HKUST Unlock Genomic Secrets of Deep-sea Tubeworm 
Researchers from The Hong Kong University of Science and Technology (HKUST) have decoded the chromosomal-level genome of a deep-sea gutless tubeworm and the genome of its co-living "partner" - a kind of bacteria that provide nutrients they generate from inorganic compounds to the worm for the first time, explaining how the pair adapts to the extreme habitat.

The Keck Planet Imager and Characterizer: A Dedicated Single-mode Fiber Injection Unit For High Resolution Exoplanet Spectroscopy
The Keck Planet Imager and Characterizer (KPIC) is a purpose-built instrument to demonstrate new technological and instrumental concepts initially developed for the exoplanet direct imaging field.
Microbiology
Selenium May Support Deep Microbial Life In Earth's Continental Crust
International drilling efforts over the last decades into the seafloor have provided increasing evidence for the existence of an extensive deep biosphere below the seafloor.
Biosignatures & Paleobiology
Assessment of Ammonia as a Biosignature Gas in Exoplanet Atmospheres
Ammonia (NH3) in a terrestrial planet atmosphere is generally a good biosignature gas, primarily because terrestrial planets have no significant known abiotic NH3 source.
Astrogeology
The Reflectance Spectra of CV-CK Carbonaceous chondrites from the Near Infrared to the Visible
Carbonaceous chondrite meteorites are so far the only available samples representing carbon-rich asteroids and in order to allow future comparison with samples returned by missions such as Hayabusa 2 and OSIRIS-Rex, is important to understand their physical properties.
Fossils
Cellular Remains in A ~3.42-billion-year-old Subseafloor Hydrothermal Environment
While Earth may have been a habitable planet long before the Paleoarchean Era [3.6 to 3.2 billion years ago (Ga)], as rocks of this age retain a diversity of fossil evidence for life the complexity of life's cellular constituents, range of metabolic pathways, the niches it occupied locally, and global diversity of its habitats remain largely unknown.
Ganymede
Hubble Finds First Evidence of Water Vapor at Jupiter's Moon Ganymede
For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates -- that is, turns from solid to gas.

How Ethane-consuming Archaea Pick Up Their Favorite Dish
U.S. National Science Foundation-funded researchers have discovered ethane-degrading microbes at hydrothermal vents in the Gulf of California's Guaymas Basin at a water depth of 2,000 meters. The results are published in the journal Science.
Callisto
A Tenuous, Collisional Atmosphere On Callisto
A simulation tool which utilizes parallel processing is developed to describe molecular kinetics in 2D, single-and multi-component atmospheres on Callisto.
Mars
Better Understanding Of Earth's Atmospheric Chemistry From Studying Mars?
A new analysis of data from ESA's Mars Express mission has revealed that our knowledge of the way these atmospheric gases interact with each other is incomplete.
