This is insanely cool. New radar scans point to the strong possibility of another room behind King Tut’s tomb. One theory suggests that it could be the lost tomb of the famous Queen Nefertiti.

“[…] the Egyptian antiquities minister held a press conference
in Cairo to announce a tantalizing new piece of evidence: 
Radar scans on those walls have revealed not only the 
presence of hidden chambers, but also unidentified objects 
that lie within these rooms. These objects, he said, 
seem to be composed of both metal and organic materials.”
