Study: Global warming sparked by ancient farming methods

Ancient man may have started global warming through massive deforestation and burning that could have permanently altered the Earth’s climate, according to a new study by researchers at the University of Virginia and the University of Maryland-Baltimore County. The study, published in the scientific journal Quaternary Science Reviews and reported on the University of Virginia’s Web site, says over thousands of years, farmers burned down so many forests on such a large scale that huge amounts of carbon dioxide were pumped into the atmosphere. That possibly caused the Earth to warm up and forever changed the climate

Kepler telescope makes quick discovery

NASA’s Kepler space telescope has already made a discovery, and its science operations aren’t even officially under way yet. NASA scientists who put the telescope through a 10-day test after its March 6 launch said this week that Kepler is working well. Its ability to detect minute changes in light has enabled scientists to determine that a planet orbiting a distant star has an atmosphere, shows only one side to its sun and is so hot it glows

Mystery impact leaves earth-size mark on Jupiter

Jupiter is sporting a new scar after a mystery object hit the gaseous planet this week, NASA scientists say. An amateur astronomer in Australia noticed the new mark on the planet Sunday and tipped off scientists at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, who then confirmed it was the result of a new impact, NASA said. It’s not clear what the object was that crashed into Jupiter’s poisonous atmosphere.
