-assembly of biologically important molecules by replicating extreme conditions caused by asteroid impacts.
How do we find the effects of extreme #space radiation on human health? Answer lies with yeast in your bread! @NASA scientists are launching #BioSentinel later this year. #Astrobiology By @strayologist
Were metabolic pathways established before life emerged? New experiments observe life-like patterns self-propagating on #mineral surfaces. #astrobiology #geobiology
For the past few decades, scientists have been looking at planets outside of our solar system to see if they could host life. Now, scientists have discovered another factor for habitability: radiation from the planet’s central star.
How and why humans exist are questions that have challenged different cultures ever since the dawn of civilization. Many scientists have taken upon their shoulders the duty of answering these fundamental questions, coming up with several especially creative ideas over the past few decades. One prominent idea is that…
Scientists use computer models to simulate what oxygen would look like on far away planets and found a chemical signature that helps us tell the difference between oxygen from life and oxygen from other sources.
Early Martian life may have used sulfur as an energy source Using an environment on Earth that simulates early Mars conditions, researchers found an abundance of bacteria that get their energy from sulfur-containing molecules, suggesting a new focus in the search for biosignatures on the Red Planet.

Since we are currently unable to visit some of the distant places in our solar system, we send probes to visit them for us. Only four spacecraft have visited Saturn, and for roughly 20 years some of the best data we had were images taken during the flybys of Pioneer 11, Voyager 1, and Voyager 2. That changed with the…
