Lightning and Hydroxyl Radicals

Lightning and Hydroxyl Radicals

Lightning and hydroxyl radicals are among the lesser-known agents that clean our atmosphere. Hydroxyl radicals are composed of a single oxygen atom combined with a hydrogen atom. Since the valence of these two atoms is minus two and plus one, respectively, the combined charge is minus one. That means that the OH- radical will attach itself to any plus-charged atom or molecule. Numerous molecules in our atmosphere offer a positive charge, such as carbon monoxide and methane. Also, many organic compounds have loosely held hydrogen atoms. When the hydroxyl radical attaches itself to another hydrogen atom, the product is water.

Even if you don’t understand all of the chemistry involved here, it should be evident that the materials the hydroxyl radicals attach themselves to are common atmospheric pollutants. Hydroxyl is an air cleaning compound designed to remove natural contaminants and human-caused pollution as well. In typical situations, the concentration of hydroxyl radicals is a few ppt (parts per trillion). Keeping our atmosphere free of damaging pollutants requires much more than that.

Recent discoveries have shown that lightning produces significant numbers of hydroxyls. In 2012, a NASA jet flying through storm clouds over Colorado, Oklahoma, and Texas detected hydroxyl concentrations of thousands of ppt. Electricity from lightning can produce enough hydroxyl radicals to keep our air clean of any natural pollutants and help to reduce human-caused pollution.

We have said before that lightning takes nitrogen from the atmosphere and produces nitrates that provide essential nutrients for plants. Now we know that lightning is also indispensable as an air cleaning tool. With lightning and hydroxyl radicals, God has designed a tool that not only allows plants to provide our food but also cleans our air.

Unique and Bizarre Planet Earth

Unique and Bizarre Planet Earth

“Planet Earth – Unique And Bizarre.” Those are the words used by Astronomy magazine (June 2021, page 21) to describe the results of studies of the planets within and beyond our solar system. Why is Earth a unique and bizarre planet?

We have four terrestrial planets in our solar system. In addition to Earth, they are Mercury, Venus, and Mars. Those planets have smaller masses than Earth, ranging from Mercury with 5.5% of Earth’s mass to Venus with 81.5%. They also have radically different atmospheres. Venus, which is closest to Earth’s size, has an atmosphere that is 96% carbon dioxide. Mars, roughly half of Earth’s size, is 95% carbon dioxide and 2.7% nitrogen. By contrast, Earth’s atmosphere has 78% nitrogen, 21% oxygen, and less than .1% carbon dioxide.

NASA stationed an observation satellite at the Lagrange point between Earth and the Sun. That is the location where Earth’s gravity balances the Sun’s gravity. The satellite will remain stationary at roughly a million miles from Earth, gather data, and compare Earth data with information from other solar systems. It shows that Earth is the only planet we know of with abundant liquid water driving an active water cycle. 

Scientists believe life itself is responsible for much of the design of planet Earth. Earth’s vegetation has taken whatever carbon dioxide was in our atmosphere and turned it into oxygen. It is no coincidence that the Genesis account portrays plants as the first thing to appear after God created the dry land and seas. 

Another factor making Earth a unique and bizarre planet is the abundance of minerals. Earth has massive minerals of all kinds. Meteorites contain a very small number of minerals, and the Moon has more than the meteorites, but far less than Earth. The media tends to suggest that everything in space is like what we see on Earth, but the data that scientists are gathering shows that our planet is radically different. 

At the end of each day of the Genesis account, God said, “it is good” (Genesis 1:10,12, 18, 21, 25). The first chapter ends with God saying, “it is VERY good.” Over and over, the Psalms call our attention to how unique our planet is. “When I consider the heavens, the work of your fingers, the moon and the stars, which you have ordained; what is man, that you are mindful of him, and the son of man that you visit him” (Psalms 8:3-4). Psalms 19:1 adds, “The heavens declare the glory of God, and the sky shows his handiwork.” 

Our unique and bizarre planet was created by an Intelligence that shaped it into the one place that can support human life, not only in our solar system but perhaps in the entire creation.

K2-141b Is Not Another Earth

K2-141b Is Not Another Earth

In their desperate attempt to find an inhabited planet, some media people have jumped to the conclusion that any planet close to 8000 miles (13,000 km) in diameter will be inhabited. One of the candidates orbiting a star in our galaxy is called K2-141b, and it is reasonably close to us in size and location, a little under 200 light-years away. However, K2-141b is not another Earth.

Astronomers have discovered that its atmosphere has all the elemental components of rocks. That has to mean that the surface temperature of the planet is hot enough to vaporize rocks. That would be more than 5400 degrees Fahrenheit (3,000 C). K2-141b is not another Earth.

At this time, when people are concerned about global warming, we must consider how many factors on Earth and the surrounding area give use the proper temperature for life to exist. Without the variables that keep our planet cool, we could not have a surface temperature of less than 212 degrees Fahrenheit (100 C). The size, temperature, and activity of the Sun have to be just right. The amount of ocean surface that reflects solar heat back into space is crucial. The factors that restrict greenhouse gases, the relatively low value of volcanic activity, the lack of exothermic chemical reactions, the reflectivity of clouds, and many other factors all influence our temperature.

Even though K2-141b is not another Earth, there may be other planets with conditions that permit surface temperatures between 0 and 100 degrees Celsius, allowing liquid water. But evidence shows that such planets are rare, and their design would be from the same source as our planet. If God has created life elsewhere on a planet that will allow life to exist over the long haul, it will be another demonstration of incredible wisdom and design. Our planet is exceptional, and taking care of it should be a high priority for all of us.

Tiny Living Things that Make Life Possible

Tiny Living Things that Make Life Possible

The natural world is incredibly complex, with a staggering number of things that we are not even aware of. Every cubic meter of air above a grassy field can contain more than 100,000 living things, many of which we can’t see. We seldom realize that it is these tiny living things that make life possible.

In 2008, Dr. Thomas Kunz at Boston University helped to establish a new scientific discipline called aeroecology. Dr. Kunz and his team used radar, telemetry, thermal imaging, and acoustic monitoring devices to study our lower atmosphere. Other scientists have continued studying aeroecology, which provides useful information in biology and such diverse areas as weather, wind turbines, conditions around airports affecting airplane safety, and disease control.


Aeroecology also involves controlling and maintaining insect populations. Insects are pollinators, and they are critical in a variety of food chains. Recent problems with bee die-offs have affected food production in many areas. Birds and bats help control airborne insects, and their survival is essential to maintain healthy conditions for the success of farming. A purple martin will eat about 20,000 insects yearly, which means this one species removes roughly 412 billion bugs from the atmosphere every year. Some birds stay in the air eating bugs for months at a time, like the alpine swifts of Europe and Africa. They can fly continuously for up to seven months while eating, drinking, and even sleeping.

All of this atmospheric life has a direct bearing on our bodies. We take in massive numbers of bacteria from the atmosphere. Studies by the germ-free research center at Notre Dame University have shown that microbes are critical for life. Researchers found that germ-free rabbits were unable to reproduce. Babies exposed to antibiotics during the first six months of their lives are prone to being overweight. A lack of microbes alters the serotonin levels in humans, affecting many areas of our health. Healthy humans have 1000 microbial species in their mouths and more than 10,000 species in their digestive systems.

The bottom line is that the life of a plant or animal is not just about the organism itself. It is also about the tiny living things that make life possible. The air and the soil are full of these supporting organisms. This indicates design by an Intelligence far beyond what humans can comprehend.

As we get more and better tools to look into the very small, we are astounded by their complexity and function. The Bible simply says God created life. We don’t see any detail, nor should we expect to. How would you explain bacteria to a man with no microscope? “We can know there is a God through the things he has made” (Romans 1:20). Our ability to understand the tiny living things that make life possible leaves us in awe of what God has done.

Radiation Levels on the Moon

Radiation Levels on the Moon

God created planet Earth for us to live on, and He designed us with what we need to survive here. The more we learn about conditions elsewhere in the solar system, the more we see how unique Earth is. Recently we have seen research data concerning radiation levels on the Moon. Our studies reveal that astronauts on the Moon could get up to 1000 times more radiation than what we experience on Earth.

Dr. Kerry Lee at the Johnson Space Center in Houston has analyzed data from a Chinese-German team. The Germans used data retrieved by a Chinese lander named Chang’e 4. They compared it with data from a NASA orbiter that has been circling the Moon for over ten years. The two sets of data agree 100%. The primary risk factor for humans is cancer. The message is that if humans try to exist on the Moon, they will need thick-walled shelters for protection.

We take for granted the romantic idea that humans can wander around space, looking for new information about the stars and planets. In doing that, we fail to realize how carefully designed the Earth is to avoid the dangers of radiation in space. Astronauts in the International Space Station get three times less radiation than the radiation levels on the Moon.

Our upper atmosphere and magnetic field help to shield us from radiation. God carefully designed the Earth with features to protect us from radiation from the Sun and other stars. Proverbs 8:22-30 finds wisdom speaking about the creation. The more we look out into space, the more we see the necessity of wisdom in making a world where we can live safely.

Our Atmospheric Shield

Our Atmospheric Shield

One of the fantastic and vital features of planet Earth is our atmospheric shield. We have often mentioned the NASA website Astronomy Picture of the Day (apod.nasa.gov). Every day NASA posts a different astronomy picture to show us something of the cosmos. This is an excellent service because most of us don’t have access to giant telescopes, and we can’t see light in wavelengths outside of the visible spectrum.

On September 12, 2020, NASA’s posting showed a time-lapse series of pictures taken by the New South Wales observatory in Australia. This observatory is located at 33 degrees south latitude in an area with minimal light pollution, so there is minimal obstruction of the night sky. The pictures were recorded on 372 nights and run like a movie. What you see are sporadic meteors, fireballs, meteor showers, and even a lightning sprite. The series shows over 1000 meteors.

Remember that this picture sequence shows a relatively small area of sky. This does remind us that there is a constant rain of dust, pieces of rock, and other debris coming down upon our planet. People working with communication satellites are well aware of this because of constant damage to the orbiting objects. For those of us on Earth’s surface, our atmospheric shield burns up most of the solid space material. We don’t have to worry about getting hit by space debris or getting sandpapered by the small dust particles coming from outer space. That is just the solid stuff. Our atmospheric shield also refracts away non-solid radiation such as x-rays and gamma rays.

Providing a place where life can exist is not as easy as some think. One of the reasons we are not finding life in outer space is that designing and implementing our atmospheric shield was vital for the existence of life, and doing that was not simple. It required intelligence and a carefully implemented design. The simple statement, “In the beginning, God created the heaven and the Earth” doesn’t tell us the incredible difficulty of doing that.

Earth’s Atmospheric Design

Earth's Atmospheric Design

One of the many things that make our planet uniquely well designed is the atmosphere. Our atmosphere has the right density to burn up the 10,000 plus meteors that speed into it every year. It’s also dense enough to scatter the cosmic rays and X-rays from space, so we are protected from this deadly radiation by our Earth’s atmospheric design.

Also very important, the atmosphere is thin enough to allow light to penetrate so plants can grow. It contains the proper mix of gasses for all living things to use. There is enough oxygen for us to breathe, but not enough to cause dangerous, uncontrolled combustion. It has the right amount of carbon dioxide to allow plants to live and give us the right amount of the “greenhouse effect.” This proper amount prevents too much heat from radiating off into space, keeping Earth at a temperature that promotes life.

The atmosphere is mostly nitrogen, which is relatively inert, but plants need it to grow. Because nitrogen is inert, it’s released to the soil by bacteria and certain plants, such as legumes or by lightning or tectonic activity. The atmosphere is topped off with a layer of ozone that absorbs ultraviolet energy from the Sun to keep us from being overexposed to the harmful effects of UV rays.

When we look at Earth’s atmospheric design and compare it to that of other planets, we realize that God has given us just what we need for life on this planet.

Planetary Atmosphere Variations

Planetary Atmosphere Variations - Earth

The dominant theory for the origin of the planets in our solar system assumes that they all evolved from a single mass or nebula. Several factors support that idea. Those factors include the fact that the planets lie roughly in one plane, that they all revolve around the Sun in the same direction, and that there is mathematical predictability to their location. Most of the irregularities that might indicate against a common source, such as variations in planetary tilt, have reasonable explanations. However, new planetary atmosphere variations are difficult to explain.

Recent studies of the atmospheres of the terrestrial planets have shown wide variations. Our atmosphere contains 78% nitrogen, but nitrogen on Venus is 4%, and on Mars, it is 2.7%. Both Mars and Venus have atmospheres that are 95% carbon dioxide, while Earth is 0.1%, and Mercury has none. Earth and Mercury have oxygen in their atmospheres, 21% and 42% respectively, but Venus and Mars have less than 1%.

Astronomers theorize that they can explain these planetary atmosphere variations.
They suggest that the atmospheres are not original to the planets, but were produced by processes that took place after the formation of the planets. The best guess now is that impacts and outgassing formed the atmospheres. This is not a trivial matter because life is not possible without the proper combination of atmospheric gases.

The Genesis account describes the production of Earth’s structure in a sequence. Genesis 1:6-9 indicates separate creations of the hydrosphere, atmosphere, and lithosphere. The new data support the idea that once Earth was created, continued activity prepared it for life. Once again, we find the scientific evidence in support of the Bible’s description.

Value of a Whale

Value of a Whale - Humpback Breaching

Many years ago, an atheist challenged my statement that everything in the creation had a designed purpose and filled a need. My atheist friend insisted that the whale is one example of a poorly designed creature with no purpose. He said that they eat massive amounts of the ocean’s food that could be eaten by other, more useful creatures. He also challenged that they contribute nothing to the ecology of the oceans. At the time, I didn’t have a good answer to why whales are useful. Whale oil seemed to me to be a weak answer. Since then, I have learned the value of a whale.

One of the things I love about science is that it continues to look for understandings of the world in which we live. New studies of whales have revealed some facts that show the whale is incredibly useful. The current winter edition of Defenders of Wildlife magazine reports data on the value of a whale.

Whales live a long time, and they accumulate carbon in their bodies. When the whale dies, it takes that carbon to the ocean bottom, removing it from the atmosphere. New research shows that each whale takes 33 tons (30 metric tons) of carbon out of the atmosphere. By comparison, a tree absorbs 48 pounds (22 kg) of carbon dioxide a year. In 60 years, which is the lifespan of most whales, a tree would remove one ton of carbon from the air. Whales play a role in removing the greenhouse gas that people are concerned about today.

In a whale’s lifetime, it will bring minerals to the ocean surface to stimulate phytoplankton growth. This plankton contributes more than 50% of the oxygen we breathe and absorbs 37 billion tons (33.5 metric tons) of carbon dioxide a year. Phytoplankton also sustains many fish species, and today, fishing is a 150 billion dollar industry.

So what is the value of a whale? Defenders of Wildlife maintains that each whale is worth more than two million dollars. God has a purpose for everything He created, but sometimes it takes us a long time to understand how His creatures help us.

Earth’s Twilight and What It Means

Earth's Twilight

The part of Earth’s atmosphere we live in, fly airplanes in, and which contains over 90% of our oxygen is called the troposphere. It is much thinner than you may realize. Earth’s diameter is about 8,000 miles, and the thickness of the troposphere is much less than eight miles, making it one one-thousandth of the diameter of Earth. Our air is like an onion skin around our planet. Earth’s twilight daily reminds of the thin blanket that protects us.

You might wonder if the thin nature of our atmosphere is not a risk to us. The truth is that our troposphere is a uniquely designed structure, and if it were any different, life could not exist on this planet. The troposphere has to be…

…thin enough to allow enough light in for the photosynthetic processes of plants, but thick enough to burn up hunks of rock from space as they are pulled in by Earth’s gravity.

…thick enough to provide oxygen to breathe, but not so thick as to create pressures that would cause oxygen toxemia.

…thick enough to trap enough of the Sun’s heat to keep us warm, but thin enough to not overheat us.

…thick enough to refract and scatter dangerous radiation away from us, but thin enough to allow critical wavelengths to reach Earth’s surface for biological purposes.

…thick enough to allow water to exist as a liquid, but not so thick that other gases liquefy or dissolve in water,


These are just a sampling of the critical elements involved in the design of the troposphere. There are additional layers above the troposphere that do other things to support life on this planet. As science has examined the atmospheres of other planets within our solar system, we see that they are very different. The acid air and greenhouse effect of the atmosphere of Venus has turned it into a hellish environment. We do not have the ultraviolet light that bathes and sterilizes Mars because our ozone layer filters out much of that destructive component of the Sun’s light.

Each day as we watch Earth’s twilight come, we should be reminded of the incredible wisdom built into the structure of our atmosphere. As the sky turns from blue to a brief green, to yellow, to orange, and then red, we are seeing the longer wavelengths which we don’t see in the daylight because they are mixed in our atmosphere. Our air keeps X -rays away from our planet. Its density allows flight and keeps the lakes and oceans from evaporating. Its low density allows it to move and carry warmth and moisture from one area of our planet to another so that life can exist from the equator to the poles. Earth’s twilight is a daily reminder of the care and design built into our planet because of God’s love and wisdom.
