“Although the question of why our universe has exactly three (large) spatial dimensions is one of the most profound puzzles in cosmology … it is actually only occasionally addressed.” The most distinctive characteristic of a radical new theory is that... Continue reading

“We found that Mars’ magnetic tail, or magnetotail, is unique in the solar system,” said Gina DiBraccio of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It’s not like the magnetotail found at Venus, a planet with no magnetic field... Continue reading

"The search for planets is the search for life," said Natalie Batalha, a Kepler mission scientist from NASA's Ames Research Center. "These results will form the basis for future searches for life." "Forty years ago, people got laughed at when... Continue reading

"We're not saying nothing happened," said co-author Dr William Foster, a palaeontologist from the Jackson School of Geosciences at the University of Texas at Austin. "Rather, global oceans in the extinction's aftermath were a bit like a ship manned by... Continue reading

"As human-caused global warming drives sea levels higher and higher, we are literally reshaping the surface of our planet," said Josh Willis, NASA project scientist at NASA's Jet Propulsion Laboratory in Pasadena, California. "These missions tell us how much and... Continue reading

Previous NASA models simulated atmospheric conditions along one dimension, the vertical. Like some other recent habitability studies of alien planets, the new research used a model that calculates conditions in all three dimensions, allowing the team to simulate the circulation... Continue reading

Since NASA's Dawn mission fits went into orbit around Ceres, evidence has been found for organic material on the dwarf planet, the largest body in the main asteroid belt between Mars and Jupiter. Scientists using the spacecraft's visible and infrared... Continue reading

“My feeling is that if a human being can coax life to build bonds between silicon and carbon, nature can do it too,” said Frances Arnold a chemical engineer at the California Institute of Technology, about implications that new findings... Continue reading

"All of our observations find a complete symmetry between matter and antimatter, which is why the universe should not actually exist," explained Christian Smorra, with the BASE collaboration at the CERN research center. "An asymmetry must exist here somewhere but... Continue reading

Millions of years ago, a mountain range that would have dwarfed the Andes mountains (above) in South America, stretched over what is currently the southern-most tip of Africa. Remnants of these mountains - called the Gondwanides, after the massive supercontinent,... Continue reading

"Every single one of those stars could have a New York City, a Paris, a London, and we would have no idea,” said Nate Tellis of the University of California, Berkeley about the 5,600 stars analyzed in a study released... Continue reading

"This is a huge discovery," said Ryan Foley at UC Santa Cruz. "We're finally connecting these two different ways of looking at the universe, observing the same thing in light and gravitational waves, and for that alone this is a... Continue reading

"We should not expect to see any other forms of life that are genetically, functionally and intellectually similar to us." says Charles Lineweaver, a noted astrobiologist at the Australian National University. "I strongly suspect that our closest relatives in the... Continue reading
