Question: When was the last time the pittsburgh steelers went to the super bowl?

Disambiguated questions and answers:
context: On January 7, 2007, Cowher resigned from coaching the Steelers, citing a need to spend more time with his family. He did not use the term "retire", leaving open a possible return to the NFL as coach of another team. A three-man committee consisting of Art Rooney II, Dan Rooney, and Kevin Colbert was set up to conduct interviews for the head coaching vacancy. The candidates interviewed included: offensive coordinator Ken Whisenhunt, offensive line coach Russ Grimm, former offensive coordinator Chan Gailey, Minnesota Vikings defensive coordinator Mike Tomlin, and Chicago Bears defensive coordinator Ron Rivera. On January 22, 2007, Mike Tomlin was announced as Cowher's successor as head coach. Tomlin is the first African-American to be named head coach of the Pittsburgh Steelers in its 75-year history. Tomlin became the third consecutive Steelers Head Coach to go to the Super Bowl, equaling the Dallas Cowboys (Tom Landry, Jimmy Johnson and Barry Switzer) in this achievement. He was named the Motorola 2008 Coach of the Year. On February 1, 2009, Tomlin led the Steelers to their second Super Bowl of this decade, and went on to win 27–23 against the Arizona Cardinals. At age 36, he was the youngest head coach to ever win the Super Bowl, and he is only the second African-American coach to ever win the Super Bowl (Tony Dungy was the first). The 2010 season made Tomlin the only coach to reach the Super Bowl twice before the age of 40. Tomlin led the team to his second Super Bowl (Super Bowl XLV) on February 6, 2011. However, the Steelers were defeated in their eighth Super Bowl appearance by the Green Bay Packers by the score of 31–25. The Steelers recorded their 400th victory in 2012 after defeating the Washington Redskins.
