A new discovery involving one of the world's most famous paintings.

It appears Leonardo da Vinci's "Mona Lisa" may have been a second attempt by the artist.

A French scientist took a close look at the painting with modern technology.

According to CNN, he used a multispectral camera to project intense lights on to the painting while measuring the reflections. This helps expose what happened between the paint layers.

He says, there's a painting beneath it that the artist apparently felt wasn't quite as worthy.

CNN reports the hidden picture shows a woman looking into the distance, with no trace of the characteristic smile.

Other da Vinci experts say, it's entirely possible the final painting was a redo, because people who commissioned paintings often asked the artists to make changes.
