These are the best stargazing sites in North America
On a clear night last November, I spent over two hours in a dome atop nearly 7,000-foot-tall Kitt Peak, an hour outside of Tucson, peering through one of their 20-plus telescopes. The moonless night along with the high and dry climate enabled our guide to share bright and clear highlights, including the Andromeda galaxy, the ringed planet Saturn with several of its moons, and a globular cluster. Outside the dome, we simply marveled at the stunning clarity of our galaxy home, the Milky Way.
In the United States, 99 percent of us live in areas impacted by artificial light pollution. While dark skies are essential for many nocturnal creatures and ecosystems, recent studies have also touted the health benefits of darkness for humans. To help preserve and better connect us with this at-risk natural resource, DarkSky International has designated 155 dark sky places across the United States, six in Canada, and two in Mexico for stellar stargazing and efforts to preserve darkness.
Among the five categories of dark sky certification, sanctuaries meet the most stringent requirements, says Amber Harrison, DarkSky Places program manager, and many are in the western part of the continent in less populated areas. Designated in 2024, the world's largest international sanctuary—half the size of New Jersey—is in the high desert of the Oregon Outback. This 2.5-million-acre sanctuary includes broad and flat basins, mountain ranges with elevations from 4,700 to 8,000 feet, and alkali lakes, says Dawn Nilson, a DarkSky delegate who consulted on the process.
'With little or no light pollution, you see these celestial objects against an inky black, smooth canvas,' says Nilson. 'What's particularly special about the Outback is you get to see all those stars reflected on flat, calm, alkali lakes.' Nilson usually doesn't take her telescope along because there's no need. 'With your naked eye, you can see the many colors of the stars and star-making factories, like the Orion Nebula and the Lagoon Nebula.' In this pristine darkness, you might even spy your shadow cast by starlight.

Astro adventurers should be experienced 'remote travelers,' cautions Nilson, because there may be no cell service or facilities nearby. 'Always bring more layers for warmth than you think are necessary,' she advises. Outfitters, such as Bend's Wanderlust Tours, offer guided excursions, and Rose City Astronomers (partnered with the Oregon Museum of Science and Industry) hosts star parties. Oregon Astronomy will team you with telescopes and a NASA ambassador.
Other U.S. sanctuaries include Minnesota's Boundary Waters Canoe Area Wilderness and Maine's Katahdin Woods and Waters National Monument, the only one east of the Mississippi.
In the southwest, the Greater Big Bend International Dark Sky Reserve spreads 15,000 square miles across southwestern Texas and Mexico and is the largest Dark Sky reserve. You'll find a constellation of guided options, from public telescope viewing at the McDonald Observatory at the University of Texas at Austin to ranger-led night walks in Big Bend National Park to starry nights with DarkSky Texas.
On any dark sky-focused adventures, we all carry 'a superpower,' says Nilson: The human capacity for night vision. However, that scotopic, or low-level light vision, takes at least 30 minutes to activate fully and can be negated by a white flashlight or a glance at an illuminated screen. Seasoned stargazers recommend using red-light flashlights and scheduling your excursion during the new moon phase for optimal darkness.

With 28 certified dark sky communities and parks, Utah has the highest concentration of certified skygazing options in North America. That includes Rainbow Bridge National Monument, one of the world's largest natural bridges and also a sanctuary. The catch: Getting there requires a two-hour boat ride on Lake Powell followed by a one-hour hike. The site is considered sacred by many indigenous cultures, including the Pueblo of Zuni and the Hopi Tribe.
Straddling the Canadian border, the Waterton-Glacier International Peace Park is the first binational international Dark Sky Park and includes Montana's Glacier National Park and Canada's Waterton Lakes National Park. Known for its mountainous scenery and rich biodiversity, the area is a UNESCO-designated World Heritage Site, and both parks are UNESCO Biosphere Reserves. Dark Sky Guides in Waterton Lakes will maximize your viewing, and you can join Glacier's summertime ranger-led astronomy programs.
In Quebec's Eastern Townships, guided astronomy activities abound at Parc National du Mont Mégantic, including an aurora borealis show in the AstroLab museum and guided stargazing with telescopes. (Activities are in French.) To achieve reserve status, local municipalities replaced 2,500 light fixtures and reduced local light pollution by 25 percent. In the park, you can hike to three mountain summits and explore diverse forest ecosystems.
In Alberta, Jasper National Park is designated a Dark Sky Preserve by the Royal Astronomical Society of Canada, one of 17 in the country. The town is actually within the preserve's limits. Every October the Jasper Dark Sky Festival takes place, and features a planetarium and telescope viewing, Indigenous music and storytelling, and guided night hikes.
Lately, both urban and rural areas are darkening their skies to boost astrotourism. New Brunswick offers 'easy access to dark skies,' says Stéphane Picard of Cliff Valley Astronomy. 'Even in our cities, you're no more than 15 minutes away from a very dark sky.' The province has three dark-sky preserves designated by the Royal Astronomical Society of Canada, including Fundy National Park, known for the highest tides in the world. Other parks and towns are applying for designations to create a coastal stargazing corridor.
'When you're looking towards the Bay of Fundy from the New Brunswick coast, you're facing the southern half of the sky which is where mostly everything arises,' says Picard. 'We call that the rising tides and rising stars region.' The province hosts star parties with telescopes throughout the year.
Several jurisdictions have designed stargazing trails, including Tucson's Astro Trail with 11 dark sky experiences and Montana's Trail to the Stars with 45 recommended sites. With 12 Dark Sky Parks and another dozen working toward certification, Colorado has a self-guided 'Experience the Night' itinerary, chock full of daytime activities and night-gazing sites, including Great Sand Dunes National Park and Preserve. Mexico's first urban night sky place, Joya-La Barreta Ecological Park, between Querétaro and San Miguel de Allende, focuses on educating the public about the value of darkness.
(Why Tucson is one of the best places in the world to see the night sky)
East Coast residents seeking closer options can head to Pennsylvania's Cherry Springs State Park, which is within the larger Susquehannock State Forest and has laser-guided night sky tours. West Virginia's Watoga State Park's name derives from the Cherokee name for 'starry waters,' and travelers may spy abundant constellations here.
As stargazing gains in popularity, DarkSky International has developed its principles of responsible astrotourism, which emphasizes respect for local cultures and environmental health, along with sustainable growth. Hartley hopes that immersive dark sky experiences will inspire people to 'make some simple steps in and around your house and your neighborhood and your city to reclaim a little natural darkness.'

Early Forms of Cells Could Form in The Lakes of Saturn's Moon Titan
When NASA's upcoming Dragonfly probe skims the lakes of Saturn's moon Titan, it may encounter a froth akin to Earth's first signs of life, a new study suggests. Titan is strikingly similar to Earth in some respects. Like the planet we call home, its surface is covered with large lakes and seas of liquid. And, much like the water cycle on Earth, Titan's liquids – formed of hydrocarbons like methane and ethane – cycle between sky and shore, evaporating to form clouds and falling as rain. The water cycle is the circulatory system of life on Earth, and scientists suspect that similar processes on Titan could help life find its form there, too. Related: A new study in the International Journal of Astrobiology explores the possibility that proto-cell structures called vesicles could form on Titan. These simple bubbles of fatty molecules contain an inner pocket of goop surrounded by a membrane, similar to a cell. "The existence of any vesicles on Titan would demonstrate an increase in order and complexity, which are conditions necessary for the origin of life," explains planetary scientist Conor Nixon of NASA's Goddard Space Flight Center. "We're excited about these new ideas because they can open up new directions in Titan research and may change how we search for life on Titan in the future." Nixon and his colleague Christian Mayer, a physical chemist from the University of Duisburg-Essen in Germany, built on existing theories about how on Earth inorganic matter sprang to life in the dynamic spray of splashes and storms. The vesicles, Nixon and Mayer suggest, could form out of a complex process only possible on worlds with liquid cycling. On Titan, it would all start with a methane downpour that carries molecules from the atmosphere to a lake's surface. These molecules, called amphiphiles, have one polar end that attracts liquids, and one non-polar end that attracts fats. "Regarding amphiphilic compounds, the recent Cassini mission revealed the presence of organic nitrile. Such compounds… are basically amphiphilic and have the capability to self-aggregate in non-polar environments," Nixon and Mayer write. These molecules could aggregate to form a layer covering the surface of the lake. Then, when more droplets of liquid splash on this layer, they become coated with it before bouncing back into the air, forming a mist of enclosed droplets. A second dunk in the lake seals the deal: to become stable, vesicles need a double layer of amphiphiles, a bit like sealing two layers of velcro together. Intriguingly, a two-layered membrane such as this is a crucial part of a biological cell. Once double-dipped, the vesicles face a final test, something verging on biological evolution. "Stable vesicles will accumulate over time, and so will the corresponding stabilizing amphiphiles that are temporarily protected from decomposition," Nixon and Mayer write. "In a long-term compositional selection process, the most stable vesicles will proliferate, while less stable ones form dead ends… This leads to an evolution process leading to increasing complexity and functionality." If this process is happening on Titan, it could have major implications for how life arises from non-living matter. To confirm the hypothesis, scientists could use a laser, light scattering analysis and surface-enhanced Raman spectroscopy to look for amphiphiles drifting around in Titan's atmosphere, as an indication of the planet's potential for harboring life. Sadly, NASA's upcoming Dragonfly mission, set to arrive in 2034, won't be carrying the necessary instruments to detect vesicles. But it will conduct chemical analysis to see if complex chemistry is or has been occurring, which could reveal whether life is common if given the right environment, or if Earth just got lucky. The new research was published in International Journal of Astrobiology.

Titan's Methane Lakes Could Form Bubble-Like Structures Essential to Life, Scientists Say
On December 25, 2004, the Huygens probe separated from the Cassini spacecraft and landed on Titan's sandy surface. The probe survived for 72 hours on Saturn's largest moon, revealing a world that is chemically complex and more Earth-like than expected. For years, scientists have been intrigued by Titan as an alien world that might have the right conditions to host life, albeit in a very different form than on Earth. New research by NASA reveals that molecular precursors to life could form in Titan's methane lakes, allowing us a chance to learn how life originates and evolves in the universe. In a recently published paper in the International Journal of Astrobiology, a team of NASA researchers illustrates how vesicles, small, membrane-bound bubble-like compartments or sacs, could form naturally in the lakes of Titan. Vesicles are thought to play a vital role in the formation of life, an important step in making the precursors of living cells. The paper examines how the conditions for life could evolve in a vastly different environment than Earth, shedding light on our search for extraterrestrial life in the universe. Titan is the only other world, apart from Earth, that's known to have liquid on its surface. But unlike Earth's bodies of water, Titan's lakes and seas are not recommended for swimming, as they contain liquid hydrocarbons like ethane and methane. Water is crucial to life as we know it—but what if Titan's lakes have what it takes to harbor molecules required for life to evolve? The paper outlines a process by which stable vesicles might form on Titan based on the data that's been gathered so far about the moon's atmosphere and chemistry. On Earth, molecules known as amphiphiles have a split personality, with a hydrophobic (water-fearing) end and a hydrophilic (water-loving) end. When in water, the molecules naturally organize into ball-like spheres, resembling soap bubbles, whereby the hydrophilic part faces outward to interact with the water while its hydrophobic counterpart shies away on the inside of the sphere. This allows the molecules to form complex structures and may have led to primitive cell membranes in early Earth. On Titan, these vesicles could form thanks to the moon's complex meteorological cycle, according to the paper. The methane in Titan's atmosphere forms clouds, which rain on the surface to create river channels that fill up the moon's lakes and seas. The liquid on the surface then evaporates to form clouds once again. The researchers behind the new study suggest that spray droplets from the rain and the surface of the sea could be coated in layers of amphiphiles. When the droplets land on the surface of a pond, the two layers of amphiphiles meet to form a double-layered vesicle. Over time, the vesicles would be dispersed throughout the pond and would compete in an evolutionary process that could lead to the formation of primitive protocells. 'The existence of any vesicles on Titan would demonstrate an increase in order and complexity, which are conditions necessary for the origin of life,' Conor Nixon, a researcher at NASA's Goddard Space Flight Center and co-author of the new study, said in a statement. 'We're excited about these new ideas because they can open up new directions in Titan research and may change how we search for life on Titan in the future.' NASA is preparing to launch Dragonfly, the agency's first Titan mission, in July 2028. The rotorcraft lander will explore the surface of Saturn's moon and gather data about its atmosphere and geology. Dragonfly will help scientists better understand the bizarre world where life could form under vastly different conditions.

Can You Drink Saturn's Rings?
In November 2024 I was interviewed for a marvelous NPR podcast called Living On Earth about my latest popular science book, Under Alien Skies. While prepping for the show, one of the producers asked me a question that was so deceptively simple, so wonderfully succinct, and came from such an odd direction that I was immediately enamored with it. Can you drink Saturn's rings? After pausing for a moment to savor the question, I replied with one of my favorite responses as a scientist and science communicator: 'I don't know. But I'll try to find out.' On supporting science journalism If you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today. So I did. And to my delight, the nuanced answer I found is another personal favorite: Yes! But no. Kinda. It depends. I love this sort of answer because it arises when the science behind a seemingly easy question is very much not so simple. So please grab a frosty glass of (locally sourced) ice water, sit back and let me explain. Saturn's rings were likely first seen by Galileo in 1610. His telescope was fairly low-quality compared with modern equipment. And through its optics, all he could see were a pair of blobs, one on each side of the planet's visible face; he referred to them as Saturn's 'ears.' It wasn't until a few decades later that astronomers realized these 'ears' were actually a planet-encircling ring. Much was still unclear, but one thing was certain: the ring couldn't be solid. The speed at which an object orbits a planet depends on its distance from that world, and Saturn's ring was so wide that the inner edge would orbit much more rapidly than its outer edge, which would shear anything solid apart. Astronomers came up with a variety of different ideas for the structure, including a series of solid ringlets or even a liquid. It wasn't until the mid-1800s that the great Scottish physicist James Clerk Maxwell proved none of these would be stable and instead proposed what we now know to be true: the structure around Saturn was made of countless small particles, which were far too tiny to be seen individually from Earth. Further, these small objects form not just one ring but several, and these major rings are designated by letters in order of their discovery. The A ring is the outermost bright ring. Just interior to it is the bright and broad B ring, which contains most of the entire ring system's mass. Interior to that is the darker C ring, which leads down to the faint D ring that extends almost to the upper atmosphere of Saturn itself. In total these rings stretch across nearly 275,000 kilometers—two thirds of the Earth-moon distance! Despite their immense sprawl, the rings are almost impossibly flat, in many places just about 10 meters thick. Seen exactly edge-on, they look like a narrow line cutting across the planet. But what are they made of? Observations over the centuries have revealed that the main constituent of the rings is startlingly simple: water ice! Good ol' frozen H 2 O is extremely common in the outer solar system and makes up most of many moons and other small bodies there. In fact, in situ observations performed by the Cassini spacecraft— which orbited Saturn for more than a dozen years — showed that in some places the rings were made of almost perfectly pure water ice. Even better, most of the ring bits are a few centimeters across or smaller—the size of ice cubes, so they're already conveniently packaged. Sounds great! All you need to do then is scoop up some chunks, warm them—a lot (the average temperature of the rings is about –190 degrees Celsius)—and have yourself a nice, refreshing sip. But not so fast. This is where it gets more complicated. The spectra of the rings also show that they aren't made of absolutely pure ice. There's other material in the rings, and even though we're typically talking about contamination of less than 1 percent by mass, it's not clear what this stuff is. Scientists' best guess is that it comes from the impacts of micrometeorites, tiny particles whizzing around the outer solar system. This material is therefore likely composed of silicates (that is, rocks) or abundant metals, namely iron. Neither of these will harm you, although the U.S. Environmental Protection Agency recommends no more than 0.3 milligram of iron per liter of potable water (to avoid a metallic taste). You'd better run a magnet over your ring water before you drink it—and you should probably filter out any silicate sediments while you're at it. On the other hand, the rings' spectra suggest the presence of some unknown carbon-based contaminants as well. One likely candidate would be complex organic molecules called polycyclic aromatic compounds, or PAHs, which are relatively prevalent in space; many giant stars blow out PAH-laced winds as they die. One molecule that is commonly present in PAHs is cyanonaphthalene, which is considered carcinogenic. (It's unclear, though, how much exposure poses risks to humans —or, for that matter, whether this specific molecule actually exists in the rings.) It's best to be cautious and avoid these potential contaminants by picking your rings carefully. The abundance of water ice is highest in the outer A and middle B rings, for example, whereas the C and D rings appear to be the most contaminated. So, generally speaking, it'd probably be better to opt for ice from A or B while skipping C and D entirely. There could also be other ices in the rings, too, including frozen methane and carbon dioxide. Methane should bubble out when the ice is liquefied, and of course CO 2 is what makes carbonated beverages fizzy. That might actually add a fun kick to drinking from the rings! There are other rings, too, outside the major ones we've already mentioned. For example, Saturn's icy moon Enceladus boasts dozens of geysers that blast liquid water from its interior out into space. This material forms a faint, fuzzy ring (the E ring) that, again, is mostly water ice but also contains small amounts of silicates—and noxious ammonia—so I wouldn't recommend it. Still, all in all, it looks like— if carefully curated and cleaned —Saturn's rings are indeed drinkable! How much water is there in the rings, then? The total mass of the rings is about 1.5 × 10 19 kilograms, which, correcting for the density of ice and the removal of contaminants, should yield about 10 quintillion liters of water—enough to keep every human on Earth well hydrated for more than a million years. Eventually, if and when humans start to ply the interplanetary space-lanes, they'll need extraterrestrial sources of water because lifting it from Earth is difficult and expensive. Saturn's rings might someday become a popular rest stop. And, oh my, what a view visitors would have as they filled up!
