At least 1,715 nearby star systems sat at a perfect angle to view Earth during the past 5,000 years, meaning aliens living in those systems, if they exist and have the right technology, could have watched our planet from afar as early human civilizations first emerged. Of those star systems, 313 exited the special viewing zone, known as the Earth transit zone (ETZ), sometime in the past few thousand years, leaving 1,402 star systems capable of providing a glimpse of our planet today, according to a new study, published Wednesday (June 23) in the journal Nature. And over the next … Read more

This energy-harvesting technology could leave traces just outside a spinning black hole’s event horizon — the boundary beyond which a black hole’s gravity becomes too strong for matter and energy to escape. And the process could explain at least some flares of plasma, a white-hot form of charged gas, that scientists have already detected near these massive disruptions in time and space. a new study published Jan. 13 in the journal Physical Review D proposes. And while it’s only a … Read more

Failure to detect and contain a deadly virus early enough to prevent an outbreak is a key component of the story in AMC’s sci-fi series “Fear the Walking Dead” (which airs on Sundays at 9 p.m. EDT/8 p.m. CDT, starting Aug. 12). The show, now in its … Read more
