The exploration of the Saturnian system, and in particular the plumes and subsurface ocean of Enceladus, has been identified as a key science theme for ESA’s Voyage 2050 program.
Experimentally modeling the habitability of extreme ocean world conditions, such as those on Jupiter’s moon: Europa, would benefit from integrated microbe-virus model studies to provide both a microbial model and […]
Northwestern University-led astronomers have discovered salty skies surrounding the universe’s famous “Pink Planet.”
To address the chemistry responsible for life’s emergence, we examine the simple chemicals accessible on early Earth and the processes that could have transformed them. We focus on carbon reduction […]
This review of martian organic geochemistry aims to contextualize recent findings of organic molecules in martian meteorites and from Mars missions within the broader study of origins of life on […]
We report multi-band photometric imaging observations and Monte Carlo dust tail modelling of the interstellar comet 3I/ATLAS covering a wide range of heliocentric distances, from about 4 au pre-perihelion to […]
Editor’s note: If we aspire to mount expeditions to new worlds and then embrace the task of characterizing and quantifying whatever life forms we find, the ability to map and […]
Context. Cosmic noon (z ~ 1-3) marks the peak of the cosmic star-formation rate density, when dust-obscured star formation dominated galaxy growth. Mid-infrared spectroscopy probes the interstellar medium through PAH […]
Four-and-a-half billion years ago, a massive world, possibly as big as the moon or even Mars, orbited our sun before crashing into another celestial body and shattering into rubble.
Background/Objectives: tRNAs, tRNAomes, aminoacyl-tRNA synthetases (AARSs), the first proteins, ribosomes and the genetic code coevolved. We utilize sequence data to reconstruct key steps in establishing the first code on Earth.
