Washington, July 4 : Scientists have confirmed that Mercury’s surface had been formed by volcanic activity early in the planet’s history.

The conclusion is based on an image taken by the Messenger spacecraft as it flew past Mercury in January 2008, which showed a kidney-shaped volcanic vent, surrounded by a halo-like ring and a fainter outer ring.

Earlier, in 1975, the Mariner 10 spacecraft returned intriguing images that showed smooth plains covering large swaths of Mercury’s surface. 

But scientists could not determine whether the plains had been created by volcanic activity or by material ejected from below the surface when objects had collided into it.
