Exoplanet discoveries over recent years have shown that terrestrial planets are exceptionally common. Many of these planets are in compact systems that result in complex orbital dynamics….
Saturn’s moon Enceladus has vents emerging from a sub-surface ocean, offering unique probes into the liquid environment. These vents drain into the larger neutral torus in orbit around Saturn….
The search for biology on neighbor planet Mars won’t play out like a Hollywood movie starring little green men. Rather, many scientists agree if there was life on the Red Planet, it probably will present itself as fossilized bacteria….
Description: Solar system exploration is in an extraordinary state of expansion. Scientific capabilities to search for evidence of extant or relic life outside Earth–among the principal goals of solar system exploration–are advancing rapidly….
Researchers have performed numerical simulations and compared the results to the composition of the ancient Martian atmosphere trapped in an old meteorite. The researchers have concluded that, 4 billion years ago, Mars had a dense atmosphere whose surface pressure was…
The detection of Earth-like exoplanets in the habitable zone of their stars, and their spectroscopic characterization in a search for biosignatures, requires starlight suppression that exceeds the current best ground-based performance by orders of magnitude….
Astrobiology is a scientific discipline that studies life in the Universe. We call it a discipline and not a science because some authors have cast doubts over its epistemological status by calling it ‘a science without an object of study’….
River deposits exist across the surface of Mars and record a surface environment from over 3.5 billion years ago that was able to support liquid water at the surface….
Researchers at the University of York have shown that molecules brought to earth in meteorite strikes could potentially be converted into the building blocks of DNA….
Scientists have discovered traces of life more than half-a-billion years old that could change the way we think about how all animals evolved on earth….
