Hidden for 1,500 years, this funeral tomb in Palenque, Mexico, was finally glimpsed by human eyes when researchers lowered a mini camera (measuring 4 x 6cm) through a crack in the ceiling.
After 12 years of knowing the tomb existed, it would've been bloody—pardon the pun—satisfying to finally clap eyes on what lay inside. Not that they can locate the bones of the Mayan ruler however, as the camera can't see that far, nor can the team of researchers squeeze inside for a proper look, due to fears of structural damage. I suppose in another 12 years' time the same researchers will be able to despatch a little robot through the very same crack for a thorough exploration. [National Geographic via Neatorama]
