A clip from The Tonight Show with Johnny Carson in 1978 made the social media rounds in mid-July.
The guest that episode-astronomer and science educator Carl Sagan-offered astute criticisms of the then recently released Star Wars film for its myopic imagining of how organisms from other galaxies might look.
In this collection, reporter Leonard David examines the government report published in June that surveys our evidence for extraterrestrial life so far, and two of our opinion writers contemplate some specific circumstances for alien contact.
Sagan's prescient observations remind me that our search for other life in the universe will always be a strictly human endeavor: how we imagine aliens might look, think or operate and how we look for them or detect their existence- all these factors are based on the human framework of perception.
Such limitations will only be problematic if we ignore them and fail to somehow jump beyond the bounds of our minds.
