Looking for Alien Lasers, One Photon at a Time
Topic: Alien Life
Prior attempts to look for alien laser signals concentrated on isolated and intense bursts of light. Now scientists are focusing on repetitive but much fainter laser signals received over a longer amount of time.

Exploring the World of Life Underground
Topic: Extreme Life
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 STScI Astrobiology Lecture Series, Jan Amend discussed how his team is taking the next step in studying microbes that have conquered the subsurface of the Earth, and how techniques will need to be perfected before they can be successfully used on another planet.

'Water-Trapped' Worlds
Topic: Cosmic Evolution
A new study takes a deeper look into the fate of water on Earth-like planets that orbit red dwarf stars. Many of these exoplanets quickly become "tidally locked," with one side always facing their reddish star while the other side freezes in permanent night.

The Color of the Ocean: the SABIA-Mar Mission
Topic: Climate
By monitoring the color changes in the ocean, such as those caused by photosynthetic pigments in phytoplankton, scientists learn more about the overall health and functioning of our planet. Such studies also could help future missions better observe and understand alien oceans.

Technology Could Curtail Astronaut Conflict
Topic: Moon to Mars
NASA plans to send the first humans to Mars sometime in the next quarter-century. Such a mission will push the boundaries of teamwork for the handful of astronauts selected, so scientists are developing devices aimed at monitoring astronauts to learn how cooperation fluctuates over the course of a mission.

Autonomous Rover Drills Underground in the Atacama
Topic: Robotics & A.I.
A rover named Zoë recently traveled to the dry, harsh terrain of Chile's Atacama Desert. Equipped with a drill, cameras, spectrometers and other sensors, Zoë spent two weeks analyzing the soil from above and below the surface, providing valuable data for future missions to Mars.

Travelogue from Young Researchers in the Field
Topic: Extreme Life
The Lewis and Clark Fund for Exploration and Field Research in Astrobiology fosters the "pioneering" efforts of graduate students and post-doctorate researchers as they step out of the lab and into the field.

Antifreeze on Titan Could Affect Its Chances for Life
Topic: Titan
Scientists have found that a common antifreeze compound that might exist on Saturn's moon Titan can get trapped within ice-like cages. This discovery could influence our ideas about the evolution and development of life on Titan and other icy celestial bodies.

The Next Step for Astrobiology’s Roadmap
Topic: Missions
The Astrobiology Program has completed the first phase of development for the next Astrobiology Roadmap. Over 500 participants joined in webinars and discussions that will shape the future of astrobiology research at NASA. Today, experts will gather for a workshop to discuss the results of the online events.

Precious Opals Shine a Light on Mars
Topic: Mars
Research that sheds light on how Australian opals formed indicates the red dirt in the land Down Under might be similar to the red surface of Mars.
