  • TNRTB Classic: Refocusing on the Moon

    Monday’s TNRTB discussed the fine-tuned features of Earth’s celestial companion: the Moon. Previous NASA missions and scientific research revealed the Moon’s essential role in the … more

  • Our Remarkable Moon

    We had a rare opportunity to witness a solar eclipse on Sunday, May 20. Of course, looking directly into the Sun is never a good idea. So, using my telescope’s finder scope, Kathy and I … more

  • TNRTB Classic: The Benefits of Bombardments

    Collisions with large objects from within the solar system have occurred throughout Earth’s history. These impacts result directly from the processes that formed the Sun and planets. Many large … more

  • Late Heavy Bombardment Slows to a Trickle

    Recent research indicates that, although the rate of the sterilizing events dropped significantly, they continued at a slow pace until 550 million years ago. This research provides a partial answer to … more

  • TNRTB Classic: Exoplanet Studies

    Despite the probable existence of billions of planets in the Milky Way Galaxy, evidence continues to demonstrate that Earth may be alone in manifesting all the attributes for sustaining advanced life. … more

  • Chaos versus Order in Planetary Systems

    For the first time, new computer simulation studies reveal what makes our solar system so special and why, despite the probable existence of billions of planets in the Milky Way Galaxy, Earth may be … more

  • Scientific Fusion

    My husband and I love watching Iron Chef America, the Food Network show where top-notch chefs go toe-to-toe in an hour-long culinary battle. It’s particularly fascinating to watch the … more

  • Sunspot Cycle and Human Health

    For thousands of years, medical practitioners have speculated that human maladies might be correlated with environmental cycles. For example, certain times of the night and certain phases of the moon … more

  • Resolving Faint Sun Paradoxes, Part 3

    In part 1 of this series, I defined the faint young Sun paradox and described how, in the 1970s and 1980s, astronomers and physicists concluded that volcanic gas emissions pumped enough extra carbon … more

  • Resolving Faint Sun Paradoxes, Part 2

    First articulated in the early 1970s, the faint Sun paradox (also known as the faint young Sun paradox) reveals that the Sun today is about 30 percent brighter than it was when life originated on … more

  • Resolving Faint Sun Paradoxes, Part 1

    In science, resolving a paradox almost always results in a much deeper understanding of the record of nature and often produces additional evidence for supernatural design. New and developing … more
