Pluto as seen just before the New Horizons flyby
The day before the spacecraft was set to make its closest approach, Pluto sent us this love letter. The image was taken on July 13 from a distance of 476,000 miles, and it has a resolution of 2.5 miles per pixel. NASA

NASA’s New Horizons spacecraft has just flown by Pluto, making its closest approach at about 7,800 miles from the dwarf planet on schedule at 7:49 a.m. Eastern Time this morning. But about an hour before that, NASA released what it says is a “sneak peak” of the awesome close-ups of Pluto that are yet to come (it takes 4.5 hours for signals to travel between New Horizons and Earth due to the incredible 3 billion-plus mile distance).

Check out this image of Pluto as you’ve never seen it before: reddish, its surface textured with craters and other geologic features, and the dark shapes at its south pole clearly visible. The image was captured at 4 p.m. last night, when New Horizons was still about 476,000 miles away from Pluto’s surface. The resolution is equivalent to 2.5 miles (4 km) per pixel.

According to New Horizons principal investigator Alan Stern, the image could also reveal tectonic activity on the dwarf planet at some point during its past, or even continuing on in the present. But the real revelations are still to come later today and in the coming days, when New Horizons begins returning a wealth of data captured from even closer to Pluto during the flyby.
