ASTROBIOLOGIA EM PDF

The NASA Astrobiology Program has announced a bold new structure to mobilize the astrobiology community towards both impacting future NASA space missions and answering the fundamental questions of; How does life begin and evolve? Does life exist elsewhere in the Universe? How do we search for life in the Universe? These RCN s are designed to enable the research community to self-organize, collaborate, communicate, and network across organizational, divisional, and geographical boundaries.

It is common knowledge that the major questions in Science e. Several countries have already responded to this challenge.

One of the fastest growing fields in astrobiology and astrophysics is that of exoplanets and this vast subject will hugely benefit from a European interdisciplinary synergic effort. Chemical sciences will provide rate constants of photochemical reactions and their dependence on physical parameters, e. Earth and planetary sciences will contribute on how planetary interior dynamics critically affect volatile outgassing and cycling, and hence the mass and composition of planetary atmospheres.

Stellar physicists will investigate how key input parameters, like luminosity, activity and effective temperature, modeling the atmospheric evolution of planets affect the planetary energy budget and the atmospheric escape processes. Planetary scientists will study how planet formation influences initial volatile reservoirs and the proto- atmospheres of planets and will determine atmospheric mass and composition.

Finally, engineers will plan future instrumentation for space telescopes to study the atmospheres of rocky exoplanets. These collaborations cannot be organised at a national level and the COST networking structure provides an ideal scheme for securing a leading role for European exoplanet research.

Understanding of the chemical evolution of biomolecules and, subsequently, the first cells, is a vast task exceeding the capabilities of single institutions and national research communities. To understand how the building blocks of life originated from simple molecules, a systemic and transdisciplinary perspective, including astrochemistry, prebiotic chemistry, geology, atmospheric chemistry and engineering is needed.

The explicit adoption of this general perspective through intensive, multi-disciplinary collective work and reciprocal exchange of knowledge is a major goal of the Action. To investigate the formation of biomolecule precursors in space and on planetary surfaces, the Action will create, possibly in association with the Europlanet project, a European Astrobiology Laboratory Network.

This Network will focus primarily on astrochemistry and atmospheric chemistry but will subsequently encompass others fields. It will not only share the competences of leading European Research Laboratories, but will also make maximum use of large instruments for astrochemistry, atmospheric chemistry, extraterrestrial sample analyses and laboratory simulations.

The research community working on prebiotic chemistry and related subjects is large, but the importance of cross- disciplinary and trans-domain activities is still not sufficiently recognized.

The Action will build a platform to initiate collaboration between experts from different research fields in order to advance our understanding of how life can emerge and develop.

In this respect, the international platform provided by this COST trans-domain initiative will help considerably to trigger joint projects that would be otherwise improbable. The duration of the COST Actions provides a sufficiently long timeframe for setting up real collaborations between groups of prebiotic chemists and specialists of other disciplines like geology, planetology, geochemistry and biology.

STSMs are intended especially for young PhD researchers, but they are open to senior researchers as well. View the documents at this link. It should be explicitely noted that Master students are not eligible for STSMs which are for PhD students and more experienced researchers. The Action has specifically excluded the search for intelligent extraterrestrial life in its portfolio.

Individuals are not allowed to use the name of the Action , its logo or any corporate identity of COST TD in any communication without prior approval of the Management Committee. All publications referencing the support of the Action should be sent to the appropriate Working Group chair at the time of submission. Skip to main content. Added value of networking. The added-value for each WG and for the special themes of history of science and philosophy, training and education, dissemination and outreach, which are part of all WGs, are now presented.

Astrobiologia - Uma Ciência Emergente

At present, the study of diverse habitable environments of astrobiological interest has become a major challenge. Due to the obvious technical and economical limitations on in situ exploration, laboratory simulations are one of the most feasible research options to make advances both in several astrobiologically interesting environments and in developing a consistent description of the origin of life. With this objective in mind, we applied vacuum and high pressure technology to the design of versatile simulation chambers devoted to the simulation of the interstellar medium, planetary atmospheres conditions and high-pressure environments. These simulation facilities are especially appropriate for studying the physical, chemical and biological changes induced in a particular sample by in situ irradiation or physical parameters in a controlled environment. Furthermore, the implementation of several spectroscopies, such as infrared, Raman, ultraviolet, etc. Simulation chamber facilities are a promising and potential tool for planetary exploration of habitable environments.

Fungi are not only present on Earth but colonize spacecraft and space stations as well. This review provides an extensive overview of the large and diverse group of fungal species that have been found in space, as well as those corresponding detection methods used and the existing and potential future prevention and control strategies. Many of the identified fungal species in space, such as Aspergillus flavus and Alternaria sp.
