NASA released this photo on August 6, 2014, that shows a thin solar prominence above the Sun. The prominence, which is controlled by the sun’s strong magnetic fields beneath it, then sprouted a number of plasma streams that disappeared back into the sun about a day later. NASA said that the photo was taken in extreme ultraviolet light. (NASA/SDO)

In a photo taken August 5, 2014, here’s a look of the pump hall that surrounds the reactor inside the decommissioned, Soviet designed Unit Six of the Greifswald nuclear power station. Located outside the resort town of Lubmin, in was once East Germany, the power plant was just about completed when construction was stopped in 1990 due to the reunification of the then divided nation. The plant was decommissioned because it did not meet the much higher West German safety standards. (Reuters)

Last week we introduced you to the hitch-hiking robot, ‘hitchBOT’ as he prepared to thumb his way across Canada. We check in on hitchBot who is seen here next to Highway 17 north of Sault Ste. Marie, Ontario on August 5, 2014. Latest reports have the robotic hitch-hiker at the halfway point in its cross-country journey. (Reuters)

The European Space Agency’s Rosetta spacecraft met up with its target comet 67P/Churyumov-Gerasimenko this past Wednesday August 6, 2014. This image, taken from a distance of about 120 km, by cameras aboard the spacecraft, shows the comet’s ‘head’ (left), which is casting shadow onto its ‘neck’ and ‘body’ (right). The Rosetta has been flying in space for more than a decade to reach the comet. (AP)
