Planet Parade Syzygy

Just before sunrise Monday morning, June 3, 2024, six planets and an asteroid will form a “planet parade.” That means they will appear in a straight line as viewed from Earth. The planets involved are Mercury, Jupiter, Uranus, an asteroid, Mars, Neptune, and Saturn, going from the horizon up. Understand that is how we see them from Earth because Mercury and Jupiter are nowhere near each other.

With the naked eye, you should be able to see Mars, Saturn, and Jupiter, with Jupiter being the brightest. With binoculars, you might be able to see Uranus. With a telescope and knowing where to look, you will see all seven; if the sky is clear, you are away from light pollution and have a clear view of the eastern horizon. However, a crescent moon will make viewing a little more difficult. By Thursday, the Moon will be out of the way to better view the planets, but Mercury and Jupiter will have switched places. The change of position will be caused by the outer planets (Jupiter) appearing to move more slowly than the inner planets (Mercury).

The planets’ ability to appear close together in the sky shows how flat our solar system is. In other words, the planets orbit the Sun in nearly the same plane rather than in random directions. That fact allows the outer planets, especially Jupiter, to serve as comet sweepers, protecting Earth from dangerous objects coming in from beyond the solar system.

A syzygy is a true alignment of planets, which happens very rarely. This planet parade is an interesting apparent alignment, and “syzygy” is a good word to remember the next time you play Scrabble. This beautiful view of our solar system reminds us of God’s wise artistic and engineering design.

Protection from Incoming Space Objects

One of the exciting features of our planet and solar system is how they are built for life. The cosmos contains a lot of material left over from the creation process, and we have learned that volcanic eruptions and asteroid impacts can eject material into outer space. Fragments that appear to be cast off from Mars have been found on Earth. The need for protection from incoming space objects like asteroids or comets is becoming more evident as scientists discover the enormous amount of damage done by the few collisions Earth has sustained.

Most people have heard of the asteroid collision scientists believe caused the extinction of the dinosaurs. However, evidence exists of earlier collisions that shaped and molded our planet. The recent experiment to alter the path of an asteroid by slamming a spacecraft into it shows the concern many have that an asteroid could crash into Earth and wipe out all human life.

During the last week in August of 2023, NASA’s Juno spacecraft confirmed an amateur astronomer’s report of seeing an object slamming into the surface of Jupiter. This is the third recorded sizable object impact on Jupiter, creating a fireball visible from Earth. In 1994, astronomers observed fragments of the Shoemaker-Levy 9 comet hitting Jupiter, and in September 2021, astronomers observed another collision.

Jupiter is strategically located and so massive that its gravity draws in asteroids, comets, and other materials that would cause a major disaster if they struck the Earth. Some objects don’t actually hit Jupiter, but they come close enough that Jupiter’s gravitational field slings them out of the inner solar system. Journalist Passant Rabie wrote on Yahoo News, “The solar system’s gas giant certainly knows how to keep peace in its cosmic neighborhood.”

We suggest that when God designed and created the solar system, He gave Earth protection from incoming space objects, which has kept humans safe for our entire history. Between Jupiter, Saturn, Neptune, and Uranus, it is almost impossible for a large object from outside the solar system to hit our planet.

The number of things that had to be “right” for our planet to support life is enormous. The more we discover, the less likely it is that pure accidental chance can explain them. A better explanation is, “The heavens declare the glory of God; the skies proclaim the work of His hands” (Psalms 19:1).

What Syzygy Means

Syzygy is an interesting word used in astronomy. It’s a great word for Scrabble, but my kids quit playing with me when I used it once. You might wonder what syzygy means. Let me explain.

This spring brings an unusual view of the solar system. If you get up before the Sun now through May, look to the east, and you will see four planets that shine very brightly. The planets from left to right are Jupiter, Venus, Mars, and Saturn. All of them will be bright enough to see with the naked eye. With binoculars or a small telescope, you will also see some of the moons of Jupiter and Saturn. Astronomers call an alignment of planets like this a syzygy.

We can see these planets in this rare alignment because they orbit the Sun in the same plane, called the ecliptic plane. This is not just some happy accident but is a critical factor in the survival of life on Earth. Objects coming into the solar system along the ecliptic will not collide with Earth because the planets that lie further out in the solar system will intercept them long before they can reach our planet.

We have actually seen Jupiter intercept a comet coming toward the Sun along the ecliptic. The fireball the impact produced was larger than Earth’s diameter. This solar system design is so complete that the gravitational fields of the outer planets overlap so that nothing from outside the solar system can get to the Earth. The only “planet” not in the ecliptic is Pluto, which is inclined to the ecliptic. For that reason, scientists say that Pluto is not a planet but a captured object.

The design of the solar system is far more complex than most of us understand. The more we travel in space, the more we see the effect of not having a designed protection system. As science deals with space travel, the wisdom and planning of God become apparent. Take a few minutes on a clear morning before the Sun comes up to go out and look and wonder at how “The heavens declare the glory of God” (Psalms 19:1). Now you know what syzygy means, and you can use it the next time you play Scrabble.

Our Essential Moon and Life on Earth

For most people, our Moon is just a light at night. The fact is that our essential moon is part of Earth’s fitness for life. Any change in the size, distance, or obit of the Moon would be catastrophic for life on Earth.

Having just one moon of significant size is a very unusual situation. Venus has no moons, and the two tiny moons of Mars are apparently captured asteroids. Jupiter, Saturn, and Uranus each have multiple moons, many of which are of significant size. However, a single large moon is unique to planet Earth.

So what does our essential Moon do for us? Because of its size, it has a significant gravitational pull on the Earth. That pull is strong enough to cause our planet to flex as the Moon orbits it. That creates a disturbance in geologic activity on Earth when the Moon is over an area of unstable rock.

The Moon’s pull on Earth’s waters is more significant. The Moon’s pull stirs the oceans much like a person might stir a large saucepan of soup. Our Moon causes many ocean currents and tides, even in large lakes. Ocean currents not only move nutrients around but transport heat as well. For example, the Gulf Stream is critical to marine life along the east coast of North America and controls temperatures along the entire coast.

The Moon’s gravitational pull is closely related to its mass. Therefore, a larger moon would cause massive flooding along the edges of continents. If it were smaller, the tides and currents would not be large enough to clean the estuaries or warm the landmasses, and many marine lifeforms would not survive.

If we had more than one moon, they would affect each other. There are rock tides causing moonquakes on the Moon due to the pull of Earth’s gravity. A second moon would amplify this effect, and if the two moons collided, the fragments would threaten life on Earth. Every total solar eclipse reminds us how precise the Moon’s size is. It can exactly cover our view of the Sun, allowing us to see and study the Sun’s corona.

Most of us overlook how our essential Moon’s size, mass, distance, and orbit shape seem to be carefully designed. Attributing that precision to blind chance requires faith as great as attributing life to chance. We would suggest that the Creator used his wisdom, described beautifully in Proverbs 8:1-5 and 22-32, to design an Earth/Moon system that allows life to exist and prosper on planet Earth.

Water in the Milky Way Galaxy

We recently reported that there are massive amounts of water in the cosmos. Now, more evidence points to water in the Milky Way Galaxy.

An asteroid belt exists between Mars and Jupiter. Astronomers believe that this belt of material is either a planet that disintegrated or one that never formed because of the gravitational pushes and pulls of Jupiter and Mars. In 2007, NASA launched a probe called Dawn. In 2015, it arrived at one of the largest asteroids named Ceres. The Dawn probe revealed several strange white spots, especially in the Occator Crater. In August of 2020, astronomers presented several papers dealing with evidence that the white spots are ejections of salty water produced from holes punched into Ceres’ surface by space rocks.

Alan Stern of the Southwest Research Institute was involved in the NASA research on Ceres. He is quoted as saying that this discovery is “one of the most profound discoveries in planetary science in the space age.” The Occator Crater is 57 miles (92 km) wide. The material erupting through fractures looks very much like Utah’s Great Salt Lake.

Astronomers suggest that our solar system has large amounts of water stored in the moons of Jupiter and Saturn and Pluto’s surface. Trying to put together a model that explains the formation of wet moons and objects like Ceres is proving to be quite difficult. It appears that whatever the cause, our solar system has a unique water signature.

The abundance of water in the Milky Way Galaxy may turn out to be very important if humans venture into space and start establishing colonies on other worlds. Did God prepare a stepping stone for humans to move beyond Earth’s limitations by placing essential water in our solar system? Perhaps, but as we have said before, we face many other challenges as we venture away from our home planet.

Massive Amounts of Water in the Cosmos

One of the things that has entered the debate about life in space has been the presence of water. Astronomers have found methane, ethane, and other compounds in oceans on other planets and moons in our solar system. Unlike water, they are not polar molecules. The polar structure of water makes it an apparent necessity for life. Scientists have debated about whether water has existed or does now exist on Mars, our Moon, or one of the many moons of Jupiter and Saturn. Now there is evidence of massive amounts of water in our solar system.

We have posted before about NASA’s “Astronomy Picture of the Day” website (apod.nasa.gov). On January 15, 2021, the page showed this picture taken by the New Horizons spacecraft on July 14, 2015, as it flew by Pluto. The photograph shows areas of frozen nitrogen and carbon monoxide. It also shows massive amounts of water ice frozen into mountains reaching up to 11,000 feet (3,353 m), which is comparable to mountains on Earth.

There is more and more evidence that, at least in our solar system, water is quite common. Because of the temperatures in the outer planets, that water is in a frozen state. Liquid water has a very narrow range of temperatures, and that means the zone in which a planet can have liquid water is very small. Because of that, life on another planet is improbable, but the potential for humans establishing or supporting life elsewhere is relatively high.

Verse two of Genesis 1 tells us that the early Earth had water in the liquid state: “And the spirit of God moved upon the face of the waters.” Massive amounts of water apparently dominated the planet. Verse six tells us that there was “a firmament in the midst of the waters” that divided the waters. It isn’t until verse nine that dry land appears. The keyword in these verses is the word translated firmament in English. The Hebrew word used here is “raqia.” It is used nine times in Genesis 1 and eight times elsewhere in the Old Testament. Four of those eight are in the visions of Ezekiel 1:22-26.

The Bible’s economy of language leaves us to understand the “firmament” from its context. The most accurate understanding is what, in modern terms, we would call an “interface,” a zone of change. In many cases, that zone is the atmosphere, so in verse 20 of Genesis chapter one, we have birds flying in the firmament. Genesis 1:14-15 tells us that the Sun and the Moon became visible as the darkness (Genesis 1:2) of the cloud cover (Job 38:8-9) in the firmament cleared. Ezekiel saw his chariots in the firmament.

The discovery of mountains of frozen water elsewhere in the solar system indicates that the original cosmos had massive amounts of water, as Genesis 1:6 implies. It also tells us that when the Earth’s temperatures settled to between zero and 100 degrees Celsius, the water became seas covering the planet. This is one more evidence for the integrity of the Genesis account as it describes the creative design of God, simplified so that all humans can understand it.

Planetary Atmospheric Pressure

The media often overlook how many things have to be “right” for life to exist on a planet. Planetary atmospheric pressure is one factor.

By “life,” we mean the standard textbook definition of organisms that can move, breathe, respond to outside stimuli, and reproduce. The problem is that many conditions make other terrestrial planets (planets with hard surfaces) unlikely to harbor life. Life is even less likely on Jovian planets that are primarily gaseous. You can postulate balloon-like living organisms in Jupiter or Saturn’s atmosphere, but radiation and electrical problems make that unlikely as well.

Planetary atmospheric pressure depends on the weight of the gases above a planet’s surface. The air pressure on Earth’s surface is 14.696 pounds per square inch a sea level. That pressure allows water to exist as a liquid, and it will enable various gases to dissolve in the water. We all know what happens when you shake a bottle of carbonated beverage and then quickly remove the cap. The sudden drop in pressure causes an explosion as the dissolved carbon dioxide escapes from the liquid. For organisms to absorb oxygen dissolved in water, which fish do, the atmospheric pressure must be high enough for the oxygen to dissolve. The atmospheric pressure on the surface of Mars is .01 of the pressure on Earth. That means water on Mars would contain no oxygen or dissolved gases.

There has been discussion about finding water on the Moon or Mercury, but those atmospheric pressures are considerably lower than those on Mars. That means water would not be in a liquid state. On the other end of the pressure spectrum is Venus, where atmospheric pressure 92 times greater than on Earth. At that pressure, toxic gases would be dissolved in any water that existed on the planet.

Planetary atmospheric pressure is just one more variable that must be carefully and precisely chosen when constructing an environment that will support and sustain life. The creation is far more complicated than most of us realize. As we learn more, we must stand in awe of the God who created our planet.

Star of Bethlehem and the Planetary Conjunction

People give many different explanations of what the ”wise men” saw that led them to the Christ child. (See Matthew 2:1-12.) One of those explanations says there was a planetary alignment in the constellation Virgo (the Virgin). Since the magi may have been Zoroaster astrologers, they knew Christ had been born and followed “the star.” There is no connection between the star of Bethlehem and a planetary conjunction.

This December 21, at the winter solstice, there is a conjunction of Jupiter and Saturn. If you go outside about an hour after sunset and look to the southwest, you will see that the two planets are separated by less than a minute of arc, even though they are hundreds of millions of miles apart. If your eyesight is not very good, they may look like one very bright star.

This planetary conjunction is an exciting astronomical event, but it is not a good explanation of the star of Bethlehem. Whatever the magi saw, it could not have been a celestial star. Herod could have seen a celestial star for himself and would have had no reason to question its appearance as Matthew 2:3-10 describes. He could have had his people follow the star to find Christ and kill him.

Matthew 2:9 tells us that the star “went before them until it came to rest over the place where the young child was.” The closest star to planet Earth, outside of the Sun, is Proxima Centauri, and it is 4.2 light-years away. No stars move that way, and a planetary alignment is not a star.

The Bible does not present the star of Bethlehem as a natural object but as a miraculous act of God. Anytime the Bible says something is a miracle, it becomes a matter of faith, not science. How Jesus rose from the grave is not something we can scientifically explain. You either accept it, or you reject it, but all attempts to explain it naturally fail–and there have been many.

The star of Bethlehem was a miracle to show God’s acceptance of the Gentiles and to give Mary and Joseph the resources to move to Egypt and avoid Herod’s infanticide. The star of Bethlehem was not a natural event, but today’s planetary conjunction is. As we said yesterday, today’s event is not an omen and has no religious importance, but it is a rare, predictable astronomical event.

Wandering Stars in the Sky

The ancient Greeks saw the five visible planets and called them “wandering stars” because they moved randomly across the sky instead of staying in fixed positions like the stars. The word “planet” comes from the Greek word for “wanderer.”

We have known for many centuries that the planets are not stars. They appear to wander because they orbit the Sun, just like our planet Earth. They orbit at different speeds, making them appear to wander in the sky. For astronomers to classify a celestial body as a planet, it must meet three requirements:

It must have enough mass for gravity to cause it to become spherical, unlike an asteroid.
It must not have enough mass to cause thermonuclear fusion, which would make it a star.
It must have cleared the area of debris known as planetesimals.

We have five planets that are visible without the aid of telescopes or even binoculars. Two of the visible planets are called inferior planets, not because of importance but because their orbit is inside Earth’s orbit. They are Mercury and Venus. The other three are known as the superior planets since they are beyond Earth’s orbit. They are Mars, Jupiter, and Saturn.

There is one essential thing the ancient Greeks did not understand about the solar system. They did not know that it is orderly. The Greeks saw a pantheon of gods controlling various aspects of the Earth and skies. Each of their gods had all of the bad traits of humans struggling with each other. It was the Judeo-Christian concept of one almighty and wise creator God who created an orderly system that led to the scientific understanding of the cosmos.

Today, we can study and understand the wisdom of God in creation. Because of that, we can know where the planets and stars, as well as solar and lunar eclipses, will be visible at any given time and from any location on Earth. Those “wandering stars” are not wandering after all.

Making Molecules on Jupiter

In recent years we have come to understand how God formed many of the elements that make up our world and our bodies. We watch stars producing new elements, and we realize that this system was designed by God to take the hydrogen produced in the beginning and continually make heavier elements by thermonuclear fusion. It is incredible to witness the power and design in a nova or supernova and to understand that this is God’s forge to make new elements. Now we have another picture of a design God has used for making molecules.

Molecules are combinations of atoms put together to produce a compound. Simple compounds like water and methane are difficult enough to produce. The huge molecules, such as amino acids that make up living materials, require a particular environment to form. Many of them have been found in space debris, but their origins are not clear.

The latest NASA report on Jupiter has given us some new understanding of making molecules. NASA’s robotic Juno spacecraft orbits only 15,000 kilometers above Jupiter’s cloud tops. Using new data from this spacecraft, astronomers have announced that Jupiter is apparently mostly liquid. It is not a ball of rock with a blanket of liquids and gases, as Earth-based observations seemed to indicate.

It’s hard to realize the size of Jupiter (2.5 times the mass of all other planets combined), its rapid spin rate (more than twice as fast as Earth’s), the amount of lightning that we observe, and the extreme temperatures are all working in a liquid. It indicates an environment similar to what we can create in our laboratories here on Earth to produce complex molecules. The Miller-Urey experiment of 1953 earned a Nobel prize for producing an environment in the lab capable of making molecules of amino acids. Now we see a location in space that duplicates much of Stanley Miller’s famous experiment. To be facetious, perhaps God should get a Nobel Prize for something that was operational long before any human existed.

The more we know of the creation, the closer we get to the Creator. Knowing His methods just increases our wonder at His power and wisdom.
