Unusual Cloud pattern observed by Satellite

Cloud Wake formation observed by MODIS  Look at the 'V' shaped cloud free region.....! The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this natural-color image of the Juan Fernandez Islands on April 29. It is an unusual pattern of wake formation in clouds.....  2 small islands off Chile produced this big effects in the atmosphere. It's all part of Fluid dynamics + atmospheric physics. The islands create obstacles to wind thereby creating a giant V shape of cloud-free air.  Detailed review can be read here:  http://earthobservatory.nasa.gov/IOTD/view.php?id=50718 courtesy:  http://earthobservatory.nasa.gov/

CO2 emissions reach a record high in 2010

CO2 emissions reach a record high in 2010 Energy-related carbon-dioxide (CO2) emissions in 2010 were the highest in history, according to the latest estimates by the International Energy Agency In terms of fuels, 44% of the estimated CO2 emissions in 2010 came from coal, 36% from oil, and 20% from natural gas. more details: http://www.iea.org/index_info.asp?id=1959 and http://blogs.nature.com/news/2011/05/co2_emissions_climb_to_alltime.html

3-D map of universe........

        Astronomers unveiled the most complete 3-D map of the local universe (out to a distance of 380 million light-years) ever created. Taking more than 10 years to complete, the 2MASS Redshift Survey (2MRS) also is notable for extending closer to the galactic plane than previous surveys -- a region that’s generally obscured by dust.
