Asteroid Strike from Space

As our view of space and our solar system improves, astronomers have realized that space is a dangerous place. Space travel requires considering the many ways astronauts can be harmed when they leave Earth’s protection. It isn’t just cold and radiation and the damaging effects of weightlessness, but our solar system is full of rock material left over from the creation process. NASA must keep in mind the possibility of an asteroid strike from space.

NASA has plotted 1000 known “Potentially Hazardous Asteroids” (PHAs). These are documented boulders of rock and ice over 140 meters across that will pass within 7.5 million kilometers of Earth (about 20 times the distance to the Moon). Were a giant asteroid to strike Earth, the result would be catastrophic. There is evidence that this has happened in the past, probably causing mass extinctions on our planet.

NASA used the DART (Double Asteroid Redirection Test) mission in 2022 to explore the possibility of redirecting an asteroid away from the Earth. We are talking about a large object, not the small pieces of rock and dust that strike the Earth every day, producing meteor displays and fireballs. NASA designed DART to find a way to prevent a catastrophic asteroid strike from space.

NASA has concluded that none of the asteroids known to astronomers will strike the Earth for at least the next 100 years. God created our planet in such a way that we are protected from destructive agents from outer space. The more we learn about space, the more we see the design and planning involved in creation.

The threat to humanity is what we do to ourselves, not any failure in the design of our planet. God has also given us a way to protect ourselves from each other, and we see that in the teachings of Jesus Christ. Read Matthew chapters 5-7, and you will see what Jesus told us. The selfishness and greed of humans threaten our existence individually and collectively. Human self-destruction is far more likely than a catastrophic asteroid strike from space.

Chondrite Meteorites from Space

What are the odds of you getting hit by a rock that came to the Earth from Mars? A New Jersey woman named Suzy Kop walked into an empty bedroom in her house and found a hole in her ceiling and a still-warm six-inch potato-shaped rock on the floor. Scientists studying it have concluded it is one of the rare stony chondrite meteorites, dating back to the beginning of the solar system.

The word “chondrite” comes from the Greek “chondres,” meaning sand grain. Such rocks from space contain tiny, millimeter-sized granules, iron and nickel alloys, and as much as 50% silicate minerals. There are several different kinds of meteorites. Some are called “irons” because they are almost entirely made of iron and nickel alloys. Others, called “stoney irons,” have silicate minerals in addition to iron and nickel alloys. In addition, carbonaceous chondrite meteorites contain water, sulfur, and even some organic material.

In their excavations of ancient cities, archaeologists have found knives and various other objects made of meteoric iron material. Ling before humans learned how to smelt iron to make tools and weapons, they found iron meteorites and pounded them into useful tools. (See “Metal From the Heavens” in National Geographic for June 2023, pages 102-104.) Genesis 4:22 refers to Tubal-Cain, a son of Lamech, “who forged all kinds of tools out of bronze and iron.” However, early humans used iron meteorites long before Tubal-Cain forged tools.

The question of why there are different kinds of meteorites is of greater interest. The answer is that the meteorites came from the formation of different objects in various places in the cosmos. Scientists believe iron meteorites came from the cores of asteroids or planets where extreme heat would allow only resistant metals to exist. Silicate minerals were probably ejected from planets with less heat and lower pressure. Some stoney chondrite meteorites have the same chemical composition as Mars, so they probably came from that planet.

In 2018 the Japanese Hayabusa2 spacecraft brought back samples from the asteroid Ryugu. The samples contained uracil, which is a building block of RNA. Some astronomers believe a planet exploded and that many meteorites, as well as Ryugu are what remain from that explosion.

Researchers are sampling other asteroids, but the message is that space is full of the remains of God’s creative actions. Likewise, the existence of planet Earth and the life on it tells us that this is indeed a unique place that we need to care for and preserve.

The Mystery of Oumuamua

An interesting space mystery circulating since 2017 has been the story of an outer space object named Oumuamua. This object is shaped like a cigar, is dark in color, and has an unusual orbit. Astronomers in Hawaii first discovered it and gave it the name “Oumuamua,” which means “scout” or “messenger” in Hawaiian. Part of the mystery of Oumuamua is deciding what it is – perhaps an asteroid or a comet. Oumuamua is smaller than most comets at 300 to 3000 feet (100 to 1,000 meters) long. It has no visible tail, as most comets do. A surprising thing about Oumuamua is that as it orbited the Sun, it sped up and accelerated away from it.

The media jumped on the scientific announcement of Oumuamua. Tabloids predicted it was an alien spaceship that picked up hydrogen from the Sun, and that’s why it accelerated. We have repeatedly pointed out that nothing in the Bible tells us whether or not there is life in outer space.

Like most tabloid stories, there is no reported scientific explanation of what Oumuamua is and why it behaves as it does, apparently tumbling through space. Comets have a great many volatile materials frozen inside them. When the Sun heats them, those materials vaporize, creating a small force, but usually not enough to alter the comet’s path.

We can learn some lessons from the mystery of Oumuamua. One is to be very careful about what you read in the media or hear on TV news broadcasts. A more important message is that there is a lot of material left over from the creation process that is traveling through space. Space is not a pure vacuum, and capturing and analyzing some of that material could answer many questions about the science involved in the creation.

The most important message is that the universe is carefully designed, and we see signatures of that design everywhere we look. Oumuamua tells us a little more about the mysteries of space and the even bigger wonder of the intelligence that created it all. “The heavens declare the glory of God, and the skies proclaim the work of His hands” (Psalms 19:1).

‘Oumuamua and Space Aliens

Some people want to believe that everything we see and experience is the product of space aliens, and sometimes this belief ends up in tragedy. In March of 1997, a man named Marshall Applewhite convinced 39 people that a spaceship was following the Hale Bopp comet. He persuaded them to leave their physical bodies to join the aliens on the spacecraft. Despite tragic events like that, many people are investigating similar claims of aliens such as ‘Oumuamua.

In October of 2017, astronomers at the Haleakala Observatory in Hawaii observed a strange space object. They named it ‘Oumuamua, which is Hawaiian for “scout” or “messenger” because it apparently came from outside the solar system. Some thought it was an alien spaceship sent to investigate planet Earth. The object was traveling at 196,000 mph (315,000 kph) as it zipped through the solar system.

As astronomers continue to track ‘Oumuamua, they have found that it is accelerating as it heads out of the solar system. That fact has fueled more attention by those who believe it is not a natural object. It could be a comet, but astronomers have not observed a tail, which comets have. An asteroid is another possibility, but the trajectory does not show any connection to the Sun’s gravity as an asteroid would have. Why the object is accelerating is also not likely to match any asteroid or cometary explanation.

First, we want to remind you that life in space is not an apologetic or biblical issue. Years ago, I did a radio debate moderated by Larry King in Washington D.C. Someone asked my atheist opponent what he would do if a spaceship landed on the Whitehouse lawn and an alien got out with a Bible in his hand and said, “Has Jesus been here yet?” That would raise all kinds of other questions, but it does make the point that the Bible doesn’t tell us that Earth is the only place in the cosmos where life exists.

The current thinking about ‘Oumuamua is that it is a pancake-shaped piece broken off from a planet outside of our solar system. It has been speeding up because the Sun’s heat vaporized some solids, providing the acceleration force. There is no indication that alien intelligence is guiding ‘Oumuamua or that its composition indicates an unnatural origin.

If we would spend the same amount of time and energy encouraging people to get along with each other that we spend trying to get alien help to solve our problems, we might actually accomplish something. Jesus told us that He came so we could have “life and… have it more abundantly.” Following God’s Word instead of celestial objects like ‘Oumuamua can accomplish that.

Best Meteor Show of the Year

This year, 2020, has been a bad year for many things. However, it should be a good year for the Geminid meteor shower. It usually is the best meteor show of the year, but this year it might be even better. It will peak tonight in the late hours of December 13 and early hours of December 14.

If you are familiar with meteor showers, you know that they are caused when the Earth, on its journey around the Sun, passes through the remnants of a comet. As comets travel through our solar system, the Sun’s heat vaporizes the outer layers of those rocky snowballs leaving debris in the comet’s path. When our planet crosses that path, tiny rock fragments enter our atmosphere and burn up as friction with the air superheats them. The annual December Geminid meteor shower is different and not caused by a comet.

One difference is that the Geminids are younger than other annual meteor showers, which people have observed for hundreds or thousands of years. People first observed the August Perseids in A.D. 36. The Lyrids, which occur in April, were recorded by the Chinese in 687 B.C. However, the Geminids were first seen in December 1862. Since then, they have returned every year, and they have gradually become more numerous as they reach more than 100 meteors per hour.

So if a passing comet does not cause the Geminids, what does? Astronomers solved that mystery in 1983 when the Infrared Astronomical Satellite discovered a small asteroid, which they named Phaethon. It travels in a very elliptical orbit around the Sun in a little less than a year-and-a-half. That orbit takes it closer to the Sun than Mercury and then beyond Mars to the asteroid belt. The asteroid becomes superheated in its close pass by the Sun. Phaethon also spins on its axis about every three-and-a-half hours meaning that the surface fries as it faces the Sun’s heat and then freezes in the cold of space. The freezing and thawing crack the surface, and the centrifugal force throws out fragments.

Most of the particles resulting from the rapid temperature change and spin are probably only about a millimeter in diameter. For that reason, astronomers believe that Phaethon was struck by another space object in the recent past, causing more meteoroids, which could explain the Geminid show’s quality. This year should be better than average, because the Moon will be new, meaning we will have a dark sky. Another thing that makes the Geminids the best meteor show of the year is that they came in at a much slower speed, so they move more slowly across the sky.

If you have clear skies and can find a dark place with an open view of the sky, you could be in for a treat. However, for those of us in the north, it will be cold. Wear warm clothes, lean back in a lounge chair, cover yourself with a blanket, and be patient. According to the Royal Astronomical Society of Canada, the peak should occur around 8 p.m.EST December 13 (0100 GMT December 14). However, there should be plenty to see for hours before and after that.

As you look at the night sky, remember that the shepherd boy David was looking at the same sky around three millennia ago when he wrote, “The heavens declare the Glory of God, and the sky above proclaims his handiwork (Psalms 19:1).” I am sure that David enjoyed an open dark sky with no light pollution from electric lights, but he also didn’t get to see the Geminids, the best meteor show of the year.

Fake Asteroids and Space Junk

Politicians and the media often use the word “fake” in all kinds of dubious ways. Now we can apply the word to an asteroid known as 2020 SO (Space Object). It seems that this fake asteroid is just space junk.

There has been concern among astronomers for many years about the large number of rocks in our solar system. Right now, the International Astronomical Union’s Minor Planet Center has almost a million identified asteroids and comets, some of which could strike the Earth and cause massive destruction. The idea is that by cataloging these objects, we can know if any are on a collision course, so we might intervene to alter the trajectory.

It turns out that at least one of the cataloged asteroids is a fake asteroid. It is actually space junk. A NASA scientist determined that it is the upper stage of a Centaur rocket that put NASA’s Surveyor 2 lander on its way to the Moon in 1966. This rocket is just under 32 feet long and 10 feet in diameter and traveling at 1500 miles per hour. Another fake asteroid has turned out to be the third stage of the Saturn five rocket, which NASA launched in 1969 during the Apollo 12 mission.

Scientists are concerned about the amount of material that humans discard. That includes plastics that clutter the oceans and provide a constant headache at landfills. Chemicals dumped into rivers and lakes have had a very destructive effect on fish and other life forms, including humans. Space is also becoming more and more cluttered with human space junk. The material left from space launches is becoming a hazard to communications satellites and even space vehicles, including the International Space Station.

The need to make full use of everything and recycle is vital to our safety and health. When a terrible disease or deadly accident occurs, many people blame God. But more and more, we see that human neglect and carelessness causes most of our problems.

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.

Sinus Iridium on the Moon

Yesterday we mentioned that the Sun was at the exact angle to illuminate the Moon’s Jura Mountain Range. The effect is sometimes called the Golden Handle of the Moon because it resembles a small handle on the side. Since the sky was clear here in southwest Michigan last night, I took a picture of it. The tiny “handle” that you see is a semi-circular ridge surrounding a flat plain called the Sinus Iridium (Latin for the Bay of Rainbows). Sinus Iridium is actually an impact crater which has filled with lava, and the “mountains” that the Sun is illuminating is the edge of the crater.

In the NASA photo, you can see wave ripples on the surface as the lava flowed into the basin of the crater and hardened.

On our Does God Exist? educational tours of the Canyonlands we always visit Meteor Crater in Arizona. It is perhaps the best-preserved impact crater on Earth. At three-quarters of a mile (1.2 km) across, it is awe-inspiring to see. By comparison, the Sinus Iridium crater is 150 miles (240 km) across. You can also see several smaller impact craters that were formed after the lava flow.

As you examine the surface of the Moon, you will see that it is covered with impact craters caused by meteor and asteroid collisions. Earth has been bombarded with asteroids in the past. There is evidence of a large (93 mile, 150 km) impact crater called the Chicxulub Crater near what is today the Yucatan Peninsula.

Since Earth is a bigger target for impacts, why is Earth’s surface not pockmarked with craters like the Moon’ surface? Scientists have found evidence of about 190 impact craters on Earth. Most of them were early in Earth’s history, and erosion, plate tectonics, and other forces have hidden them from view. More importantly, we are protected from many of the impacts by our atmosphere. The heat from friction as a meteor enters the atmosphere at high speeds usually, but not always, causes them to burn up before they touch the ground. The more we see of God’s creation, the more we see His wisdom and power.

Billion-Dollar Picture

“A picture is worth a thousand words.” How often have you heard that phrase? It may very well be true, but this picture is worth more than that. What you see could be called a billion-dollar picture. At first glance, this picture may not look like much. However, you need to take a good look at the large white dot in the center. That’s us.

In September of 2016, the National Aeronautics and Space Administration (NASA) launched a spacecraft called OSIRIS-REx. The name stands for Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer. Its purpose is to study asteroids. Specifically, it was launched to study a near-Earth asteroid named 101955 Bennu. It will not only study the asteroid, but if all goes as planned, it will take a sample from Bennu and return that sample to Earth. The total cost of the project will be about one billion dollars, but it’s much more than a billion-dollar picture.

On January 17, 2018, OSIRIS-REx turned its NavCam 1 camera toward Earth and snapped this picture. The spacecraft was almost 40 million miles (63.6 million km) from Earth and traveling away at 19,000 miles per hour (8.5 km per second). The largest and brightest spot in the picture is Earth. The smaller dot close to it is our Moon. The cluster of stars in the upper left is the Pleiades. In the top right is Hamal, the brightest star in the constellation Aries. Surrounding the Earth and Moon are five stars that are the head of the whale in the constellation Cetus.

OSIRIS-REx reached the vicinity of Bennu on December 3, 2018. It will be orbiting the asteroid and scanning the surface looking for a good place to land. That process will continue until July of 2020 when it will land and gather a sample. Scientists plan for OSIRIS-REx to deliver that sample to Earth in September of 2023.

Scientists hope that by studying the asteroid sample, they will learn more about the formation of our solar system. They hope to learn more about asteroids in general and what we might do to prevent one from slamming into our planet. There is also hope for mining useful minerals from asteroids and getting a better idea of the history of Earth. The whole list of scientific objectives for this space probe is contained in that long name for which we use the acronym OSIRIS-REx.

Forgetting about the cost and ambitious objectives, we enjoy looking at this view of Earth from far, far away. It reminds us of what a big solar system and universe we live in and how amazing is the God who designed it all. It also reminds us of the challenge God gave to Job about the Pleiades in Job 38:31-33. We encourage you to read God’s entire challenge in Job 38:1 to 40:2 as you look at this billion-dollar picture.

Why So Much Stuff in Space?

One of the questions people ask about God’s creation is why so much stuff in space? If humans are the focus of God’s creation, why did He create so many planets, galaxies, and stars? If God’s purpose was to have the human race as the battlefield for the struggle between good and evil, surely He didn’t need to create 100 billion other stars in our galaxy and billions of other galaxies.

There are so many assumptions involved in this question that it would take many more pages to explore them all. First, this question assumes that God’s creation of life only happened here. It assumes that there are no other planets anywhere in the creation that have sentient beings living on them. You can argue that forever, but the Bible doesn’t give an answer. The Bible only describes Earth because it presents a message for our planet and its people.

The question also assumes that God only intended for us to live on the surface of this planet. I get letters regularly from people who suggest that we have no business going into outer space because God intends for us to live here and nowhere else. That is a massive assumption, and one that I suggest is misguided. One recent discovery has given another possible answer to why so much stuff in space. Humans are rapidly exploiting the mineral wealth of planet Earth. We know that the Earth contains a finite amount of iron, nickel, cobalt. If we should survive on Earth for much longer than the 21st century, we are going to run out of resources.

Japan’s robotic spacecraft Hayabusa 2 visited asteroid 162173 Ryugu (pictured) in June of 2018. Data from the spacecraft indicates that this asteroid is composed almost entirely of nickel and iron. The spacecraft was returning a sample to Earth for analysis. This asteroid is one kilometer wide, and at the current market value, the iron and nickel in the asteroid are worth over 80 billion dollars. God’s plan for us may be far greater and longer than we realize. Space contains a wealth of mineral resources. God has provided for us in many ways, and we always seem to have just enough of a resource to get us to the next source. We had just enough wood to get us to hydrocarbons, and just enough hydrocarbons to bring us to nuclear and solar power.

Our problem is not resources. Our problem is being able to get along with each other well enough to avoid destroying ourselves. Jesus Christ has the answer to that major issue, but the size of the cosmos merely reflects God’s power and wisdom. As we wonder why so much stuff in space, we have to think of the words of the psalmist, “What is man, that you are mindful of him? And the son of man, that you visit him? For you have made him a little lower than the angels, and have crowned him with glory and honor. You made him to have dominion over the works of your hands; you put all things under his feet” (Psalms 8:4-6).
