Reserve a guided night sky tour with astronomer Dennis Mammana

Summer Milky Way season is returning to Borrego Springs, bringing some of the year's best opportunities to explore the night sky. Deep within the glowing band of the Milky Way are stellar nurseries, sparkling star clusters, colorful nebulae, and the remnants of long-dead stars waiting to be discovered.


Astronomer Dennis Mammana is once again offering personalized telescopic tours of the cosmos under the dark skies of the Anza-Borrego Desert. With limited summer dates available, visitors are encouraged to make reservations early through Borrego Night Sky Tours.


Borrego Springs is known for having some of the best stargazing conditions of any community in the United States. The combination of dry desert air, minimal light pollution, and more than 300 clear nights each year has made the community a destination for astronomy enthusiasts from around the world.


Borrego Springs was designated California's first International Dark Sky Community in 2009 by the International Dark-Sky Association, recognizing the community's commitment to protecting and restoring natural darkness. The surrounding Anza-Borrego Desert State Park was later designated an International Dark Sky Park in 2018, helping preserve some of the darkest skies in Southern California.


The community has earned national recognition for its stargazing opportunities. Over the years, Borrego Springs has been featured by USA Today, KCET, Afar Magazine, The Active Times, the San Francisco Chronicle, Livability, and Time Out, which ranked Borrego Springs among America's top summer stargazing destinations.


For more than five decades, Dennis Mammana has shared the wonder of astronomy through writing, photography, lectures, planetarium productions, television appearances, and guided sky tours. An astronomy writer, lecturer, and internationally recognized night sky photographer, Mammana has authored books and hundreds of articles on astronomy and has led observing tours on six continents.


His astrophotography has been featured numerous times as NASA's Astronomy Picture of the Day, and he is one of only a handful of American members of The World at Night (TWAN), an international team of leading night sky photographers.

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.
