NASA scientists have determined that a primitive ocean on Mars held more water than Earth's Arctic Ocean and that the Red Planet has lost 87 percent of that water to space. Image Credit: NASA/GSFC
A primitive ocean on Mars held more water than Earth’s Arctic Ocean, according to NASA scientists who, using ground-based observatories, measured water signatures in the Red Planet’s atmosphere. Scientists have been searching for answers to why this vast water supply left the surface. Details of the observations and computations appear in Thursday’s edition of Science magazine.

NASA scientists studying the origin of life have reproduced uracil, cytosine, and thymine, three key components of our hereditary material, in the laboratory. They discovered that an ice sample containing pyrimidine exposed to ultraviolet radiation under space-like conditions produces these essential ingredients of life.
The research was funded by the NASA Astrobiology Institute (NAI) and the NASA Origins of Solar Systems Program.

On the radio program Big Picture Science, David Grinspoon recently joined a discussion about the impacts of humankind on planet Earth. Right now, the Earth is in a geological epoch known as the Holocene. However, some scientists believe we have moved into a new epoch dubbed the 'Anthropocene,’ or the age of man.

The 2015 International Summer School in Astrobiology will be held at the summer campus of the Universidad Internacional Menéndez Pelayo (UIMP), Palacio de la Magdalena, Santander, Spain on June 29 – July 3, 2015.
This year’s theme will be The Origin of Life: From Monomers to Cells. The school will provide an interdisciplinary examination of the chemical, physical and geological processes that are required to develop cellular life, and discuss the different environmental settings that would support these processes. Topics covered will include an introductory overview of origin of life research and future directions, planetary environments for life’s origin ...March 9, 2015 / Written by: Julie Fletcher

Organizers of last year’s successful online Spanish course, “Planetología y Astrobiología,” have awarded the first Prize of Planetology and Astrobiology to recognize the contributions of two outstanding students.
First Prize was awarded to Ruben Campanero, a Geologist specializing in chondritic meteorites. Honorable Mention went to Verónica Casanova, a student of Physics at the National Distance Education University.

A new study supported by the NASA Astrobiology Institute (NAI) indicates that some terrestrial planets in the habitable zones of low mass stars could be the evaporated cores of small Neptune-like planets.
University of Washington (UW) graduate student Rodrigo Luger, professors Rory Barnes and Victoria Meadows, and collaborators published results from an interdisciplinary model that show photoevaporation can remove hydrogen and helium from small, gaseous exoplanets, transforming them into ...March 4, 2015 / Posted by: Aaron Gronstal

A new study of emissions from Martian volcanoes suggests there is no activity going on right now, but researchers aren’t ruling out recent eruptions.
Previously, scientists have used ground-based telescopes to perform short-term searches for sulfuric acid on Mars — a key indicator of volcanic activity. Now, a new instrument on Europe’s next Mars spacecraft could be used for long-term, up-close searches.

Scientists have discovered 1.8 billion-year-old fossil microorganisms in fossilized deep-sea mud from Western Australia. It appears that the sulfur-cycling microbial community is almost identical to microbial fossils from 2.3 billion-years-ago, and to modern communities found off the coast of South America.
The stability of these communities could be evidence of a long-term lack of evolution, which reflects the lack of change in their environment. This would be an example of a theory known as evolution ...February 26, 2015 / Written by: Aaron Gronstal

Lisa Kaltenegger, Cornell University
A telescope will soon allow astronomers to probe the atmosphere of Earthlike exoplanets for signs of life. To prepare, Lisa Kaltenegger and her team at Cornell’s Institute for Pale Blue Dots are modeling the atmospheric fingerprints for hundreds of potential alien worlds. They are building a database of atmospheric fingerprints that will then be used as “ID cards” to guide the study of exoplanet atmospheres with the James Webb Space Telescope and other future large telescopes.
Kaltenegger described her approach in a talk for the NASA Astrobiology Institute’s Director Seminar Series last December.

Bill Bottke of Southwest Research Institute will be presenting the next NAI Director’s Seminar on February 23, 2015, at 1pm Pacific Standard Time. A link to the web broadcast will be available here at 12:45pm PST on Feb 23.
Bottke’s talk, “Early Solar System Bombardment and Earth’s Habitability,” will discuss insights about the bombardment history of the early Earth based on a new bombardment model for the inner Solar System that stretches from Mercury to the asteroid belt.
