Extrasolar Planets
Ground-based optical transmission spectroscopy of the small, rocky exoplanet GJ 1132b 
Terrestrial Solar System planets either have high mean molecular weight atmospheres, as with Venus, Mars, and Earth, or no atmosphere at all, as with Mercury.
Origin & Evolution of Life
Organic Chemistry In A CO2 Rich Early Earth Atmosphere
The emergence of life on the Earth has required a prior organic chemistry leading to the formation of prebiotic molecules. The origin and the evolution of the organic matter on the early Earth is not yet firmly understood.
Mars
Using Dorset UK as Model to Help Find Traces of Life on Mars
By studying a stream on the UK coast, experts have calculated how much organic matter we might find on Mars, and where to look.
Origin & Evolution of Life
How Primordial Life On Earth Might Have Replicated Itself
Scientists have created a new type of genetic replication system which demonstrates how the first life on Earth - in the form of RNA - could have replicated itself.
Habitable Zones & Global Climate
Orbital Variations Can Trigger Snowball States In Habitable Zones Around Sunlike Stars
Aspects of an otherwise Earthlike planet's tilt and orbital dynamics can severely affect its potential habitability -- even triggering abrupt "snowball states" where oceans freeze and surface life is impossible, according to new research from astronomers at the University of Washington.
Biosignatures & Paleobiology
Using Deep Space Climate Observatory Measurements to Study the Earth as An Exoplanet
Even though it was not designed as an exoplanetary research mission, the Deep Space Climate Observatory (DSCOVR) has been opportunistically used for a novel experiment, in which Earth serves as a proxy exoplanet.
Mars
Modeling Martian Atmospheric Losses over Time: Implications for Exoplanetary Climate Evolution and Habitability
In this Letter, we make use of sophisticated 3D numerical simulations to assess the extent of atmospheric ion and photochemical losses from Mars over time.
Europa
Old Data Reveal New Evidence of Europa Plumes
Scientists re-examining data from an old mission bring new insights to the tantalizing question of whether Jupiter's moon Europa has the ingredients to support life.
Astrobiology (general)
Could A Multiverse Be Hospitable To Life?
A Multiverse - where our Universe is only one of many - might not be as inhospitable to life as previously thought, according to new research.
Biosignatures & Paleobiology
Atmospheric Seasons Could Signal Alien Life
The hunt for life in these places, which are impossible to visit in person, will begin with a search for biological products in their atmospheres.
Habitable Zones & Global Climate
A Methane Extension to the Classical Habitable Zone
The habitable zone (HZ) is the circumstellar region where standing bodies of liquid water could exist on the surface of a rocky planet. Conventional definitions assume that CO2 and H2O are the only greenhouse gases.
