Using data from NASA’s Kepler spacecraft, astronomers have discovered the first rocky, Earth-sized planet orbiting a distant star. The planet, Kepler-78b, may be 'Earth-sized’ but it is not 'Earth-like.’ It whizzes closely around its host star in just 8.5 hours, and is so hot that it is uninhabitable for life as we know it.
Kepler-78b was first identified by the Kepler space telescope, which has spent four years searching for planets around more than 150,000 stars. Two ...October 30, 2013 / Posted by: Aaron Gronstal

Researchers are collecting together data on photosynthetic pigments from Earth to help imagine the colors of life on other planets.
Plants and other photosynthetic organisms use special molecules for absorbing light. These pigments have a distinctive color, or spectrum ...

Astrobiologists have revealed new information about the structure of RNA molecules found in the ribosome of cells. The study indicates that long-accepted models of ribosomal RNA (rRNA), which are used to study how ribosomes function, require some major updating.
Previous models indicated that rRNA was built out of 6 separate pieces – known as domains. These six domains were organized around a central core, and the structure of this core was a bit of a mystery. This model of rRNA ...October 23, 2013 / Written by: Aaron Gronstal
Please join us in congratulating the NAI’s University of Wisconsin, Madison team in the grand opening of their new Biosignatures exhibit at the University’s Geology Museum this week! The exhibit takes visitors on a journey back in time to examine signatures of life in ancient rocks and fossils, as well as a journey through the senses with the Aromas of Astrobiology installation! A meteorite from Mars is the crown jewel…September 26, 2013 / Posted by: Daniella Scalice
Please note that, in order to include the new director of the NAI in the CAN Cycle 7 process and to make selection with full knowledge of FY14 budgets the Step-2 proposal due date is changed to April 30, 2014. NASA expects that decisions for the Step 1 proposals will be made on or before Dec 18, 2013. In addition, a number of links to NAI websites have been corrected. The full text of the CAN is available electronically at http://nspires.nasaprs.com.
The Step-1 proposal due date changed from November 4, 2013 to November 18, 2013 due to ...September 19, 2013 / Posted by: Julie Fletcher
The NASA Astrobiology Strategy process has reached an important milestone. The concept documents, which were created at the Wallops Island workshop, are now ready for public comment.
The commenting process will be kicked-off with a webinar on the 19th of September at 14:00 EDT. During the event, Frank Rosenzweig, Eric Smith, and Michael New will give an overview of the work done so far, and explain the next steps. More details can be found on the astrobiologyfuture.org website.
The kick-off event will be followed by a series of webinars in which the authors of each paper will discuss ...September 13, 2013 / Posted by: Shige Abe
Potential sites for NASA’s next landing on Mars have been narrowed to four semifinalist located in the Elysium Planitia region. Image credit: NASA/JPL-Caltech
NASA has narrowed down the potential landing sites for the agency’s upcoming InSight mission from twenty-two to just four. The four sites are close together in an area called Elysium Panitia near the martian equator.
InSight (Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport) is a stationary lander that will study the interior of Mars. The lander will deploy a seismometer on the surface and will use a heat probe to penetrate into ...September 9, 2013 / Posted by: Aaron Gronstal

New results from the Sample Analysis at Mars (SAM) investigation on NASA’s Curiosity rover have been reported in two papers in the journal Science. Curiosity has been using SAM to study the atmospheric composition on Mars, and is revealing new clues about how the planet lost much of its original atmosphere.
The findings come from atmospheric samples collected in the first 16 weeks of Curiosity’s mission. The samples were analyzed with ...September 3, 2013 / Posted by: Aaron Gronstal
Comparison of exhumed delta in sedimentary rocks on Mars (left) with a modern delta on Earth (right). On the left, a shaded relief map shows elevated, branching, lobate features in Aeolis Dorsa, Mars, interpreted as resistant channel deposits that make up an ancient delta. These layered, cross-cutting features are typical of channelized sedimentary deposits on Earth and here are indicative of a coastal delta environment.

Scientists supported by NASA have detected water locked in mineral grains on the Moon. The findings hint at unknown water sources deep below the lunar surface. Data for the study came from the NASA-funded Moon Mineralogy Mapper (M3) instrument aboard the Indian Space Research Organization’s Chandrayaan-1 spacecraft.
Chandrayaan-1 used M3 from orbit to remotely detected magmatic water in the central peak of the Moon ...August 28, 2013 / Posted by: Aaron Gronstal
Modeling results show where the injected gas and dust ended up only 34 years after being injected at the disk’s surface. It was injected 9 astronomical units from the central prostar and is now in the disk’s midplane. The outer edge shown is 10 astronomical units from the central prostar. Mixing and transport are still underway and the underlying spiral arms that drive the mixing and transport can be seen. Credit: Image courtesy of Alan Boss

NASA Astrobiology celebrates the 10th anniversary of NASA’s Spitzer Space Telescope and is grateful for all the contributions it has made to astrobiology!
Ten years after a Delta II rocket launched NASA’s Spitzer Space Telescope, lighting up the night sky over Cape Canaveral, Fla., the fourth of the agency’s four Great Observatories continues to illuminate the dark side of the cosmos with its infrared eyes.
The telescope studied comets and asteroids, counted stars, scrutinized planets and galaxies, and discovered ...August 23, 2013 / Posted by: Daniella Scalice
Jan Amend, professor of earth sciences and biological sciences in USC Dornsife, leads an interdisciplinary team of researchers in an investigation into what life teems within Earth’s subsurface biosphere. Their approach could become a template for collecting evidence of life or past life on extraterrestrial planetary bodies such as Mars. Credit: USC/Michelle Salzman
Future life-seeking missions on other worlds may be in for a tough time if all evidence of past or present life is below the surface. In a talk at given for the Space Telescope Science Institute (STScI ) Astrobiology Lecture Series, Jan Amend discussed how his ...

A new study supported in part by NASA has identified a potential origin for ancient water on Mars that was responsible for carving valley networks that branch across the planet’s surface. Scientists identified four water-carved valleys on Mars that were likely caused by runoff from 'orographic’ precipitation. This type of precipitation occurs when moist, prevailing winds blow over mountains and are pushed upward, resulting in snow or rainfall. The research was published in the journal Geophysical Research Letters
