Ever since early humans first looked skyward and imagined the stars as distant campfires, humanity has pondered upon the thought: are we alone in the Universe? The ancient Greeks argued against our home planet being the only cradle for life, the only planet marking the existence of life, but lacked the technology and resources to prove their beliefs. In the late 20th century, the near-simultaneous and truly groundbreaking discoveries of the possible remains of bacterial life in a Martian meteorite, and the first planets orbiting other stars, sparked the question of life beyond the Earth to the forefront of a scientific endeavor, the study of the universe: Astronomy. Today, in the 21st century, the new yet quite intriguing field of Astrobiology harnesses the required technological and scientific capability to seriously address this ancient and fundamental question.
To begin with, Astrobiology is the study of life in the universe. One can look forward to exploring the origin, early evolution, distribution and future of life while studying this field. It ranges from studying the microscopic bacteria in meteors to examining the biological makeup of planets. The search for life beyond the Earth requires an understanding of life, and the nature of the environments that support it, as well as planetary systems and stellar interactions and processes. Therefore, Astrobiology requires knowledge from various specializations such as astrophysics, geology and aeronautical engineering. It may not be everyone’s cup of tea, but it most certainly can be the highlight of your next science discussion!
Is Astrobiology Truly Certifiable?
While Astrobiology is a relatively young field, just spreading its wings to take off for its next venture, it does have a secure and promising future. The elementary reason being that astrobiological research has a significant impact on how agencies such as the National Aeronautics and Space Administration (NASA) and the European Space Agency plan for current and future space missions. For example, many recent missions have focused on exploring worlds in our own solar system for signs of past, present or the precursors of life, including Mars (Phoenix , Pathfinder , Global Surveyor, and others) and Titan (Cassini-Huygens). Additionally, significant advances and investments in telescope technology (Kepler, James Webb Space Telescope) have allowed researchers to begin planning and searching for habitable planets outside our solar system, a quite imperative task science must accomplish, and that would not be possible without advancement in Astrobiology.
Will Astrobiology Graze the Hall of Fame Walls Soon?
The origin and early evolution of life is an inseparable and cardinal part of the discipline of Astrobiology. Astrobiology concerns itself with in depth understanding and analysis of existing scientific data, and although speculation is entertained to give context to this interpretation, Astrobiology is as a whole, the primary hypothesis, that fits firmly, of existing scientific theories. This interdisciplinary field encompasses research on the origin of planetary systems and origins of organic compounds in space, rock-water-carbon interactions, planetary habitability, research on biosignatures for life detection, and studies on the potential for life to adapt to challenges on Earth and in outer space. Can you fathom how this can revolutionize the science we know today?
In conclusion, research into the environmental limits of life and the workings of extreme ecosystems is ongoing, enabling researchers to better predict what planetary environments might be most likely to harbor life. Astrobiology is a growing, blossoming field that must be brought into limelight for the world to admire. It is certainly the beginning of a new era, leading mankind to great discoveries.
