Organic Matter in Cometary Environments
Comets contain primitive material leftover from the formation of the Solar System, making studies of their composition important for understanding the formation of volatile material in the early Solar System.

Prebiotic chemicals—amino acid and phosphorus—in the coma of comet 67P/Churyumov-Gerasimenko
The detection of glycine and phosphorus in the coma of 67P shows that comets contain all ingredients to help spark life on Earth. The importance of comets for the origin of life on Earth has been advocated for many decades.

Volatile Species in Comet 67P/Churyumov-Gerasimenko: Investigating the Link from the ISM to the Terrestrial Planets [PDF]
Comets contain abundant amounts of organic and inorganic species. Many of the volatile molecules in comets have also been observed in the interstellar medium and some of them even with similar relative abundances, indicating formation under similar ...

The Formation of a Rubble Pile Asteroid: Insights from the Asteroid Ryugu
The Hayabusa2 mission returned primitive samples from the C-type asteroid Ryugu to Earth. The C-type asteroids hold clues to the origin of Earth’s water and the building blocks of life.

The European Space Agency’s Comet Interceptor lies in wait
The European Space Agency (ESA) recently selected Comet Interceptor as its first ‘fast’ (F-class) mission. It will be developed rapidly to share a launch with another mission and is unique, as it will wait in space for a yet-to-be-discovered comet.

Effects of the Planar Galactic Tides and Stellar Mass on Comet Cloud Dynamics
We report the first results of a research program to explore the sensitivity of the orbits of Oort cloud comets to changes in the strength of the Galactic tides in the plane of the disk and also to changes in the mass of the host star.

Evaluation of Genotoxic and Cytotoxic Effects of Gluten in Male Albino Mice
Gluten is a protein commonly found in daily diets in the form of wheat, barley, rye, and other grains. It serves as the structural component in flour, providing the binding qualities that maintain the shape and texture of food items.

Photometry of comet C/2011 L4 (PANSTARRS) at 4.4 - 4.2 AU heliocentric distances
We present an analysis of the photometric data of comet C/2011 L4 (PANSTARRS) observed at heliocentric distance of 4.4 - 4.2 AU. The comet C/2011 L4 (PANSTARRS) shows one significant activity, despite of its quite large heliocentric distance.
