We keep looking for aliens — but are aliens looking for us?


Could extraterrestrials find life on Earth? The question of whether or not life exists on other worlds suggests pondering if extraterrestrial beings might be able to find life on our home world. More than 4,500 exoplanets are currently known to astronomers, many of which were found as they orbited in front of their parent star as seen from Earth, dimming light from the stellar surface. “Let’s reverse the viewpoint to that of other stars and ask from which vantage point other observers could find Earth as a transiting planet,” Lisa Kaltenegger, associate professor of astronomy at Cornell University’s Carl Sagan…

However, Swiss startup Transmutex wants to reinvent nuclear energy using a lesser-known element called thorium.  Uranium’s forgotten cousin Thorium is a lead-like metal that is mildly reactive, but four times more abundant than uranium and a lot safer to handle.
