For a few years ago an astronomy friend of mine and myself went out to our favorite location where we normally setup our telescopes and did our stargazing and astrophotography. On a late evening we had two journalists joining us (Johan Joelsson & Jonatan Jacobson) to do an interview based on a research my friend had been working for years, namely, charting how extensively light pollution had spread across in south and the central regions of Sweden. At the time there was no agency, or other independent organizations that had any detailed maps over this. My friend’s idea was to assist amateur astronomers but also provide awareness over this issue.
Light pollution can be typically described as the unawareness of the effects on how we use light sources at public, our buildings, our farms and other types of facilities/buildings and the consequences it brings towards the environment and the ecosystem overall.
Light pollution in our environment can be easily discarded as nonsense but when satellite imagery started to become publicly accessible, it was hard to ignore it. The expansion of cities over the decades, the deforestation, the new road systems with lights spreading across countries and the ever increased human population start paying its toll towards the environment (Below is a satellite image over US, showing us how extensive light pollution is across the east part of the country).
What many people are unaware of (other than the term itself) is that it has an immense impact to human life and wildlife. Wild animals that are using darkness to hide from nightly predators, or predators who use darkness to be camouflaged or to see better, or even newborn turtles are mislead starting to wander towards cities instead, are just a few out of many examples where the pollution got out of hand.
To us astronomers just like wildlife itself, are trying to seek ourselves away to darker areas, as far as possible from civilization in order to be able to observe the wonders of the night sky. Professional astronomers that work with research are trying to build new facilities in remote areas as well, such as the top large mountains or inhabitant areas in other continents.
Apart from that, there’s also on-going studies to determine how badly flora is effected when it comes to cellular respiration and growth. And not so surprisingly when it comes to humans there are already two types of cancer connected to this issue, as well as the disturbed production of melatonin in our bodies. In recent years there has been an increased amount of prescribed melatonin by doctors around the world to their patients. Melatonin is the substance produced by our brains to help balance our sleep cycles.
Below is an illustration from the software Stellarium that got a setting to turn on different levels of light pollution on your night sky. Stellarium can even extract data from your area you live at and apply the appropriate level of light pollution automatically for you. From left to right you have light pollution level 1 (national parks, or far away from civilization), level 3 in rural areas (country side, with few farms and some forests), level 5 (minor cities with a population of 1000 to 5000 people), level 7 (suburban areas with a population of 10,000 to 100,000 people) and finally level 9 are large cities where only main constellation stars, planets are making barely any appearance in the skies in ideal city conditions (without smog, fog, smoke, etc.)
All in all, the severity of the effects from light pollution can be easily classified as an equal to other environmental pollution. We loose our night skies resulting to younger generations having no memory of describing something as easily identifiable as the milky way. Some humans haven’t seen anything else apart from the moon and sun. Their knowledge is based on images from google, school books and because the teacher said so.
The night sky was once upon a time a source of inspiration from the ages of antiquity to recent years, but it is constantly under daily threat. Would humanity ever experience night-sky-inspired individuals such as Galileo, Newton or Einstein if the skies don’t look the same anymore? For those who’ve been reading on their biographies will realize that they were inspired by the freedom of thought and the wonders of cosmos.
There is still however hope as long as we get aware of what all this means and if all of us take a few moments to take our own little measurements that will add up. Get new light bulbs for your backyard that point downwards and don’t reflect or spread light more than what is necessary and even visit the International Dark Sky Association to read more in regards to light pollution and how you can help to educate others about it and to become the advocates of it.
Our environment is in need of more awareness from all of us, much more now than ever before. You can save energy and lower your energy bills at your own home by turning off unnecessary light sources, install light sources pointing down to the areas you’re interested instead of letting your light sources scatter light in your surroundings and the sky (unnecessary loss of energy for no purpose). If you live near the beach, harbor, sea in general, avoid pointing light sources towards the waters or forests. That may save the life for animals.
Once a year is the celebration of Earth Hour. Turn off your lights for just 1 hour to save energy and to teach your younglings about the environment which we are part of.

Right after solar eclipses it is commonly expected to observe a total lunar eclipse. In California we’ll be able to observe a total lunar eclipse on January 31, 2018 starting at 02:51 AM.
As the moon moves the first type of shadow will be the earth’s penumbra and as it finally reaches totality it will turn full red (umbra).
The examples I’m posting here, are some very old afocal photos I took when I was living in Stockholm, Sweden through a Newton telescope. These were my very first images back in August 16, 2008 and little I knew about focus, exposures, etc. That will make it easier for me to redeem myself with proper equipment and methods.
Below is how the total lunar eclipse shadow will move across the continents on January 31, 2018. This illustration originates from timeanddate.com. Visit this website to find out how your own eclipse will look like at your location and which time.
Here’s an image from the free license software – Stellarium, showing how the lunar eclipse will look at from your location. Stellarium can be downloaded at no cost for all platforms (Mac, Linux and Windows) click here to download Stellarium.
This is the first portion of photos me and my wife took during the American Solar Eclipse, August 21st, 2017 at Corvallis in Oregon. I’ll keep posting more photos as time goes and as I find more time in order to process them from their original format in my cameras.
Here are some of the total solar eclipse photos. To the left is the diamond ring while on the right is the totality. Note a couple of prominences (fire flares) showing in the edges of the sun on the top but also the moon’s surface doesn’t appear to be perfect round because of the mountains and valleys in its surface.
We met many interesting and friendly people from Kenya (the country), Phoenix Arizona, San Fransisco bay area, Arkansas, Texas and other cities in California. If you guys read this please comment or send me an email with your names so I can add you here!
Among all of them we also had Jodie Smalley coming up to us, asking if we could take some photos while she breathed fire during the totality of the eclipse. My wife went off with her at a place without grass to record that awesome idea she had (watch the fire breathing video below were Melissa talks also about the shadows on the ground).
Below you’ll find some of our videos and photos while we were preparing to start documenting this amazing event!
To my surprise Youtube has stopped offering the ability to add annotations in your videos anymore, as mobile devices don’t support them. Annoying as you can’t add corrections or additional comments to the narrative sound in the background. But according to Google 60% of the users are using mobile devices to watch these videos, which is quite remarkable. However, just before the eclipse I shouted “ring of fire” which is the wrong technical term. Obviously, I meant to say “diamond ring” instead.
A ring of fire is the maximum of an annular eclipse. Now, annular eclipses are the ones when the moon is further away from the earth hence it doesn’t cover the entire sun. An annular eclipse is around the corner and will happen October 14, 2023 and you can see it from northern California.
After the 2023 annular eclipse and If you’ve also missed the 2017 total eclipse, there’s one more chance in 2024 in Texas.
Here are some photos from my friend and colleague Akash Garg who was in Sacramento, California at our work area. Even though the eclipse was partial in Sacramento, he could still see the crescent-shaped shadows on the ground from trees and other objects.
Melissa and I will be observing the solar eclipse from Corvallis. Thanks to the Corvallis Sheriff’s department we found a new location to camp, avoiding to relocate on the day of the event, allowing us also to avoid traffic and early morning stress! Big thanks goes to all my friends that helped out.
While browsing through Youtube, I stumbled on a video by the College of Arts, Letters and Sciences in regards to observing the solar eclipse. Very useful info and insight on how solar eclipse works in general.

I wrote on my previous blogpost about the Solar System Scope by INOVE. This time I thought I’d write some extra about it. Beside their awesome interactive website, INOVE has developed their solar system to be accessible from Android devices. If you enter the App Store make a simple search for “Solar System Scope” and you’ll find it available for free.
It is the perfect app to teach yourself and others (your kids, or at the school) about our solar system. These days you can connect a mobile device to your laptop to enable projection on big screens.
Solar System Scope has some basic data about each object that is part of our solar system. From planets to dwarf planets, moons, comets, asteroids, constellations as you browse among many of them enabling you to explore their orbits, behavior and most importantly fast forward or rewind to observe their positions at a certain point in time.
Another cool feature is that you can “open up” planets to look at their interior and see what they consist of. Above you have two examples from the planets Saturn and Mars respectively. I believe this app is the coolest so far when it comes to graphics and usability. It is a very user friendly and intuitive app that has a simple design making it possible start using its advanced features within seconds.
I really hope INOVE takes this app one step further and offers us to explore other neighbor solar systems that we know off in scientific ways. How cool wouldn’t that be?
Unfortunately this app is only available for Android devices. I was hoping one day they’ll make a release for Windows mobile devices as well.
So there’s this thing going around that California will suffer great disaster. All that according to one of Nostradamus prophecies. Let us have a closer look to what he wrote:
The trembling so hard in the month of May,
Saturn, Capricorn, Jupiter, Mercury in Taurus:
Venus also, Cancer, Mars, in Virgo,
Hail will fall larger than an egg.
Upon closer look let us sort the planets by constellations:
- Constellation Capricorn:
– Planet Saturn (Exists instead by the constellation of Libra)
- Constellation Taurus:
– Planet Jupiter (Exists instead by the constellation of Cancer)
– Planet Mercury (The only one that matches the prophecy)
– Planet Venus (Exists instead by the constellation of Gemini)
- Constellation Virgo:
– Planet Mars (Exists instead by the constellation of Taurus)
So nothing matches except of the planet Mercury. The 29th of May 2015 looks pretty safe to me, so enjoy your weekend everyone! No need to barricade in your shelters or buy any food supplies.

Every single thing you can sense around you is made of matter. Every single atom in your body, was once forged inside the nucleus of a star for a very long time ago, even before our solar system existed.
We are products of star fusion, supernovas. But recently astronomers discovered in simulations, we might also be parts of even more rare events of collision of stars, which explains the rarity of heavy elements such as gold, platinum, uranium and so on.
This rarity is what makes gold so precious to humans and used throughout history as currency. Something that not everyone possess or is able to acquire in large quantities. The reason to that?
First you need a binary system… Not like our own solar system, but a system with 2 stars orbiting around each other. That’s is not extremely common either. But also in this recipe we need these stars end up as neutron stars at the end of their lives and finally a dramatic end…. A collision between them.
Now that is more of a rare event.
Although this might sound almost like impossible, the vast amount of space and the tremendous amount of star systems created over time in a galaxy, results mathematically having these events not to be as rare as we thought. To a human being, 100 years is experienced as a very long time. In astronomy on the other hand, you’ve got ridiculous huge numbers of distances, time span and forces. Something that the human mind cannot comprehend pure mathematically… It is not as far as the neighbor house around the corner, or your monthly salary, or the age of your children, or the number of pages of your favorite book. We talk about billions of years, or distance of the speed of light covered over thousands of years away, and so on.
And like Carl Sagan said… The amount of stars in our galaxy are much more than the amount of sand grains from all beaches on earth put together.
The fore the human body need some of these rare elements in order to function. Remember that stars can fuse only as heavy elements as iron (Fe), heavier than that and you’ll need even stronger and violent forces. Ones that would be expected by the death of stars or by colissions. And some of these elements are made by supernovas and now even believed by neutron star collisions.
So, if you consider proposing to the one you love and give her a ring, then explain to her. “My love, this ring is rare and unique. So unique, that two neutron stars had to collide for it to exist and now finally be placed on your finger”. I’m sure you will make her feel special, as much as that neutron star collision.
The theoretical predictions got now to be put in practice and observed by astronomers.
