Modeling The Corona And XUV Emission Of The Sun And Sun-like Stars 
The X-ray and extreme-ultra-violet (EUV) emissions from the low-mass stars significantly affect the evolution of the planetary atmosphere. It is, however, observationally difficult to constrain the stellar high-energy emission because of the interstellar extinction.

The Give And Take Of Mega-flares From Stars
The long relationships between stars and the planets around them - including the Sun and the Earth - may be even more complex than previously thought. This is one conclusion of a new study involving thousands of stars using NASA's Chandra X-ray Observatory.

Possibilities for an Aerial Biosphere in Temperate Sub Neptune-Sized Exoplanet Atmospheres
The search for signs of life through the detection of exoplanet atmosphere biosignature gases is gaining momentum. Yet, only a handful of rocky exoplanet atmospheres are suitable for observation with planned next-generation telescopes.
Climate
Microbes In Earth's Ocean Play An Important Role In Moderating Earth's Temperature
Methane is a strong greenhouse gas that plays a key role in Earth's climate. Anytime we use natural gas, whether we light up our kitchen stove or barbeque, we are using methane.
Biosignatures & Paleobiology
A Large-scale Approach to Modelling Molecular Biosignatures: The Diatomics
This work presents the first steps to modelling synthetic rovibrational spectra for all molecules of astrophysical interest using the new code Prometheus.
International Space Station
Space Botany and Biology Studies Under Way On The ISS
The orbiting lab is hosting a variety of life forms to help researchers understand how weightlessness affects biology. Observations provide insights often advancing health and improving conditions for humans on and off the Earth.
Fossils
Fossil Secret May Shed Light On The Diversity Of Earth's First Animals
A large group of iconic fossils widely believed to shed light on the origins of many of Earth's animals and the communities they lived in may be hiding a secret.
SETI
Strategies For Maximizing Detection Rate In Radio SETI
The Search for Extraterrestrial intelligence (SETI) is a scientific and cultural effort seeking evidence of intelligent life beyond earth. Radio SETI observes the radio spectrum for ''technosignatures" that could be produced by an advanced ET society.

Microscopic Superheroes to Help Protect Astronaut Health in Space
It's a classic superhero tale: Inconspicuous, underestimated, our hero is revealed to have powers beyond imagination! The hottest and coldest environments on Earth, decades without water, the powerful radiation of space - none of it is any match for... the tardigrade!
Biochemistry
Mechanochemical Peptide Bond Formation Behind The Origins Of Life
The presence of amino acids on the prebiotic Earth is widely accepted, either coming from endogenous chemical processes or being delivered by extraterrestrial material. On the other hand, plausibly prebiotic pathways to peptides often rely on different aqueous approaches where condensation of amino acids is thermodynamically unfavorable.
Microbiology
Solving An Underground Mystery About Where Microbes Live
Though it might seem inanimate, the soil under our feet is very much alive. It's filled with countless microorganisms actively breaking down organic matter, like fallen leaves and plants, and performing a host of other functions that maintain the natural balance of carbon and nutrients stored in the ground beneath us.
