Latest Pluto closeups zoom in on mysterious features

NASA's latest images of Pluto include a stunning colour closeup of its mountains and plains and an image featuring intriguing patterns of pits that scientists have trouble explaining.

Images taken as spacecraft made its closest approach to the dwarf planet in July

NASA's latest images of Pluto contain intriguing patterns of pits that scientists have trouble explaining.

The pits, which are several metres deep and hundreds of metres across, appear across a section of Pluto's pale, heart-shaped feature, nicknamed Tombaugh Regio in images captured by the New Horizons spacecraft.

The spacecraft has been sending back images captured during its historic flyby of Pluto and its moons on July 14.

An intricate pattern of pits appears across a section of Pluto’s prominent heart-shaped region, informally named Tombaugh Regio. Each one is hundreds of metres across and tens of metres deep, and they're thought to have formed from a combination of ice fracturing and evaporation. This image is 80 by 80 kilometres across.

New Horizons mission scientists think the pits may have formed through a combination of ice fracturing and evaporation.

Along with the closeup of the pits, released late last week, NASA also released a colour closeup featuring badlands, mountains and plains at the edge of Tombaugh Regio.
