Peering closely at the “heart of Pluto,” in the western half of what mission scientists have informally named Tombaugh Regio (Tombaugh Region), New Horizons’ Ralph instrument revealed evidence of carbon monoxide ice. The contours indicate that the concentration of frozen carbon monoxide increases towards the center of the “bull’s eye.” via NASA http://ift.tt/1fb6Vlr

This image of the sun was taken on July 15, 2015, with the Extreme Ultraviolet Imager onboard NASA’s Solar TErrestrial RElations Observatory Ahead (STEREO-A) spacecraft, which collects images in several wavelengths of light that are invisible to the human eye. This image shows the sun in wavelengths of 171 angstroms, typically colorized in blue. via NASA http://ift.tt/1I5RgRI

On July 7, 2003, NASA launched its second Mars Exploration Rover, Opportunity, aboard a Delta II launch vehicle. Opportunity and its twin rover Spirit landed on Mars in 2004 to begin missions planned to last three months. Both rovers far exceeded those plans. Spirit worked for six years, and Opportunity is still active. via NASA http://ift.tt/1KPBQA4
