Beyond the Anthropocene -“A Mere Blink of the Geologic Eye”

 

Alien Life

 

The human experience on our Pale Blue Dot “has lasted for less than 10 one-billionths of cosmic history surrounded by vast lifeless space, and yet we are congratulating ourselves on an unearned geological legacy before we’ve proved ourselves capable of escaping the next century with our lives,” says mass-extinction authority, Peter Brannen, author of The Ends of the World. “Human history, though environmentally cataclysmic and sedimentologically interesting, is not usefully described in the terms of a geological epoch on par with a yawning span of time like the Early Cretaceous, an epoch that lasted 600,000 times longer than this newly minted one.”

The Extraterrestrial-Contact Paradox 

ESO Observatories Chile

 

British physicist Stephen Wolfram believes extraterrestrial intelligent life is inevitable, but with a caveat. Although intelligent life is inevitable, we will never find it -at least not by searching in the Milky Way. Wolfram points out that in order to compress more and more information into our communication signals – be they mobile phone conversations or computers – we remove all redundancy or pattern. If anything in a signal repeats, then it can be deleted. But this process of removing any pattern from a signal makes the signal look more and more random – in fact, pretty much like the random radio “noise” that rains down on Earth coming from stars and interstellar gas clouds.

The Death of Mars -Did a Pluto-Size Asteroid Ignite Ancient Climate Change?

 

Mars Planet

 

In the mid-1980s, a group of American archaeologists pored over satellite images trying to understand what had become of the Mayan civilization that had once ruled over Mexico’s Yucatan Peninsula, discovered a pattern: a near-perfect ring of sinkholes -cenotes- about 200 kilometers across, encircling the Yucatecan capital, Merida, and port towns of Sisal and Progreso. A pattern created by an ancient asteroid explosion that one young NASA scientist thought may yield clues to the lost ocean and atmosphere of Mars.

“Magic Islands” –Titan’s Very Weird Lakes

 

Lakes of Saturn's Titan

 

“The more we learn about Titan, the more we learn that we can’t ignore the lakes,” said Kendra Farnsworth, a planetary scientist at the University of Arkansas in Fayetteville and lead author of the new study that explains how bubbles erupt in frigid hydrocarbon lakes on Saturn’s largest moon Titan made up of methane and ethane, potentially creating fizz violent enough to form unusual geologic features.
