A team using the Sample Analysis at Mars (SAM) instrument suite aboard NASA’s Curiosity rover has made the first detection of nitrogen on the surface of Mars from release during heating of Martian sediments. The nitrogen was detected in the form of nitric oxide, and could be released from the breakdown of nitrates during heating. Nitrates are a class of molecules that contain nitrogen in a form that can be used by living organisms. The discovery adds to the evidence that ancient ...March 26, 2015 / Posted by: Aaron Gronstal

Using NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA), an international scientific team discovered that supernovae are capable of producing a substantial amount of the material from which planets like Earth can form.
These findings are published in the March 19 online issue of Science magazine.

A decade after landing on Titan, data from the Huygens probe is helping scientists understand how the atmosphere of Saturn’s mysterious moon was formed.
The study, “Noble gases, nitrogen, and methane from the deep interior to the atmosphere of Titan,” was published in the journal Icarus by lead author Christopher Glein. Glein was member of the former NAI Team at Arizona State University and is now a postdoctoral researcher at the University of Toronto in Canada.

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

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.
