SETI
Concepts For Future Missions To Search For Technosignatures 
New and unique opportunities now exist to look for technosignatures (TS) beyond traditional SETI radio searches, motivated by tremendous advances in exoplanet science and observing capabilities in recent years.

Implications Of An Improved Water Equation Of State For Water-rich Planets
Water (H2O), in all forms, is an important constituent in planetary bodies, controlling habitability and influencing geological activity.

International Space Station Archives Fuel New Scientific Discoveries
When scientists complete an experiment aboard the International Space Station, the ramifications of that work have just begun. NASA carries on a legacy of decades of biological research data, fueling new discoveries long after studies wrap up in space.

Discovery of Allenyl Acetylene, H2CCCHCCH, in TMC-1. A Study Of The Isomers Of C5H4
We present the discovery in TMC-1 of allenyl acetylene, H2CCCHCCH, through the observation of nineteen lines with a signal-to-noise ratio ~4-15. For this species, we derived a rotational temperature of 7 +/- 1 K and a column density of (1.2 +/- 0.2)e13 cm-2.

Microbes Deep Beneath The Seafloor Survive On The Byproducts Of Water Molecule Irradiation
A team of researchers from the University of Rhode Island's Graduate School of Oceanography and their collaborators have revealed that the abundant microbes living in ancient sediment below the seafloor are sustained primarily by chemicals created by the natural irradiation of water molecules.

Asteroid Dust Found In Crater Closes Case Of Dinosaur Extinction
Researchers believe they have closed the case of what killed the dinosaurs, definitively linking their extinction with an asteroid that slammed into Earth 66 million years ago by finding a key piece of evidence: asteroid dust inside the impact crater.

Oxygen As A Control Over 2.4 Billion Years Of Earth's Atmospheric Evolution
Since the formation of the terrestrial planets, atmospheric loss has irreversibly altered their atmospheres, leading to remarkably different surface environments - Earth has remained habitable while Venus and Mars are apparently desolate.

The Rotational And Divergent Components Of Atmospheric Circulation On Tidally Locked Planets
Tidally locked exoplanets likely host global atmospheric circulations with a superrotating equatorial jet, planetary-scale stationary waves and thermally-driven overturning circulation.

How To Have Memories Without Having A Brain
Having a memory of past events enables us to take smarter decisions about the future.

Milky Way May Be Swarming With Planets With Oceans And Continents Like Earth's
Astronomers have long been looking into the vast universe in hopes of discovering alien civilisations. But for a planet to have life, liquid water must be present.
Mars
Life From Earth Could Temporarily Survive On Mars
Some microbes on Earth could temporarily survive on the surface of Mars, finds a new study by NASA and German Aerospace Center scientists.
