Swan Hellenic has again shown why it is the choice of curious adventurers across the generations, announcing full details of its 2026 Explore Space at Sea Series.
These exceptional cultural expedition cruises reach further and deeper, including into the far reaches of space, thanks to a unique partnership with the SETI Institute, an offshoot of NASA's High Resolution Microwave Survey, which began life more than 40 years ago, focused on the search for extraterrestrial intelligence (SETI).
The 2026 series will feature eleven renowned SETI Institute scientists, one per cruise with the exception of a very special voyage from Chile to Peru at the end of March/beginning of April, which will be accompanied by two research astronomers so guests can take full advantage of Chile's outstandingly clear skies for stargazing.
These ten extraordinary voyages will consequently bring Swan Hellenic guests specialist insights into the history and latest discoveries in astronomy, astrophysics, astrobiology and planetary science, as well as the quest to find other forms of life within and beyond our solar system.
Each SETI Institute scientist brings their own expert perspective, accompanying guests on their expeditions and delivering thought-provoking lectures aboard, while also mixing and socializing with guests throughout their voyage in the Swan Hellenic tradition.

Patrizia Iantorno, Chief Commercial Officer of Swan Hellenic commented: “We're very proud to unveil these unique 2026 Explore Space at Sea cruises with our partners at SETI, offering ten very different opportunities for curious minds to see what others don't, both on Earth and beyond”. About Swan HellenicSwan Hellenic was relaunched in July 2020 to proudly advance the spirit of cultural expedition cruising the company pioneered in the 1950s. Building on its British roots, the new company has a distinctly cosmopolitan culture dedicated to providing guests with global opportunities to see what others don't. Today's guests can choose to explore worldwide, from the Arctic and Antarctic to Africa, Latin America and the Asia Pacific, aboard Swan Hellenic's fleet of three purpose-built boutique ships.
Each of these luxurious new vessels features elegant Scandi-design interiors, extensive outdoor spaces and dedicated expedition facilities. SH Minerva and SH Vega, two 5-star Polar Code PC 5 expedition cruise ships with ice-strengthened hulls, were launched in December 2021 and July 2022. Both accommodate 152 guests in 76 spacious suites and staterooms, the majority with large balconies. SH Diana is a slightly larger PC 6 ice-class vessel launched in April 2023. She accommodates 192 guests in the same distinctive comfort and style in 96 staterooms and suites.
While sharing the unique design features of her sister ships, SH Diana also introduces certain key enhancements, including a dedicated presentation and lecture theatre overlooking the lounge, and on-board Tender boats to take guests ashore in addition to and in greater comfort than the customary expedition Zodiacs. Like her siblings, SH Diana features a state-of-the-art gym, spa, panoramic sauna, club room and swimming pool with poolside grill.
All three ships feature three dining venues – the Swan Restaurant, Club Lounge and Pool Bar & Grill – and are built in full compliance with SOLAS Safe Return to Port requirements. Dedicated to guests with a passion for adventure and cultural exploration, the company's meticulously planned itineraries explore the wild landscapes, wildlife, peoples and cultures of the world's less travelled and most historic regions.
The crews each include a team of up to 12 seasoned expedition guides, expert speakers and lecturers, for a total complement of 120 and 140 persons respectively, offering outstanding staff-to-guest ratios to deliver the highest standards of attentive personal service.
Swan Hellenic's cultural expedition cruises have always been distinguished by the company, guidance and expert lectures of famous explorers, seasoned expedition guides and leading authorities in their fields. Now, many of the cruises are also enriched by partnerships with unique organizations to bring very different experts on board in the same way, including JRE-Jeunes Restaurateurs and the SETI Institute.
Maris Culinary Discovery at Sea brings a different JRE gourmet chef aboard each in a series of exclusive cruises which take guests on a parallel voyage of gastronomic discovery. The SETI Explore Space at Sea Series brings a different world-renowned scientist from the SETI Institute aboard each cruise to provide guests with expert insights into the history and latest discoveries in astronomy, astrophysics, astrobiology and planetary science, as well as the quest to find other forms of life within and beyond our solar system.
On many cruises, guests can also participate in Swan Hellenic's Citizen Science partnerships, contributing valuable data obtained during their expeditions and on board, reporting cloud data with NASA, recording whale sightings with Happywhale, monitoring phytoplankton with the Secchi Disk Study, and Antarctic seabird numbers with Stony Brook University.
Headquartered in Cyprus, with offices in London (serving the UK and Ireland), Dusseldorf (serving Continental Europe), Monaco, Miami (serving the North American market), Hong Kong (serving Greater China, India and South-East Asia), Sydney (serving Australia-New Zealand) and Copenhagen (serving Scandinavia and Iceland), together with a partnership serving Japan, Swan Hellenic supports the travel trade with local specialist partners to provide clients with expert personal service worldwide.
