NASA Releases Photo And Video Of Christmas-Themed Pluto
NASA’s New Horizons captured some of the most incredible images of Pluto and its moon Charon over the years.

LEISA recorded the movie with a 256 x 256 pixel camera at a speed of two frames per second. It is an extremely clever instrument; it takes 2-D images just like a normal camera, but it takes them through a linearly-varying filter. Each pixel is colored to show the relative wavelength of light that each pixel was allowed to see by LEISA’s linear filter.
It seems like the dwarf planet was the obvious choice for the Christmas makeover since it is known as the coldest planet of the solar system.
The instrument is the infrared imaging spectrometer of New Horizons, named LEISA.
This data has already been used to discover water ice on Pluto, and we might learn even more as NASA continues to study this and other data sets. Since New Horizons’ flyby about six months ago, the space has been releasing stunning pictures of the dwarf planet which show its features in details. NASA has posted both a photo and a video showing how the spacecraft can produce vibrant colors from the seemingly drab-looking dwarf planet.
New Horizons is continuing its journey deep into the solar system now. You can’t say, “Oh, that looks interesting, let’s go take a look”; you have to let the mission make all the observations.
The The Guardian notes that, we planned to pass between Pluto and [its moon] Charon, on the basis that that would sweep up all the pieces; it’s huge, it has extensive gravity, and the debris would fall on it naturally. Between 1930 and 2015, you could draw a whole family of orbits.

One new image and video of Pluto look very pretty, like a Christmas greeting! But it’s not your ordinary movie… it’s actually taking a spectrum of Pluto, mapping out minerals on its surface as the world sweeps by underneath. Three infrared wavelength ranges (2.28-2.23, 1.25-1.30 and 1.64-1.73 microns) were placed into the three color channels (red, green and blue, respectively) to create this false color Christmas portrait.
