Quasar Brighter Than 100 Billion Stars

It’s 2.5 billion light-years away, and brighter than the over 100 billion stars in our Milky Way Galaxy combined. If it were even as close as 30 light-years from us, it would appear as bright as the Sun, which is only eight light minutes away. Before anyone ever saw it, scientists detected it by the radio waves that it sends out.

In 1963, astronomer Allan Sandage was the first to observe quasar 3C 273 with a telescope. Quasars are the brightest objects in the known universe. They’re massive discs of particles that surround a supermassive black hole at the center of a galaxy. They emit intensely powerful energy as the black hole sucks the life out of matter and pulls it into its abyss. The energy is brighter than 100 billion stars.

The cloudy streak in the picture from NASA’s Hubble Wide Field and Planetary Camera 2 is a jet of energy that was fired off by the quasar at some time in the past. That streak is 200,000 light-years long! It would be impossible to survive in a galaxy with a quasar in its center. The intense energy from the quasar would destroy life while the black hole devoured the matter. We can be thankful that this quasar is so far away, even though it is one of the nearest.

Life on Earth is possible because we have no black holes or quasars near us. We think the universe reveals the work of an amazing Master Designer. We agree with Dr. Allan Sandage, the first person to observe a quasar, when he said, “Science makes explicit the quite incredible natural order, the interconnections at many levels between the laws of physics…Why is the design that we see everywhere so truly miraculous?… As I said before, the world is too complicated in all its parts and interconnections to be due to chance alone.”

Understanding Proteins and How They Are Made

How does insulin control blood sugar levels? How do antibodies fight coronaviruses? Questions like these have been at the frontier of biochemical research for as long as we have known there were such things as proteins. Understanding proteins and how they are made is a challenge that continues to be the focal point of a great deal of work.

The human body contains at least 20,000 different proteins, and their shapes are controlled by how their component amino acids are twisted and folded. In the medical field, the importance of understanding proteins is enormous. Not understanding proteins and how they are made would be like trying to fix a car engine when you don’t know how it works or how it was put together.

The Week for December 18, 2020, quotes Janet Thornton of the European Bioinformatics Institute, saying, “This is a problem that I was beginning to think would not be solved in my lifetime.” What has changed is that computers can do in hours what would take a human years to solve. Scientists have analyzed protein structures for malaria, sleeping sickness, and leishmaniasis (a disease caused by parasites) to find new methods of treating those diseases.

Amino acids are the basic building blocks of life, and we know that they exist in outer space and can be produced in the laboratory. Using these building blocks to make proteins that govern how life works is extremely complex. The amino acids bend and fold in origami-like structures to make proteins. To suggest that proteins can result from some chance process of organic evolution is stretching credibility to the breaking point.

Genesis gives us the simple statement, “And God said ‘It is good.’” As biochemistry begins understanding proteins and how they are made, we see how complex God’s creation is. Those simple words wonderfully describe what we are starting to understanding as a work of incredible intelligence and design.

Planetary Conjunction for the Winter Solstice

If you have looked to the southwest just after sunset in the past month, you probably saw two bright stars that have been moving closer to each other. They are not stars. They are the planets Jupiter and Saturn, two of the brightest objects in the sky, reaching a planetary conjunction for the winter solstice.

In their orbits around the Sun, Jupiter and Saturn appear to pass each other about every 20 years. However, the last time they appeared this close was in 1623, just 13 years after Galileo first pointed his telescope into the night sky and discovered four moons of Jupiter and saw Saturn’s rings. On December 21, those two planets will appear only one-tenth of a degree apart. That is one-fifth the diameter of the full moon.

You can bet that there will be hucksters making connections between this very unusual astronomical event and the star of Bethlehem or various political events. This conjunction is not part of a doomsday scenario but a demonstration of the accuracy of scientific observation. We can predict planetary conjunctions or solar and lunar eclipses to the minute, which is not hard to do.

When I taught earth science using the Earth Science Curriculum Project, we did a lab where the students predicted an eclipse of the Sun. They predicted when it would begin, when it would reach totality, and when it would end. I tried to make this a school-wide event, and the principal permitted me to take all 1000 students onto the school lawn to witness the eclipse. We gave the students special glasses and set up our telescopes to observe the eclipse.

We told the students what was going to happen and when it would happen. When it started, and the sky got dark, dogs began to howl. Crescents appeared on the ground under the trees as the eclipse projected through spaces in the leaves. Even though we had told the students what would happen, some kids began crying and ran back into the building in fear.

Why do people lack trust in scientific information, whether it concerns an eclipse, planetary movements, climate change, or COVID-19? Science and the Bible are friends, and God has called us to look at the creation around us and learn from it. Proverbs 8, Romans 1:19-20, and Matthew 6:25-33 all remind us of science and faith’s symbiotic relationship.

Tomorrow we will consider this planetary conjunction and the star of Bethlehem.

Life Requires Polar Molecules

Chemistry is a fascinating science. The design of atoms and molecules allows life to exist. Science fiction writers have tried to convince us that there could be life out in space that is radically different from life on Earth. The subject of this discussion is not whether there is life on other planets or moons. If God created it, then it will be there, and we will find it. But life requires polar molecules.

Skeptics have maintained that to be open-minded about life in space, we must look for life based on something other than the CHNOPS. (CHNOPS is carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur.) Why not life based on silicon, iridium, cesium, iron, and chlorine?

A basic biology principle that most of us learned in high school is that to exist, life requires polar molecules. That means there has to be an abundance of a molecule with a positive and a negative end. On our planet, the molecule that meets that requirement is water.

The oxygen molecule is designed so that when it combines with two hydrogen atoms, it forms a water molecule that has a positive and a negative end. This design enables water to do a variety of things necessary for life. Water moves things around, dissolves other compounds, conveys nutrients into cells, and carries away waste. Other polar molecules, like amino acids, proteins, or DNA, could not be manipulated and used without water. Life requires polar molecules.

Astronomers have discovered methane and ethane on planets and moons throughout space, but they cannot support life because they are not polar. The media have brought attention to the moons Titan and Europa, which both seem to have oceans and rivers of methane and ethane. Other moons such as Enceladus, Ceres, Ganymede, Callisto, Dione, and Triton are chemically active and have some water, but they are dominated by non-polar chemicals. Chemical studies of the 4000 plus exoplanets astronomers have discovered do not show any other polar molecules in abundance.

Life has to follow some basic rules. One of those rules requires polar molecules in abundance for any kind of life to exist. An oxygen atom has eight electrons, but its structure allows only four electrons in its outer orbit. That is important because the outermost orbit is the only one that allows other elements to share electrons to make a compound. The four inner-orbit electrons with their negative charge cannot be shared. That automatically means that the oxygen side of any compound, such as water, will be negative, and the other side will be positive. This principle is the starting point for biochemistry, and it is a design invented by an Intelligence that established the rules for life.

When my students saw this in basic chemistry, there was always someone who would say, “Wow! Who thought that up?” As a public high school teacher, I was not allowed to say “God,” but the message is clear without being said.

For more on this, see the article titled “Looking for Life in the Universe” by Dr. Morgan Cable in the January 2021 issue of Astronomy magazine (page 46-48). Dr. Cable is the supervisor of the Astrobiology and Ocean Worlds Group at the NASA Jet Propulsion Laboratory. Her research is about looking for life and habitability in space

Architect-Engineer, Magician, or Chance

One of the things that John Clayton often emphasizes is that God is an architect-engineer. Some people see God as a magician. As John likes to say, they see God “zapping” things into existence. So which is correct— architect-engineer, magician, or chance?

If we think of God as a magician, we are rejecting science. We are like the ancients who saw magic in lightning, volcanoes, wind, fire, and everything else. They saw magic in the created things, and they worshipped the creation. So they had a god of the volcano, a god of the river, a god of the harvest, and on and on.

Science today has told us what causes volcanoes and hurricanes, so we no longer see them as gods. Science tells us how stars begin and how they die. It tells us how the elements are formed within stars. Science also tells us how our solar system developed. Plate tectonics reveals the processes that gave us today’s continents, and scientists are studying the formation of our atmosphere. We see how millions of things came together to provide us with a habitable planet. Were all of those merely fortunate accidents, or were they intelligently designed? Remember, the alternatives are architect/engineer, magician, or chance.

The greatest mystery of all is how non-living elements became life. How did those elements come together to form amino acids, proteins, RNA, DNA, and living cells? We are still far from understanding that, but it is evident that the chance of it happening without a guiding intelligence is vanishingly small.

However, once that life threshold has been crossed, the accepted faith in the science community is that evolution took over from there. The accepted science dogma today is the worship of evolution. That dogma says naturalistic evolution is the god that developed all forms of life, including ourselves. For a scientist to deny that dogma is to commit heresy. Any scientist who wants to keep his or her job, credentials, prestige, or credibility must adhere to the dogma and worship the god Evolution. It all happened by natural selection acting on random mutations, and you better believe it, or at least pretend you do.

But, is chance a viable explanation? Does our everyday experience of designed things, from shovels and lawnmowers to cars and computers, tells us anything? It should say to us that those things don’t design themselves. It should be evident that intelligence, not mere chance, was involved in all of them.

Again, the alternatives are architect-engineer, magician, or chance. If we rule out chance, that leaves us with two options. If God is a magician who “zapped” everything into existence and made it look old, the study of science becomes futile. Why would God try to fool us into thinking we can study the ancient creation processes when there is no such thing?

If God is an architect-engineer, we can study the creation and see how He worked to design and engineer the universe, our solar system, our planet, and even life. We don’t see those creations as gods. Instead, we see the God who created them, and we worship Him. The bottom line is that we see evidence of God in the things He has made (Romans 1:20).

Mighty Mouse Drug May Help Space Travel

One of the problems with space travel is that the human body was designed to live on Earth. When people are in weightlessness for an extended time, they lose muscle and bone mass. This loss can be as much as 20%. A possible solution might be called the “mighty mouse drug.”

Dr. Se-Jin Lee of the Jackson Laboratory at the University of Connecticut has published findings of a drug that blocks a pair of proteins that typically limit muscle mass. When scientists treated mice with this drug, they maintained their weight and muscle mass even when they were in the International Space Station for a month.

The application of this research can do more than provide a way for humans to survive a trip to Mars. It may also benefit people who are confined to a bed or a wheelchair.

This research reminds us that God designed our bodies to function in Earth’s gravity, just as He designed Earth to support life. Problems occur when we subject our physical bodies to forces they were not designed for. These problems require extreme solutions, and God has given us the ability to use science to find solutions such as the mighty mouse drug.

Did Science Find Life on Venus?

The media loves to jump on any sensational scientific finding, even if their headlines totally misrepresent what science has discovered. We have seen several headlines suggesting that scientists have found life in the atmosphere of Venus. Did science find life on Venus?

The fact is that a Japanese robotic satellite that has been orbiting Venus since 2015 records data in the ultraviolet part of the spectrum. The satellite has detected spectra for the chemical phosphine (PH3). Phosphine is a flammable, toxic gas made of one phosphorous atom attached to three hydrogen atoms. It is difficult to make in a typical chemistry lab. Biologists know that there are microbes that can make phosphine. Finding the chemical in the upper clouds of Venus, where the temperatures are low enough for the gas to exist, raised some questions about whether microbes could have produced it.

It is possible that the phosphine could have been produced by conditions on Venus that are not available on Earth. Such conditions could be very low pressures, long term effects of ultraviolet light, and long periods of time. The environment of Venus is highly toxic, even to microbes, so microbe production is unlikely. Scientists have found many of the chemicals essential to life or possibly produced by living organisms on several moons in the solar system. The creation process produces chemicals that can be associated with life, including water. The environmental parameters of all of these places are so extreme that no astronomer expects to see an alien walking around.

The Bible doesn’t say that Earth is the only place where life exists, and it may be that God has created life elsewhere. As humans leave our planet searching for chemicals and materials to meet the 21st century’s needs, we may find a storehouse of essential materials, both metallic and biological. Did science find life on Venus? No. This newest media hype does not tell us anything we didn’t already know, but the discovery is interesting.

Nepenthes or Pitcher Plants

One of the most interesting studies in botany is the study of plants that live in areas with little or no soil nutrients. Scientists give them the genus name Nepenthes. We commonly call them pitcher plants and they grow all around the Earth. These plants get their nitrogen and phosphorous by eating insects and animals. Darwin called them part of the “carnivorous syndrome.”

Most people don’t realize that there are well over 100 species of pitcher plants. Each species has some unique features, but there are many things they all have in common. All pitcher plants have a cup which is funnel-shaped or tubular with a sticky digestive fluid inside. The top of the tube has a rim called the peristome which is slippery and causes prey to tumble into the cup. There is a shelter over the top of the pitcher to keep out rainwater which would dilute the digestive juices.

There are highly specialized pitcher plants that eat different things. In 2009, botanists in the Philippines found plants that were nearly five feet (1.5 m) tall and had cups that were roughly a foot (.3 m) in diameter. In Borneo there are pitcher plants that can hold three quarts of liquid and trap lizards, mice, and other small rodents. One species secretes sugary nectar on the lid with a perch that attracts mountain tree shrews. The plant doesn’t eat the shrews, but as the shrew sits on the perch eating the nectar, the pitcher servies as what one study called a “tree shrew lavatory.” The shrew’s droppings provide nitrogen-rich food for the plant.

There are many areas where soils are deficient in nitrogen and phosphorous, but for different reasons and in different amounts. Insects provide the missing nutrients for most Nepenthes in North America. The needs in a desert salt flat are very different from the needs in a tropical rain forest. It is quite a challenge to explain how the diversity that we see has come about by evolution. Furthermore, scientists cannot find an intermediate species, either fossil or living, to explain how Nepenthes developed by evolution. We see a common plan design with local adaptations allowing plants to thrive in environments that lack the essential nutrients for them to prosper.

Nepenthes are so unique that people sometimes collect them for house plants. They are a reminder that God has provided well-designed plants and animals for unique locations. The study of the Nepenthes genus teaches us how special needs for life are met by the intelligence of God as plants and animals reflect God’s wisdom.

Mystery of Cicada Wings and Raindrops

We often see an animal or plant with remarkable abilities or properties that are not obvious how they work. One of those is the mystery of cicada wings and raindrops.

Scientists studying cicadas have noticed that their wings repel water and have antimicrobial properties. Every past attempt to understand how this works has destroyed the wing before finding the answer. However, it did appear that there were layers to the wing.

Scientific American (September 2020, page 21) describes a new method of analysis called microwave-assisted extraction. Using that method on cicada wings, scientists at Sandia National Laboratories peeled back the outer layer revealing a fantastic design.

Under the outer chemical layers, cicada wings have structures called nanopillars. When scientists removed the nanopillars’ chemical layers, they became shorter and bent towards each other, making the wing structure so close that water could not penetrate it. The chemical layers on top of the nanopillars kill microbes.

Marianne Alleyne, an entomology professor at the University of Illinois Urbana-Champaign, was the study’s senior author. She said this knowledge will help scientists understand how to use chemicals and structure to engineer new products. “We can design new materials more rationally, making choices about the structure and chemistry based on what we have observed in nature,” Alleyne said. This is one more example of how science can copy nature to give us new products.

Romans 1:20 tells us that we can know there is a God through the things He has made. The mystery of cicada wings and raindrops is another example to verify that statement and show us ways to improve our lives here on Earth.

Magnetotactic Bacteria Finding Their Way

Before GPS, people found their way with a compass. Many still do. Did you know that finding your way is possible, even if you don’t have any eyes or ears, or even a brain, as long as you have a compass? Magnetotactic bacteria (MTB) use the magnetic field of planet Earth to know which way to go. To do that, they have to build a compass. Realize that these are single-cell organisms that live in marine or freshwater habitats.

Inside the cells of all living things, there are subunits called organelles that perform various functions. MTB have organelles called magnetosomes that contain magnetic crystals. They build the magnetosomes by digesting iron and combining the iron with sulfur to form iron sulfide or with oxygen to form iron oxide. The iron oxide is also known as magnetite, and it’s a powerful magnet.

The bacteria form chains of these magnetic crystals inside their cells. The magnetosome chain acts as a compass needle aligning the MTB to Earth’s magnetic field. In this way, the magnetotactic bacteria can “know” the direction to move. Why do these bacteria need to know directions? They are anaerobic bacteria, meaning that they survive without oxygen. Oxygen can be deadly to them, so they need to find an area away from it. Rather than blindly going around in circles looking for a safe place, they move in a straight line to their anaerobic safe zone.

In 1963, an Italian scientist first noticed certain bacteria aligning and moving in the direction of the north pole. It wasn’t until 2007 that scientists paid much attention to that observation. Without eyes, ears, or a brain, magnetotactic bacteria can find where they need to go. But without a brain, how can they know to do this? And how can a single-cell bacterium build the magnetosome organelles? These magnetic crystals are difficult for humans to create in a laboratory. In fact, scientists have found that the magnetite produced by bacteria is better for some applications than what the scientists can produce in the laboratory. For that reason, they are looking to find a way to mass-produce MTB to obtain their magnetosomes.

Who taught the magnetotactic bacteria this fantastic skill? Did one of them figure it out and then pass that knowledge on to future generations? We don’t think so. A better explanation is that the Master Designer programmed the skill into them.

You can read a scientific paper on MTB at THIS LINK. Leading evolutionary biologist J.B.S. Haldane (1892-1964) once said that if you could find a magnetic mechanism as part of a living organism, it would disprove evolution. You can read more about Haldane and his statement at THIS LINK.
