How might life arise other places in the universe and what might it be like? Astrobiology's goal of promoting interdisciplinary research is an attempt to reverse a trend that began two centuries ago with the formation of the first specialized scientific disciplines. While the authors of both the Viking results and the Mars meteorite results stand by their work, the scientific consensus has largely rejected them — concluding that the findings could be explained without the presence of biology. On-going research suggests that the water is salty, a brine with apparent parallels to our oceans. Astrobiology, in contrast, is the study of questions about the relationship between life, and the chemistry and physics of the universe. The famous ALH84001 meteorite, uncovered in the Allan Hills region of Antarctica in 1984, was presented as containing clear signs that microbial life once existed on Mars. Since then thousands more have been identified, especially by NASA’s Kepler Space Telescope, but also through ground-based observations. Nonetheless, the possibility of actually finding extraterrestrial life reached a fever pitch of excitement during the Viking landing in 1976. Astrobiology, so far, focuses mainly on life on Earth, since it is the only example of life we have. Astrobiology is the field of science devoted to searching for life elsewhere in the Universe. Numerous efforts to expand the capacities of spectrometers so they can better characterize organic compounds and possible biological activity on other planets. Its goal is to understand these relationships in the broad context of life in the universe. Amino acids, for instance, were found in samples of the comet Wild 2 after NASA’s Stardust spacecraft passed through the comet’s dusty coma in 2004, and nucleotides have been discovered by NASA scientists in meteorites. Although no compelling evidence of extraterrestrial life has yet been found, the possibility that The authors explain how research on the origin of life became wedded to the search for life on other planets and for extraterrestrial intelligence. The establishment of cosmology as a science provides a parallel to the building-up of the scientific status of astrobiology. From the publisher: “The Living Universe is a comprehensive, historically nuanced study of the formation of the new scientific discipline of exobiology and its transformation into astrobiology. Other work goes into technology development for use on other planets and moons, while other research explores the origins and early development of life on our planet. The experience was sufficiently sobering that the study of Mars took an abrupt backseat, and it would be decades before interest recovered. Because oxygen and ozone quickly bond with other elements, the presence of large reservoirs of elemental oxygen, for instance, would tell scientists that it is constantly being produced. Astrobiology encompasses the search for habitable environments in our Solar System and on planets around other stars; the search for evidence of prebiotic chemistry … Scientists have determined that some of the planets are rocky and “Earth-like,” and orbiting their sun well within a “habitable zone” – at a distance where water can remain liquid on the surface of the planet for at least some of the time. In 1997, NASA established an Astrobiology program (the NASA Astrobiology Institute - NAI) as a result of a series of new results from solar system exploration and astronomical research in the mid-1990s together with advances in the biological sciences. Some of the work involves studying environments on Earth to better understand potentially similar ones beyond Earth (so-called “analogue environments”). It is succinctly encapsulated by the so-called Drake Equation. That effort required substantial research into and inevitable debate about the nature of the “life” that the Viking landers would be looking for. Astrobiology is a scientific discipline that studies the phenomenon of life and its relation to the physical universe. Image credit: NASA Ames/JPL-Caltech/Tim Pyle. The findings of astrobiology have already influenced how NASA and ESA (European Space Agency) make plans for their explorations of space and shaped the way they handle their missions. The 2000s saw a renewed interest in exploring Mars with NASA orbiters, landers, and rovers. As with the Viking results, however, many in the Mars and astrobiology communities were not convinced. He also writes the Many Worlds blog. The efforts of their missions went in the direction of examining the solar system that we live in, hoping that they will find evidence for any past o… As it discussed the challenges of integrating astronomical research into the general enterprise of astrobiology, the committee realized that the issue of integration was broader and generic to this intrinsically interdisciplinary subject—that is, astrophysics is but one of many disciplines that need to be brought to bear on astrobiology. Among many other themes, the authors analyze how research on the origin of life became wedded to the search for life on other planets and for extraterrestrial intelligence. We call it a discipline and not a science because some authors have cast doubts over its epistemological status by calling it 'a science without an object of study'.

The NASA Astrobiology Institute was founded two years after the Mars meteorite paper was released, with Nobel laureate Baruch Blumberg as its director, and the organization has been funding wide-ranging research ever since. Nonetheless, the Mars meteorite and the excitement surrounding it gave a jumpstart to NASA’s renewed search for life beyond Earth. That’s because the past twenty years have witnessed a revolution in our understanding of exoplanets – bodies that orbit distant suns. Marc Kaufman is an experienced journalist, having spent three decades at the Washington Post and the Philadelphia Inquirer, and is the author of two books on searching for life and planetary habitability. As technologies and scientific understandings have progressed, astrobiology has entered ever more fields. Moving beyond the astronomical detections of a cosmic menagerie of exoplanets, efforts are now underway to analyze the atmospheres, and ultimately the surfaces, of those bodies. Intensive research into stromatolites – the ancient reef-like structures that have flourished for 3.5 billion years on Earth and may present a model for lifeforms on other planets. While the 1960s were defined within NASA primarily by the efforts to land humans on the Moon, all during that period the agency was also supporting a robust effort to prepare for a mission to Mars. The Living Universe is a comprehensive, historically nuanced study of the formation of the new scientific discipline of exobiology and its transformation into astrobiology. Astrobiology encompasses a wide range of scientific disciplines and investigations, ranging from laboratory experiments to telescopic observations to in situ studies on alien worlds. How can we search for life on other planets?In the late 1960s and 1970s a field emerged called exobiology, which was intended to be the study of extraterrestrial life. He won the Nobel Prize (at age 33, for discoveries about the genetics of bacteria) the same year NASA was founded. What Are The Requirements For Life To Arise And Survive? Fortunately, a great deal had been learned in the intervening years. The first major “extremophile” discovery was made in the blackness of the deep ocean off the Galapagos Islands, alongside the hydrothermal vents that dot the seafloor. The MER rovers, Opportunity and Spirit, detected carbonates and other minerals important to understanding the potential for biology in the martian past. Astrobiology considers the question of whether extraterrestrial life exists, and if it does, how humans can detect it.
