Los vecinos más cercanos de la Tierra: el planeta rojo

Mars was once thought to be similar to Earth and possibly host life. However, scientific studies have shown it to be a rocky planet with a thin atmosphere, making it colder than Earth. Spacecraft have explored Mars, revealing its surface contains red iron oxide and dormant volcanoes. Evidence suggests liquid water may have once existed, with frozen water found near the poles. Despite these findings, no life forms have been discovered.
