See Pluto's frozen 'heart' in amazing detail
The mysterious face of Pluto is beginning to yield some of its secrets in this stunning false-color image from NASA's New Horizons spacecraft, which scientists can use to detect subtle differences in the dwarf planet's surface, including its icy "heart."
罢丑别听, released on Thursday (July 23), clearly shows the now familiar heart-shaped region nicknamed Tombaugh Regio. The photo is actually a combination of observations from the main camera on New Horizons (called LORRI) and the probe's visible/infrared imager (known as Ralph) which provided data for the colors in the view. The enhanced colors allow scientists to identify differences in the composition and texture of Pluto's surface, according to a NASA image description.听
"The 'heart of the heart,' Sputnik Planum, is suggestive of a source region of ices,'" NASA officials wrote in the image description. Sputnik Planum is the vast plains region inside Pluto's heart-shaped feature. "The two bluish-white 'lobes' that extend to the southwest and northeast of the 'heart' may represent exotic ices being transported away from Sputnik Planum." []

Four images from the probe's LORRI camera (short for Longe Range Reconnaissance Imager) were combined with the color data from the Ralph instrument to create this view.听

NASA will unveil more new photos of Pluto from New Horizons later today at 2 p.m. EDT (1800 GMT) during a press conference at its headquarters in Washington, D.C. You can听, courtesy of NASA TV.听
