Space Technology for Directly Imaging and Characterizing Exo-Earths 
The detection of Earth-like exoplanets in the habitable zone of their stars, and their spectroscopic characterization in a search for biosignatures, requires starlight suppression that exceeds the current best ground-based performance by orders of magnitude.
Astrobiology (general)
The Epistemological Status of Astrobiology: A Problematic Case of Integration of Scientific Disciplines
Astrobiology is a scientific discipline that studies life in the Universe. We call it a discipline and not a science because some authors have cast doubts over its epistemological status by calling it 'a science without an object of study'.
Mars
More Evidence of Water on Early Mars
River deposits exist across the surface of Mars and record a surface environment from over 3.5 billion years ago that was able to support liquid water at the surface.
Astrochemistry
Could Interstellar Ice Provide The Answer To Birth Of DNA?
Researchers at the University of York have shown that molecules brought to earth in meteorite strikes could potentially be converted into the building blocks of DNA.
Fossils
Half-a-billion-year-old Fossils Shed light Animal Evolution on Earth
Scientists have discovered traces of life more than half-a-billion years old that could change the way we think about how all animals evolved on earth.
Proxima Centauri b
Was Proxima Centauri Captured by Alpha Centauri A and B?
The nearest stellar system consists of the stars Proxima, alpha Centauri A and B and at least one planet Proxima b. The habitability of Proxima b and any other planets are likely to be significantly influenced by the orbital evolution of the system.
Extrasolar Planets
Photosynthesis Under Light Conditions Different from Earth's
M-dwarfs or red dwarfs are small (0.5-0.1 solar-mass) and cool ( ~3,000 kelvin) stars and are abundant in the universe.
Astronomy
Space Telescope Designed to Directly Image the Habitable Zone of Alpha Centauri
The scientific interest in directly image and identifying Earth-like planets within the Habitable Zone (HZ) around nearby stars is driving the design of specialized direct imaging mission such as ACESAT, EXO-C, EXO-S and AFTA-C.

The Breakthrough Listen Search for Intelligent Life: 1.1-1.9 GHz observations of 692 Nearby Stars
We report on a search for engineered signals from a sample of 692 nearby stars using the Robert C. Byrd Green Bank Telescope (GBT), undertaken as part of the Breakthrough Listen Initiative search for extraterrestrial intelligence.
Proxima Centauri b
Do-It-Yourself Science -- Is Proxima c Hiding In This Graph?
Is Proxima c hiding in this graph?
Polar Research
Secret Life May Thrive In Warm Caves Under Antarctica's Glaciers
A new study led by ANU has found that animals and plants may live in warm caves under Antarctica's glaciers.
