NASA clicks stunning image of International Space Station in front of Sun at 29000 Kmph

The International Space Station (ISS) crossed the Sun at a speed of about 28,968 kilometres per hour. While the ISS was on its way in front of the Sun, NASA captured its picture and it's incredible.

On December 17, when the ISS was just about to make a transit in front of the Sun, Noel Kowsky, a lensman working for NASA, captured the spectacular image of the orbital post.

Kowsky managed to click several images of the event. After combining the 10 pictures, it made a single composite view of the ISS. The picture shows ISS transiting the Sun.

ISS is considered as the largest man-made structure ever to be built in space.
Capturing a photo of such solar transits is no cakewalk as a considerable amount of time to plan and actually pull off is required, 'Tech Times' reported.

The ISS orbits the Earth at an altitude of about 330 to 435 kilometres. So, at times it is very difficult to see it directly without the help of a high-powered telescope.

There is also the challenge of knowing where the space station will be relative to Earth and at what time. Stargazers often use a tracker to find out the location of the ISS.
