Magellan's expedition was the first to successfully sail around the whole world (although only 18 out of 257 managed to return, and Magellan himself got killed on the way), and quite a few places and animals they found were previously unknown to Europeans.
Among other things, Magellan discovered the Strait of Magellan, which runs between the Atlantic and the Pacific near the southern tip of South America, and a species of penguin called the Magellanic Penguin.
His expedition also established the need for the international date line, you could say he discovered that.
Among things he did NOT discover - he found them early but was not the first European to do so - are:
Although Ferdinand Magellan discovered and named the Pacific Ocean, he did not discover any part of Australia.
