* The Hudson River: This is his most famous discovery. He sailed up the river that now bears his name, exploring it for about 150 miles. He was searching for a Northwest Passage to Asia, but instead, he discovered a waterway that led inland, opening up the region for European settlement.
* The New World: While not the first European to reach North America, his explorations gave a more detailed view of the area and its potential. He encountered native tribes and engaged in trade with them.
* The Atlantic Coast: He also explored the Atlantic Coast, charting the coastline and discovering areas like New York Harbor.
* He failed to find a Northwest Passage: Despite his explorations, he never found a passage to Asia, leading to his eventual dismissal by the Dutch East India Company.
It's important to note that Hudson's voyage was not without controversy. His actions towards the Native Americans were often exploitative, and he ended up being abandoned by his crew in the icy waters of Hudson Bay.
