A painting may have started another royal controversy. Commissioned by the palace, a portrait of Queen Elizabeth to mark her 60 years on the throne was created by contemporary portraitist Nicky Philipps. However, critics say it doesn't resemble her. Some see Margaret Thatcher, or perhaps a hint of Winston Churchill. At best, it looks like a distant foreign relative but not the queen, herself. Like it or not, that picture will now go on a new stamp to be used across Britain.

A new clue has emerged in the mystery of Amelia Earhart, the fearless aviator who disappeared over the Pacific Ocean in 1937. For nearly 80 years, experts have searched those waters for remnants of her plane, and now they believe they've found it. Sonar images of the waters where her plane is believed to have gone down show a shadow, a white line, that scientists believe is her plane. Resting on a reef roughly 600 feet below the water's surface, it appears man-made, and at 32 feet it is a similar length to Earhart's 38-foot-long plane, the Electra. The location of the potential crash site is near the Pacific island of Nikumaroro, where scientists believe Earhart and her co-pilot died as castaways.
