Death of Planet Earth? –“The Sixth Great Extinction is Premature”

6th Mass Extinction

 

In the past 540 million years, the Earth has endured five mass extinction events, each involving processes that upended the normal cycling of carbon through the atmosphere and oceans. These globally fatal perturbations in carbon each unfolded over thousands to millions of years, and are coincident with the widespread extermination of marine species around the world.

Humanity’s First Image of the ‘Galactic Bar’ at Milky Way Center

Milky Way's Galactic Bar

 

“We know the Milky Way has a bar, like other barred spiral galaxies, but so far we only had indirect indications from the motions of stars and gas, or from star counts in infrared surveys. This is the first time that we see the galactic bar in three-dimensional space, based on geometric measurements of stellar distances,” says Gaia astrophysicist Friedrich Anders of the large, elongated distribution of stars: the galactic bar at the center of our galaxy.

“Hubble’s Elusive Constant” –‘Something is Fundamentally Flawed’

 

Expanding Universe Hubbles Cosntant

 

Scientists have known for almost a century that the universe is expanding, meaning the distance between galaxies across the universe is becoming ever more vast every second. But exactly how fast space is stretching, a value known as the Hubble constant, has remained stubbornly elusive. Several recent studies that point to a nagging discrepancy between modern expansion measurements and predictions based on the universe as it was more than 13 billion years ago, as measured by the European Space Agency’s Planck satellite.

Unknown Phenomena –“Repeating FRB’s Formed by Events Never Seen Before”

 

Fast Radio Burst

 

The mystery of FRB’s deepens: many of the brightest, weirdest phenomena in space come from cataclysmic events like explosions or collisions. But many fast radio bursts (FRBs), milliseconds-long bursts of powerful radio waves that come from the depths of space have been attributed to many different sources, from neutron star mergers to alien spaceships. But so far, no explanation seems plausible.

“Planet B” –NASA’s Plans for Making Mars a Refuge for Homo Sapiens

NASA Terraformed Mars

 

“Mars is the most habitable planet in our Solar System besides Earth,” said Laura Kerber, Research Scientist at NASA’s Jet Propulsion Laboratory  research scientist at JPL with interests in  the ancient Martian climate and extraterrestrial environments. “But it remains a hostile world for many kinds of life. A system for creating small islands of habitability would allow us to transform Mars in a controlled and scalable way.”

“The Central Mystery of Our Age” –World’s Scientists Struggle to Define a Black Hole

M87 Black Hole

 

On Feb. 14, 1990, the Voyager 1 spacecraft looked back at our solar system and snapped the first-ever pictures of the planets from its perch at that time beyond Neptune. This past April, the Event Horizon Telescope (EHT) team unveiled humanity’s first image of a supermassive black hole –described as the Gates of Hell and the End of Spacetime– the picture of galaxy Messier 87’s central supermassive black hole. A monster the size of our solar system, and bigger, with the mass of six and a half billion suns, with a ring of gas—in hues of red, orange, and yellow—glowing around it, the shadow cast by the event horizon, predicted by Einstein’s theory of general relativity.
