Io, Jupiter’s Exploding Moon: Unique in the Milky Way?

Jupiter's moon Io

 

In February 2001, an eruption from the Surt volcano on the hellscape of Jupiter’s moon, Io, the volcanic epi-center of our solar system, exploded with an estimated output of an almost incomprehensible 78,000 gigawatts. By comparison, the 1992 eruption of Mount Etna, Sicily, was estimated at 12 gigawatts. During its peak, observed by the WM Keck II Telescope on Hawaii, its output almost matched the eruptive power of all of Io’s active volcanoes combined.

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.
