Alaska already has glaciers, whales, old gold-rush towns, wild seafood, and mountains. But Princess Cruises is taking the year by storm with something bigger than a standard summer schedule. The line is sending eight ships to Alaska, adding new North-to-Alaska programming, and giving travelers more ways to turn their trip into a full land-and-sea adventure.

Princess Is Going Bigger Than Ever

The 2026 Alaska season gives Princess its largest presence in the region to date, with eight ships, 180 departures, and visits to 19 destinations. Travelers are not boxed into a narrow route or one small batch of dates. The ship lineup includes Star Princess, Coral Princess, Royal Princess, Ruby Princess, Grand Princess, Emerald Princess, Discovery Princess, and Island Princess. For anyone comparing Alaska cruise options, that much capacity means more itinerary choices.

Star Princess Gives The Season A New Headliner

Star Princess is the newest ship in the Princess fleet. This matters because Alaska cruising can easily feel like a trade-off between destination and ship experience. Princess is putting one of its newest vessels into one of its most important regions. Star Princess also hosts the new Après Sea experience inside The Dome, a high-positioned venue designed around big views.

Glacier Days Get The Full Main-Event Treatment

Glacier viewing has always been one of Alaska cruising’s biggest draws, but Princess is giving it extra structure through “The Glacier Experience: A Signature Princess Day.” On select Glacier Bay sailings, guests get close-up glacier views, live narration, and Park Ranger commentary from the bridge and open decks. There are also theater presentations and Junior and Teen Ranger programming. VIP viewing areas and bowfront access add another layer for guests who want the best possible look at the ice.

The Trip Can Extend Deep Into Alaska By Land

Princess has long built part of its reputation around cruisetours that combine time at sea with inland travel. A seven-night sailing can deliver a strong Alaska trip in itself. However, inland travel opens the door to scenic train journeys, Princess Wilderness Lodges, and routes to places such as Denali, Kenai, and the Mt. McKinley lodge area. The 2026 season continues to lean into sea-and-land travel.

North To Alaska Makes The Ship Feel Local

Princess first introduced its North to Alaska program in 2015, and in 2026, every Princess ship sailing in Alaska will carry the new programming. The whole idea is to bring local culture, food, personalities, and storytelling on board so guests learn something about Alaska between ports. This includes Native Alaskan speakers, naturalists, enrichment presenters, and destination-focused events that connect the trip to the place outside the ship. Names in the speaker series include Tlingit voices, Alaska Native educators, writers, and photographers.

Alaska Seafood Gets A Bigger Seat At The Table

Princess is leaning into Alaska’s food identity with “A Taste of The Great Land.” The 2026 specialty restaurant offerings feature sustainably sourced, wild-caught Alaskan seafood created with regional suppliers. Crown Grill offers dishes such as Wild King Salmon, Alaskan Jumbo Lump Crab Cake, and Jumbo Lump Crab paired with Butter-Broiled Lobster Tail. Sabatini’s Italian Trattoria also brings Alaskan fish into an Italian-style setting.

The Entertainment Has Alaska In Its Bones

This season also features “Candlelight Concert Series: Fire & Ice,” with Alaska singer-songwriters performing in a candlelit setting twice per voyage. This gives the onboard entertainment a stronger sense of place than a generic music night. Returning favorites add a livelier side, including Great Alaskan Lumberjack Show elements with axe-throwing recruits, trivia, and timber-sports storytelling tied to Ketchikan. Select sailings also feature Deadliest Catch captains and crew members sharing Bering Sea crab-fishing stories. The lineup draws from Alaska’s labor, music, weather, and folklore.

Families Get More Than A Pretty View

Younger travelers are getting special attention, not a watered-down version of the adult trip. Glacier Bay Junior Rangers let kids complete activity books, attend presentations, and earn a badge and certificate through a partnership with the National Park Service. Gold Rush Adventures pulls families into a shipwide Klondike-style search, while Great Alaskan Expedition offers youth and teens a three-hour team-based experience across land, sea, and air. As puppies in the Piazza also return on ships visiting Skagway, guests get to see Alaskan Huskies and sled-dog culture.

Après Sea Gives Alaska A Stylish Cooldown

After a long day outside, Princess is adding a dedicated wind-down ritual through Après Sea. The setup is inspired by après-ski culture. Guests can expect warm drinks, happy hour, and panoramic views after they return from exploring. On Star Princess, the experience is in The Dome, and it provides a strong visual setting at the top of the ship. A relaxed lounge concept gives the evening its own personality, and guests don’t have to jump straight from adventure into dinner.

MedallionClass Keeps The Whole Trip Moving Smoothly

Alaska days can get busy fast, with early excursions, glacier viewing, dinner plans, family meetups, and plenty of time spent moving around the ship. The Princess Medallion Class setup helps cut down on small hassles. The wearable Medallion supports contactless boarding, keyless stateroom entry, onboard ordering, contactless payment, ship navigation, and locating travel companions through the app. When the day already includes ports, wildlife, ice, and dinner reservations, fewer friction points onboard can make a real difference.

Rachel Feltman: Happy Monday, listeners! For Scientific American’s Science Quickly, I’m Rachel Feltman. Let’s kick off the week with a quick roundup of some science news you may have missed.

First, you may have seen some headlines last week about an outbreak of hantavirus on a cruise ship. Here to tell us more about what happened is Tanya Lewis, SciAm’s senior desk editor for health and medicine.

Tanya, thanks so much for coming on to walk us through this.

Tanya Lewis: Yeah, no, thanks so much for having me.

Feltman: Why are we talking about hantavirus and this cruise ship? What happened?

Lewis: Just to catch people up, this outbreak was first noticed about a week ago on a ship called the MV Hondius, which was a cruise ship departing from South America, Argentina. And the people that were sickened and unfortunately passed away, two of those individuals were a married couple who had been traveling—it was a Dutch couple—we think were infected in Argentina and then boarded the ship. And then subsequently, multiple other people have been infected. As of May 7 the number of people on this cruise ship who had been infected with hantavirus was eight people. So that probably could still change.

But you might not have heard of hantavirus before, but it is a virus family that people have been sickened with before, and it’s generally spread by rodents, like rats or mice. And this commonly happens in places where people are exposed to the feces of these animals.

And it causes pretty severe disease. It can cause anything from respiratory distress and fluid in the lungs to some forms of it can be more of, like, a hemorrhagic fever, kind of like Ebola. But the kind that we’re seeing on this cruise ship is more the respiratory kind.

But yeah, this is a virus that, while it is fairly rare to be infected with it, it’s quite lethal. The estimates of its lethality vary, but anywhere from, like, 30 percent to even 50 percent of people infected have died of it.

Feltman: Right, well, and like you said, it, it’s usually spread through rodent feces. But unfortunately, the specific virus we’re talking about, with regard to this cruise ship, is one of the rare instances where it is technically possible to spread from human to human. Can you tell us a little bit more about that?

Lewis: Basically, these individuals on the ship were thought to be infected by human-to-human transmission. At least, that’s the working hypothesis right now. And the reason has to do with the exposure routes.

As I mentioned two of the people were a married couple, so we’re talking about, like, very close contact. This is not something like SARS-CoV-2, the virus that causes COVID, where it’s, like, in the air and wafting around for hours or something. This is something that you would probably need to be, like, breathing very closely, in the same space. And of course, cruise ships are, like, kind of the perfect petri dish for that.

Feltman: Yeah.

So I think there are two things to talk about. There’s, one, why experts are not immediately super concerned about pandemic potential from this specific thing, but also why it is reasonable that I think so many of us, when seeing this news, went, “Uh-oh. We’re—this is a reminder of public-health paradigms I do not wanna be reminded of.”

So let’s start with the good news: Why are experts not freaking out about this?

Lewis: Yeah, so we have to remember that this is a virus that is very different than a lot of the pathogens that have caused respiratory pandemics in the past. In order for a pathogen to be a major pandemic concern, it needs to be very transmissible, and that is something that we have not yet seen with this hantavirus.

I should say, this particular strain is the only strain that has been shown to transmit human to human; it’s called the Andes strain. Most hantaviruses are not thought to spread that way. So the good news is, it’s kind of rare. The bad news, maybe, is that it does appear to have spread, at least, you know, in a limited way, between people.

But yeah, in terms of why experts are not, like, immediately concerned that this will spark a larger epidemic, I think the reason is just that this type of virus and the way it spreads is not conducive, as far as we know, to that type of outbreak. And it’s also happening in a very contained space, so although there have been reports that several of the people on board the ship have disembarked and we are still following that closely, at this point there is no indication of wider community spread, which is what we call it when people are getting infected who have not had direct exposure to the infected individuals.

Feltman: Is there any concern that the time that this virus spent, you know, in such a perfect petri dish may have given it the opportunity to mutate and be better at jumping from person to person?

Lewis: I think what virologists would tell you is, like, the more opportunities a virus has to jump between people, the higher the risk of it developing, like, a concerning mutation that makes it more transmissible.

That said, we’re still talking about a relatively small number of individuals. I mean, eight people sounds like a lot, but, you know, when you’re talking about this being very close quarters on a ship, this is not like, oh, you’re walking into a giant city like New York City and infecting everyone around you or something. So I think that is a little bit reassuring, perhaps, at this point.

But that said, we’ve been humbled before, and I think if there’s one lesson we can take from the COVID pandemic, it’s that we shouldn’t panic, but we should definitely pay attention. And at least scientists wanna know and learn more about this virus and understand it better.

Feltman: I think a lot of people are getting a little freaked out by this news. [Laughs.]

Lewis: Yeah, and I mean, I would be the first to say, like, something like this you hear about, it’s, like, instantly puts you back in that fearful space of 2020. And of course, there was the famous cruise ship, the Diamond Princess, where some of the early COVID cases happened. So that is always concerning.

On the other hand, you know, we have to sort of put it in perspective and remember this is a rare virus and it is something that people have been infected with in the past, so it’s not a completely new virus, unlike SARS-CoV-2, which we had never seen before. So we do have some idea of how this virus works, and while we don’t have any specific treatments for it, we do at least have experts who study it. So that should hopefully give some reassurance that, like, this is not a complete unknown. We are not starting from square one.

Feltman: Thanks for that, Tanya.

Now, listeners, keep in mind we had this conversation on Thursday, May 7. But you can always go to ScientificAmerican.com for more up-to-date science news.

Now for new research on micro- and nanoplastics—but this isn’t the health story you might be expecting. According to a study published last Monday in Nature Climate Change, these tiny bits of broken-down plastic could be contributing to our planet’s warming temperatures.

For starters, just in case you are blissfully unaware: yes, there are, unfortunately, microplastics in the sky. According to a study published in 2021, some of these particles swirl up into the air from the road, where tires and brakes frequently shed small pieces of plastic.

Now, the idea of microplastics permeating the air and even seeding clouds into existence is creepy enough, in my opinion. But this new study suggests they can also have a warming effect on the atmosphere.

Here’s how that would work: if you’ve ever spent time on a patch of blacktop on a sunny summer day, you know that black material absorbs heat. Conversely, white material reflects heat. The same thing happens when you scatter bits of dark and light plastic into the atmosphere, which is what humanity has inadvertently done quite a bit over the past few decades.

Unfortunately, according to this new study, any cooling effects we might get from light microplastics are probably vastly outweighed by the warming effects of dark microplastics. While the estimated effect is a small percentage of the warming fueled by soot from coal power plants, the results are still worrying.

As Jackie Flynn Mogenson reported for SciAm last week, we don’t actually know the concentration of micro- and nanoplastics currently in our atmosphere. But the authors of the new study argue that global climate assessments should do more to factor in these tiny plastic bits. And their findings serve as a great reminder that when we talk about the downsides of plastic, we should recognize that there may be impacts far less concrete and obvious than creating growing piles of trash in landfills.

Now I’ll turn the mic over briefly to SciAm’s chief newsletter editor, Andrea Gawrylewski. She’s gonna tell us about the science behind a tsunami that caught Alaska by surprise.

Andrea Gawrylewski: Thanks, Rachel.

Last summer, in August, a small cruise boat called the David B spent the night in an inlet about 50 miles from Juneau, Alaska. They were supposed to be at anchor nearer to Juneau in this beautiful fjord called Tracy Arm, but bad weather had forced them to pick another place to stay. And it turns out that detour may have saved their lives.

In the morning, from where they were anchored, the boat’s owners noticed seawater rolling over the nearby [sandbar] and shoreline. It was weird because the tide was supposed to be out at that time, and they had no idea why the water was so high.

When scientists heard about the strange sea-level rise, they began examining seismic data, they looked at aerial footage and satellite images, and determined that a massive landslide had occurred at the top of the Tracy Arm fjord.

So what had happened?

The South Sawyer Glacier at the top of Tracy Arm has been steadily shrinking and retreating for the last 25 years. In the spring and summer of last year the ice retreated inland several hundred feet, exposing so much bare rock that it ultimately caused a landslide.

That big slide hit the water and sent a tsunami racing through the fjord—like, so much water that the tsunami surged more than 1,500 feet up the sides of the fjord and sloshed back and forth, like in a bathtub.

That event also produced a seismic signal equivalent to a magnitude 5.4 earthquake. Scientists found smaller seismic events in the data that had occurred at least 24 hours before the big one, and they were increasing exponentially in intensity in the six hours before the landslide.

So now the question is: Could these early seismic signals be used as a warning system? One scientist at the Alaska Earthquake Center has been testing a landslide detection algorithm, and so far it’s detected 35 landslides in near real time. Sending out warnings within three to four minutes of big events could make all the difference to people who live in the area, so scientists are working to improve tools like these.

As former mayors of Anchorage, we each had the responsibility of leading Alaska’s largest city through moments of challenge and opportunity. While our administrations differed in time and approach, one priority remained constant: ensuring that Anchorage and Alaska have access to reliable, affordable energy.

Energy keeps our homes warm through long winters, powers our schools and hospitals, and fuels the businesses that employ our neighbors. It literally fuels every aspect of our economy and our quality of life. When energy becomes uncertain or unaffordable, the consequences are felt immediately by families, employers and communities across the state.

Today, Alaska faces a generational energy challenge. Cook Inlet natural gas production has been declining for decades. Like the frog in a pot on the stove, the problem around us has slowly grown but is about to reach a raging boil. Declining supplies of inexpensive Cook Inlet gas, rising demand and a lack of long-term certainty jeopardize the stability we rely on. Without action — right now — we will lose control over energy costs and availability.

We have faced moments like this before. During his tenure as mayor, Dan Sullivan recognized early the urgency created by declining Cook Inlet gas production. He convened an Energy Task Force that brought together industry leaders, policymakers and stakeholders to confront the issue directly. That work helped lay the foundation for the Cook Inlet Recovery Act, which the Legislature passed quickly to spur new investment and extend the life of the basin. It showed what is possible when Alaska acts with focus and urgency. It also showed the legislature can move fast when aligned on policy.

This is not a new conversation. For years, studies commissioned by both the Alaska Legislature and multiple administrations have identified the need to modernize Alaska’s tax structure and energy policies to remain competitive for large-scale investment and infrastructure projects. Again and again, those reviews reached the same conclusion: If Alaska wants to attract and keep transformational projects, the state must provide a stable, competitive framework that reflects the realities of modern energy development.

The Alaska LNG project is the only viable path to meet that need. It would deliver a stable, long-term supply of natural gas to Southcentral Alaska, helping ensure that homes, schools and businesses have dependable energy at predictable prices. It would also create jobs, strengthen the economy and generate revenue that supports essential public services.

For Anchorage and the entire Southcentral region, the stakes could not be higher. As the economic center of the state, Anchorage depends on dependable energy to sustain growth and opportunity. Utilities, employers and families all need certainty to plan ahead.

If the Legislature fails to pass meaningful property tax reform for Alaska LNG, this opportunity will slip away like other projects have done. Alaska’s property tax system was not designed for a megaproject like Alaska LNG. Because of that, tax reform legislation was introduced in March that will lower our energy bills and speed the delivery of natural gas from the North Slope. Our legislators must act quickly on a targeted solution and avoid making changes that raise energy costs or slow this project. Otherwise, Anchorage and all Southcentral Alaska will be forced to rely on imported gas for decades.

That outcome exposes us to higher and more volatile costs, shrinks our economy, prevents job growth and sends billions of dollars out of state.

Every day of delay increases that risk. As our electric and gas bills made clear this winter, costs are already rising. Without fast action, consumers should be prepared for increases of 30% to 40% or more. Our state will become an even harder place to start a family or a business.

A project of this scale requires careful consideration and responsible decision-making. But waiting carries its own consequences. The longer Alaska delays, the fewer options remain and the more expensive those options become.

As former mayors of Anchorage, we each had unique approaches to problem-solving. But now we speak with one voice: State leaders and legislators must act with urgency and purpose to enact tax changes that propel this project and unlock the revenue, economic, energy security and other benefits from our North Slope natural gas. Decisions now will shape the state’s economic future for generations.
