Astrobiology is the scientific study of the origins, evolution, distribution, and future of life in the universe. It integrates disciplines like astronomy, biology, geology, and chemistry to investigate the potential for life beyond Earth.
Astrobiologists search in various locations, including Mars, Jupiter's moon Europa, Saturn's moon Enceladus, and exoplanets within habitable zones, looking for signs of water, organic molecules, and energy sources.
Biosignatures are any substance, object, or pattern whose origin necessitates a biological agent. Examples include specific organic molecules, isotopic ratios, cellular structures, or atmospheric gases indicative of life processes.
As of now, definitive, undisputed evidence of extraterrestrial life has not been discovered. However, the search continues, with ongoing missions and research identifying potentially habitable environments and promising biosignatures.
