7 Astronomy-Centered Cruises That Will Leave You Starstruck

Even before the recent Artemis II mission reignited the space race, travelers were tuning their antennas skyward. In 2024, some 70 million pairs of safety glasses were sold to protect Americans watching the solar eclipse that swept across the US, which millions of people traveled to observe. This August, another solar eclipse will be visible from Greenland and Iceland to northern Spain—coinciding with summer cruises in northern waters.Jane WoolridgeWhen her TV broke in her 20s, Jane Wooldridge spent the repair fees on a plane ticket to Europe. She's been an avid explorer ever since, visiting more than 120 countries on all seven continents by foot, car, train, cruise ship, vintage Airstream, camel, chicken plane, and river raft. She now lives in Miami, Cruise Ship Capital of the World, and frequently writes about cruising. Her favorite trips combine cultural and nature exploration with great pillows, noteworthy cuisine and fine wines. A past president of the Society of American Travel Writers, she is a winner of the Lowell Thomas Travel Journalist of the Year and author of “Comfort in the Wild: 100+ Idyllic Nature Destinations, No Roughing it Required” published by Frommer's.But cruise lines aren’t just viewing platforms for eclipses and other celestial phenomena. Many offer ongoing sky-watching programs with scientific experts to help astronomy buffs explore the heavens more deeply. Travelers are taking note. “We’ve really entered the era of the ‘floating observatory,’” says Rosemarie Reed, senior vice president of marketing for Cruises.com. “Our customers have told us they’re not looking to check a destination off a map—they want a front row seat to the universe. We’re seeing a surge in these types of itineraries because they turn a great vacation into the kind of story you’ll still be telling 20 years from now.”For me, there’s another reason: When I gaze into galaxies far, far away, the nonstop craziness of modern life is replaced with possibilities. Chasing that same feeling yourself? Below are seven lines offering astronomy-centric voyages.The 2026 August eclipse with OceaniaIn August 2026, four Oceania Cruises sailings will cross the paths of the solar eclipse, offering more than 90% visibility, weather permitting. A fifth, departing July 30 from Copenhagen, will offer 100% visibility as the 1,250-passenger Oceania Marina departs the part of Grundarjordur, Iceland, on its way to Reykjavik. All five sailings stretch the stellar experience beyond the eclipse itself with expert speakers (astronomer Dennis Mammana will join Marina) and whimsical culinary touches like star-shaped sandwiches and half-moon shrimp empanadas.Celebrity Flora, FL, Galapagos Islands, Jacuzzi, hot tub, pool, The Vista, sunset, architectural, loungeQuentin BaconStarry nights with Celebrity CruisesGazing at the constellations of both the northern and southern hemispheres usually requires a flight. But on Celebrity Flora’s seven-night sailings from Baltra, Ecuador, the ship’s 100 guests can see both in a single night from the Galápagos Islands, near the Equator and far from the light pollution that plagues more populous places. Telescopes set up on an open-air star-gazing platform allow guests to gaze deep into the dark skies and look beyond familiar constellations like The Big Dipper. Those who can’t tear themselves away from the glittering heavens can book an overnight stay on the ship’s deck.HurtigrutenChasing the Northern Lights with HurtigrutenFor years I’ve pursued the dancing glow of the northern lights, making two winter-season trips to Iceland and one to Sweden. I’ve yet to see them—which is why companies like Hurtigruten and Havila Voyages offer a northern lights promise on their two-week voyages: If a passenger doesn’t see the Aurora Borealis during specified sailings, they get a second cruise for free.Hurtigruten is pushing into new territory, offering sailings with its Chief Aurora Chaser Tom Kerss. The astronomer and author explains the aurora and other heavenly phenomena on two 2027 “Signature” cruises departing March 12 and 26. A land-sea tour on March 12 includes a nighttime husky safari, snowmobile rides, and an overnight in a glass igloo. Hurtigruten also offers “coastal” voyages that operate like local ferries, with multiple short stops daily. Select winter sailings also include expert talks and a visit to Tromso’s planetarium.Royal connections with CunardPlanetariums at sea? Three Cunard ships—Queen Anne, Queen Mary 2, and Queen Victoria—have them, allowing for science shows on a regular basis. On some voyages, ongoing space programming is enhanced with talks by members of the Royal Astronomical Society, which has partnered with Cunard since 2008. On August 25, 2026, astrophysicist Dr. Shenona Urquhart will join guests aboard the 2,600-passenger Queen Mary 2 for conversations on topics including the Big Bang, human space flight, dark matter, and extraterrestrial intelligence. She’ll also share tips for novice stargazers on the 11-night sailing through the Norwegian fjords, which goes in and out of Southampton, England.Coral Discoverer for the Total solar eclipse 2028 cruise: The Kimberley, Western Australia Coral ExpeditionsScience-centered voyages with New Scientist Discovery ToursIn 2015, New Scientist added “discovery tours” to the weekly magazine it has been publishing since 1956, bringing along scientific experts to unlock the experience. On August 7, award-winning science journalist Jamie Carter and other experts will join a 13-day expedition cruise roundtrip from Reykjavik, Iceland, aboard Aurora Expeditions’ 130-passenger Sylvia Earle. For those peering into the future, New Scientist will host a 12-day expedition cruise in Australia’s Kimberley region coinciding with the July 2028 solar eclipse. British astronomer Martin Griffiths will join the exclusive sailing aboard Coral Expedition’s 72-passenger Coral Discoverer.Otherworldly exploration with Swan HellenicThe SETI Institute’s acronym—the Search for Extraterrestrial Intelligence—speaks to a question that many of us ponder: Is there life beyond Earth? This isn’t science fiction; the Institute’s work supports NASA and studies life in extreme conditions. Since 2022, SETI’s experts have brought that broad knowledge to the Institute’s partnership with Swan Hellenic, which offers multiple SETI cruises each year. Upcoming sailings include a six-night voyage from Portugal to the Canary Islands, departing September 7 with software engineer Peter Tenenbaum, whose team developed the code for monitoring space matter, as a guest lecturer.Starstruck in the Amazon with A&K SanctuaryTruly dark skies have become such a rarity that light-free places are now officially designated by Dark Skies International. Cruise ships that traverse the Atlantic and Pacific have an advantage—as do those that sail truly remote waters. That’s the case with Pure Amazon’s itineraries in Peru’s Payaca Samiria National Park. Each night, weather permitting, an expert guide leads stargazing sessions for those interested on the 24-passenger ship.
