“The Guardians?” –Jupiter-Like Exoplanets May Help Foster Earth-like Evolution

"The Guardians" --Jupiter-Like Exoplanets May Help Foster Earth-like Evolution

 

“Historically, our assumption has been that the region around Jupiter is fairly empty, cleaned out by the giant planet’s gravity, but our results teach us that there is a region that is constantly being fed,” said Kathryn Volk at the University of Arizona Lunar and Planetary Laboratory in 2019 about a constant source of new objects that may help explain the surprising rate of icy body impacts with Jupiter, such as the Shoemaker-Levy 9 event in 1994 when over twenty fragments of comet that collided with Jupiter were observed by astronomers at hundreds of observatories around the world.

“Unvisited” –Earth May Exist in a Galaxy of Interstellar Space-Faring Civilizations

"Unvisited" --Earth May Exist in a Galaxy of Interstellar Space-Faring Civilizations (Weekend Feature)

 

This past February, four distinguished astrophysicists —Jonathan Carroll-Nellenback, Adam Frank, Jason Wright, Caleb Scharf— suggested in new research that Earth may have remained unvisited by space-faring civilizations all the while existing in a galaxy of interstellar civilizations seeded by moving stars that spread alien life, offering a solution to the perplexing Fermi paradox. They concluded that a planet-hopping civilization could populate the Milky Way in as little as 650,000 years.

"Wobbling" --Galaxy M87's Black Hole the Size of Our Solar System Unveils a History of the Observable Universe

 

On April 10, 2019 the astronomers at Harvard’s Black Hole Initiative were asking what does the glowing bright orange ring around the now iconic black hole the size of our solar system at the center of the monster elliptical galaxy M87 –the largest, most massive galaxy in the nearby universe–mean? according to Harvard Event Horizon Telescope radio astronomer, Michael Johnson.

“Holy Grail” –Proof of Cosmic Objects Without a Hard Surface Confined Within an Invisible Boundary

Black Holes

 

Albert Einstein described black holes as strange objects “where God divided by zero.” An international team of astrophysicists has now confirmed that black holes are a distinct “species” from neutron stars –comparable to black holes in mass and size but confined within a hard surface, unlike black holes, an exotic cosmic object without a hard surface predicted by Einstein’s theory of General Relativity that do not have a surface, and are confined within an invisible boundary, called an event horizon, from within which nothing, not even light, can escape.
