Genesis 1:14-19, “And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. And God set them in the firmament of the heaven to give light upon the earth, And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good. And the evening and the morning were the fourth day.”
I absolutely love astronomy! For the past couple years I've been watching YouTube documentaries about the universe, which have sparked my curiosity into the subject. The more that I learn the more intrigued I become, fascinated by God's amazing universe. Psalms 145:3, “Great is the LORD, and greatly to be praised; and his greatness is unsearchable.” Our faithful omnipotent God is more than amazing!!!
Did you know that NASA says there are approximately one septillion stars? That's a 1 with 24 zeroes behind it! Yikes! And yet of those one septillion stars, mankind will only ever be able to physically visit one of them, our own Sun (which is 93 million miles away). The next nearest star Alpha Centauri is 4.24 light years away (25 trillion miles). Even if one of our fastest space probes travelling at 40,000 mph were to attempt the journey from Earth to Alpha Centauri, it would take 625 million years! So you see, man will never visit any star except our own Sun.
Astronomy is one of my hobbies, which I am getting more heavily into lately. I can't get enough of it. Every night as I sleep, I listen to the Calm Space or Sleepy Science YouTube channels. The man's voice from Calm Space (in the Netherlands) is very calming and I love learning facts about God's wondrous universe. The man's voice is also relaxing on the Sleepy Science (in the United Kingdom) channel. I encourage you to listen to these channels at night. I keep the volume just high enough so that I can understand what is being said, but not so loud that it wakes me up. Setting the volume at the proper level is important. The videos are each 2 hours long, intended to help you sleep. I love this stuff!
Helpful Tools For The Hobbyist Astronomer
I recently learned about some really awesome apps for mobile phones:
- Sky View (SkyView® is an app that lets you identify and learn about celestial objects in the sky, day or night. You can use your camera, schedule alerts, time travel, and share your discoveries with friends and family. I paid a one time fee of $4.99 to enable the full version, which lets you see all the full color constellations and thousands more stars)
- Star Tracker (Pretty much the same function as Sky View, but different controls. Get outdoors with your friends and enjoy star gazing! Let StarTracker guide you to explore the universe. I paid two fees: $0.99 and $2.99 to enable the full version)
- NASA (Launch into the joy and wonder of space exploration with the NASA app! Stream live mission coverage on NASA+, see the latest images from the moon and beyond, and so much more.)
- International Space Station (The Spot the Station mobile app is designed to notify users when the International Space Station (ISS) is visible overhead from their location.)
- Stellarium Mobile (Stellarium - Star Map is a planetarium app that shows exactly what you see when you look up at the stars.)
It was the 4th of July yesterday. I couldn't sleep, so I was outside this morning in my backyard using Sky View and Star Tracker. I love these tools! The GPS technology inside your phone allows the apps to locate and display where stars, planets, meteorites, the International Space Station and other astronomical things are found. It's amazing technology!
The Amazing Planet Venus
You can even use the apps inside your home. If you want to know where Saturn is, the app will show you. I've been watching the bright planet Venus all week in the evening sky from West Pensacola where I live. For the month of July, the planet Venus is called the “Evening Star” in the western sunset, and the Morning Star at sunrise in the east. Since Venus orbits closer to the Sun than Earth does, it is usually found close to the sun in the sky.
Venus is a remarkable planet, with an average surface temperature of 867° Fahrenheit, and an atmospheric pressure of 1,350 psi. Earth's pressure is 14.7 psi at sea level. Venus rotates at a speed of about 4 mph, which is slow compared to other planets in the solar system. Whereas the Earth turns on its axis once every 24 hours, Venus has a rotational period of 243 days, making one day on Venus longer than a year on Venus (which is 225 days). That is so weird!
It is my humble opinion that God made all these remarkable planets, stars, nebulas, black holes, galaxies, supernovas, dark matter and endless wonders of the universe to impress us as his creatures, who were all made in His image.
For under $100 you can purchase a decent pair of 15 x 70 Astronomy Binoculars to observe the stars. If you already have a tripod for a video camera, these binoculars will fit on the same tripod (they're all standardized). You need a tripod because the glass get heavy over time. It has never been easier to study, be fascinated by and follow the sky. God is more than amazing!
Astronomers are unsure if the cosmos keeps going infinitely, or if the universe has an end to it. Based on the following Scripture passage, I think the universe has an end to it. Psalms 147:4, “He telleth the number of the stars; he calleth them all by their names.” If God telleth the number of stars, it sounds like there's an exact number, which would indicate that the universe does end. God not only knows how many stars there are, but He calls them all by their individual names. Wow! NASA guesses there are at least one septillion stars! I cannot even wrap my brain around that gargantuan number because it is so big. Let me write it out, so you can see how many stars there are in the known universe...
1,000,000,000,000,000,000,000,000 stars!
Just to count to one trillion (if you could count one number per second non-stop) it would take 31,700 years. Then there's quadrillion, quintillion, sextillion and septillion. These numbers are so large that the human mind cannot process them. And yet, our omnipotent God who spoke them into existence by the mere power of His Word has a personalized name for each star.
Before 1924, astronomers all thought the Milky Way Galaxy was the universe. It wasn't until 1924 that astronomer Edwin Hubble (1889-1953), discovered that there were other galaxies far beyond our own Milky Way Galaxy. Dr. Hubble discovered that the Andromeda Galaxy is located 2,480,000 light years from the Earth.
Then in 1929, Dr. Hubble discovered that the universe is expanding, which discovery led to the theory commonly known as The Big Bang. Scientists worked backwards and calculated that the universe must be 13.77 billion years old. But since the universe has continued to rapidly expand during that time, astronomers are able to peer 46.5 billion light years into the cosmos.
When I was a kid, I used to walk up the stairs on a moving escalator, which made me feel like I was moving super fast (and I was). Although my feet were stepping up the stairs at a normal pace, I was moving much faster since the escalator was also carrying me up to the next level. That's similar to what has been happening to the cosmos for the past 13.8 billion years.
Although no object can travel faster than the speed of light (671 million mph), space itself can. That is an amazing reality and concept. So, during the past 13.8 billion years (a measurement of time), the cosmos has expanded 46.5 billion light years (a measurement of distance). This is why astronomers will never be able to see beyond 46.5 billion light years into the cosmos, because the light being produced now is too far away to catch up. Literally, the cosmos is expanding faster than the speed of light, so that light will never reach earth's telescopes.
It is my humble belief that the universe ends just beyond the point where man cannot see further. What would be the point? And remember, God “telleth the number of the stars; he calleth them all by their names” (Psalms 147:4). If you'd like to just try it out, you can freely download limited versions of Sky View and Star Tracker for free. My favorite though is Star Tracker. It only cost $3.97 total for enable the full version. First I paid $0.99, and then there was a $2.99 charge. I'm not sure what the $0.99 was for, I cannot remember. There are no monthly charges, which was the first thing I checked to make sure. I hate monthly payments.
If you have any interest in astronomy, even if to just follow the moon and some of the brightest stars, I think you'll enjoy the Star Tracker app. I turned on the grid lines in the app, which centers around the bright Northern Star, Polaris. I like the background planetarium music. It's an amazing tool. I just wanted to share something that I enjoy with everyone. I love this stuff! God is so good. Proverbs 18:1, “Through desire a man, having separated himself, seeketh and intermeddleth with all wisdom.”
