Impact-induced hydrothermal systems have the potential to sustain long-lived aqueous environments throughout the history of Mars, yet their nature and distribution are not well-understood.
1-4 September 2025, Nördlingen, Germany We are pleased to share an exciting invitation to the conference, “Impacts and their role in the origin and evolution of life“ which will be […]
Carbon-containing meteorites look like they had less severe impacts than those without carbon because the evidence was blasted into space by gases produced during the impact. The Kobe University discovery […]
Due to their isotopic similarity to terrestrial rocks across a range of elements, the meteorite group that is thought to best represent Earth’s building blocks is the enstatite chondrites (ECs).
University of Oxford researchers have helped overturn the popular theory that water on Earth originated from asteroids bombarding its surface. Instead, the material which built our planet was far richer […]
Scientists have hypothesized since the 1960s that the Sun is a source of ingredients that form water on the Moon. When a stream of charged particles known as the solar […]
![Orbital distribution of 7,982 impacts detected by EDMOND, CAMS, GMN, FRIPON, and EFN networks. Each impact is estimated to be equal to or greater than 10 g (diameter ⪆2 cm) at the top of the atmosphere. Orbital distribution is normalized to the impact probability, as calculated using the method of Pokorn`y and Vokrouhlick`y [96]. Despite this, there still exists a concentration of meteoroids on orbits with q∼1 au -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/04/Perihelion-History-And-Atmospheric-Survival.png?resize=1200%2C721&ssl=1)
Models predict that more than half of all impacting meteoroids should be carbonaceous, reflecting the abundance of carbon-rich asteroids in the main belt and near-Earth space.
An international team of researchers may have answered one of space science’s long-running questions – and it could change our understanding of how life began.
We report on the formation of membranous protocells by self-assembly of lipids on micrometeorites, the extraterrestrial particles that have been continuously reaching the surface of the Earth ever since its […]
ANSMET is excited at the possibility of a field season coming in December of 2025! We do not have the full go ahead from NSF yet, but we are holding […]
