Ray of light beams off 1 World Trade Center

Exactly one year ago Thursday, sports agent Ben Sturner took a photo of a rainbow over lower Manhattan that went viral.

Fast forward to the same day one year later: Sturner captured another amazing shot from his home. And, once again, the image is being shared around the world.

At 7:11 a.m., Sturner took a photo from his mobile device of a strange beam of light shining from the glass facade of the building that now stands near where the Twin Towers once stood.

Sunday marks the 15th anniversary of 9/11.
