Interesting Sun Facts

Interesting Sun FactsWe all know some things about the Sun. We know it is powered by thermonuclear fusion, that it is a G-2 type spectral star, and that it is the primary energy source for the Earth. Many of us have seen a solar eclipse when the Moon blocks out the photosphere of the Sun and lets us see its corona. We know that the Sun is not just a ball of fire but a complex globe. Here are some more interesting Sun facts that are relatively new to us:

The light that we see coming from the Sun is from its photosphere. The photosphere is a thin incandescent layer that is just 200 miles (322 km) thick. That is less than one four-thousandth of the Sun’s diameter and is like the outer skin of an onion, only thinner than that.

The energy of the Sun is created in its core, which is a very small sphere, just one two-hundredth of the Sun’s volume. Every second that small ball emits the energy of 96 billion 1-megaton hydrogen bombs. The Sun’s weight decreases by 4 million tons every second as mass is turned into energy and radiated from the photosphere.

The Sun spins on its axis once a month, just as the Moon does. The center 70% of the Sun spins uniformly like a solid ball. The remaining 30% has different spins with the poles turning more slowly than the equator. These zones spinning at different speeds meet in a recently discovered zone 130,000 miles (209,000 km) below the surface. That zone is called the tachocline, and it’s where the Sun’s magnetic field originates.

Sunspots are areas where the local magnetic field is 5,000 times stronger than on the rest of the surface. The stronger magnetic field constricts the Sun’s plasma. When sunspots are rare, it seems that Earth’s climate becomes colder. Starting in 1645 there were few sunspots for 70 years. During that time, Earth became colder, people abandoned fishing colonies in Iceland and Greenland, and the Thames River and Venice canals went through periods of freezing solid.

As scientists probe more in-depth, they learn many interesting Sun facts. Just as in many other areas, the more we learn, the more questions we have. What effect do sunspots have on life on Earth? How can they affect our climate? What will happen in the next sunspot cycle? Tomorrow, we will look more into questions about sunspots. As we learn more interesting Sun facts, we realize the amazing design wisdom of the Creator to make life on this planet possible.

Jupiter Is in Opposition

Jupiter Is in OppositionJune 10, 2019, is an excellent time to observe the largest planet in our solar system. The reason is that Jupiter is in opposition to our Sun.

When astronomers say that Jupiter is in opposition, they mean that planet Earth is passing between the Sun and Jupiter. At this time, Jupiter will rise in the east as the Sun sets in the west, and it will set in the west as the Sun rises in the east. In other words, Jupiter will be visible all night long, and it will be at its highest point in the sky in the middle of the night.

The picture was taken by the JunoCam on NASA’s spacecraft Juno which is currently orbiting Jupiter. NASA posts the raw images online and encourages individuals to download and process them. Citizen scientist Kevin M. Gill enhanced this one. You can find access to the raw images and see the work of other citizen scientists by clicking HERE.

When you see Jupiter in the sky tonight, it will not look like this picture, but it will be the brightest object in the sky. Jupiter is not a rocky planet like Earth. It’s a gas giant which if were 80 times more massive, would be hot enough to set off nuclear reactions in its core. Then it would be a star giving off its own light instead of just reflecting the Sun’s light. However, if you could lump all the other planets in our solar system together (including Earth), Jupiter would be 2.5 times more massive than them all.

Why do we need such a huge gas giant in the outer solar system? As we have said in previous posts, Jupiter is a comet sweeper. With its massive size and gravity, Jupiter protects us from objects such as comets coming from outside our solar system. In the 1990s, NASA observed Jupiter pulling apart and destroying comet Shoemaker-Levy 9. You can read about that in our previous post HERE. Jupiter also affects Earth’s climate cycles, which you can read about HERE.

Jupiter is in opposition about every 13 months. Last year opposition occurred in May. Next year it will be on July 14. If you miss seeing Jupiter tonight because of cloudy weather or any other reason, don’t despair. Jupiter will be closest to Earth on June 12, and it will continue to be visible, but right now it’s visible all night long.

While Jupiter is in opposition, or at any other time, look up and thank God that He has created such a marvelous and unique solar system to make life possible.

Synergy – Working Together

Synergy – Working TogetherThe word “synergy” comes from a Greek word meaning “working together.” We have often mentioned “symbiotic” relationships where living things work together in various ways. When non-biological forces work together with living things, we can call it synergy.

Synergy describes the relationship between plate tectonics and life on Earth working together. Plate tectonics involves plates of Earth’s crust moving in relation to each other. Plate tectonics is the force responsible for making continents and mountains and for causing volcanoes and earthquakes. Without photosynthetic life (plants), plate tectonics would have shut down because photosynthetic organisms provide energy for Earth’s geochemical cycles. Without plate tectonics, Earth’s crust would be a solid lid sealing vital nutrients and elements beneath the surface. The nutrients needed by plants would not be available. That means there would be no photosynthetic life.

Animals and humans depend on plants for food. The animals that don’t eat plants feed on the animals that do. It’s photosynthesis that removes the carbon dioxide from the atmosphere and releases oxygen. All animals need oxygen, and excess carbon dioxide would result in a greenhouse effect, heating the Earth and making life impossible.

The point is that plate tectonics requires photosynthetic life, and life requires plate tectonics. Therefore all forms of life on Earth require both photosynthesis and plate tectonics working together in the right balance to exist. Was this balanced synergy system merely accidental, or was it planned? We think it shows intelligent planning by a divine Engineer.

For a fuller explanation of this, we recommend Dr. Hugh Ross’s book Improbable Planet: How Earth Became Humanity’s Home.

How The Sun Works

How The Sun WorksWe depend on the Sun every day to generate the energy that makes life on Earth possible, but have you considered how the Sun works?

The key to the Sun’s energy-supplying ability is a delicate balance between gravity and electromagnetism. Gravity curves space and pulls together all objects that have mass. The greater the mass, the greater the force of gravity. Right now gravity is pulling us toward the center of the Earth, but we are being held in place by the strength of the Earth’s crust and whatever floors or objects we have below us. The strength of the surfaces supporting us comes from electromagnetic forces between electrons and the protons in the nucleus of atoms. Those forces bond atoms of elements to each other forming compounds.

Since the Sun’s mass is more than a million times that of Earth, its gravity is more than a million times as great. The tremendous force in the core of the Sun overcomes the electromagnetic force and squeezes atoms of hydrogen tightly together igniting a thermonuclear reaction producing helium.

The creation of helium atoms releases high energy gamma-ray photons. If those gamma rays reached Earth, they would kill us. But the vast majority of them are transformed before they leave the surface of the Sun. On the way from the core to the surface they bounce off protons and electrons heating the hydrogen gas in the outer portion of the Sun. That heating increases the gas pressure enough to overcome the pull of gravity. Otherwise, the Sun would collapse on itself.

The bouncing of those gamma rays slows them so much that it takes hundreds of thousands of years for them to reach the Sun’s surface. If they could travel in a straight line, it would take only seconds, but they would emerge as deadly gamma rays that would reach the Earth in eight minutes, destroying all life. By the time those sterilizing gamma-ray photons reach the Sun’s surface, their energy has mainly been reduced to life-giving optical photons. There are still some dangerous rays that reach the Earth, but our atmosphere takes care of most of those.

That is a very simplified description of how the Sun works. Our Sun is a special star that provides the energy needed to sustain life on Earth without the high-energy rays that would destroy it. As you enjoy a beautiful sunset, you don’t have to know how the Sun works, but the Creator did. This finely-tuned system shows evidence of design by a Master Engineer, not a chance accident.

California Poppies Thrive

California Poppies ThriveThe past twelve months have been a time that most native Californians will never forget. After several years of drought, the entire state was affected by massive forest fires. When the fires were finally out, it seemed that everything would get back to normal, but then the rains started. Between the heavy snow and the unusually heavy rains, massive flooding became an issue. Without vegetation to stop the runoff, gloom and doom predictors were having a field day. The future looked bad, especially for southern California, but then came the California poppies.

I recently got a letter from a friend of mine who lives in southern California. The letter included pictures of what a few months ago was ugly, dark-colored, barren rock. The new images were ablaze with color. The California poppies withstood the fire because their seeds are not combustible and germinate faster in the conditions the fires produced. The seeds are also shaped in such a way that they don’t wash out even in heavy rain. With no competition, no predation to destroy the young plants, the poppies grew and bloomed like crazy.

Norma Privitt writing in the July/August/September 2019 issue of Power for Today described it this way:

“What a year this has been for California poppies! Abundant rain has unleashed God’s glorious array of orange flowers over all the barren hills. Even the limitations of TV do not restrict the obvious explosion of color. We traveled to view the poppies in previous years when their glory was only a smidgen of this year’s, but so many have made this year’s pilgrimage their cars line both sides of the roads, and finally, shuttle buses have had to be arranged. It almost seems symbolic that the plant that will anchor the soil and allow the land to begin to recover is a plant that blooms with brilliant orange drawing attention to God’s provision, even when human greed and abuse cause pain.”

Through California poppies, God has provided a way to bring beauty and hope even when things look dark and bleak.

Beautiful Tulips in History and Culture

Beautiful Tulips in History and CultureTheir vibrantly colored blossoms are symbolic of spring. Tulips are part of the lily family (Liliaceae) and exist in many different species. They flower in the spring and die back in summer when the life is stored in an underground bulb until the next spring. Beautiful tulips are an excellent example of the beauty designed into this planet.

Tulips are known for their bold colors and attractive shape. Most varieties are almost perfectly symmetrical. The blooms have three petals and three sepals, but the tulip appears to have six petals because the sepals are large and generally the same color as the petals. You can find tulips in almost any color from white to black, but the bright and sunny colors are the most popular.

Without a doubt, beautiful tulips have a rich and interesting history. They originally grew wild in temperate areas from southern Europe to central Asia. They were first cultivated in Asia around the tenth century. Diplomats who visited the Ottoman Empire in the sixteenth century brought them back to Europe where they became hugely popular.

The tulip obsession began with Flemish botanist Carolus Clusius in 1594. He was the first person to identify “broken tulips,” which is a virus infection that causes impressive streaks in the petals. He would go on to create many different color variations of the flower. His amazing tulips led to a period from 1634 to 1637 called “tulip mania” when enthusiasm for the flower created an economic frenzy. Tulips quickly became the most expensive flowers in the world. At the peak of tulip mania, some bulbs were selling for ten times more than the annual income of a skilled worker. People even used tulip bulbs as currency. Artists of the Dutch Golden Age, including Rembrandt, depicted tulips in their paintings.

Today, the tulip is the national flower of Turkey and Afghanistan, but the most prolific producer of tulips is the Netherlands. There are annual tulip festivals around the world including the Netherlands, England, Switzerland, Canada, and even Australia, where the spring bloom occurs in September and October. Several locations in the United States have tulip festivals, including Holland, Michigan, which is near where we live.

It’s interesting how tulips could have such an impact on economics, culture, and history. God gave us beautiful tulips, and human intelligence has modified them to develop a variety of colors and patterns. If human intelligence could do that, think how much more intelligence was required to create the living plant with the genetic code that made it all possible.

How Far Away Is the Sun?

How Far Away Is the Sun?Does it matter how far away the Sun is? Absolutely yes. The picture shows the order of the planets in our solar system, but not their distance from the Sun. So how far away is the Sun from Earth?

Any star that has planets orbiting it may potentially create a “habitable zone” where the light and heat are just right for the possibility of life to exist. Earth resides in the middle of the Sun’s habitable zone with Venus and Mars near the edge of the zone. Of course, there are many other factors required to support any kind of life, and it appears that Earth is the only planet in our solar system that has all of those factors. Earth has everything needed to support not just primitive life, but advanced life.

So what is the range of the habitable zone? That depends on the star. The size and brightness of the star are critical. Another essential factor is the type of radiation emitted by the star. Our Sun has the just-right radiation. Other stars may emit x-rays, gamma rays, or other deadly radiation in amounts that would destroy all life and prevent a habitable zone from existing.

Back in the eighteenth century, scientists determined the distance to the Sun by watching a transit of Venus across the Sun. Venus passes between the Earth and the Sun twice every hundred years or so. By measuring the time of the transit of Venus from two locations on Earth, scientists were able to use triangulation and simple math to calculate the distance to the Sun.

But the question was, how far away is the Sun? The Sun is about 93,000,000 miles (150,000,000 km) away from us. Since the speed of light is 186,000 miles (300,000 km) per second, it takes about eight and one-third minutes for the light from the Sun to reach the surface of the Earth. The energy the Sun delivers to our planet is just right to make life possible.

If someone asks you “how far away is the Sun,” you can say it is the “just right” distance. There are so many “just right” features of our planet that we can genuinely say we are in the “Goldilocks Zone.” Some think it was all just an accident, but we believe it was God’s plan and design.

Science and Technology vs. Greed and Stupidity

Science and Technology vs. Greed and StupidityIf you believe everything you read about science and technology in magazines and newspapers, you might want to question how much of it is factual. The way the media presents the stories, you might get the idea that science and technology are making such rapid advancements that in a few decades, we will solve all of the problems of humanity. There is no question that incredible advances have been made in medicine and agriculture. However, what many people don’t realize is that while some critical areas are advancing, others seem to be losing ground.

The Centers for Disease Control and Prevention tells us: “An American mom today is 50% more likely to die in childbirth than her own mother was.” The primary cause seems to be that health professionals have biases causing them to overlook symptoms. Food shortages are also creating an increase in disease and death due to malnutrition. The primary cause is that there has been a 20% drop in the abundance of food production in countries that depend on their domestic food supply. Humans have reduced the population of pollinators, including wild bees, endangering crop production. Over-fishing is beginning to threaten the primary source of protein for billions of people. The human destruction of mangrove forests and coastal coral reefs has placed 300 million people at increased risk of flooding.

God has given us not only the resources to feed every human on the planet today, but also the way to live with each other to allow the maximum potential for the food and medicine to reach the people who need it. The Genesis account tells us that God gave Adam everything he needed and that by the sweat of his brow, he would be able to eat. Humans have allowed power and control to rule what we do. We have made money and possessions the focus of our activity instead of focusing on God and serving others. In the process, food has become a weapon. Instead of “taking care of the garden, dressing and keeping it” (Genesis 2:15), we have exploited and abused the good things God gave us.

The world continues to reject the teachings of Jesus, replacing them with selfishness, greed, and a moral code that teaches “survival of the fittest.” The result is that we all reap the consequences of what we have sown. Bringing people to believe in God and Jesus Christ not only has meaning in terms of what lies beyond this life, but it also is at the root of the quality of life we and our descendants will have in the future. Science and technology can’t solve all of our problems as long as greed and stupidity get in the way.

Greenland Stromatolites and Faux Fossils

Greenland Stromatolites are Faux Fossils but this one is real.An old joke which showed up periodically during my college graduate work said, “Be sure your data conforms to your conclusions.” Because grants and scholarships depended on having success in your scientific research, it was tempting to cherry-pick data to support whatever you were claiming about your topic. That problem is still with us, and it has shown its head in reports of Greenland stromatolites.

Stromatolites are fossil deposits made by algae. (The picture shows a stromatolite fossil.) We see them not only in some shallow marine environments today, but we also find them in some of the oldest rocks on Earth. The Gunflint Chert along Lake Superior in Ontario contains some of the earliest stromatolites, but the rocks in Greenland are even older. Because many theories of the development of life on Earth depend upon finding marine life forms in Earth’s oldest rocks, there have been several premature news reports of Greenland stromatolites.

Abigail Allwood is recognized as an expert on stromatolites and has studied the oldest known stromatolites in Australia. She went to Greenland to examine the Greenland stromatolites. She concludes that they are not fossils, but only rocks that have experienced a great deal of tectonic activity. Ms. Allwood collected rocks just a few feet from the claimed stromatolites and found significant evidence of diastrophism, a type of plate tectonics which deforms Earth’s crust. She found no evidence of real fossils.

Naturally, the authors of the original paper on the Greenland stromatolites disagree with Allwood, but that is the way science works. Scientific testing answers the questions of authenticity and eventually reveals the truth. Unfortunately, false religious theories are frequently untestable and stay in existence for a very long time.

In science and faith, we should follow the evidence wherever it leads. It appears that in the case of the Greenland stromatolites, we have faux fossils and not the real thing.

Properties of Light

Properties of LightWhen you open your eyes in the morning, take a minute to thank God that you can see. We should reflect upon how good it is to have light instead of the darkness of night. The properties of light make it unique and special.

I am keenly aware of my gift of sight because of a long association with Glynn Langston, who is blind and manages our outreach to the visually impaired. In my lectures, I frequently refer to Edwin Abbott’s book Flatland to help people understand dimensions and how the spiritual is different from the physical. Glynn was born blind, so he is unable to visualize the concept of a sphere crossing a plane and leaving the outline of a circle. He has been kind about it, but my wife once said to me, “How do you expect a blind man to visualize anything!” Even those of us who can see have trouble understanding the properties of light beyond what meets the eye. Radio waves, gamma rays, X-rays, ultraviolet rays, and infra-red rays are all light!

The properties of light make it difficult to comprehend. The most general definition of light is that it is the energy released when a charge changes momentum. The bundle of energy released is called a photon, and the amount of change in momentum determines the energy of the released light. Even in the visible spectrum for humans, the different colors we see are determined by how much energy the light has. Violet has much more energy than red. Ultraviolet has more energy than violet. X-rays and gamma rays have even more energy, but they are still light. Infrared, and radio waves have lower energies than red. That is why infrared warms you and ultraviolet gives you a sunburn. It is also why radio waves can pass through the walls of your home without causing damage and gamma rays can also pass through things, but they will do significant damage.

In the creation process, there had to be special accommodations for the properties of light coming to Earth from the Sun and from outer space. The ozone layer had to be in place to absorb ultraviolet and avoid damage to life. The eyes of every living thing that uses some form of sight had to be designed to function in the part of the spectrum that fit its diet. Rattlesnakes, for example, have specialized sight organs to see in the infrared. Because they eat rodents whose bodies give off radiation in the infrared, a rattlesnake can see its prey on the darkest night. Nearly every insect sees some part of the spectrum other than the colors visible to humans. That is how a mosquito finds you and how insects navigate at night.

Not every star in the sky gives off the properties of light that are needed for life to exist. Some stars radiate in the X-ray part of the spectrum, and others radiate energies too low to be useful to life. Even our trees and shrubs require light in the green part of the visible spectrum to know when to shed their leaves in preparation for winter. In Job 38-41, God spoke to Job to show His wisdom and design and convince Job of his ignorance. Many of the designs God pointed to are connected to light. “Where is the way where light dwells, and where is the location of darkness?” (38:19) “By what process is light parted which scatters the east wind upon the earth?” (38:24) “How does the eagle seek the prey and see that which is afar off?” (39:29)

The Bible speaks of light that is not produced by the acceleration of an electric charge. The most important of these is described in Matthew 5:14-16: “You are the light of the world … let your light so shine before men that they may see your good works and glorify your Father which is in heaven.” Let those of us who are Christians not only be amazed by God’s design of the properties of light and the world in which we live, but let us also strive to be the light Jesus calls us to be.
