Earlier, it was considered that dark patches on the protoplanet Vesta have occurred due to the geological procedures that would have taken on the planet. However, it is has now been found that the dark patches have occurred due to the collision of asteroids.

The above mentioned revelation has been done through the Dawn Mission carried out by NASA. It was in November only when it was established the dark patches due to carbon -rich asteroids. In order to reach at the above given, the NASA research team started studying the composition of dark spots.

Not only the started studying the composition of dark spots, the research team started creating maps as well as models of the areas. Lead author of the study Vishnu Reddy said that after carrying out a study, they reached at a conclusion that collision of carbon rich asteroids caused the planets to suffer dark patches.

"The evidence suggests that the dark material on Vesta is rich in carbonaceous material and was brought there by collisions with smaller asteroids", said Reddy. He said HED meteorites made them more confident about their hypothesis. Scientists involved in the study find the discovery to be an important one.
