Borrego Night Sky Tours

By Dennis Mammana Week of July 5-11, 2026 There's a constellation in our night sky right now that is somewhat unknown to stargazers. Despite being huge — it's the 11th-largest in all the heavens — it has no stars brighter than the North Star, so you won't find it easily without a pretty dark sky. Its name is Ophiuchus (oh-fee-YOU-kuhs), and if you'd like to find it this month, you'll need to get away from the city lights and gaze midway up in the southeast shortly after dark. Ophiuchus (the serpent-bearer) represents Aesculapiu, the ancient Greco-Roman god of medicine, healing and physicians, and its brightest star is named Rasalhague, which is Arabic for "Head of the Snake Charmer." Draped from one side of Ophiuchus to the other lies Serpens — the only two-part constellation in the heavens — with its head on one side (Serpens Caput) and its tail on the other (Serpens Cauda). I admit that it requires quite an imagination to find these star groupings, but once you do, you'll know them forever. In fact, you may even recognize this shape, especially if you've ever searched online for the name of a physician. Quite often, you'll find the image of two serpents wrapped around a vertical staff that appears topped by a round knob and is flanked by wings. It's known as the "caduceus," and since 1902, when the U.S. Army adopted it as the insignia of its Medical Corps, it has been the familiar emblem of the American medical profession. Many medical associations — including the World Health Organization — use what some consider to be the "correct" and traditional symbol of medicine: the staff of Asclepius, with a single serpent encircling a staff. Either way, people have long associated the serpent with medicine. Once you find its stars, you'll see that Ophiuchus lies along some of the thickest star clouds of the Milky Way. If you've managed to get yourself to a rural location with a non-light-polluted sky, you'll have little trouble finding the hazy band of the Milky Way passing near this constellation, along with the bright reddish-orange star Antares (the heart of Scorpius, the scorpion) just to its lower right. Be sure to take binoculars with you so you can scan this celestial region. Here you'll find countless "faint fuzzies" (as amateur astronomers affectionately call deep-sky objects). Many of these are star clusters — collections of dozens, hundreds or even thousands of stars held together by gravitation — and interstellar nebulae, where stars and planetary systems are constantly forming. Now, while you're gazing at the stars of Ophiuchus, here's a little tidbit to wrap your head around: This constellation is not one of the official signs of the zodiac, but it should be. Why, you ask? Because the sun spends three times as many days in front of the stars of Ophiuchus as it does in Scorpius. So why, then, is this constellation missing from the official zodiacal signs in horoscope tables? Your guess is as good as mine. Just remember, if you were born between Nov. 29 and Dec. 17, you're not a "Scorpio" or "Sagittarius," as you might have thought. You're actually an Ophiuchan! Make of that what you will...

Don't Miss These Summer Night Sky Events

By Dennis Mammana Week of June 28 - July 4, 2026 It was bound to happen: The heat of summer has arrived at my desert home. As I write these words, it's 115 F outside, and it's just the beginning of the blistering heat we'll experience for months. This is no surprise, of course. We're all quite familiar with this seasonal pattern; in fact, most of us learned in grade school about the seasons and what causes them, but you'd be surprised how little some people remember of those basic lessons. I was stunned when I first heard of a 1987 video in which filmmakers Matthew H. Schneps and Philip Sadler of the Harvard-Smithsonian Center for Astrophysics interviewed recent Harvard University graduates, faculty members and alumni — some with science backgrounds — and asked them a simple question: What causes our seasons? Twenty-one of the 23 people interviewed did not know the answer. This is Harvard, people. Harvard! If you can't believe it, watch it online here. Oh, sure, they offered elaborate explanations and tried to be convincing, but it's obvious they had no clue. The most common reason they cited for the summertime heat was that the Earth lies closest to the sun at that time of year, and the cold of winter is caused by our greater distance from the sun. Sounds perfectly reasonable, doesn't it? But it's wrong. So very wrong. Now it is true that our planet orbits the sun not in a circular path but in an elliptical path, and that our distance from the sun varies throughout the year, but only by about 3%. What seems counterintuitive, however, is that we're closest to the sun not during our Northern Hemisphere summer but during our winter! In 2026, the Earth will reach its farthest point from the sun ("aphelion") on July 6, when we will lie 94,502,961 miles from our star. This occurs during the Northern Hemisphere summer. The Earth's nearest point ("perihelion") won't arrive until Jan. 2, 2027 (during our winter), when we'll be 91,406,556 miles from the sun. Of course, if you happen to live in the Southern Hemisphere, where seasons are reversed from those north of the equator, our planet's perihelion does occur during their summertime. But that's a story for another time. So, if our distance from the sun doesn't cause seasonal temperature changes throughout the year, what does? Well, as we all learned in third grade, it's the tilt of the Earth's axis. Our planet is tipped about 23.4 degrees to the plane of its orbit around the sun. From mid-March to mid-September, the Earth's Northern Hemisphere is tilted toward the sun, allowing solar rays to beat directly down upon us. During these longer days, heat accumulates in our atmosphere while having little time to escape into space during the much shorter nights. In other words, it's not our changing distance from the sun that causes the buildup of summer heat; it's the tilt of our planet that produces long days and short nights — just as it always has. Unfortunately, few still seem to understand this simple phenomenon, and I suspect if we did this same interview today, we'd see even less informed answers than four decades ago!

Prepared with information from ABDNHA's Dark Sky resources, Michael Poirier, Astrophotographer, and the Sky Calendar from Michigan State University. Learn more about Borrego Springs dark skies at: https://abdnha.org/darksky/sky / Note: You can subscribe to the Sky Calendar from Abrams Planetarium, Michigan State University, 755 Science Rd, East Lansing, MI 48824. Borrego Springs offers some of the darkest skies in Southern California, making summer an excellent time to observe the Milky Way, planets, meteor showers, and other celestial events. Here's what to look for in June and July 2026. Early June Sunrise: 5:38 a.m. Sunset: 7:50 p.m. PST Day Length: 14 hours 12 minutes June Highlights June 1 (Monday) Venus and Jupiter appear within 8° of each other in the west-northwestern sky after sunset. June 3–16 Milky Way viewing conditions are excellent, with dark, moonless skies after nightfall. The Milky Way rises at 10:57 p.m. on June 7 and as early as 10:30 p.m. on June 14. It remains visible for up to 4 hours and 29 minutes. June 6–13 Grand Canyon Star Party, Arizona. Learn more at www.grandcanyon.org . June 11 (Thursday) Venus, Jupiter, and Mercury span their shortest angle in the evening sky, just 13.2° apart. June 15 (Monday) New Moon — one of the darkest nights of the month for stargazing and astrophotography. June 15 (Monday) Mercury reaches greatest elongation, 24.5° from the Sun, making it the best evening appearance of the year shortly after sunset. June 21 (Sunday) June Solstice marks the beginning of summer in the Northern Hemisphere. It is the longest day of the year with 14 hours and 20 minutes of daylight. June 22–July 2 June Bootids Meteor Shower. June 29 (Monday) Full Moon rises at 8:17 p.m. and sets at 5:04 a.m. June 30 (Tuesday) Asteroid Day. Early July Sunrise: 5:41 a.m. Sunset: 7:59 p.m. Day Length: 14 hours 18 minutes July Highlights July 5 (Sunday) The Milky Way rises at 9:38 p.m. and remains visible for 3 hours and 58 minutes. July 12 (Sunday) The Milky Way rises at 9:34 p.m. and remains visible for 3 hours and 35 minutes. July 14 (Tuesday) New Moon — ideal conditions for stargazing and astrophotography. July 15 (Wednesday) Mercury reaches greatest elongation, 24.5° from the Sun. July 28–29 (Tuesday–Wednesday) Delta Aquariids Meteor Shower peaks. July 29 (Wednesday) Full Moon rises at 8:17 p.m. and sets at 5:04 a.m. The Planets and the Milky Way in June Evening Planets Venus and Jupiter dominate the western sky after sunset throughout June. Around June 8–9, the two planets appear in conjunction, creating a striking close encounter in the west-northwestern sky. Venus, often called the "Evening Star," shines brilliantly as it moves from Taurus toward Gemini and climbs higher in the evening sky each night. Jupiter remains nearby and is also easily visible. Mercury becomes visible low in the western sky during the second half of June. June 15 offers the best viewing opportunity, as Mercury reaches its greatest elongation and highest apparent position above the horizon. Morning Planets Saturn and Mars are visible before sunrise. Mars remains low in the east-northeast, while Saturn rises higher from the east to east-southeast. Early June provides a chance to see the two planets relatively close together. Summer Milky Way Summer is the prime season for viewing the bright central core of the Milky Way. From June through August, the galaxy's core rises in the southeastern sky and becomes one of the most spectacular sights available to dark-sky observers. June Bootids Meteor Shower The June Bootids occur annually from June 22 through July 2 and peak around June 27. Most years produce only one or two meteors per hour. However, this shower has occasionally surprised observers with dramatic outbursts. In 1998, rates briefly reached approximately 100 meteors per hour. The shower originates from debris left by Comet Pons-Winnecke, which orbits the Sun every 6.3 years. June Bootids are known for their unusually slow speed, entering Earth's atmosphere at approximately 14 kilometers per second. Asteroid Day – June 30 Asteroid Day is a United Nations-sanctioned global awareness campaign held annually on June 30. The event educates the public about asteroid impacts, planetary defense, and ongoing research into near-Earth objects. The date commemorates the Tunguska Event of June 30, 1908, when a massive airburst explosion flattened approximately 830 square miles of Siberian forest. The blast is estimated to have released energy equivalent to between 3 and 50 megatons of TNT, making it the largest recorded impact event in modern history. For more information, visit www.un.org. Delta Aquariids Meteor Shower The Delta Aquariids meteor shower peaks on the night of July 28 and the morning of July 29. This annual shower can produce up to 20 meteors per hour under ideal conditions and is associated with debris from Comets Marsden and Kracht. The shower runs from July 12 through August 23 each year. Unfortunately, the 2026 peak coincides with a Full Moon, which will wash out many fainter meteors. Patient observers may still catch some of the brighter meteors throughout the night. The meteors appear to radiate from the constellation Aquarius but can be seen anywhere in the sky.

Regional event celebrates the night sky, science, and dark sky preservation Borrego Springs residents who enjoy stargazing, astronomy, and protecting the night sky may want to mark their calendars for the 2026 San Diego Dark Sky Festival , scheduled for August 15 from 3 p.m. to 11 p.m. at Julian Union High School in Julian. The festival will feature distinguished speakers, telescope viewing, hands-on activities, educational exhibits, and opportunities to learn more about the growing dark sky movement throughout San Diego County. The event is organized by DarkSky San Diego County and regional partners committed to reducing light pollution and preserving access to natural darkness. Activities are designed for families, students, amateur astronomers, and anyone interested in the night sky. Festival organizers describe it as a celebration of stars, science, and community. For Borrego Springs residents, the festival highlights a cause that has become part of the community's identity. Borrego Springs was California's first International Dark Sky Community , earning recognition for its efforts to reduce light pollution and preserve exceptional night-sky viewing. Julian followed with its own International Dark Sky Community designation in 2021, creating a network of dark-sky advocates in San Diego County's backcountry. The festival also showcases the growing regional movement to protect dark skies. Organizations from Borrego Springs, Julian, Fallbrook, Mission Trails Regional Park, and the Laguna Mountain area are working together to promote responsible lighting and preserve natural darkness for future generations. Visitors can expect telescope viewing, astronomy demonstrations, educational booths, and presentations on the importance of natural darkness for wildlife, human health, and energy conservation. Similar festivals have drawn large crowds and provided opportunities for the public to experience some of Southern California's best night skies. For many Borrego Springs residents, the event offers a chance to connect with neighboring dark-sky communities while celebrating one of the region's greatest natural resources—the star-filled skies that make both Borrego Springs and Julian special destinations for stargazing. ------------------ Fun Local Fact: K-RAM 90.5 FM at 730 Christmas Circle recently received a Night Sky Friendly Business Certificate of Merit from the Borrego Springs Dark Sky Coalition. The building also houses a Dark Sky visitor center and Borrego Valley Realty, where realtor Mary Watkins helps visitors learn more about protecting Borrego Springs' famous night skies.

One of the things that makes Borrego Springs special happens after the sun goes down. Borrego Springs became California's first International Dark Sky Community in 2009 and was only the second community in the world to receive the designation. The certification recognizes communities that actively work to reduce light pollution and protect the night sky for future generations. Earlier this year, a Dark Sky presentation highlighted K-RAM 90.5, XL Fuel Stop, and Borrego Holiday Homes as examples of businesses using responsible lighting practices that help preserve Borrego Springs' internationally recognized night skies. Ram Media Foundation Updates Exterior Lighting The Ram Media Foundation building at 730 Christmas Circle, now home to K-RAM 90.5, the Borrego Sun, and Borrego Valley Realty, removed older unshielded, high-lumen fixtures that reflected light outward around the property. The updated lighting includes shielded fixtures and a downward-facing reflector along the front walkway. These improvements provide lighting where it is needed while reducing unnecessary glare and light escaping into the night sky. XL Fuel Stop Reduces Sky Glow XL Fuel Stop was highlighted for using fully shielded lighting that directs light where it is needed instead of into the night sky. According to the presentation, a bright light mounted atop a high pole was turned off, and after-hours lighting levels were reduced. These changes help minimize sky glow while maintaining safety and visibility for customers. Borrego Holiday Homes Improves Efficiency Borrego Holiday Homes was highlighted as another example of responsible lighting practices. The property reduced excessive brightness by lowering lumen levels and using shielding that directs light downward. The result is reduced glare, improved efficiency, and lighting that better serves guests without unnecessarily illuminating the surrounding area. Why Dark Skies Matter According to the Borrego Springs Dark Sky Coalition, light pollution is the human-made alteration of outdoor light levels from those occurring naturally. Excessive brightness can create visual discomfort, affect wildlife behavior, disrupt human circadian rhythms, and diminish our ability to see the stars. Responsible lighting does not mean eliminating outdoor lighting. Instead, it means using the right amount of light, directing it where it is needed, and avoiding unnecessary brightness. The Borrego Springs Dark Sky Coalition was formed in 2007 by local residents seeking Dark Sky certification. Facilitated by the Anza-Borrego Desert Natural History Association (ABDNHA), the coalition continues to educate residents, businesses, and visitors about responsible lighting practices that help preserve Borrego Springs' exceptional nighttime environment. The improvements made by K-RAM 90.5 , XL Fuel Stop, and Borrego Holiday Homes demonstrate that protecting dark skies can go hand in hand with safety, efficiency, and good business practices. For residents and visitors alike, these efforts help ensure that Borrego Springs remains one of the best places in Southern California to experience a sky filled with stars.

June 2026 Skywatching Highlights

By Dennis Mammana Week of June 7-13, 2026 During one of my recent night sky tours, an elderly guest gazed into the sky and asked if the stars ever move. He said the constellations look the same now as when he was a child, and he was convinced that nothing in the heavens ever changes. It was an excellent observation but one that didn't consider an important fact: Human time scales are considerably different than cosmic time scales. Even the healthiest of humans will live at most about a century, and during our lives, we measure time in seconds, minutes, hours, days, weeks, months, years and decades. The cosmos, on the other hand, has been around for nearly 14 billion years, and everything takes much longer to occur. To recognize changes in the universe, astronomers must think on a more cosmic scale. When we do, we find that the universe is remarkably active. Stars are forming, consuming their nuclear fuel, and dying, and all are racing through our galaxy at tremendous speeds. Expecting to see changes in any star's appearance or the shapes of constellations over even a full human lifespan just isn't possible. To understand this, consider Barnard's Star, visible only through a telescope from the Earth's Southern Hemisphere. This star tears through our galaxy at a speed of some 88 miles per second, yet from our terrestrial vantage point six lightyears away, Barnard's Star requires three and a half centuries to cross a segment of the sky only the width of your outstretched little finger. Of course, we can't watch this movement with our eyes — or even through powerful telescopes — but by using sophisticated earthbound and satellite technology, astronomers can precisely measure these stellar speeds and directions of motion. Measure the speeds and directions of enough stars, and we find some interesting patterns. For example, stars that appear roughly in the direction of the summer star Vega (now shining low in the northeastern sky after dark) seem to be spreading out from a central point, while those on the opposite side of the sky (near Sirius, setting in the southwest around sunset) appear to be converging on one another. What this means is fascinating. Our sun's own motion is carrying it (along with the planets of our solar system) toward the stars near Vega — a point we know as the solar apex — and away from those near Sirius (known as the solar antapex). This phenomenon isn't difficult to visualize. Imagine you're driving along a highway from one city to another. The buildings in front of you appear to become more widely separated as you approach, while those behind you appear to converge more tightly. This is exactly what's happening in our section of the galaxy. Our sun is moving at some 12 miles per second toward a point in our sky not far from the bright star Vega. Of course, we can't see this movement, but it's fun to stand outdoors on a clear night and imagine our sun and Earth racing outward toward Vega. Now, if you're worried about a collision with this star ... well, fuhgetaboutit. Even at this remarkable speed, we'd need some 5,300 human lifetimes to get there!
