SETI
Arecibo Observatory, Google and a New Message Challenge 
In 1974, the Arecibo Observatory made history by beaming the most powerful radio message into deep space ever made.

Life Before Fermi - Back to the Solar System
The existence of intelligent, interstellar traveling and colonising life is a key assumption behind the Fermi Paradox.

Rain Brings Death To Mars-like Atacama Desert
When rains fell on the arid Atacama Desert, it was reasonable to expect floral blooms to follow. Instead, the water brought death.

Prospects For Detecting The Astrometric Signature of Barnard's Star b
A low-amplitude periodic signal in the radial-velocity (RV) time-series of Barnard's Star was recently attributed to a planetary companion with a minimum mass of ∼3.2 M⊕ at an orbital period of ∼233 days.

A Super-Earth Planet Candidate Orbiting at the Snow-line of Barnard's Star
At a distance of 1.8 parsecs, Barnard's star (Gl 699) is a red dwarf with the largest apparent motion of any known stellar object.
Astrochemistry
Heliospheric Modulation of the Interstellar Dust Flow on to Earth
Aims. Based on measurements by the Ulysses spacecraft and high-resolution modelling of the motion of interstellar dust (ISD) through the heliosphere we predict the ISD flow in the inner planetary system and on to the Earth.

A Super-Earth Has Been Discovered Orbiting Barnard's Star
The nearest single star to the Sun hosts an exoplanet at least 3.2 times as massive as Earth -- a so-called super-Earth.
Dale Andersen's Field Reports
Astrobiologist Dale Andersen Antarctic Status Report 12 November 2018: Better Weather
"The last two days have been pretty nice weather-wise, and very productive."
Tricorder
A Tricorder From Scotland
A Star Trek-inspired handheld device based on a silicon chip could help make rapid, sophisticated medical diagnostics more accessible to people around the world, scientists say.
Dale Andersen's Field Reports
Astrobiologist Dale Andersen Antarctic Status Report 9 November 2018: Better Weather - For Now
"The weather improved today with sunshine and light winds greeting us this morning, a nice change of pace from the constant pounding we have had the last few days."

Bayesian Deep Learning for Exoplanet Atmospheric Retrieval
Over the past decade, the study of exoplanets has shifted from their detection to the characterization of their atmospheres.
