Answer: Ursa Major

If Ursa Major doesn’t sound familiar, you might know this constellation as the Big Dipper. But if we’re being entirely accurate, it’s the Big Dipper plus Polaris (the North Star) that graces Alaska’s state flag. Meant to represent Alaska’s great outdoors heritage, the state flag features a dark blue background with yellow stars. The blue background is said to represent the night sky, the surrounding oceans, and also the forget-me-not, Alaska's state flower. And Polaris’ placement highlights how Alaska is the northernmost state in the Union.

While the St. Petersburg-Tampa Airboat Line folded only four months after it debuted, it transported over 1,200 passengers during its time.

Answer: Humāyūn’s Tomb

No trip to India is complete without a trek to Agra so you can visit the Taj Mahal. While it’s clearly a magnificent structure, many are surprised to learn that there was another mausoleum in India that served as the inspiration for the Taj Mahal, Humāyūn’s Tomb. Located in Delhi, this tomb is considered a pinnacle of Mughal architecture — namely the domes and tilework. Similar styles can be seen in structures across India from this same period, and are prominent features in the Taj Mahal.
