“Extraterrestrial” –Solar System Dynamics Triggered Earth’s Plate Tectonics

Asteroid Impact

 

“It is remarkable to think that our oldest animal ancestors—and therefore all of us—may owe our existence, in part, to an unusual episode of plate tectonics over half a billion years ago” said Tim Lenton, professor of Climate Change and Earth System Science with the University of Exeter’s Global Systems Institute in June, 2019 about the most dramatic moment in the history of evolution when the spectacular supernova of biology, the Cambrian Explosion, was detonated and the world of animal life was born with the rise in oxygen levels during the formation of the supercontinent Gondwana and a major increase in continental arc volcanism—chains of volcanoes often thousands of miles long formed where continental and oceanic tectonic plates collided.

The Oumuamua Paradox –“We Have Slim Chance of Distinguishing ET Artifacts from Natural Celestial Objects”

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 computer- 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.

Ancient Antarctica Ice –“Foreshadows Carbon Dioxide Levels Not Seen in 2 Million Years”

 

Antarctica Ice-Core Station

 

“We’re in a different situation now — carbon dioxide is the major player in our current world,” said Princeton University geophysicist Yuzhen Yan, lead author of a new climate-change study based on two- million-year-old ice cores from Antarctica. “If we want to look into the geologic past for an analogy of what’s going on in our world today, we need to go beyond 2 million years to find it.”

“Three Supermassive Monsters” –Discovered At Core of an Odd Galaxy

NGC 6240

 

Like an ancient mythological beast, an international research team led by scientists from Göttingen and Potsdam proved for the first time that the irregular galaxy NGC 6240 contains three supermassive black holes. The observations (above)  show the black holes close to each other in the core of the galaxy. The study points to simultaneous merging processes during the formation of the largest galaxies in the universe.

“99.999% of the Speed of Light” –Gamma Ray Explosion With Highest Energy Ever Observed

Gamma Ray Burst

 

“Scientists have been trying to observe very-high-energy emission from gamma-ray bursts for a long time,” explained lead author Antonio de Ugarte Postigo of the Instituto de Astrofísica de Andalucía in Spain about new observations from the NASA/ESA Hubble Space of the gamma-ray burst GRB 190114C. “This new observation is a vital step forward in our understanding of gamma-ray bursts, their immediate surroundings, and just how matter behaves when it is moving at 99.999% of the speed of light.”

“Iconic!” –New Image of the Milky Way’s Center: Black Hole, Colossal Magnetic Fields, Supernovas

Milky Way Center

 

Humanity now has an image of the Milky Way’s violent center similar in importance to the Event Horizon Telescope (EHT) image of Galaxy M87’s gargantuan black hole. The image (above) shows the new view of our galactic center from the Murchison Widefield Array, with the lowest frequencies in red, middle frequencies in green, and the highest frequencies in blue. Huge golden filaments indicate enormous magnetic fields, supernova remnants are visible as little spherical bubbles, and regions of massive star formation show up in blue. The supermassive black hole at the center of our galaxy is hidden in the bright white region in the center.
