Our Pale Blue Dot had a busy news week from remnants of a collision with an alien world found deep within Earth to our imagination might be the core of what human brains evolved to do to the untold story of the world’s biggest nuclear bomb.

 

NASA’s 7-Step plan for how to confirm whether we’ve really found aliens –Anticipating mounting evidence of alien life, and also anticipating that the media might mischaracterize that evidence, NASA’s chief scientist wants to put some guardrails on the story—by placing potential evidence of alien life on a seven-step scale that ranges from interesting to definitive. In a paper published in Nature on October 27, NASA’s James Green proposed a what he described as a “framework for reporting evidence for life beyond Earth”

Eels are guided by Earth’s magnetic field, reports The Economist –“They can tell its strength as well as its direction. From Aristotle to Sigmund Freud, eels’ reproductive habits have puzzled observers of the natural world.

Seti: why extraterrestrial intelligence is more likely to be artificial than biological, writes Martin Rees, Emeritus Professor of Cosmology and Astrophysics, University of Cambridge for The Conversation –“Suppose there are other planets where life began and that it followed something like a Darwinian evolution (which needen’t be the case). Even then, it’s highly unlikely that the progression of intelligence and technology would happen at exactly the same pace as on Earth. But around a star older than the Sun, life could have had a head start of a billion years or more.”

Deep Within Earth — “Remnants of a Collision with an Alien World”, reports Science. “Geologists don’t know much about where these gargantuan, blob-like structures came from or what they are. Although a  new study by researchers from Arizona State University (ASU), argues that they  may represent ancient fragments of the Mars-sized object known as Theia that struck the  early Earth around 4.5 billion years ago, with a huge chunk of Theia and/or possibly Earth fragmenting off, and becoming the Moon we know today.

Why Dragons Dominated the Landscape of Medieval Monsters –The mythical beasts were often cast as agents of the devil or demons in disguise, reports The Smithsonian. ” In the European Middle Ages, monster stories served as religious teaching tools, offering examples of what not to do, manifestations of the threats posed by the supernatural and the diabolical, and metaphors for the evil humans do to one another.”
