Mysterious Martian Polygons Reveal Clues of Ancient Water

Scientists have discovered a network of polygon-shaped cracks buried dozens of meters below the surface of Mars in the Utopia Planitia region. These crevasses, spanning 70 meters and bordered by ice and mud, suggest the presence of water and a hospitable climate on Mars billions of years ago. The patterns resemble those found near Earth's poles, indicating that Mars may have once been tilted on its axis, causing temperature fluctuations and the formation of these cracks. The discovery provides valuable insights into Mars' past and its potential for supporting life.
