  • The yellowish or orange dunes in Mars represent a warmer climate.

A recent picture of the planet Mars has been shared by the National Aeronautics and Space Administration (NASA). According to the picture, it portrays that the surface of the Red Planet looks somewhat like electric blue in color.

The image was taken by the Odyssey orbiter using Thermal Emission Imaging System (THEMIS). This helped the agency to get a clear and high-definition picture of the dunes. The image, shared by the space agency with the title ‘Blue Dunes on the Red Planet’, combines the shots taken between December 2002 and November 2004.

To mark the 20th anniversary of Odyssey, the images clicked on the Red Planet at 80.3 degrees north latitude, 172.1 degrees east longitude, was released. The Odyssey turned out to be the longest-working Mars spacecraft in history.

Coming to the picture, two types of dunes can be witnessed i.e., yellowish or orange dunes that signify warmer climates, and bluish or pale, lagoon-like dunes that represent colder climates. An official of NASA explained that the areas with cooler temperatures are recorded in bluer tints, while warmer features are depicted in yellows and oranges. Thus, the dark, sun-warmed dunes glow with a golden color. “The image shared by us covers an area 19 miles (30 kilometers) wide,” the official added.
