In our solar system's eight planets, Earth stands alone as the miraculous haven for life and civilized society.
While celestial bodies like Venus and Mercury present extreme conditions, Earth's distinct seasons and moderate climate make it unique.
Scientists have identified Mars as the most Earth-like planet among its neighbors after extensive comparisons. Since 1877, astronomers have observed Mars, initially mistaking surface features for evidence of Martian civilization. Subsequent exploration, which began in the 1960s, aimed to unravel the mysteries of Mars, including the search for signs of life.
Recent breakthroughs emerged when scientists, using ground-penetrating radar on an orbiter, unveiled a 20-kilometer-long saltwater lake beneath a massive glacier near Mars’ south pole. This discovery, detailed in the journal Science, opens new avenues for potential water supply and life detection on Mars.
NASA scientist Green emphasizes the lake’s significance, noting that it differs from previously identified surface water. Despite its modest dimensions—less than 20 kilometers in diameter and approximately 1 meter thick—the underground lake suggests that Mars may have once been a blue planet covered by oceans.
With temperatures plunging below minus 70 degrees Celsius, the lake becomes a crucial focal point for human exploration, as it may harbor evidence of past or even current Martian life. Oceanographer Ethan White argues that if microbes can endure Earth’s polar glaciers, Mars, with its extreme conditions, might similarly support life.

Analyzing the lake’s composition through a lander holds promise for future revelations, but this endeavor presents formidable challenges. Drilling 1.6 kilometers into the Martian surface requires sophisticated equipment, and ensuring that samples remain uncontaminated by Earth microbes is a complex task.
While the realization of such a mission remains distant due to technological and logistical hurdles, the discovery sparks hope for unraveling Mars’ enigmatic past and its potential for life.
The solitude of life in our solar system remains an Earthly anomaly, with only our planet fostering civilization. The harsh conditions on neighboring celestial bodies, such as Venus with its scorching temperatures and dense atmosphere, or Mercury, which endures the intense heat of the sun’s proximity, render them inhospitable.
