Archaeology has gone interstellar.
The peculiar behavior of KIC 8462852—a star 1,500 light-years from Earth that is prone to irregular dimming—has prompted widespread speculation on the Internet that it is host to an “alien megastructure,” perhaps a vast array of orbiting solar panels.
Scientists have pointed out various natural, non-alien phenomena that could be causing the stellar light show, but the SETI crowd isn’t taking any chances. Astronomers have begun using a radio telescope, the Allen Telescope Array, to detect possible signals in the vicinity of KIC 8462852.
But, the astronomers might be eavesdropping on a tomb.
