No, you aren't looking at pictures of blueberries scattered over rocks, but real images of the Martian landscape photographed by the Mars Rover Opportunity. The discovery of these Martian clusters a decade ago provided some of the first evidence of liquid water on the red planet. Continue reading for a video and more information.
The image is part of an exhibition by the Smithsonian's National Air and Space Museum presenting more than 50 of the best photographs from two rovers known as Spirit and Opportunity. The Mars Rover Opportunity found this 'blueberry' cluster at its Eagle Crater landing site and analysed the composition with its spectrometers, and it's been determined that microbes were essential in their formation. This discovery not only reveals that water was present on Mars, but also ancient microbial life.
