Astronomers Create Largest 3D Map of the Universe
A team of astronomers working with the Sloan Digital Sky Survey (SDSS) created the largest ever three-dimensional map of the universe. Released along with an accompanying study, the astronomers say the new map is the first to exclusively use the positions of quasars to chart the significant structures of the Universe. “Because quasars are so […]
Cosmic Impact May Have Caused Prehistoric ‘Big Freeze’
Scientists say they may have found a link between a dramatic climate shift nearly 13,000 years ago and an asteroid or comet that struck the Canadian province of Quebec. Researchers at Dartmouth College say the comet/asteroid strike took place at the beginning of a global cooling event known as the Younger Dryas stadial or the […]
US, Europe Could Collide to Form Supercontinent
Taking a trip from the United States to Europe might be much easier in 220 million years, according to a recent study, which suggests that’s when the Atlantic Ocean could close up, causing North America to collide with Europe. Australian geologists have detected a new subduction zone–when two oceanic plates collide–forming off the coast of […]
Scientists Discover Universe’s Largest Known Structure
Scientists have found the largest known structure in the universe, a cluster of galactic cores so vast it would take four billion years for a spacecraft traveling at the speed of light to cross it. The sighting challenges a theory from Einstein which suggests such a massive object shouldn’t exist in the universe. A quasar […]
Mystery Properties of Black Holes Revealed
Of all the celestial objects that make up the Universe, nothing is more mysterious than the black hole. Now Denmark scientists have come up with what they say are groundbreaking theories that explain several properties of the enigmatic black hole. The scientists’ research indicates black holes have properties similar to the dynamics of both solids and […]
