Uncovering Exotic Molecules Of Potential Astrochemical Interest

Looking at the night sky, one's thoughts might be drawn to astrochemistry. What molecules inhabit the vast spaces between the stars? Would we see the same molecules that surround us here on Earth? Or would some of them be more exotic--something rarely observed or even unknown?

Life On Venus? First We Need To Know More About Molecules In The Atmosphere

The search for life on other planets has received a major boost after scientists revealed the spectral signatures of almost 1000 atmospheric molecules that may be involved in the production or consumption of phosphine, a study led by UNSW Sydney revealed.

3D Convection-resolving Model Of Temperate, Tidally-locked Exoplanets

A large fraction of known terrestrial-size exoplanets located in the Habitable Zone of M-dwarfs are expected to be tidally-locked. Numerous efforts have been conducted to study the climate of such planets, using in particular 3-D Global Climate Models (GCM).

Amounts Of Organic Molecules In Planetary Systems Differ From Early On

An international group of scientists led by the RIKEN Cluster for Pioneering Research have studied the chemical composition of 50 protoplanetary-disk forming regions in the Perseus Molecular Cloud, and found that despite being in the same cloud, the amounts of complex organic molecules they contain are quite different.

Long-awaited Review Reveals Journey Of Water From Interstellar Clouds To Habitable Worlds

Dutch astronomer Ewine van Dishoeck (Leiden University, the Netherlands), together with an international team of colleagues, has written an overview of everything we know about water in interstellar clouds thanks to the Herschel space observatory.

Earth's Crust Mineralogy Drives Hotspots For Intraterrestrial Life

Below the verdant surface and organic rich soil, life extends kilometers into Earth's deep rocky crust. The continental deep subsurface is likely one of the largest reservoirs of bacteria and archaea on Earth, many forming biofilms - like a microbial coating of the rock surface.

More Than 5,000 Tons Of Extraterrestrial Dust Fall To Earth Each Year

Every year, our planet encounters dust from comets and asteroids. These interplanetary dust particles pass through our atmosphere and give rise to shooting stars. Some of them reach the ground in the form of micrometeorites.
