“Looking Under Venus’s Hood” –Was There Early Life on Earth’s ‘Twin’?

 

Venus Planet

 

Was Venus the first habitable planet in the Solar System? “Venus is like the control case for Earth,” said planetary scientist Sue Smrekar with NASA’s Jet Propulsion Laboratory in 2019, about research suggesting that Venus might have looked like Earth for three billion years, with vast oceans that could have been friendly to life. “We believe they started out with the same composition, the same water and carbon dioxide. And they’ve gone down two completely different paths. So why? What are the key forces responsible for the differences?”

"Unknown" --Four Never-Before-Seen Circular Objects Detected in Cosmos

 

Invisible radio signals from the cosmos have revealed previously unknown phenomena from prebiotic molecules in a starburst about 250 million light-years from Earth to the true rotation of Mercury. But the most famous occurred on August 6, 1967, when a squiggly stretch of high-speed recordings occupying less than a quarter-inch of astronomer Jocelyn Bell Burnell’s radio-telescope readouts revealed the first sign of something strange — an unknown cosmic mystery.

Beyond Comprehension –“Neutron Star’s Superfluid, Superconducting Core at Supranuclear Densities”

Neutron Star

 

Neutron stars are an end state of stellar evolution, says astrophysicist Paul Lasky, at Australia’s Monash University and OzGrav. “They consist of the densest observable matter in the universe, under conditions that are impossible to produce in the laboratory, and theoretical modeling of the matter requires extrapolation by many orders of magnitude beyond the point where nuclear physics is well understood.”

“Are We a Second Genesis?” — Earth’s Hidden Alien Life

"Are We a Second Genesis?" -- Earth's Ancient, Hidden Alien Life

 

Has life started many times of Earth? Could life as we know it today on our pale blue dot in fact be a second genesis? Could Earth’s original microbial life have formed four billion years ago, only to be destroyed some ten million years later during the age of Late Heavy Bombardment by massive asteroids sterilizing the planet? But perhaps some of this primordial “life as we don’t it” survived the 200-million-year barrage of huge objects followed by a second genesis of microbial life representing our form of life co-existing to this day with a “shadow biosphere” of Earth’s original alien life forms.

A Vast Alien Star Stream –“Unveiled Near the Sun”

Milky Way Galaxy

 

Nyx, a vast new stellar stream discovered in the vicinity of the Sun, named after the Greek goddess of the night, may provide the first indication that a dwarf galaxy had merged with the Milky Way disk. These stellar streams are thought to be globular clusters or dwarf galaxies that have been stretched out along its orbit by tidal forces before being completely disrupted.

“The ‘Big Bang’ iPhone” –Age of Sun-Like Stars Predicts Lithium Production

"The Big Bang iPhone" --Age of Sun-Like Stars Predicts Lithium Production

 

“Our observations show that Sun-like stars actually create lithium later in their lives, after they have swelled to become red giants. This means that the Sun itself will also manufacture lithium about five billion years in the future,” said Dr. Yerra Bharat Kumar from National Astronomical Observatories of the Chinese Academy of Sciences about the “lithium-rich” red giants first discovered about 40 years ago that create up to 1,000 times as much lithium as other giant stars. Yet how they create their lithium remains a mystery. The amount of lithium produced in just one of these giants would be enough to make electric car batteries for 20,000 trillion cars.
