Life on Other Planets

  • 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

  • Too Much Sulfur

    Sulfur plays a crucial role in life chemistry. This fact became personal for me a year ago when I was diagnosed as sulfur deficient. Many protein functions crucially depend on sulfur. Fortunately, … more

  • Why Jupiter and Saturn Have No Twins

    Likewise, the discovery of over 300 extrasolar gas giant planets combined with spacecraft missions to explore the outer solar system is beginning to establish the rare gas giant planet system … more

  • Photosynthesis Is Not Enough

    This event occurred approximately 2.4 billion years ago. The oxygen content of Earth’s atmosphere rose from just one thousandth of a percent (10-5) of its present level (about 21 percent of the … more

  • Milky Way Galaxy’s Tiny Black Hole

    The latest and most definitive measurement puts the mass of that black hole at 3,600,000 times the mass of the Sun.1

    The Milky Way Galaxy’s central black hole by itself is not dangerous to … more

  • Galactic Habitable Zones

    In April 2008, the fifth Astrobiology Science Conference convened in Santa Clara, California. According to its mission statement, the SETI Institute, which hosts these conferences, seeks to … 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.

    In a recent issue of … more

  • Water on Mars Too Salty for Life

    The intense salty taste followed by spewed water in the sink is a telltale sign that the system isn’t properly washing the column with the liquid from the brine tank.

    Salty water is not good to … more

  • Digging on Mars with Phoenix

    This NASA mission left Earth about 9 months ago and successfully landed a spacecraft near Mars’ north polar cap on June 25, 2008. Using a scoop on the end of a 7-foot arm, Phoenix has and will … more

  • No, No, Nanobacteria

    Size also matters to biochemists. Conventional wisdom places the lower bound on life at about 1 micron (give or take a few hundred nanometers). In 1999, the National Academy of Sciences sponsored a … more

  • Rare Earth Confirmed

    A couple of months ago I discussed an upgrade to the Arecibo Radio Telescope that would make it more effective for searching for intelligent life in outer space (SETI). That article included … more

  • Life on Titan?

    Members of the Cassini-Huygens mission to Saturn’s moons have published the first of their findings from the second close flyby by the planetary probe of Saturn’s largest moon, Titan. They … more

  • Doubts About Some Water on Mars

    In the December 8, 2006 issue of Science, a report was published suggesting that water had flowed on the surface of Mars in recent decades. A reexamination of the data led to the publishing of a new … more

  • Too Salty for Life

    Consequently, the search for life outside of Earth has embraced the mantra, “follow the water”. But, as noted in a recent summary posted here, much of the evidence for water on Mars can … more

  • Anybody Out There?

    At the age of seven, I heard about the crash of a flying saucer recovered on a ranch near Roswell, New Mexico. While my dad thought the whole thing was a bunch of foolishness, my friends and I had … more
