Possible Astronomical Catastrophes

Possible Astronomical Catastrophes

The media often fills a void in natural disasters on Earth by headlining possible astronomical catastrophes. A recent example was a headline in USA Today stating that a “Rare but extreme solar event could disrupt life on earth.”

The article tells us that a solar superflare would fry communications satellites and produce electric currents strong enough to paralyze the power grid. The article tells us that in 1859, a violent solar storm knocked out the telegraph network in large parts of northern Europe and North America. It said if a solar superflare happened today, it would knock out phone services, GPS, credit card authorization, and weather and climate monitoring. The USA Today report is taken from the peer-reviewed journal Science, a publication of the American Association for the Advancement of Science.

So, what is the danger of a solar superflare to you and me? The answer to that question is “virtually none.” The point is that solar superflares occur in stars like our Sun roughly once every 10,000 years. The flare in 1859 was not a solar superflare but merely a flare for which the nascent electric industry was unprepared. Today, such a flare would not significantly affect today’s telegraph or phone service.

The lack of possible astronomical catastrophes shows the intelligence and design built into our planet and solar system. A G-2-type star, like our Sun, has infrequent occurrences of solar superflare. Other spectral classes of stars can have solar superflares every 1000 years. That means the occurrence of life on a planet around another star is highly unlikely, if not impossible.

In his 1956 CBS television program “Our Mister Sun,” the late Dr. Frank Baxter said, “The more we know of the creation, the closer we get to the Creator.” The lack of solar superflares is another example of the truth of his statement.

Solar Wind and Earth’s Magnetic Shield

Solar Wind and Earth’s Magnetic Shield

For a hundred years, scientists looked for the answer to a perplexing question. In 1859 British astronomers observed what we now call a solar flare. The next day there was a disturbance of Earth’s magnetic field called a geomagnetic storm. Scientists were puzzled over what was happening. After a century of study, the answer came down to solar wind and Earth’s magnetic shield.

In 1958, American astrophysicist Eugene Parker described the phenomenon and named it “solar wind.” The solar wind consists of charged particles ejected from the corona (extended outer layer) of the Sun and traveling at high speed into space. This material is plasma, a mixture of negative electrons and positive ions. Since electric charges and magnetic fields interact, the planet’s magnetic field steers the solar wind away from the planet’s surface when it reaches Earth. Because Earth’s magnetic field originates from the North and South poles, we see the interaction in those regions as beautiful auroras, the Northern and Southern lights.

What if Earth did not have a magnetic field? The solar wind would reach Earth’s surface and significantly damage living cells, bringing an end to life. Our neighboring planets Venus, Mars, and Mercury have little or no magnetic field and therefore are bombarded by the solar wind.

Why is our planet different? Why do we have the protection of a magnetic field? The motion of the molten iron in Earth’s core produces the magnetic field. Why does Earth have a molten iron core? Heat generated by the decay of the radioactive elements uranium and thorium keeps the iron core from becoming solid.

The bottom line is this: Hidden inside our planet is a magnetic-field generator powered by unseen radioactivity that gives us an invisible magnetic shield protecting us from invisible destructive particles coming from the Sun. This same process also gives us beautiful auroras we enjoy watching. The solar wind and Earth’s magnetic shield give us one more example of the beautiful design of the planet we call home. Did this all happen by accident? We don’t think so.
