  • Solar System’s Extraordinary Birth Environment

    One of the most extraordinary features of the solar system is that it contains adequate abundances of all the elements essential for advanced life. What makes it so exceptional is that the elements … more

  • Coreless Terrestrial Planets

    As I described in last week’s Today’s New Reasons To Believe, two MIT planetary scientists added to the list of these features. Their modeling of the formation history of planets the size … more

  • Dwarf Galaxies Test Big Bang

    The big bang creation event— as taught by the Bible for centuries1— now stands well established by astronomers’ observations of the universe.2 This observational evidence shows that … more

  • Violent Solar System Birth

    Imagine a luxurious house on a remote ranch. Looking out the windows you see majestic mountains on one side and a scenic ocean expanse out the other. The location insures that you can enjoy the … 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

  • Youngest Solar Systems Detected

    When I first started graduate school in 1991, only the planets in our solar system were known. By the time I finished almost six years later, astronomers had found over a dozen planets beyond the … more

  • Where Did Earth Get Its Phosphorus?

    Phosphates serve as the backbone for all nucleic acids and are the major repository of chemical energy for metabolism. The human body contains about 11,000 parts per million of phosphorus by weight. … more

  • Chronology of Early Solar System Events

    I enjoy traveling, whether taking a trip to visit relatives for Christmas or a summertime vacation to witness the beauty of creation. However, any trip with my family (wife and five kids) requires … 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
