Cassini Exceeded Expectations

Saturn with its rings and some of its moons.Cassini Exceeded Expectations

On the morning of September 15, 2017, Cassini ended its life in fiery destruction. Cassini was a space probe orbiting and studying Saturn, and by all measures, Cassini exceeded expectations.

NASA, the European Space Agency, and the Italian Space Agency worked together on the Cassini-Huygens space exploration project. The mission was to study Saturn along with its moons and rings. NASA launched the spacecraft in 1997, and it arrived near Saturn and went into orbit around that planet in 2004.

The Huygens (pronounced hoy-guns) lander module, provided by the ESA, separated from the Cassini probe and landed on Saturn’s largest moon, Titan, in 2005. The parachute landing was successful, and the probe sent out data for about 90 minutes. In that brief time, scientists learned much about the surface of that distant moon. Viewed from Titan’s surface, the Sun appeared about the size and brightness of a car headlight 150 meters away. The Huygens probe took pictures and told us that Titan’s surface is dotted with rivers, lakes, and oceans made of methane and ethane. It also has dunes up to 300 feet (91 meters) tall.

Meanwhile, the Cassini probe continued to orbit Saturn and send back amazing and beautiful pictures of its rings and moons for 13 years. Cassini helped us to learn more about the moons of Saturn. The planet has at least 53 moons and possibly eight more. We learned that the moon Enceladus is covered with a liquid water ocean with a surface layer of ice 19 to 25 miles (30 to 40 km) thick. Geysers of water erupt from cracks in the ice. The rings of Saturn are a constantly changing collection of ice particles and small rocks. Saturn has hurricane-like storms at both poles and a hexagon-shaped jet stream at the north pole. How long is a day on Saturn? That’s hard to determine because it is a gas planet and not all parts of it move at the same speed. Scientists estimate a little more than 10 hours.

Cassini exceeded expectations by surviving seven years of travel to Saturn plus 13 years orbiting the planet. As it ran out of fuel, scientists sent it hurtling into Saturn’s atmosphere to burn up so it could not contaminate any of Saturn’s moons by crashing into them.

We are fascinated by the Cassini photos and scientists will continue to study them for years. The picture we posted shows a Cassini view of Saturn and its rings with a bright spot visible below the rings. That spot is the planet where we live. As we look at the hostile environment of space and the other planets, we realize how incredible Earth is. God has given us a place with everything we need for life. You might say that compared to any other place in the universe, Earth exceeds expectations.

Autumn Equinox and Season Design

Autumn Equinox and Season Design
We have just passed the autumn equinox and what we call “the first day of fall.” It will be late December before fall officially ends at the winter solstice. On the first day of fall here in Michigan, it was unseasonably hot, and people were griping about “where is the cool fall weather we are supposed to have?” Long before the first day of winter on December 20-21, we will have snow. Is there something wrong with the seasons, or is the trouble with our understanding?

“Equinox” suggests that the length of the day is equal to the length of the night. The Sun is overhead at the equator, and from now until December 20 it will be directly overhead at progressively greater southern latitudes until it reaches just past 23 degrees south latitude. Here in the north, the Sun’s elevation above the horizon will get progressively lower, meaning that less and less of the Sun’s energy will strike the Earth’s surface so the weather will get cooler.

The problem with this simple picture is that there is a lag in the seasons. During the summer months in the Northern Hemisphere the lakes and oceans warm from the sunshine. Water has a high specific heat, so that heat is stored and is released slowly. That means we stay warm longer than expected in the fall. In the Southern Hemisphere the picture is complicated by the fact that the Earth is closer to the Sun during their summertime, so the radiation is more intense. That might be a problem except that the Southern Hemisphere has more water than the Northern Hemisphere because oceans cover more of the southern Earth’s surface. With that greater storage and absorption capacity moderates the temperatures in the Southern Hemisphere.

The autumn equinox reminds us of the incredibly well-designed system of the Earth. It is easy to over-simplify the seasons and the equinoxes and solstices, but the system functions remarkably well. Without that careful design, the weather picture would be far more unstable than it is. Proverbs 8:22-31 speaks of wisdom’s involvement in all of the creation. We are just now beginning to understand how the system works and how our use of Earth’s resources affect the system.

Great American Eclipse “Engineered”

The Great American Eclipse
One month ago today a total solar eclipse crossed the United States. The so-called Great American Eclipse had many interesting things associated with it.

We have pointed out in previous discussions that people have attached all kinds of erroneous connections to eclipses. Some people have suggested that the eclipse predicts the doom of kings and in recent weeks the demise of Donald Trump. We have seen religious prognostications of all kinds attached to the eclipse including the second coming of Christ. There are those who have denigrated biblical events such as the darkness at the time Christ died, saying it was just an eclipse. (No eclipse can last for three hours.) None of these claims and predictions have any value.

One message that should stand out from the eclipse is the precision that God has built into the creation of the cosmos. How can astronomers predict when eclipses will occur including the exact time for a given location? This is quite simple if you understand the design of the creation. Astronomers have a grid in the sky that is an extension of the latitude/longitude system on the surface of the Earth. All objects in space, including the Sun and the Moon, can be plotted on this grid system. This allows scientists to plot the movement of the Moon and the shadow the Moon casts on Earth. (Remember that a solar eclipse is the Moon’s shadow on the Earth.)

Many of us earth science teachers use the Earth Science Curriculum Project. It has a lab where students plot an eclipse and predict what kind of eclipse will occur. They can predict when it will start, how much of the Sun will be covered, and when it will end. One of my students commenting after doing the lab, “Wow, what engineer thought up this system?” Another student responded “No engineer did it. God did it!” The first student responded, “Well God is a pretty cool engineer!”

We have pointed out that one of the problems people have with faith is that they attempt to explain everything as mysticism and magic. When it becomes obvious that planning and design are part of the system, that understanding erodes their faith in God. A good magician can mystify us, but still, he is using methods we can understand if we learn how he did it.

The Great American Eclipse spoke well about how precisely and carefully God has designed the planetary system in which we live. The eclipse is one more witness to the statement that, “The heavens declare the glory of God; the skies proclaim the work of his hands” (Psalms 19:1).

Space Dimensions and Lunar Motion

Space Dimensions and Lunar Motion
We have had several questions and comments precipitated by the eclipse on August 21. Most of them centered around the fact that the Moon’s motion across the Sun was so slow. In reality, the lunar motion is very fast. The speed is a function of the Earth’s rotation as well as the Moon’s revolution around the Earth. However, when compared to space dimensions, lunar motion can seem slow.

The Moon moves with an orbital speed of 2,288 miles (3,683 km) per hour, taking about 28 days to complete its journey around the Earth. Although that sounds fast, it is quite slow in relation to the size of the cosmos. Other moons going around other planets travel at higher speeds. Io, one of the moons of Jupiter, whizzes completely around the planet in less than two days. While our Moon travels at the speed of a rifle bullet, it is 80 times slower than the speed of meteors. Saturn travels ten times faster than the Moon.

The reason we are not aware of the speeds involved is because of the incredible size of the creation. We see meteors moving fast because they are close to us. Meteors are pieces of space junk whizzing through our atmosphere so quickly that they burn up from friction with the air. The moon is over 239,000 miles (384,633 km) away, so its motion appears to be much slower.

When we look out into the night sky, we are looking far into the past. By the time we see the light from stars like Albireo, that light has traveled 430 light-years. That star is actually two stars spinning around each other. Even though they are orbiting each other and astronomers have been watching them since the seventeenth century, we have not seen them change position.

Space dimensions are beyond our comprehension, and the size of the cosmos affects what we see and how we see it. Understanding that should give a whole new significance to the words of the song How Great Thou Art. It should also expand our understanding of, “The heavens declare the glory of God; the skies proclaim the work of his hands” (Psalms 19:1).

Hurricanes and God’s Design

Hurricanes and God's Design
Our hearts go out to everyone who has been affected by the recent storms in Texas and Louisiana. Our family has members who were flooded and have sustained a terrible loss. The total damage to innocent humans is so massive it is hard to comprehend. Please do not interpret this discussion as being callous, unfeeling, or minimizing the loss that so many have suffered. However, we need to consider the cause of hurricanes and God’s design for life on Earth.

When something like this happens, we receive communications either blaming God or wanting to know why God has allowed it to happen. We would not pretend to have all the answers to the questions that a disaster like this raises. However, this is not a vindictive act of God or retaliation for some human sin. It is a natural product of the design of our planet.

The design is a very good. Spreading water around the Earth in such a way that all latitudes and longitudes have enough water for humans to survive is a difficult challenge. When the Sun is directly overhead at the Equator, it generates heat energy on the surface of the Earth at that locale. The heated air rises and cools. Moisture condenses, and precipitation occurs.

The now dry air moves north and south away from the tropical rain forests. Eventually, it falls back to the Earth at about 30 degrees latitude north and south of the equator. That means there will be a desert at 30 degrees latitude. If you look at a globe, you will see that most of Earth’s deserts are at 30 degrees latitude. This effect is called “The Hadley Cell” and is well understood.

In the United States, 30 degrees north runs through Houston, the gulf coast, and northern Florida. Those areas would be deserts except for hurricanes and God’s design. Low-pressure cells generate over the South Atlantic and move toward the Gulf of Mexico. If these cells pick up enough water due to extra heat, a hurricane can result. Hurricanes bring large amounts of water to what would otherwise be parched, dry areas. When these areas go a long time with no significant water-bearing storms, drought is the result.

When I was a child in the middle of the twentieth century, hurricanes were a time for celebration. Hurricane parties were the rage, and people knew how to “batten down” for the “big blow.” The barrier islands were covered with mangroves which would break up the storm surge. Recharging the aquifers in the area was a good thing for everyone.

Since those days, people have cut down the mangroves and built resorts and beach houses on those barrier islands. Without the mangroves, the storm surges are massive. People have built huge housing developments on land poorly protected from the sea. Even farther inland, massive numbers of people have been put in harm’s way by the changes.

Hurricanes are not an evil, vindictive act of God. In this very incomplete and sketchy review of the cause of storm damage along the coast, we want to say that these storms have a positive effect. They are part of a system designed to make an area that otherwise would be a desert into a good place to live.

Like all the things God has given us, in the use of our land we need to apply wisdom. We have not had a good track record on stewardship of God’s gifts. We should think carefully about the future and use our knowledge and our ability to design and engineer things in a way that will minimize future catastrophes. Meanwhile, we need to join hands, clean up the mess, and help those in need.

Why Is There Color in Our World?

Why Is there Color in the World?
One of the joys of life is the beauty that we see in the natural world. The beauty of flowers is so great that we decorate our homes inside and out with flowers of every description. People will get out of bed early in the morning to watch a sunrise display colors of incredible beauty and complexity. We admire the work of artists and photographers who can capture a permanent record of the colors of the world on canvas or film. Why is there color in the world?

There are hundreds of papers that have been written by scientists and science writers concerning the reason for color. The design of the Earth and of the life systems on Earth frequently demand that certain colors exist. For example, the green in vegetation is necessary to protect plants from the high energy wavelengths of the Sun’s light.

There are some colors in the natural world, however, that seem to defy a naturalistic evolutionary explanation. Flowers living in identical environments will frequently have radically different colors. If we postulate that the colors are different to attract different pollinators, we run into logical problems. Wouldn’t the most efficient pollinators provide the same advantages to all flowers of similar geometric design? In caves deep in the ocean, there are some of the more vividly colored tropical fish. These fish never see sunlight and have no camouflage advantage given by their colors. There are worms and burrowing animals in thermal vents deep in the floor of the ocean that display rich and beautiful colors.

A skeptic may reply that these colors are a chance consequence of the materials that make up the bodies of these organisms. The fact is that, in many cases, the colored materials in the organism are inconsequential to the survival of the organism. We would suggest an equally plausible and perhaps more realistic explanation. Could it be that a God of intelligence and creative power designed the creation not only with functional wisdom but also with aesthetic intelligence?

Why is there color? God obviously enjoys beauty. We were created in God’s image, and therefore we enjoy the beauty of the world around us. Beauty is one of the things that makes our sojourn on this planet worthwhile.

Largest Land Animal-Titanosaur

Largest Land Animal
The first week of August a report was made in the Proceedings of the Royal Society B: Biological Sciences of perhaps the largest land animal that ever existed.

This dinosaur, found in Patagonia, Argentina, is named Patagotitan mayorum. It was more than 120 feet (36.5 m) long and weighed more than 76 tons (69 tonnes). It is also one of the most complete fossils with 150 bones recovered. When it is reassembled, the skeleton will be roughly the size of a Boeing 737.

What scientists want to learn about an animal of that size is, “How could it get so big?” We recently published a post about the world’s largest snake, the titanoboa. Reptiles, unlike mammals, continue to grow during their entire lives. In this case, the question is, “What sustains such massive growth?” How much food must the animal eat? How would its vascular system work? What is its significance to the ecology of the area where it lived? What environmental temperature and oxygen levels would allow an animal of that size to live? How could a human exist in such surroundings? Some of these questions are being addressed. Some are so complex that researchers on the site say it “is really hard to imagine” the answers.

We have pointed out that the ecological system that produced the resources humans would need to exist on this planet had to be different from what we have today. Those conditions would be hostile to human survival. This fossil of the largest land animal supports that point very well.

Origin of Life Problems Admitted

Wing Challenge to Origin of Life
One of the more honest and fair writers in modern scientific publications is Dr. Bob Berman. He has a regular column in Astronomy magazine and an interesting website. In the September 2017 issue of Astronomy (page 10), he has an outstanding brief review of the problems involved in trying to explain the origin of life. He begins by pointing out that the definition of “life” has been an issue because of questions such as whether or not a virus is alive. Viruses have no metabolism, they don’t feed or breathe, and yet they reproduce.

Berman then reviews some of the parameters necessary to consider when addressing the origin of life. Chirality is a major issue because amino acids that make up proteins come in right- and left-handed versions. Life on Earth is made up of only left-handed amino acids. Sugars used by the proteins are limited to the right-handed direction, and so is DNA. The wrong chirality just will not work to support life, so how could nature sort out the chirality? If life is easy to produce, why don’t we see it coming into existence all over the Earth? The “amoeba-to-man” model assumes that it only happened once, which conflicts with the view that life is abundant in the cosmos.

What is especially interesting is that Berman raises questions about the ability of evolution to explain on a chance basis some of the designs we see in living things. He uses the example of the airfoil that all flying forms of life have. The upper surface is convex using the Bernoulli effect to produce lift. The earliest bird and the flying reptiles all had a wing design that works. Trial and error would not work well to explain how the wing design would come into existence by chance. Berman points out that “some 400,000 cells would all have to simultaneously mutate in just the right way to create a properly shaped wing. This defies an evolutionary hypothesis.”

Berman concludes with the statement, “I’m not invoking spirituality, merely that the effect of random collisions and mutations is not always a workable answer. So perhaps nature is inherently smart.” I would suggest that wing design is just one of a massive number of design features that allow life to exist.

Berman quotes Francis Crick, the co-discoverer of DNA’s double helix as saying that the origin of life is “almost a miracle, so many are the conditions which would have had to have been satisfied to get it going.” We don’t invent a “god” to explain these things, but we would point to these things as one more evidence that there is a God and that blind chance is not a good designer of the complexity we see in the world around us.

Next Total Solar Eclipse 2024

The Next Total Solar Eclipse
The total solar eclipse of 2017 is now history. If you were in the United States, you probably saw at least a partial eclipse. If you missed the totality, you will have another chance in about seven years. The next total solar eclipse visible in North America will be on April 8, 2024.

The eclipse of 2024 will travel from south to north. After traveling across Mexico, it will cross the US border in Texas. It will travel northeast to follow the length of Lake Erie. Then it will skirt southern Canada and northern New England. It will leave the United States when it crosses Maine before crossing New Brunswick and Newfoundland and disappearing in the North Atlantic. Major US cities within the band of totality will include Dallas/Fort Worth, Indianapolis, Cleveland, and Buffalo. Although the 2017 eclipse was total for only about 2.5 minutes, the 2024 eclipse will last about 4 minutes in totality. You can get more details about it here.

However, the eclipse of 2024 will not be the next total solar eclipse in the world. Before 2024 there will be other total solar eclipses and partial eclipses in other parts of the world. You can find information about upcoming solar eclipses here and here. You will see the dates and times for solar eclipses up to the year 3000!

How can we predict solar eclipses with such precision, even hundreds of years in advance? The reason is that God has designed a solar system with stability and precision. Those factors also make possible the abundant life on this planet. Design, not chance is evident in the wisdom of creation.

Eclipses Are Not Omens

Eclipses Are Not Omens
By now everyone should know that there will be a total solar eclipse across the United States tomorrow. We have been writing about it in our posts for the past week. Please go back to any of them for more information. We hope that everyone knows that eclipses are not omens of some mysterious event. They are a natural phenomenon of the solar system that God designed.

The first written record of a total solar eclipse was in China in the year 2134 B.C. Apparently, that eclipse took everyone by surprise because two royal astrologers who failed to predict it, were beheaded for their crime. Since that time, people have often interpreted eclipses as omens or signs from God (or the gods) of some impending disaster. Human history has many instances of people interpreting an eclipse as a sign that something, usually bad, was about to happen. That is superstition and is not supported by the facts.

In recent years some Christians have declared eclipses, comets, or celestial alignments to be a sign that Christ is about to return or that God was about to send judgment on a nation. There have already been such claims about the total solar eclipse of 2017. That is both untrue and counterproductive for the Christian faith.

If you hear anyone saying that this eclipse is a sign of God’s judgment or Christ’s return, don’t believe it. Jesus made it clear that nobody knows when He will return. (Matthew 24:36 and Mark 13:32) We should always be prepared for Christ’s return because we can’t predict when it will be. It may be today, or it may not be in our lifetimes. Just remember that eclipses are not omens and neither are any other natural events.

Using omens or numerology or personal “revelations” to predict the end of the age and the return of Christ not only makes the false prophet look foolish, but it is a bad reflection on Christianity. It’s both bad science and bad theology. Nobody knows when Christ will return, but when He does, everyone will know it. (Philippians 2:10)
