A messed-up heart shape has been spotted on the Tharsis Bulge on Mars.
The High Resolution Imaging Science Experiment camera aboard NASA's Mars Reconnaissance Orbiter found the heart-shape on the south of the huge shield volcano Ascraeus Mons which measures approximately 200 meters across, Discovery News reported.
Planetary scientist Ramy El-Maarry said that the feature, which is multi-layered and rises above the surrounding landscape, could be an ancient vent structure that has been more resistant to erosion than the surrounding area, which makes it resemble 'inverted' terrains.
