North Pole Dome (Pilbara Craton, Western Australia) contains unique geological analogs to early Earth and Mars.
An international team of paleontologists has spent more than 15 years excavating and studying fossils from Africa to expand our understanding of the Permian, a period of Earth’s history that […]
Evidence for the beneficial role of impacts in the creation of urable or habitable environments on Earth prompts the question of whether meteorite impacts could play a similar role at […]
Giant impacts were common in the early evolution of the Solar System, and it is possible that Venus also experienced an impact. A giant impact on Venus could have affected […]
Understanding the mechanisms of protein preservation in extreme environments is essential for identifying potential molecular biosignatures on Mars.
![The region in which dark matter impacts may leave detectable surface features on Ganymede. Gray regions correspond to existing constraints [33, 35, 37]. The light purple region is the region in which the dark matter has sufficient initial energy to penetrate through the 12 km conductive ice layer on Ganymede’s surface. The darker purple region corresponds to when the dark matter penetrates the entirety of Ganymede, leaving both an entrance and exit wound. Rough estimates for the approximate number of craters and crater radius from Eqs. 1 and 13 are provided on the top and right axes respectively, rounded to one significant figure for readability. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/08/Dark-Wounds-On-Icy-Moons.png?resize=1200%2C720&ssl=1)
Dark matter in the form of macroscopic composites is largely unconstrained at masses of ∼1011−1017 g. In this mass range, dark matter may collide with planetary bodies, depositing an immense […]
Gossans are formed through the oxidation of sulfide ore deposits by fluids, such as meteoric water or hydrothermal solutions, leading to locally acidic conditions.
During a hypervelocity impact, both the impactor and target materials evaporate, generating an impact vapor plume with temperatures reaching several thousand K.
The orbital regime of a terrestrial planet plays a significant role in shaping its atmospheric dynamics, climate, and hence potential habitability.
This work describes new dynamical simulations of terrestrial planet formation. The simulations started at the protoplanetary disk stage, when planetesimals formed and accreted into protoplanets, and continued past the late […]
