Astrochemistry
Chemical Synthesis of PAHs Can Occur at Very Low Temperatures 
Until now, in the scientific community there has been the prevailing view that thermal processes associated exclusively with the combustion and high-temperature processing of organic raw materials such as oil, coal, wood, garbage, food, tobacco underpin the formation of PAHs

Superflares from Young Red Dwarf Stars Imperil Planets
The word "HAZMAT" describes substances that pose a risk to the environment, or even to life itself. Imagine the term being applied to entire planets, where violent flares from the host star may make entire worlds uninhabitable by affecting their atmospheres.
Extrasolar Planets
Warm super-Earths in twin orbits around the mid-type M dwarfs Ross 1020 (GJ 3779) and LP 819-052 (GJ 1265)
We announce the discovery of two planetary companions orbiting around the low mass stars Ross 1020 (GJ 3779, M4.0V) and LP 819-052 (GJ 1265, M4.5V).

Astrobiologist Dale Andersen Antarctic Status Report 17 October 2018: Preparing To Depart
Tomorrow (17 October) my team and I will depart for Cape Town, South Africa the first leg in our journey to Lake Untersee in the Mountains of Queen Maud Land, Antarctica.
SETI
Science with an ngVLA: SETI Searches for Evidence of Intelligent Life in the Galaxy
Radio SETI experiments aim to test the hypothesis that extraterrestrial civilizations emit detectable signals from communication, propulsion, or other technologies.
Astrochemistry
Science with an ngVLA: Prebiotic Molecules
Extraterrestrial amino acids, the chemical building blocks of the biopolymers that comprise life as we know it on Earth are present in meteoritic samples.

Algorithm Takes Search for Habitable Planets to the Next Level
An international team of scientists, including high performance computing (HPC) experts from the King Abdullah University for Science and Technology (KAUST), astronomers from the Paris Observatory and the National Astronomical Observatory of Japan (NAOJ), in collaboration with NVIDIA, is taking the search for habitable planets and observation of first epoch galaxies to the next level.
Europa
Condition For The Deflection of Vertical Cracks at Dissimilar Ice Interfaces On Europa
The surface of Europa contains many quasi-circular morphologies called lenticulae. Although the formation mechanism of lenticulae is not understood, sill intrusion from the subsurface ocean is one promising hypothesis.
Astrobiology (general)
Life-Detection Technologies for the Next Two Decades
Since its inception six decades ago, astrobiology has diversified immensely to encompass several scientific questions including the origin and evolution of Terran life, the organic chemical composition of extraterrestrial objects, and the concept of habitability, among others.

Harvesting Solar Fuels Through a Bacterium's Unusual Appetite For Gold
A bacterium named Moorella thermoacetica won't work for free. But UC Berkeley researchers have figured out it has an appetite for gold. And in exchange for this special treat, the bacterium has revealed a more efficient path to producing solar fuels through artificial photosynthesis.
Moons and Icy Worlds
Ganymede Shows Evidence of Past Strike-slip Faulting
A recently published study led by researchers at the University of Hawai'i at Manoa School of Ocean and Earth Science and Technology reveals Ganymede, an icy moon of Jupiter, appears to have undergone complex periods of geologic activity, specifically strike-slip tectonism, as is seen in Earth's San Andreas fault.
