‘Oumuamua: Mysterious Space Visitor

'Oumuamua: Mysterious Space Visitor
In October of 2017, astronomer Robert Weryk using a telescope in Hawaii discovered an object careening through our solar system from somewhere in interstellar space. Astronomers assumed it was an asteroid from some other stellar system in our galaxy. UFO promoters saw it as a spaceship from some other star system that was spying on our planet. The name given to it is ‘Oumuamua which is Hawaiian for “scout.”

The object was quite narrow and seem to be less irregular than most asteroids. Closer examination has shown that the surface of the object is a reddish color which is typical of some comets which have a crust covering an icy interior. Its size is approximately 800 by 100 feet (230 by 35 meters).

Studies of the trajectory of ‘Oumuamua show it is tumbling and changing directions in a way that indicates a force other than the Sun’s gravity working on it. Naturally, the UFO promoters were overjoyed saying that this proves that alien spacecraft are all around us, and we just happened to catch this one. The SETI Institute used its powerful Allen Telescope Array to examine the object but detected no radio signals indicating intelligence. The problem with the UFO idea is that the change of direction is much smaller than what rockets on a spacecraft would cause. The overall trajectory of ‘Oumuamua has not changed significantly as it heads out of the solar system. It is traveling to fast for any of our existing spacecraft to reach it, but it will still take 20,000 years to be completely clear of our solar system.

After much study, astronomers concluded that ‘Oumuamua is a comet. When comets get near the Sun, they spew gases from their interior. This jetting of gas always has some effect on the trajectory of the comet. The amount of change in ‘Oumuamua’s trajectory is consistent with the effect of a comet’s gas jets.

As we have emphasized before, the Bible doesn’t say that Earth is the only place in the universe where God chose to create life. At present, however, there is no credible evidence that there is life elsewhere, although microscopic forms may exist on Mars and some moons in our system. The idea of alien visitation is pure speculation with no evidence to support it.

The Lord tells us how to live in another existence. Read 1 Corinthians 15:35-57 to learn more about it. Waiting for an E.T. to come and whisk you away to a heaven is wishful thinking. Waiting for the Lord to come again has much more promise and much more supporting evidence.

Perseid Meteor Shower Peaks

Perseid Meteor Shower Peaks
In our post yesterday we mentioned that the Perseid meteor shower peaks tonight and tomorrow night August 11-12 and 12-13. Earth is making its annual journey through the trail of debris left by Comet Swift-Tuttle. When those pieces of rock, mostly ranging in size from a grain of sand to pea-sized, enter Earth’s atmosphere at supersonic speeds, they burn up from the heat of friction. We see the streaks as “shooting stars.”

Earth has been passing through the Swift-Tuttle debris since July 17 and will not be clear of it until August 24. So even though the Perseid meteor shower peaks this weekend, it is possible that you might see some of the meteors over the next few days. However, on these two nights, they should be visible at the rate of about one per minute. The best time to see them is after the Moon sets, and the best place is an area free of lights and with an open sky.

Every day anywhere from 100 tons to 1,000 tons of meteoritic material enters the Earth’s atmosphere. This material can come from comets or asteroids. The asteroid 3200 Phaethon produces the Geminid meteor shower in mid-December. There are other pieces of rock, dust, and debris in space that sometimes get trapped in the Earth’s gravitational field, and contribute to the hundreds of tons of material that reach Earth every day.

So what are the lessons we get from all of this? For one thing, Earth is not a static planet. It is gaining new mineral wealth every day. Our planet is vibrant and alive and has changed over the eons of its existence. The design of Earth’s defensive shield is incredible. With all of this material left over from the creation processes, it is critical that we have an atmosphere that is dense enough to burn up the space junk that comes toward us.

Every time scientists get a meteor sample we learn more about our neighbors in space. We knew a lot about the makeup of asteroids before science actually landed a spacecraft on one. Our knowledge of comets was advanced before we were able to leave Earth’s gravity and examine one up close. We continue to learn about the unique nature of the Earth, the Moon, the Sun, and the material that makes up our solar system.

While you are outside, take a look at Mars which is still closer and brighter than usual and visible until about 4 AM local time. Saturn will be visible until 2 AM. Venus will set about 9:30 PM and Jupiter at 11 PM. The planets travel near the ecliptic, the path of the Sun and Moon across the sky, so here’s your chance to enjoy them all. As the Perseid meteor shower peaks, it reminds us of the words of the psalmist: “The heavens declare the glory of God; the skies proclaim the work of his hands” (Psalms 19:1).

Why Such a Huge Universe?

Why Such a Huge Universe?
Here are some questions that are often asked by those who are skeptical of the existence of God: Why such a huge universe? How can we believe that a Creator cares about us when we are so insignificant in this vast cosmos? Those questions are worth considering.

There is no doubt that the cosmos is fantastically large. The Hubble Space Telescope aimed at a small area of sky no larger than one-tenth of the diameter of the Moon to take this Hubble eXtreme Deep Field photograph. The few bright spots with points of light radiating are stars. All the rest are galaxies—more than 10,000 of them in this picture! Some of them are as far away as 13 billion light-years, meaning that they were among the first galaxies formed.

If there are 10,000 plus galaxies in this tiny area of sky, that means there are 200 billion galaxies in the visible universe. Each of those galaxies contains an average of 200 billion stars. So why such a huge universe?

There were two critical factors at the beginning of cosmic existence—mass and expansion rate. If the total mass of protons and neutrons had been any less during the first moments of creation, hydrogen would not have fused into any elements heavier than helium. Then the nuclear furnaces of the stars could not have generated the elements carbon, nitrogen, oxygen, phosphorus, sodium, and potassium, which are essential for life. If the mass of protons and neutrons had been any greater at the cosmic creation, all of the original hydrogen would have fused into heavier elements like iron, and life would not have been possible.

The mass also affects the expansion rate. If the cosmic mass density had been less, the expansion rate would have been too fast to form stars like the Sun and planets like Earth. If the density had been greater, the expansion rate would have slower and all stars would have been much more massive than the Sun and would give off radiation too intense for any orbiting planets to sustain life.

In other words, the universe was fine-tuned from the moment it began! Why such a huge universe? Because it had to be. It has just the right mass and expansion rate for us to be here. We don’t think that was an accident. Through the study of astronomy and astrophysics, we can see HOW God created the universe we live in, and HOW He made it possible for us to live in it. The creation of the universe is not magic. It’s a feat of astounding engineering from the very moment of creation.

Special Star – Our Sun

Special Star – Our Sun
The Sun’s corona visible during the 2017 total eclipse.
Our Sun is a special star. In the past, scientists thought that it was just an average star. However, new studies in recent years have shown many ways that our Sun is unique.

A recent study by researchers at the Flatiron Institute Center for Computational Astrophysics under the leadership of astronomer Megan Bedell shows one more way that our star is unique. The study involved examining 79 “solar twins” of the Sun. These are other nearby stars that have nearly the same temperature and mass as the Sun. Using the HARPS telescope in Chile, they measured the spectra of each of the stars. A star’s spectrum of radiation indicates what elements the stars contain and the relative abundance of those elements.

The researchers measured the abundance of 30 different elements to a precision of two percent, which is higher than others had achieved. The ratios of elements such as carbon to oxygen and magnesium to silicon were nearly identical in the stars they studied, except for the ratios in our Sun. Our star has a lesser amount of metals and elements that make up rocks. Those elements are the ones which planets are made of, so we can probably assume that those elements were removed from the Sun to make Earth and the other rocky planets.

The stars which came closest to matching the Sun’s chemical composition were only a small portion of the total stars studied. They are also missing some of the materials that could build planets like Earth. However, in the search for exoplanets, astronomers so far have not found any planets orbiting those stars that are most similar to our Sun.

This study is fascinating, and there is much more to learn. We don’t know if science will ever find any potentially life-supporting solar systems and planets anywhere else. However, we do know that our Sun and this planet seem perfectly designed as a place for us to live and to study the vast universe. It is evident that we have a special planet orbiting a special star in a special place where we can observe and study God’s creation.

Search for Extraterrestrial Intelligence

Search for Extraterrestrial Intelligence
In 1960 radio astronomer Frank Drake began research to find alien civilizations in deep space by aiming an 85-foot radio telescope at some sun-like stars. He found nothing, but it was the beginning of a program known as SETI – Search for Extraterrestrial Intelligence.

The SETI program has continued through the years with many radio telescopes aimed at every area of space. In 1971 NASA funded a study that involved Frank Drake. They issued a report proposing Project Cyclops. That project would require the construction of 1,500 radio telescopes at the cost of ten-billion dollars. That project was never completed for obvious reasons. However, the concept of the report was used to continue the Search for Extraterrestrial Intelligence to this day with funding from various sources. Thousands of hours and millions of dollars have been spent with a net result of zero. No radio signals containing any intelligence have been detected–only noise.

Now there is “active SETI” in which scientists are sending radio signals toward distant stars. Frank Drake admitted that in 1974 he transmitted an encoded message toward a star cluster 25,000 light-years away in the constellation Hercules. Naturally, that message will arrive at its target in 25,000 years. If any intelligent being gets the message and responds immediately, it will take 25,000 years for the return message. Drake will not be here to receive that message in 50,000 years, and neither will anyone reading this.

As the search for extraterrestrial intelligence continues, is it possible that there really is an intelligent Being out there who is listening and waiting to hear from us? Is it possible that this Being is not limited by time and space? Is it possible that this Being is our Creator who has already communicated with us by becoming one of us? Is it possible that we are not listening?

Life Chemical Factory on Enceladus?

Life Chemical Factory on Enceladus
The picture shows Saturn’s moon Enceladus with Saturn in the background and part of a ring visible. Scientists are talking about a life chemical factory on Enceladus. One of the interesting questions about the origin of life is the question of how the chemicals needed to produce life came into existence.

Many believers in God answer that question just saying “God created them” and leaving it at that. For many of us with interest in science, that question expands to trying to understand HOW God created those chemicals. Saying that He spoke them into existence may be theologically acceptable, but the evidence shows that God used processes that we can understand.

Enceladus is essentially a vast ocean of water surrounded by a massive layer of ice. Scientists believe that powerful hydrothermal vents mix up the material found in the moon’s porous core with the salt water that makes up its vast ocean. This material is then ejected out into space in the form of enormous plumes of water vapor and ice granules you can see in the picture taken by the Cassini spacecraft. The sight is quite spectacular, and it was into one of these plumes that NASA’s scientists were able to send Cassini to examine their composition.

What the scientists learned is that the plumes contain organic materials. These are materials that are part of the building blocks of life. Therefore, this moon seems to be a factory that builds several of the ingredients needed to produce life.

Think of how factories produce cars. Factories at different locations all over the country build the parts. The parts come together in one place where highly skilled and creative engineers assemble them into a working automobile. In the same way, we can see a possible life chemical factory on Enceladus.

The more we explore space, the more we understand why these “factories” exist and how they have been used by “the great Engineer” to produce life on Earth.

Does Your GPS Work?

Does Your GPS Work?
Does Your GPS work? If so, you can give credit to Albert Einstein. In 1905 Einstein published the Special Theory of Relativity which said that nothing can travel faster than the speed of light. This presented a problem because gravity acts between objects instantly and thus it seems to be faster than the speed of light. It was a problem that needed a solution.

Ten years later, in 1915 Einstein revealed his General Theory of Relativity which resolved the problem. The explanation was that the Sun and planets cause space to curve around them and this warped shape of space influences the motion of other objects passing by them. That’s why the Moon orbits the Earth, and it’s why Earth and the other planets orbit the Sun.

This warping of space also bends light beams that pass through space. In 1919 British astrophysicist Arthur Eddington confirmed that Einstein was correct. Eddington observed the bending of light from distant stars as the light passed by the Sun during a total solar eclipse.

The understanding of how gravity bends space and light beams has given us methods of making measurements in space and detecting planets orbiting other stars. Einstein also said that time is warped by gravity causing time to move more slowly near massive bodies like the Earth. The effect of gravity on time allows Global Positioning Satellites to determine the exact position of the GPS receiver you use in your car.

Does your GPS work? If it does, it works because brilliant minds have discovered many of the amazing details of God’s creation. We have been able to apply the things we have learned, but science has only scratched the surface of understanding the work of the Creator.

Becoming New Creatures

Becoming New Creatures
The National Geographic Channel has been airing a very interesting new series of programs titled “One Strange Rock.” The series hosted by actor/comedian Will Smith tells about the many “strange” and “lucky” features of planet Earth that make it possible for us to live here. In the most recent episode, eight astronauts explain why they think that humans should colonize space. They and some other prominent individuals have recently suggested that colonizing other planets or living in space may be the only hope for the human race to survive. In the process we might find ourselves becoming new creatures.

This episode brings out the many ways that space life will affect our bodies. Based on present experience with the International Space Station we know that bones and muscles weaken when they do not have to overcome the effects of gravity. Body fluids shift upwards causing other physical changes. There are changes to a person’s eyesight which can be permanent. Outside of Earth’s atmospheric protection, astronauts face greater amounts of cosmic radiation that can trigger “light flashes” in their eyes. Long exposure to the higher levels of radiation may lead to cancer or brain damage. At the same time, bacteria grow faster and can become more deadly in a zero-gravity environment. The environment of space, even with the best protective gear science can devise, may at best be toxic and at worst fatal to humans.

Even with those considerations, the astronauts are saying that we must colonize space. Part of their reasoning is that humans have evolved to handle the challenges of life on this planet, and we will perhaps evolve becoming new creatures to handle the new hazards of space. They say it will just be a matter of adapting to a new environment. Will Smith said in this episode, “Even if we survive the journey and make the place feel like home, we still might not save our species. Just by being there we might turn into something else.”

I think that the real answer to human survival IS for us to turn into something else. Human survival depends on people turning away from their sinful passions and hatred. It involves becoming what God created us to be and living out the teaching and example of Jesus. Going to another planet and taking along our sinful nature with all of its baggage will not save us. The real hope for the survival of the human race does not involve leaving the planet God created for us. It does not require leaving Earth with all of its “strange” and “lucky” features that make life possible. It is not necessary for us to go to a much more hostile environment and evolve into new creatures. The answer to our survival is becoming new creatures here and now as described in 2 Corinthians 5:17.

Advanced Civilization Support

Advanced Civilization Support
We have often mentioned before the evidence that our planet was designed to support life. More than that, it was designed to support advanced life. It was even designed to support advanced civilization.

You can see evidence for advanced civilization support in the minerals of Earth’s crust—minerals that are essential for machinery and electronics that enable technology. One thing which perhaps you have not considered is how the size of our planet also supports advanced civilization. Among the achievements of science is space flight. The ability to use rockets to leave Earth’s surface makes it possible for us to place satellites in orbit. Those satellites include:

*Communication satellites which make possible nationwide and international television, news, sports, telephone, and video conversations.
*Global positioning satellites giving us GPS which we use for many purposes including airplane, ship, and personal navigation plus farming and safety uses.
*Weather satellites giving us advance warning of storms and helping to keep us safe.
*Observational satellites that allow us to study and learn more about our planet.
*Telescopic satellites which enable us to study our solar system and the universe.

We often fail to realize how important those satellites are for our advanced civilization. Also, the ability to use rockets to leave Earth’s surface allows us to send out space probes to explore our solar system and universe.

What does the design of our planet have to do with our ability to leave the surface? The answer relates to gravity. Astronomers have been looking for habitable planets orbiting other stars. They believe that they have found many of those exoplanets. However, the planets that are more likely to be located in habitable zones (where liquid water can exist) are much larger than Earth. A much-larger rocky planet would have much more mass and therefore much more gravity. Launching a rocket into space from such a planet would be much more difficult, if not impossible. Even airplane flight and the flight of birds could be affected by increased gravity.

A planet with a diameter 70 percent greater than Earth’s diameter would have ten times the mass. The advantage of having much more gravity would be that a planet like that could hold a thicker atmosphere which could give more protection from harmful cosmic rays and incoming asteroids. The disadvantage of a thicker atmosphere would be that it might also block useful solar rays. However, getting a rocket off the ground and into space could be prohibitive. It would require a much larger rocket which would require more fuel. That would require an even larger rocket to carry the extra fuel. The weight of the larger rocket and fuel would require an even larger rocket requiring even more fuel. This quickly spirals out of control.

So what is the conclusion? We live on a planet that is large enough to hold an atmosphere that protects us but small enough that we can to break the bond of gravity to go into space. A smaller planet would not have the atmosphere we need. A larger planet would not allow us to explore beyond our planet or even to send up satellites that help to make advanced civilization possible. As Goldilocks might say, “God made it just right.”

Buzz Aldrin and UFOs

Buzz Aldrin and UFOs
An article in the British tabloid Daily Star on April 8, 2018, claimed that new tests on Buzz Aldrin confirm that he contacted an alien on his trip to the Moon in 1969. The story supposedly came from an Ohio scientific group called “The Institute of BioAcoustic Biology and Sound Health.” That group claims to have a “top secret” test to determine what the subject actually experienced or saw. They gave no explanation of the test or why it overrules what the subject says.

The reason we even mention this is because atheist journals and even in major newspapers like USA Today have cited it. NASA has pointed out that four panels separated from the Apollo 11 spacecraft in flight, and they would have followed the same general trajectory as the spacecraft. Buzz Aldrin said in a Reddit chat session, “I feel absolutely convinced that we were looking at the sun reflected off of one of these panels.” He has denied having any contact with aliens. The BioAcoustic group claims that audio tests have shown hidden truths in Aldrin’s speech.

We have repeatedly pointed out that the question of whether there is life on other planets, is not a biblical or apologetic issue. The Bible doesn’t say that this is the only place where God has chosen to create life. However, it has become increasingly obvious that if there is alien intelligent life in space, it is too far away to be of any consequence to us. In spite of that, the media continues to push the idea that life in space somehow contradicts the Bible and supports atheism.

There is an adage that when a person doesn’t believe in something they will believe anything. That seems to apply here. Our focus needs to be on solving Earth’s problems, not attempts to divert attention to poorly supported scientific claims of alien intervention.
