A massive volcano on Mars, known as Olympus Mons, is being highlighted in new images and research. The volcano is enormous, with its base covering an area comparable to the size of a large region, such as a state or a country, and its peak rising to a great height, nearly three times that of Mount Everest. Details about the volcano, including frozen lava rivers and water frost, are being revealed through various studies and observations, including those from NASA's Mars Odyssey.
