Particle Reservoir Blunts Solar Storm Damage

Our Sun looks remarkably stable, but as with all other stars, its magnetic field exhibits variability. This variability leads to events where the Sun’s magnetic field connects to Earth’s and causes an influx of charged particles. Recent observations show that Earth’s magnetic field houses a reservoir of charged particles that blunts the disruptive effects of such “reconnection” events. The implications of this research support the idea that Earth was specially designed in order to support advanced technological civilizations.


Imagine operating a telegraph in the middle of the night when, suddenly, you start receiving spark shocks from the machine. Though you disconnect the telegraph, it continues to function, driven by some unknown power source. Stepping outside, you see a brilliant aurora covering much of the sky with light strong enough to read by. Later reports reveal that the aurora was visible as far south as Hawaii.

177420840As incredible as this scenario sounds, such conditions arose during the 1859 Carrington Super Flare. These electromagnetic “storms” occur when the magnetic fields of the Sun and Earth interact. Fortunately, as recently reported in Science, Earth’s magnetic field features characteristics that serve to blunt the impact of these storms on advanced civilization.

Earth’s Natural Shield

Day after day, the Sun moves across the sky and provides a steady source of heat and light for a large fraction of life on Earth. But despite the Sun’s seeming constancy, scientists know that a number of violent solar events (flares, coronal mass ejections, and others) do impact Earth, as was the case in 1859 when the two bodies’ magnetic fields “reconnected” (see animation here).

During these reconnection events, large amounts of hot plasma from the solar wind gain a path directly toward Earth. The efficiency of the reconnection event plays a central role in determining the amount of energy transferred from the solar into Earth’s magnetosphere and ionosphere. However, recent observations revealed that the planet’s magnetic field houses a reservoir of charged particles that rush out toward the reconnection region in such a way that dampens the efficiency of reconnection.1 Consequently, each reconnection event causes much less damage to Earth’s surface than it would without the reservoir.

Assessing Other “Habitable” Planets

This research highlights yet another feature that any putative “habitable planet” must possess in order to be truly habitable—at least for human-like life and advanced civilization. Specifically, the planet must generate a substantial magnetic field otherwise it cannot host the reservoir of charged particles to dampen reconnection events.

Scientists have expressed much interested in M-dwarf stars because they represent about 75 percent of all stars in the Milky Way Galaxy. Moreover, research indicates that many, if not all, M-dwarf stars host planets. The dimmer nature of these stars means the region where a planet could host liquid water resides much closer to the star, which results in tidal locking such that the planet has no magnetic field.

The number of known planets, as well as the number of environments where those planets reside, continues to grow. At the same time, the list of conditions required for advanced life (based, at least, on what we know from Earth) grows more stringent. Such a finding comports well with the idea of a God who fashioned Earth for human life and then commanded humanity to study creation in order to manage it well.

  • Hidden Treasures in the Book of Job

    Arguably the oldest book in the Bible, the book of Job has a surprising amount to say about some of the newest scientific discoveries and controversies. With careful consideration and exegesis, Hugh Ross shows that the Bible is an accurate predictor of scientific discoveries, and that both the book of Scripture and the book of nature are consistent both internally and externally.
  • Creating Life in the Lab

    Representing the best of RTB's efforts to anticipate scientific breakthroughs and explain their contribution to the case for Christian faith, biochemist Fuz Rana shows how recent advances in synthetic biology actually undermine the evolutionary explanation for the origin of life. Creating Life in the Lab addresses the scientific, theological, and philosophical aspects on both the dangers and promises of synthetic biology.
  • If God Made the Universe…Why Is It the Way It Is?

    Drawing from his popular book Why the Universe Is the Way It Is, Dr. Hugh Ross shares Scripture, stunning satellite photos, and the most recent scientific findings to explain the great love story that is our universe. This DVD series invites you to be a part of Dr. Ross’ small group. Each session includes a brief presentation (about 20 minutes), followed by Q&A.
  • Impact Events: The Earth

    In this unique student devotional, astrophysicist Jeff Zweerink and seasoned small-group leader Ken Hultgren connect little-known facts about our planet with faith-building insights about the Creator. The booklet includes practical, yet thought-provoking questions to help students apply each lesson’s principles to their lives. This Impact Events series is designed to transform your life and faith with truth from God’s Word and evidence from God’s world. God wants to impact your life. Will you let Him?
