In Disney’s ‘Moana,’ the characters navigate using the stars, just like real Polynesian explorers − an astronomer explains how these methods work
If you have visited an island like one of the Hawaiian Islands, Tahiti or Easter Island, also known as Rapa Nui, you may have noticed how small these land masses appear against the vast Pacific Ocean. If you’re on Hawaii, the nearest island to you is more than 1,000 miles (1,600 kilometers) away, and the coast of the continental United States is more than 2,000 miles (3,200 kilometers) away. To say these islands are secluded is an understatement.
For me, watching the movie “Moana” in 2016 was eye-opening. I knew that Polynesian people traveled between a number of Pacific islands, but seeing Moana set sail on a canoe made me realize exactly how small those boats are compared with what must have seemed like an endless ocean. Yet our fictional hero went on this journey anyway, like the countless real-life Polynesian voyagers upon which she is based.
As an astronomer, I have been teaching college students and visitors to our planetarium how to find stars in our sky for more than 20 years. As part of teaching appreciation for the beauty of the sky and the stars, I want to help people understand that if you know the stars well, you can never get lost.
U.S. Navy veterans learned the stars in their navigation courses, and European cultures used the stars to navigate, but the techniques of Polynesian wayfinding shown in Moana brought these ideas to a very wide audience.
The movie Moana gave me a new hook – pun not intended – for my planetarium shows and lessons on how to locate objects in the night sky. With “Moana 2” out now, I am excited to see even more astronomy on the big screen and to figure out how I can build new lessons using the ideas in the movie.
The North Star
Have you ever found the North Star, Polaris, in your sky? I try to spot it every time I am out observing, and I teach visitors at my shows to use the “pointer stars” in the bowl of the Big Dipper to find it. These two stars in the Big Dipper point you directly to Polaris.
If you are facing Polaris, then you know you are facing north. Polaris is special because it is almost directly above Earth’s North Pole, and so everyone north of the equator can see it year-round in exactly the same spot in their sky.
It’s a key star for navigation because if you measure its height above your horizon, that tells you how far you are north of Earth’s equator. For the large number of people who live near 40 degrees north of the equator, you will see Polaris about 40 degrees above your horizon.
If you live in northern Canada, Polaris will appear higher in your sky, and if you live closer to the equator, Polaris will appear closer to the horizon. The other stars and constellations come and go with the seasons, though, so what you see opposite Polaris in the sky will change every month. https://www.youtube.com/embed/COHwfKusGbs?wmode=transparent&start=0 Look for the Big Dipper to find the North Star, Polaris.
You can use all of the stars to navigate, but to do that you need to know where to find them on every night of the year and at every hour of the night. So, navigating with stars other than Polaris is more complicated to learn.
Maui’s fishhook
At the end of June, around 11 p.m., a bright red star might catch your eye if you look directly opposite from Polaris. This is the star Antares, and it is the brightest star in the constellation Scorpius, the Scorpion.
If you are a “Moana” fan like me and the others in my family, though, you may know this group of stars by a different name – Maui’s fishhook.
If you are in the Northern Hemisphere, Scorpius may not fully appear above your horizon, but if you are on a Polynesian island, you should see all of the constellation rising in the southeast, hitting its highest point in the sky when it is due south, and setting in the southwest.
Astronomers and navigators can measure latitude using the height of the stars, which Maui and Moana did in the movie using their hands as measuring tools.
The easiest way to do this is to figure out how high Polaris is above your horizon. If you can’t see it at all, you must be south of the equator, but if you see Polaris 5 degrees (the width of three fingers at arm’s length) or 10 degrees above your horizon (the width of your full fist held at arm’s length), then you are 5 degrees or 10 degrees north of the equator.
The other stars, like those in Maui’s fishhook, will appear to rise, set and hit their highest point at different locations in the sky depending on where you are on the Earth.
Polynesian navigators memorized where these stars would appear in the sky from the different islands they sailed between, and so by looking for those stars in the sky at night, they could determine which direction to sail and for how long to travel across the ocean.
Today, most people just pull out their phones and use the built-in GPS as a guide. Ever since “Moana” was in theaters, I see a completely different reaction to my planetarium talks about using the stars for navigation. By accurately showing how Polynesian navigators used the stars to sail across the ocean, Moana helps even those of us who have never sailed at night to understand the methods of celestial navigation.
The first “Moana” movie came out when my son was 3 years old, and he took an instant liking to the songs, the story and the scenery. There are many jokes about parents who dread having to watch a child’s favorite over and over again, but in my case, I fell in love with the movie too.
Since then, I have wanted to thank the storytellers who made this movie for being so careful to show the astronomy of navigation correctly. I also appreciated that they showed how Polynesian voyagers used the stars and other clues, such as ocean currents, to sail across the huge Pacific Ocean and land safely on a very small island thousands of miles from their home.

(Family Features) For some, tax season represents the opportunity for a return and some much-needed relief for their bank accounts. Yet for others, it’s time to write a check to Uncle Sam. Ensure you’re up to date on all things 2025 taxes with this guidance from the Consumer Financial Protection Bureau and the IRS.
Tax Deadlines
If you’re unable to file before the traditional April 15 deadline, you do have a few options. Filing for an extension provides an extra six months until Oct. 15, however, if you believe you will owe taxes, you’re required to estimate how much you owe and pay that amount alongside your extension form.
Filing Your Taxes
Each person’s tax situation is unique, but there is an assortment of options when it comes time to file. Some people (an estimated 100 million) are eligible to file their returns for free, such as seniors, those who speak English as a second language, those with incomes of less than $60,000, servicemembers and more. Be sure to check your eligibility for services like IRS Volunteer Income Tax Assistance, AARP Foundation Tax-Aide, The Tax Counseling for the Elderly, MyFreeTaxes, GetYourRefund, IRS Free File, MilTax and more.
Accessing Your Refund
Electronically filing and choosing direct deposit is the fastest way to receive your refund. The IRS typically issues refunds within 21 days, but issuance of a paper check may take 4-6 weeks. Make sure to have your account and routing numbers ready when filing your return. One alternate solution is to have your refund issued to a prepaid card that accepts direct deposit, but there may be fees involved. Check with the card provider to determine any applicable fees.
Watch for Scams
The IRS will not contact you by email, text message or social media to request personal or financial information. Scammers may impersonate the IRS to convince you to share personal information through the mail, telephone, email and beyond.

The Controversy Surrounding the Jackie Robinson Biography at the U.S. Naval Academy
The Trump administration’s push to ban Jackie Robinson’s biography from the U.S. Naval Academy Library highlights tensions over diversity narratives in education, sparking controversy and raising concerns about historical representation amid ongoing political divisiveness.
Jackie Robinson, first baseman with the Brooklyn Dodgers, circa 1949.
In an alarming move reflecting ongoing tensions over diverse narratives in education and public discourse, the Trump administration is reportedly pushing to ban a biography of Jackie Robinson from the Nimitz Library at the U.S. Naval Academy. This follows a week of controversy sparked by the temporary removal and subsequent restoration of an article on Robinson’s Army service from the Pentagon’s website.
According to a report from The New York Times, Defense Secretary Pete Hegseth has directed the Naval Academy to review its library collection for works that embody themes of diversity, equity, and inclusion. The biography of Robinson, alongside around 900 other titles—including Martin Luther King Jr.’s autobiography and “Einstein on Race and Racism”—has been flagged for removal under this directive.
Cmdr. Tim Hawkins, a spokesman for the Naval Academy, stated, “The U.S. Naval Academy is fully committed to executing and implementing all directives outlined in executive orders issued by the president and is currently reviewing the Nimitz Library collection to ensure compliance. The Navy is carrying out these actions with utmost professionalism, efficiency, and in alignment with national security objectives.”
With Hegseth scheduled to visit the Academy soon, it remains uncertain whether these controversial titles will be removed from the library before his arrival. The issue has sparked substantial outcry, particularly in light of the administration’s recent criticism over removing articles that celebrate influential figures in U.S. history, like Robinson and the Navajo code talkers.
In a discussion prompted by ESPN’s Jeff Passan, Pentagon press secretary John Ullyot reiterated the administration’s stance against diversity initiatives, indicating that some content may have been removed inadvertently. His comments drew significant backlash, leading to a follow-up statement emphasizing “patriotism and dedication to the warfighting mission” rather than racial or ethnic identities.
Robinson, a second lieutenant in the Army from 1942 to 1944, served with the 761st Tank Battalion, the first Black tank unit to see combat in World War II. His court-martial for refusing to adhere to a racist bus policy only underscores his enduring struggle against racial injustice, paving the way for his groundbreaking success in Major League Baseball as he broke the color barrier.
The Los Angeles Dodgers, Robinson’s team for a decade, are scheduled to visit President Trump at the White House to celebrate their 2024 World Series title this April, coinciding with Jackie Robinson Day. This timing juxtaposes their celebration of his legacy against the backdrop of an administration taking steps to diminish recognition of such key figures in American history.
As this situation unfolds, it raises critical questions about the role of educational institutions, historical representation, and the importance of equitable narratives in our national dialogue. In today’s divided political landscape, the removal of influential and diverse voices from public access can serve not just as a reflection of current priorities but also as a forewarning about the future of discourse surrounding diversity and inclusion in America.
