NASA looks to grow fresh veggies, 230 miles above the Earth By Jesse Hirsch on September 10, 2013 Photographs by Stephen Allen Last year, an astronaut named Don Pettit began an unusual writing project on NASA’s website. Called “Diary of a Space Zucchini,” the blog took the perspective of an actual zucchini plant on the… Continue reading Space Farming: The Final Frontier
The resulting value for G is 240 parts per million bigger than the official one, set in 2010. James Faller of the University of Colorado at Boulder, who tested G in 2010, is holding out for an error: "Errors are like violets in the springtime: they can spring up in any group's experiment," he says.… Continue reading Strength Of Gravity Shifts, And This Time It’s Serious!

Bad news for Kepler-22b. Once deemed the most habitable world outside our solar system, it no longer looks life-friendly. More strangely, Earth's habitability rating has also taken a hit. Both results are thanks to a redefinition of the habitable zone – the region around a star in which liquid water can theoretically exist. Also known… Continue reading Earth and others lose status as Goldilocks worlds
NASA: Asteroid Apophis Won't Collide With Earth In 2036 http://www.popsci.com/technology/article/2013-01/nasa-asteroid-apophis-wont-collide-earth-2036?src=twitter
The Mars Science Laboratory team has hinted that they might have some big news to share soon. But like good scientists, they are waiting until they verify their results before saying anything definitive. In an interview on NPR today, MSL Principal Investigator John Grotzinger said a recent soil sample test in the SAM instrument Sample… Continue reading Has Curiosity Made an ‘Earth-Shaking’ Discovery?
Astronomy forums are buzzing with speculation about newly-discovered Comet C/2012 S1 (ISON). Currently located beyond the orbit of Jupiter, Comet ISON is heading for a very close encounter with the sun next year. In Nov. 2013, it will pass less than 0.012 AU (1.8 million km) from the solar surface. The fierce heating it experiences… Continue reading BIG SUN-DIVING COMET DISCOVERED
For the first time, astronomers have detected two planets in stable orbits about a binary star system, suggesting that binary stars could have complex planetary systems much like our own. One of the planets in the so-called circumbinary system exists in what astronomers call the habitable zone -- a region where water would remain liquid… Continue reading In a first, astronomers see two planets orbiting binary stars
How did the universe begin? The Big Bang is traditionally envisioned as the moment when an infinitely dense bundle of energy suddenly burst outward, expanding in three spatial directions and gradually cooling down as it did so. Now, a team of physicists says the Big Bang should be modeled as a phase change: the moment… Continue reading Big Bang Was Actually a Phase Change: New Theory
