The surface and subsurface of worlds beyond Mars remain largely unexplored. Yet these worlds hold keys to fundamental questions in planetary science – from potentially habitable subsurface oceans on icy […]

ALMA Reveals Interstellar Comet 3I/ATLAS Formed in a Far Colder World Than Our Own
New observations from the Atacama Large Millimeter/submillimeter Array (ALMA) have yielded the first-ever measurement of deuterated water — also known as semi-heavy water — in an interstellar object. The discovery […]
Secular Light Curve of Exocomet 3I/ATLAS, and its Location on a Comet Evolutionary Diagram
In this work we will create the Secular Light Curve (SLC) of exocomet 3I/ATLAS, using the SLC-Methodology (Ferrin 2010-2023). The SLCs give a throve of new information and allow the […]
From Dust to Planets — A Chemical Perspective
Chemical and chronological information preserved in meteorites permits the reconstruction of events and processes in the solar nebula from the formation of the first solids to the accretion of planetary […]
Interstellar Comet Reveals Methane On Its Journey Through Our Solar System
Interstellar comet 3I/ATLAS is now on its way out of our solar system, never to return.
Simulating The Interplay Between The Snowline Pebble Flux And Ongoing Planet Formation And Migration
Pebble drift plays a central role in modern planet formation models. In this work we carry out planet formation simulations (including pebble accretion and migration) for a range of disc […]
Subaru Telescope Captures Interstellar Comet 3I/ATLAS Composition Change
The Subaru Telescope observed the interstellar comet 3I/ATLAS on January 7, 2026 (UT), after it made its closest approach to the Sun. By observing colors in the coma around the […]
Analysing The Sample Preparation Process In Meteorites And Its Impact On The Pretreatment Of Returned Samples To Earth
The study of meteorites is important for planetary sciences because, among other things, it can provide information about the geochemical composition of their celestial body of origin. Often, subsample preparation […]
Distribution Of Extraterrestrial Nucleobases, Other N-heterocycles, And Their Precursors In A Sample From Asteroid Bennu
The recent discovery of all five canonical nucleobases in samples from Bennu provides compelling evidence that some of life’s ingredients were synthesized abiotically in the parent body of this asteroid […]
The Zhamanshin Impact Event: Potential Implications for Environmental Responses and Biological Linkages on Earth and Beyond
At least one large-body (diameter > 1.1 km) hypervelocity cratering event occurred during ~ 0.8-0.90 Ma (Zhamanshin, Kazakhstan) in the Middle Pleistocene Transition period.
