Jupiter Is in Opposition

Jupiter Is in OppositionJune 10, 2019, is an excellent time to observe the largest planet in our solar system. The reason is that Jupiter is in opposition to our Sun.

When astronomers say that Jupiter is in opposition, they mean that planet Earth is passing between the Sun and Jupiter. At this time, Jupiter will rise in the east as the Sun sets in the west, and it will set in the west as the Sun rises in the east. In other words, Jupiter will be visible all night long, and it will be at its highest point in the sky in the middle of the night.

The picture was taken by the JunoCam on NASA’s spacecraft Juno which is currently orbiting Jupiter. NASA posts the raw images online and encourages individuals to download and process them. Citizen scientist Kevin M. Gill enhanced this one. You can find access to the raw images and see the work of other citizen scientists by clicking HERE.

When you see Jupiter in the sky tonight, it will not look like this picture, but it will be the brightest object in the sky. Jupiter is not a rocky planet like Earth. It’s a gas giant which if were 80 times more massive, would be hot enough to set off nuclear reactions in its core. Then it would be a star giving off its own light instead of just reflecting the Sun’s light. However, if you could lump all the other planets in our solar system together (including Earth), Jupiter would be 2.5 times more massive than them all.

Why do we need such a huge gas giant in the outer solar system? As we have said in previous posts, Jupiter is a comet sweeper. With its massive size and gravity, Jupiter protects us from objects such as comets coming from outside our solar system. In the 1990s, NASA observed Jupiter pulling apart and destroying comet Shoemaker-Levy 9. You can read about that in our previous post HERE. Jupiter also affects Earth’s climate cycles, which you can read about HERE.

Jupiter is in opposition about every 13 months. Last year opposition occurred in May. Next year it will be on July 14. If you miss seeing Jupiter tonight because of cloudy weather or any other reason, don’t despair. Jupiter will be closest to Earth on June 12, and it will continue to be visible, but right now it’s visible all night long.

While Jupiter is in opposition, or at any other time, look up and thank God that He has created such a marvelous and unique solar system to make life possible.

How Far Away Is the Sun?

How Far Away Is the Sun?Does it matter how far away the Sun is? Absolutely yes. The picture shows the order of the planets in our solar system, but not their distance from the Sun. So how far away is the Sun from Earth?

Any star that has planets orbiting it may potentially create a “habitable zone” where the light and heat are just right for the possibility of life to exist. Earth resides in the middle of the Sun’s habitable zone with Venus and Mars near the edge of the zone. Of course, there are many other factors required to support any kind of life, and it appears that Earth is the only planet in our solar system that has all of those factors. Earth has everything needed to support not just primitive life, but advanced life.

So what is the range of the habitable zone? That depends on the star. The size and brightness of the star are critical. Another essential factor is the type of radiation emitted by the star. Our Sun has the just-right radiation. Other stars may emit x-rays, gamma rays, or other deadly radiation in amounts that would destroy all life and prevent a habitable zone from existing.

Back in the eighteenth century, scientists determined the distance to the Sun by watching a transit of Venus across the Sun. Venus passes between the Earth and the Sun twice every hundred years or so. By measuring the time of the transit of Venus from two locations on Earth, scientists were able to use triangulation and simple math to calculate the distance to the Sun.

But the question was, how far away is the Sun? The Sun is about 93,000,000 miles (150,000,000 km) away from us. Since the speed of light is 186,000 miles (300,000 km) per second, it takes about eight and one-third minutes for the light from the Sun to reach the surface of the Earth. The energy the Sun delivers to our planet is just right to make life possible.

If someone asks you “how far away is the Sun,” you can say it is the “just right” distance. There are so many “just right” features of our planet that we can genuinely say we are in the “Goldilocks Zone.” Some think it was all just an accident, but we believe it was God’s plan and design.

Why Such a Large Universe? – Viewing Cosmological History

? - Viewing Cosmological HistoryWe have received some questions from readers who are perplexed by the fact that we frequently refer to a discovery or an event in outer space, millions of light-years from Earth. We have also mentioned NASA’s daily blog (apod.nasa.gov) showing gorgeous views of deep space objects many light-years away. Why such a large universe, and what does that mean to us?

It all comes down to viewing cosmological history. When we look through a telescope, we are looking at the past. If the next closest star exploded, it would be over four years before we would see it. You can see the light from the nearest major galaxy called the Andromeda, with your naked eye. It is two-million light years away, which means the light from that galaxy left there two million years ago. When we look at the sky, we are viewing cosmological history. Even the light from the Sun left there eight minutes ago. The question boils down to, Why such a large universe? Why did God create so much? It may seem presumptuous even to discuss that question. We would not attempt to speak for God who obviously can do whatever He wants to do. Nevertheless, there are some observations we can make.

First, it would be foolish to question whether the cosmos really is that large. There are a dozen different methods of measuring the distance to an object in space, and they all agree even though they are based on very different assumptions. The Doppler shift is very different from interstellar reddening which is different from cepheid variable measurements, but they all give the same answer for distances in space.

Some creationists suggest that God created the light that appears to be from a distant galaxy or star, already reaching Earth some 6000 years ago. In other words, what we see today when we look at the stars is essentially a video of something that never happened. We think we are viewing cosmological history, but we are being fooled. First of all, this explanation was invented to defend a denominational teaching that is not biblical. The Bible does not give the age of the cosmos or the Earth. No human calculation based on interpreting the Hebrew words in the Bible can stand up under examination.

However, the main problem with saying that God is trying to fool us is that such an explanation degrades God. From Genesis 1:1 to Revelation 22 the Bible repeats over and over that God is Truth. God does not lie, He does not mislead, and He does not misrepresent. James 1:13 says it well: “Let no man say when he is tempted, I am tempted of God, for God cannot be tempted with evil, neither does He tempt any man.” Faking an event in space that never happened so that humans could be fooled by it, would certainly be a deliberate effort to tempt honest, seeking humans into believing something that is wrong.

So why such a large universe? Why are we able to view the cosmological history of stars forming and dying? Why do we see billions of other galaxies beyond our Milky Way Galaxy? There may be multiple reasons known only to God. The ancient psalmist stated it well: “The Heavens declare the glory of God and the firmament shows His handiwork” (Psalms 19:1). The writer of Proverbs in chapter 8 has wisdom saying: “The Lord possessed me in the beginning of His way, before His works of old. I was set up from everlasting, from the beginning, before the Earth ever was…” (verse22-23). These statements and many more like them are not just expressions of ancient people. Here we are more than 2,000 years after Christ, and we are still trying to understand what electric charge is and what causes gravity. Moses couldn’t even see most of what modern science is investigating.

I would suggest that God structured the massive size of the cosmos and gave us the ability to watch matter being altered to produce stars and new planets so we could see His power and wisdom. Romans 1:20 rings true as we admire the work of scientists who help us understand that “the invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made….” Asking why such a large universe leads us to say, “I will praise you, Lord, for I (and the cosmos) am fearfully and wonderfully made: marvelous are your works” (Psalms 139:14).

Exoplanets and TESS

Exoplanets and TESS
Data is coming in from the Transiting Exoplanet Survey Satellite, known as TESS for short. It is the most powerful telescope ever deployed to look for planets orbiting other stars. Over two years, TESS can cover all 360 degrees of sky visible from Earth’s orbit. Our previous satellite called Kepler could only scan a small segment of the sky. Already Tess has identified over 300 probable exoplanets including one named HD 21749b which has the lowest known temperature for a planet orbiting a bright nearby star. (“Nearby” being 53 light-years away.)

The problem with this is that what astronomers consider “cool” is not cool from our standpoint. The surface temperature of HD 21749b is 150 degrees Celsius, which is way too hot for liquid water. (Water boils at 100 degrees Celsius.) A year on that planet equals 36 Earth days as it makes a complete orbit around its star. Most of the other exoplanets found at this time are vastly hotter than HD 21749b.

Astronomers have found other planetary systems, but they again have properties that would preclude any kind of life. Some of them have a planetary density equal to that of pure water. Some have orbits that are highly eccentric. Pi Mensae b, for example, has an orbit that varies widely. Its closest distance to its star approximately equals the distance from Earth to our Sun. The longest distance is similar to Jupiter’s distance from the Sun.

All of this continues to tell us that Earth is a unique planet orbiting a unique star. It is possible that those stars with exoplanets are undergoing an evolutionary process that could result in Earth-like planets billions of years from now. As we study them, we are learning more and more about what God did to create the “heaven and the earth.” God’s power and design become more amazing to us as we learn more about the universe. The more we learn, the more we see what Frank C. Baxter, who hosted the old Bell System Science TV Series, called “the wonder-working hand that has gone before us.”

Another Blood Moon

Another Blood Moon
This past Sunday night the Western Hemisphere experienced another blood moon. We often hear the phrase “blood moon” applied to total lunar eclipses. That’s because the Moon takes on an orange or red glow when the eclipse becomes total. It has nothing to do with blood and nothing to do with Bible prophecy. Lunar eclipses are natural phenomena which occur when the Sun, Moon, and Earth are in perfect alignment. Earth’s shadow falls across the Moon and gives it an eerie, orange glow.

I took this picture at about midnight local time when the temperature was hovering close to zero degrees Fahrenheit. Because of the cold, I didn’t get a good focus and didn’t stay outside very long. Numerous other people took better photos and posted them on the web. They all look similar since we were all seeing the same view. Our Moon always keeps the same face toward us. Some people refer to the back side of the Moon as “the dark side of the Moon.” However, there is no dark side. The Sun shines on the back side each time the monthly “new moon” occurs. The Moon is in tidal lock with Earth keeping the same side facing us year-round.

For those of us who live in North America, this will be the last total lunar eclipse for a while. We will not see another blood moon until May 16, 2022. (Asia, Australia, and the Pacific will see another blood moon on May 26, 2021.) Perhaps this will give us a little break from those who try to convince us that lunar eclipses are a prophetic sign. The only sign we see in total lunar eclipses is that the solar system God created is still working in the way He designed it to work. Days, months, seasons, and years (Genesis 1:14) continue as they will until God decides it is time to bring this present world to a close. And nobody knows when that will be.

Last July we posted an explanation of why the red color and what causes lunar eclipses. We encourage you to read that post by clicking HERE.

Martian Meteorite

Martian Meteorite
The picture shows a slice of a Martian meteorite. It landed in Morocco sometime in the past and was found there in 2011. On the edges, it shows evidence of the extreme heat of entry into Earth’s atmosphere.

How do we know that this piece of rock came from Mars? The Viking Landers analyzed the chemical composition of surface rocks on Mars, and the Mars Curiosity Rover examined the Martian atmosphere and argon level. Based on a chemical analysis of the element and isotope composition out of 61,000 meteorites found on Earth more than 130 give evidence of originating on the red planet. Their chemistry matches the Mars profile.

How did these meteorites get from Mars to Earth? They were dislodged by an impact of an asteroid on Mars which sent rocks flying out with enough force to escape the gravity of Mars. The surface gravity of Mars is only 38% of Earth’s gravity. After traveling through space, they were eventually pulled in by Earth’s gravity.

Some scientists have suggested that they detected evidence of organic (life) material in some Martian rocks. News media have been quick to attempt to say that this proves life existed on Mars in the past. Some even suggested that perhaps life came to Earth from another planet. However, further studies have disputed the organic origins or indicated that the organic evidence was actually picked up on Earth.

We have said before that the existence of life anywhere else in our galaxy is doubtful. At the same time, we have said that life elsewhere in the universe would not disprove the existence of God. We believe that God has the ability to create life anywhere He wants to, and He would not have to tell us about it. A Martian meteorite can only tell us that physics and gravity can do interesting things.

Comets and Cats

Comets and Cats
More than five years ago there was an event that reminded us of a comparison of comets and cats. The media proclaimed comet ISON “the comet of the century.” Experts predicted that it would outshine the full moon. Some said that it would be visible in daylight. Astronomy magazine predicted that it could “become the brightest comet ever seen by anyone now alive.” Excitement was in the air as people waited to see this remarkable comet in the fall of 2013. What happened to it?

Comets have been described as dirty snowballs in space. They consist of water ice, other frozen gasses, and rocks orbiting through the solar system. When they pass near the Sun, the solar radiation vaporizes the solids, and the vapor reflects the sunlight creating a visible ball called a coma. The solar wind causes the appearance of a tail pointing away from the Sun.

The comet that brought such excitement was named ISON after the International Scientific Optical Network based in Russia that initially discovered it. Because its perihelion (closest passage to the Sun) was going to be only 1.8 million kilometers in November of 2013, astronomers expected it to be a rare and “dazzling” sight. However, as the comet came close to the Sun, it disintegrated. What was left instead of being “fifteen times brighter than the full moon” was almost, or entirely, invisible to the naked eye. Star-gazers were disappointed.

Famed comet hunter David Levy made the statement: “Comets are like cats. They have tails, and they do precisely what they want.” Yes, comets and cats are unpredictable. However, one thing we know is that the design of our solar system makes it unlikely that one will collide with Earth. What the Sun doesn’t stop, the “comet sweeper” giant outer planets will—especially Jupiter which captured one of the comets that David Levy discovered. Although Levy said that comets do what they want, it might be more accurate to say that comets do what God wants.

Gravity Force and Life

Gravity Force and Life
Four fundamental forces impact our lives: electromagnetic force, strong and weak nuclear forces, and gravity force. We couldn’t live without them. More than that, we couldn’t live without them being exactly what they are and carefully balanced against each other.

Gravity is the weakest by far. For example, the strong nuclear force is 10 to the 38th power stronger than gravity. That is one followed by 38 zeroes. That strong nuclear force holds the nucleus of atoms together, but it acts over very short distances within the atom. The gravity force acts on larger objects over much greater distances.

If gravity were as strong as any of the other three forces, it would crush you and everything else as well! Because gravity is relatively weak, you can stand and walk. But it’s strong enough that you can also jump without flying off into space. Gravity holds our planet together. It also holds Earth in orbit around the Sun at the right distance to allow life to exist. Gravity keeps our Moon in orbit around Earth, and the Moon’s gravity stabilizes Earth’s rotation and causes the tides which clean our ocean shores.

Gravity is also a major force in our weather, causing air masses to move as their density changes. A stronger force of gravity would create strong and destructive winds. Gravity even makes plants grow upward no matter which direction you place the seed in the ground.

As matter moves around in the cosmos, it’s attracted to other matter by gravity. Gravity formed the stars and planets. Planets are spherical because gravity force pulls them into that shape. It is also the gravity force that pulls hydrogen molecules together to form stars. When the hydrogen molecules reach enough mass, the gravity force squeezes them tightly enough to cause nuclear fusion. The fusion of hydrogen atoms turns them into the essential heavier elements that make up planets and our bodies.

The gravity force is just right to make the universe, stars, planets, and life possible. If it had been slightly more or less, none of these things would exist. We think the precision of the forces of nature is not an accident, but the design of a wise God.

Cosmic Coincidence and the Heliosphere

Cosmic Coincidence and the Heliosphere
A cosmic coincidence took place on November 5, 2018. It had to do with our Sun and two probes that NASA sent into space.

To the average person, the solar system refers to our Sun and the eight (or nine) orbiting planets. However, between Mars and Jupiter there are asteroids and beyond the planets there dwarf planets and smaller bodies called planetesimals. So where is the edge of the solar system?

A bubble surrounds the solar system which scientists call the heliosphere. The Sun sends out charged plasma particles called the solar wind. Earth’s magnetic field protects us from most harmful effects of the solar wind, but we can see the effect of that “wind” as it ionizes molecules in the upper atmosphere creating the aurora we call the northern and southern lights. There is a limit to how far the solar wind reaches, and that is the outer edge of the heliosphere bubble. NASA’s Voyager 2 reached it on November 5.

Also on November 5, NASA’s Parker Solar Probe reached the inner edge of the heliosphere by flying toward the Sun. The fact that both probes arrived at the extreme boundaries of the heliosphere at the same time was not and could not be planned by the scientists at NASA. We would have to call it a cosmic coincidence.

NASA launched Voyager 2 forty-one years earlier in 1977. On its journey out of the solar system, it flew past and took pictures of all four gas giant planets (Jupiter, Saturn, Uranus, and Neptune). In late August of 2018, its plasma detectors, called Faraday cups, began to indicate that it was reaching the edge of the heliosphere. After 310 days of crossing that boundary, scientists determined that it passed out of the solar wind on November 5. Earth is about 93 million miles (150 million km ) from the Sun. Voyager 2 had reached 120 times Earth’s distance from the Sun.

Meanwhile, NASA launched the Parker Solar Probe on August 12, 2018, and it traveled toward the Sun. In three months it arrived at the Sun’s outer atmosphere called the corona. Parker’s job is to investigate how the solar wind originates. Scientists want to know how the Sun’s superheated atmosphere generates the solar wind plasma and blasts it into space at speeds of a million-plus miles per hour.

So, the cosmic coincidence is that two NASA probes launched 41 years apart arrived at almost the same time at the outer and inner limits of the heliosphere. Their mission is to give us new information about our solar system. Their arrival at the same time was a pure cosmic coincidence. The marvelous system they are investigating and that supports life on this planet is certainly not a coincidence. It shows the power and wisdom of the Creator.

National Guard and UFOs

National Guard and UFOs
During most of my military service, I was assigned to the 524th Batallion of the 38th Division of the National Guard in Bloomington, Indiana. Because I was a survey and recon specialist, I got to interact with men and women who were part of other battalions who told me about what was going on in their areas of service. Every summer we spent two weeks in summer camp doing military exercises. Since we were an artillery unit, we were always receiving new techniques and new materials. There were interesting stories related to the National Guard and UFOs.

The 38th Division of the National Guard spent their summer in camps in Grayling, Michigan and Camp McCoy, Wisconsin. Every summer we would hear about strange sightings near where we were drilling. People in these remote towns were not used to seeing Honest John Rockets fired high in the air. The flares we used gave sights that local people were unaccustomed to, but with small communities near the summer drills, not a lot of people were affected.

In 2017 however, there were more than 40 UFO sightings in and around Kokomo, Indiana. Bright lights were doing strange things, and even a string of lights sighted by several observers. On April 16, 2008, 911 dispatchers were inundated with 146 phone calls within a 15-minute time frame. That’s about 120 more than usual. Over 1000 people heard an incredibly loud explosion, and police started to search for a downed plane. This whole thing was reported on Discovery Channel’s “Investigation X” and History Channel’s “UFO Hunters.”

The National Guard has now revealed that the lights and sounds were from training exercises for National Guard aircraft stationed in Fort Wayne. The string of lights came from flares dropped several thousand feet above the ground. That is a technique used by jets to evade heat-seeking missiles. The sonic boom was just that, from jets training in the airspace known as Hilltop Military Operations Area. That area spans from West Lafayette to Logansport and includes parts of Howard and Tipton counties close to Kokomo and Bunker Hill Air Force Base just north of Kokomo.

There are several lessons here related to the National Guard and UFOs. One of them is NOT that there is no life in outer space. That question remains to be solved and has no biblical connections at all. What we do need to learn is that just because a story is on the Discovery channel or the History channel that does not automatically mean it is true. We need to remain open to new evidence and to how those discoveries relate to what the Bible actually says.
