Understanding Light Pollution in Borrego Springs: A Dark Sky Community
Share
Light pollution is excessive or misdirected artificial light that can interfere with the visibility of the night sky. It is a growing concern in many areas, including Borrego Springs, which is designated as a Dark Sky Community by the (IDA).
Light pollution can have negative impacts on the local ecosystem, including disrupting the migration and reproduction patterns of certain species and making it difficult for astronomers to observe the stars. It can also affect human health, as exposure to artificial light at night can disrupt sleep patterns and lead to a range of health problems.
To address the issue of light pollution, the IDA works with communities to promote the use of lighting that is designed to minimize light pollution. This includes encouraging the use of dark sky lighting products, which are designed to direct light downward and reduce the amount of light that escapes into the sky.
By using dark sky lighting products and taking other steps to reduce light pollution, communities like Borrego Springs can help to protect the night sky and preserve the natural beauty of the area for future generations.
The Benefits of Living in a Dark Sky Community
There are several benefits to living in a Dark Sky Community, such as Borrego Springs, which has been designated as a Dark Sky Community by the International Dark-Sky Association (IDA). Some of these benefits include:
- Preserving the natural beauty of the night sky: One of the primary benefits of living in a Dark Sky Community is the opportunity to experience the beauty of the night sky free from light pollution. This can be especially important for stargazers and astronomers, who rely on a clear view of the stars for their work.
- Protecting the local ecosystem: Light pollution can have negative impacts on the local ecosystem, disrupting the migration and reproduction patterns of certain species. By reducing light pollution, Dark Sky Communities can help to protect local flora and fauna.
- Promoting human health: Exposure to artificial light at night can disrupt sleep patterns and lead to a range of health problems. By reducing light pollution, Dark Sky Communities can help to promote better sleep and overall health for their residents.
- Enhancing tourism: Dark Sky Communities can be attractive destinations for tourists interested in stargazing and experiencing the beauty of the night sky. This can provide economic benefits for the community through tourism-related businesses and activities.
Overall, living in a Dark Sky Community can provide a range of benefits, including the opportunity to experience the beauty of the night sky, protect the local ecosystem, promote human health, and enhance tourism.

By Dennis Mammana Week of Aug 16-22, 2026 It was 20 years ago that our solar system lost a planet. Well, it didn't really go anywhere, but Pluto is no longer a planet because it's been reclassified. I'm sure you figured out in school that scientists love to classify things. Rocks, clouds, plants and, yes, even stars and planets. So why did they feel the need to reclassify Pluto? Because Pluto doesn't seem to fit the pattern of the rest of the major worlds of our solar system. First, it's a world not even 1,500 miles across; in other words, if we could bring it to Earth, it would fit inside of Mexico. Its orbit is tipped about 17 degrees to the orbits of all the other planets and is so elongated that every 240 years it crosses the orbit of Neptune. In addition, Pluto is an icy world with only five known moons, yet it exists in the realm of the gassy, ringed giants, around which hundreds of moons orbit. This is one strange world, so on Aug. 24, 2006, when the International Astronomical Union reclassified it as a "dwarf planet" — one of five currently known — some folks became quite upset. I hear people say all the time, "Pluto was a planet when I was in school, and by God, it's still a planet!" But that's not how science works. As we learn more about nature, we find characteristics and patterns that don't match up with our previous notions. Sometimes when that happens, we must change the way we think. It's all good science, and it happens more frequently than you might imagine. Ages ago, anyone on the high seas would have considered whales as fish. Though whales were known to have characteristics different from fish, it wasn't until 1758 that the 10th edition of Carl Linnaeus' "System Naturae" officially branded them as mammals. I'd be willing to bet that if the internet had existed back then, folks would have been screaming for Linnaeus' hide, and proclaiming, "Whales were fish when I went to school, and by God, they're still fish!" But here we are, three centuries later, and no one's upset any longer. No, Pluto just doesn't fit the patterns of all the other planets, so for that reason, it seems to me, Pluto cannot legitimately be categorized as a planet. So if Pluto's not a planet, what is it? A moon of one of the outer planets that broke free? A monster comet? A weird missing link? Good questions, all. Unfortunately, we just don't know. It was in 1930 that Clyde Tombaugh found Pluto, and some of his ashes were carried onboard the New Horizons spacecraft as it sped past and explored this distant world in 2015. Those who are more sentimental than scientific believe that this reclassification is an insult to the man who was so very proud of being the discoverer of the last planet of our solar system. I knew Clyde, and I'm pretty sure this wouldn't bother him one bit. In fact, I suspect he would be even more honored to be the discoverer of the first of an entirely new class of worlds!

The Perseid meteor shower is expected to peak during the predawn hours of Thursday, Aug. 13.
By Dennis Mammana Week of Aug 2-8, 2026 One of the most profound experiences a stargazer can have is to stand under the Milky Way on a clear August night far from city lights and see the wispy bunches of stars so tightly packed that they appear to the eye as a hazy band of light punctuated not only by bright individual stars but by tiny regions that appear as hazy clumps. Aim binoculars or a small telescope toward these "faint fuzzies," as astronomers affectionately call them, and you'll walk the same celestial path as Charles Messier did two and a half centuries ago. Messier was an 18th-century French astronomer who scanned the heavens in search of new comets, hoping that such discoveries would lead him to fame and fortune. He knew that comets often first appear as faint and colorless smudges of light that drift slowly among the stars, so that's what he was seeking. Along the way, however, he encountered dozens of such smudges that did not move. What these were he didn't know and, quite frankly, he didn't care. They weren't comets, so to avoid wasting more of his time on them — and to prevent other comet hunters from being similarly fooled — he began to compile a list of all these false comets he encountered on his nightly watch.

By Dennis Mammana Week of July 26 - Aug. 1, 2026 In a couple of weeks, I'll be telling you about the annual Perseid meteor shower. It should be a good one this year since moonlight won't reduce our view. Of course, if you've read my column regularly, you already know that stargazers will almost always see more meteors in the hours before dawn than during the evening, so that means we must rise early or stay awake all night. I know either can be quite a challenge for some, so this week I present to you an opportunity to practice getting up early and heading outdoors. Not for meteors — though you will almost certainly spot some early Perseids in the early morning sky — but to see two planets that haven't been visible during the evening hours for quite a while. During early dawn this week, early risers have the chance to see the only two planets of our solar system whose names begin with the letter M: Mars and Mercury. Before sunrise, look midway up in the eastern sky, and you'll spot a fairly bright reddish-orange light. Many people may think that's the Red Planet, but I assure you it's not. It's actually a star named Aldebaran, and it marks the fiery red eye of Taurus, the bull. Betelgeuse, in Orion, the hunter, also appears the same color. It's true that Mars also appears reddish-orange, but at this time, it appears 1.5 times fainter than Aldebaran and can be found to its lower left. Because it's so faint, you may have a tough time seeing its color easily, but aim binoculars or a small telescope in its direction and its ruddy hue will become quite apparent. Mars changes its distance from Earth, and therefore its brightness, quite dramatically over its orbit around the sun. It can go from about 35 million miles from us at its best oppositions; the next of these won't occur until September of 2035, when it will lie just 35.8 million miles from us. That will be a great time to view the planet with a small telescope, but right now, Mars lies nearly 186 million miles from us and appears quite small and faint. The other planet visible in the early morning hours this week is the elusive planet Mercury. I use the word elusive because this planet is the closest to the sun of all our solar system's worlds and, as such, never strays far from its glare. With its orbital motion combined with that of the Earth, Mercury flips from dusk to dawn about every three or four months, but it's always rather tough to spot. It's been said that the great 16th-century Polish astronomer Nicolaus Copernicus, who overturned the long-held notion that the Earth occupied the center of our planetary family, had never actually seen this world with his own eyes. Now I don't know if this is true, but it makes sense given what we know about weather conditions in Eastern Europe and how challenging Mercury is to spot. This week you can achieve something even the great Copernicus never could ... but you've got to get up pretty early to do it! Visit Dennis Mammana at dennismammana.com.

By Dennis Mammana Week of July 19-25, 2026 We can spend our time under the stars trying to find constellation figures from mythological times, but we'll always have limited success. If we really want to see pictures among the stars, I'm afraid we need to create our own. You may remember from previous articles that constellations are simply areas of the sky, and do not resemble their namesakes. Corvus looks nothing like a crow. Trying to find a bear in Ursa Major? Fuhgetaboutit! And Scorpius, the scorpion ... well, OK, there will always be one exception. No, if you want to see pictures among the stars, you must invent your own. And that's where asterisms come in. An asterism is a group of stars that we connect in our imaginations to look like something. Some of the easiest of these to create are geometrical figures. If you ever took a geometry class, you may recall that a point is the simplest of these — a figure with no length, width or depth. In the sky, every star forms a point; connect any three of these, and you'll create a triangle. One in particular, though, is different. It's larger and brighter, and we can find it midway up in our eastern sky after dark. It's called the Summer Triangle. It's not a constellation but rather an asterism made of three stars from three separate constellations, but that doesn't mean that early storytellers overlooked this prominent star grouping. For example, an ancient Chinese love tale tells that the star Deneb represents a magpie bridge over the Milky Way, which allows the separated lovers Altair and Vega to be reunited on only one summer night each year. The brightest of the stellar trio — and highest in the sky this week — is Vega, the most prominent star in the constellation of Lyra, the harp. It lies 150 trillion miles from us (about 25 lightyears); in other words, the light arriving tonight from Vega began its journey toward our eyes in 2001. The southeasternmost of the three stars is Altair, the brightest in the constellation of Aquila, the eagle. Its name comes from the Arabic Al Nasr al Tair, meaning in English "the flying eagle." Altair lies about 96 trillion miles (17 lightyears) from us. Not only is Altair one of the nearest stars, it's also one of the most rapidly spinning, completing one rotation in just 6.5 hours! Finally, farthest to the northeast lies Deneb, marking the tail of the great swan Cygnus, more easily recognized as the Northern Cross. It's not certain, but we think that Deneb could lie as far away as 2,600 lightyears from Earth. If it's truly that distant, this star could be one of the most brilliant in our entire galaxy, with a luminosity equivalent to 200,000 suns, and would generate more light in one day than our sun has produced since the days of Marco Polo at the end of the 13th century! With the overwhelmingly bright moonlight this week and next, the brightest stars are about all we'll be able to see, but you can still head outdoors to check out the brightest of the summer — the Summer Triangle.
