  • Survival of Earth-life on Mars

    NASA expends considerable effort to ensure any life-detecting spacecraft they send to Mars do not, themselves, contaminate Mars with Earth-life. At every phase of the mission multiple steps are taken … more

  • An Ocean of Wonder

    The recent discovery and analysis of a planet described as “something like our own Earth” highlights the point. This particular planet, with the colorful name GJ1214, is about six and half … more

  • Is Oxygen a Signature for Life?

    Astrobiology was launched as a scientific discipline at the beginning of the twenty-first century. Its stated goal is to find extraterrestrial life. But there's a problem. How does one go about … more

  • The Oxygen–Antioxidant Paradox

    Advanced life requires the efficient processing of energy to perform work. Only the oxidation of carbohydrates, starches, and fats can deliver the necessary efficiency. However, the presence of oxygen … more

  • Rare Solar System Location

    The solar system’s current position (in between two nearby exceptionally symmetrical and widely separated spiral arms that are devoid of any significant spurs or feathers) keeps the solar … more

  • Design of the Solar System’s Gas Giants

    The masses and orbits of the solar system’s four gas giant planets are crucial for life on planet Earth. Without the gas giant planets, Earth would suffer from frequent life-destructive … more

  • Martian Climate Instabilities Compared to Earth’s

    Mars is a good example of such a pathway. It also is a good example of how the study of other planets can expose hidden evidences for supernatural design in our own planet.
