A Nasa spaceship has snapped the last possible photos of Pluto’s mysteriously spotty side before it turns away into the darkness for decades.

New Horizons is zooming towards the dwarf planet and will pass by at just 12,500km above the planet’s surface on 14 July, taking lots of close-up photos on the way that scientists hope will help shed some light on the distant planet.

On Thursday, the spacecraft had reached three billion miles away from earth, and beamed back the best images of Pluto to date.

They were “the last, best look that anyone will have of Pluto’s far side for decades to come,” said Alan Stern, principal investigator for New Horizon at the Southwest Research Institute in Boulder, Colorado.

The photos show a string of four dark spots that have captivated the astrology community since they were first spotted. In photos taken further away, the spots looked to be all equally sized.

“It’s weird that they’re spaced so regularly,” said New Horizon scientist Curt Niebur in a statement.

 

The new photos allow a closer look at the four dark spots, which are all roughly the size of the US state of Missouri. It appears that the borders of the darker areas are irregular and sharply defined, according to NASA.

But scientists will have to wait a long time to get an even better look at the spots – as the hemisphere that they are on will soon be out of view.

New Horizons will eventually reach the dark side of the planet but the photos will not be as detailed – as the only light it receives is that reflected from its moon, Charon.

Scientists are looking forward to these photos as some think that snow falls on the side of Pluto away from the sun.  

New Horizons will hurtle past the planet at 14k/s and its long-range camera will, the BBC reported, carpet map two 80km-wide strips of the planet.

NASA scientists back on earth will have to be patient, however, as photos this detailed will take a long time to travel back to earth. It will take about 16 months for a full picture of New Horizon’s findings.
