Violent Neutron Star Collision Discovered Near Earth’s Birthplace (Weekend Feature)

Neutron Star Collision

 

The heaviest natural elements on the periodic table such as gold, platinum, and uranium were forged during the mergers of binary neutron stars. Astronomers have previously estimated that tens of thousands of such binary neutron star mergers must have occurred throughout our Milky Way Galaxy during the past 10 billion years, sprinkling neutron-rich elements throughout the gas that eventually formed the next generation of stars and planets. By studying the composition of meteorites, astronomers now conclude that a single collision of neutron stars occurred shortly before and near to the formation of our solar system, producing a measurable fraction of the heavy elements here on Earth.

Monster Black Hole in Tiny Galaxy Holds Clues to Their Existence in Early Universe

Supermassive Black Hole

 

A big step in solving the mystery of how the very biggest black holes grow has been taken by researchers using NASA’s Chandra X-ray Observatory. They identified a black hole containing about 200,000 times the mass of the Sun, buried in gas and dust in the dwarf galaxy Mrk 462. ”Future sensitive observations, using x-ray and the James Webb Space Telescope (JWST) for example, will be able to find signatures of direct collapse black holes over a wider range of masses and growth rates, and help determine whether they form the seeds of the supermassive black holes we see today,” wrote Dartmouth University astrophysicist Ryan Hickox in an email to The Daily Galaxy,

Venus Could Have Been Habitable and Radically Different from the Planet We See Today

 

Planet Venus

 

“Our models show that there is a real possibility that Venus could have been habitable and radically different from the Venus we see today,” said Michael Way of The Goddard Institute for Space Science about Earth’s ‘twisted sister’ planet. “This opens up all kinds of implications for exoplanets found in what is called the ‘Venus Zone’, which may in fact host liquid water and temperate climates.”
