- Science
NGC 1499, the California Nebula, is an emission nebula in Perseus whose outline resembles the state. Its low surface brightness makes it difficult to see visually despite its large apparent size.
- Geography
Vespucci's contribution was the interpretation rather than the arrival: he argued the landmass was a continent unknown to Europe. A German mapmaker named it after him in 1507.
