The HOUSE BAND OF THE UNIVERSE is bringing LIFE OUT THERE on a cosmic tour around the Milky way galaxy, and is stopping for ONLY FOUR NIGHTS ON EARTH!!!
2 nights only in Washington DC (7/25-26) and 2 in Chicago (7/29-30), to wow audiences with mind-blowing, real, never-before-seen, cosmic-astronomical visuals and the funky, funky sounds of the House Band of the Universe.
What is life, really? How did it begin on Earth and where else might we find it in our solar system and beyond? David Grinspoon, an astrobiologist at the Library of Congress, and Ka Chun Yu ...July 18, 2014 / Posted by: Daniella Scalice
Motivated by the rapidly increasing number of known Earth-sized planets, the increasing range of extreme conditions in which life on Earth can persist, and the progress toward a technology that will ultimately enable the search for life on exoplanets, the Vatican Observatory and the Steward Observatory conducted a major conference entitled The Search for Life Beyond the Solar System: Exoplanets, Biosignatures & Instruments in March, 2014.
All the sessions were recorded and are archived here.
The conference brought together the interdisciplinary community required to address this multi-faceted challenge: experts on exoplanet observations, early and extreme life on Earth, atmospheric biosignatures, and ...July 18, 2014 / Posted by: Daniella Scalice
Data management and sharing are growing concerns for scientists and funding organizations throughout the world. Funding organizations are implementing requirements for data management plans, while scientists are establishing new infrastructures for data sharing. One of the difficulties is sharing data among a diverse set of research disciplines. Astrobiology is a unique community of researchers, containing over 110 different disciplines.
In this new study, the results of a survey of data management practices among scientists involved in the astrobiology community and the NASA Astrobiology Institute (NAI) in particular are presented. The results of the survey show that the astrobiology community shares ...July 14, 2014 / Written by: Daniella Scalice

Astrobiologists from the United States and Germany have recorded the highest level of UV radiation from the Sun yet known at the Earth’s surface.
You might expect the highest radiation levels of this type on Earth to be somewhere in Antarctica – underneath the hole in Earth’s ozone layer. This layer of Earth’s stratosphere contains higher concentrations of ozone gas (O3) than the rest of the atmosphere, and ...July 11, 2014 / Written by: Aaron Gronstal
How do we define “life?” This fundamental question has remained largely philosophical, because it has been asked for so long, by so many, and with so few concrete conclusions.
In this seminar, produced by the NASA Astrobiology Institute, Dr. Steven Benner takes a different tack. He shows how laboratory studies can create a second example of life, helping us develop a firmer scientific understanding of what life is. The challenge of “synthetic biology” is on!
Dr. Benner discusses how we are hitchhiking on rockets, rovers, and telescopes to find life elsewhere in the Solar System, and describes how his research ...July 9, 2014 / Posted by: Daniella Scalice
In this fascinating interview, the Huffington Post’s Suzan Mazur talks with NAI Principal Investigator Nigel Goldenfeld, of the University of Illinois, Urbana-Champaign. They discuss the emergence of a new theory of life, the nature of the evolutionary process, the origin of life, and more.
“Our collaborative position was that the Modern Synthesis is simply not enough,” said Goldenfeld, “population genetics is not a full account of the evolution process because it manifestly does not describe evolution before genes, it does not describe evolution before there were species and the lineages. The Modern Synthesis wasn’t designed to do so ...

What astronomers thought were a pair of potentially life-friendly alien worlds are illusions, apparitions conjured up by a star’s intense magnetic activity, a new NAI-funded study suggests.
These new findings could one day not only help astronomers dispel more such illusory exoplanets, but discover worlds that would otherwise remain hidden, scientists added. A new video about the possible cosmic illusions also details the finding.
Astronomers have confirmed the existence of more than 1,700 planets beyond the solar ...
In a new study, scientists compared three-dimensional structures of ribosomes from a variety of species, showing where new structures were added to the ribosomal surface without altering the pre-existing ribosomal core, which originated over 3 billion years ago before the last universal common ancestor (LUCA) of life.

The evolution of the ribosome, a large molecular structure found in the cells of all species, has been revealed in unprecedented detail in a new study published this week in PNAS.
In a new study co-funded by the NASA Astrobiology Institute, scientists compared three-dimensional structures of ...July 2, 2014 / Posted by: Daniella Scalice

The Coursera Massively Open On-Line Course (MOOC), Emergence of Life, is built upon the pioneering work of Carl Woese, on which the modern synthesis of the Tree of Life has been established.
No prior knowledge is required, just a willingness to learn and a desire to delve into Earth’s 4-billion-year history of Life. The course will traverse from the ancient primordial soup into the expansive and diverse Tree of Life, and how these understandings might point us towards the existence of Life elsewhere in the universe.
The University of Illinois Urbana-Champaign College of Liberal Arts and Sciences, the NASA ...June 30, 2014 / Posted by: Daniella Scalice

Roy Price first heard about the hydrothermal vents in New Caledonia’s Bay of Prony a decade ago. Being a scuba diver and a geologist, he was fascinated by the pictures of a 38-meter-high calcite “chimney” that had precipitated out of the highly-alkaline vent fluid.
His attraction to this South Pacific site intensified over the years, as it was later revealed that the geochemistry of the hydrothermal fluids discharging in the Bay of Prony resemble that of ...
Sugars of extraterrestrial origin have been observed in the interstellar medium (ISM), in at least one comet spectrum, and in several meteorites that have been recovered from the surface of the Earth. The origins of the sugars within the meteorites have been debated.
To explore the possibility that sugars could be generated during shock events, a new study funded by the NASA Astrobiology Program is the first set of laboratory impact experiments wherein glycolaldehyde, found in the ISM, as well as glycolaldehyde mixed with montmorillonite clay, have been subjected to reverberated shocks.
New biologically-relevant molecules, including threose, erythrose and ethylene ...June 18, 2014 / Posted by: Daniella Scalice

Astrobiologists have solved a 55-year-old Moon mystery known as the Lunar Farside Highlands Problem.
When looking at the Moon from Earth, one of the first things you notice are the large, dark areas of basalt seas known as maria. These dark spots are what give the Moon it’s familiar 'face.’ For centuries this was the only view of the Moon that humankind knew because the nearside always faces ...June 13, 2014 / Written by: Aaron Gronstal
