ESA Shares Photo Of One of The Biggest Impact Basins On Martian Surface

The European Space Agency (ESA) has shared stunning images of one of the biggest impact basins in the Solar System, located on Mars. Hellas, with a diameter of 1,430 miles (2,300km) and a depth of over 4.3 miles (7km), is believed to have formed between 3.8 billion and 4.1 billion years ago after a large asteroid hit the surface of Mars.
