The Houston Astros were established as the Houston Colt .45s in 1962. They changed to their current name three years later, when they moved into the iconic Astrodome, the world’s first domed sports stadium. The name references Houston’s role as the center of the U.S. astronaut program. The Astros are the oldest MLB franchise to have never won the World Series while remaining in the same city over their history. After heart-breaking playoff losses in 1980, 1981, and 1986, and more playoff appearances in the late 1990s and early 2000s, the Astros finally appeared in their first and (to date) only World Series, in 2005 against the Chicago White Sox.
