NASA's Science Mission Directorate (SMD) has an extensive Program Officers list of contact information for all of its research programs. Virtually everything SMD does has a contact listed - except Astrobiology. The word is not mentioned at all - even though many of its sub topics are mentioned. NASA issues research solicitations for "Astrobiology" yet they can't be bothered to tell people who to contact for the programs managed under "Astrobiology" at NASA?

Can multicellular life be distinguished from single cellular life on an exoplanet? We hypothesize that abundant upright photosynthetic multicellular life (trees) will cast shadows at high sun angles that will distinguish them from single cellular life and test this using Earth as an exoplanet.

The National Academies of Science, Engineering, and Medicine along with the NASA Science Mission Directorate have reached consensus on the Statement of Task for the next decadal survey in planetary science and astrobiology. The Statement of Task will serve as a guiding document for the Planetary Science and Astrobiology Decadal Survey 2023-2032.

When the Earth was born, it was a mess. Meteors and lightning storms likely bombarded the planet's surface where nothing except lifeless chemicals could survive.

The Network for Life Detection (NfoLD) is a NASA Research Coordination Network focused on advancing life detection research by building a strong, diverse, and interactive community of scientists and technologists.

AbGradCon 2019 Talks Are Now Online

The 15th Astrobiology Graduate Conference (AbGradCon) was held from July 22-26, 2019 at the University of Utah in Salt Lake City, Utah, with 75 participants presenting 31 talks and 44 posters.

Astrobiology Is At A Pivot Point

A Twitter sequence about the present and future of Astrobiology.

Sometimes Twitter is a better way to encapsulate a thought than a simple narrative.

The first minerals to form in the universe were nanocrystalline diamonds, which condensed from gases ejected when the first generation of stars exploded.

The Planetary Science Division intends to solicit Interdisciplinary Consortia for Astrobiology Research (ICAR) to support the goal of the NASA's Astrobiology program in the study of the origins, evolution, and distribution of life in the universe.

Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe. It is an inherently interdisciplinary field that encompasses astronomy, biology, geology, heliophysics, and planetary science, including complementary laboratory activities and field studies conducted in a wide range of terrestrial environments. Combining inherent scientific interest and public appeal, the search for life in the solar system and beyond provides a scientific rationale for many current and future activities carried out by the National Aeronautics and Science Administration (NASA) and other national and international agencies and organizations.

Call for Authors: Astrobiology Primer 3.0

Are you an early-career astrobiologist? Would you be interested to contribute to an Astrobiology primer? The first primerwas published in 2006 and second was published in 2016. Now, we are working on the third edition which be hosted as a living document in a NASA-sponsored website.

When we think of life on Earth, we might think of individual examples ranging from animals to bacteria. When astrobiologists study life, however, they have to consider not only individual organisms, but also ecosystems, and the biosphere as a whole.

The existence of intelligent, interstellar traveling and colonising life is a key assumption behind the Fermi Paradox.

Could there be another planet out there with a society at the same stage of technological advancement as ours?

Since its inception six decades ago, astrobiology has diversified immensely to encompass several scientific questions including the origin and evolution of Terran life, the organic chemical composition of extraterrestrial objects, and the concept of habitability, among others.

To advance the search for life in the universe, NASA should support research on a broader range of biosignatures and environments, and incorporate the field of astrobiology into all stages of future exploratory missions, says a new congressionally mandated report from the National Academies of Sciences, Engineering, and Medicine.

Astrobiology, the study of the origin, evolution, distribution, and future of life in the universe, is a rapidly changing field, especially in the years since the publication of NASA's Astrobiology Strategy 2015. Recent scientific advances in the field now provide many opportunities to strengthen the role of astrobiology in NASA missions and to increase collaboration with other scientific fields and organizations. The report finds that these changes necessitate an updated science strategy for astrobiology.

Recently, many Earth-sized planets have been discovered around stars other than the Sun that might possess appropriate conditions for life.

Are we alone in the universe? Astrobiology, the study of the origins of life in the universe and the search for life on other worlds, is a highly interdisciplinary and rapidly changing field at the intersection of biology, chemistry, geology, planetary science, and physics.

Astrobiology, the study of the origin, evolution and future of life on Earth and beyond, is a multidisciplinary field that has expanded rapidly over the last two decades.

The John W. Kluge Center has opened the competition for the 2019 Baruch S. Blumberg NASA/Library of Congress Chair in Astrobiology
