Dinosaurs’ Apparent Decline Prior To Asteroid May Be Due To A Poor Fossil Record
The idea that dinosaurs were already in decline before an asteroid wiped most of them out 66 million years ago may be explained by a worsening fossil record from that […]
Life Recovered Rapidly After The Chicxulub Impact – A Hydrothermal System May Have Helped
About 66 million years ago, an asteroid slammed into the planet, wiping out all non-avian dinosaurs and about 70% of all marine species.
Ray Ionisation Of A Post-impact Early Earth Atmosphere: Solar Cosmic Ray Ionisation Must Be Considered In Origin-of-life Scenarios
Cosmic rays (CR), both solar and Galactic, have an ionising effect on the Earth’s atmosphere and are thought to be important for prebiotic molecule production. In particular, the H2-dominated atmosphere […]
Orbit, Meteoroid Size, And Cosmic Ray Exposure History Of The Aguas Zarcas CM2 Breccia
The Aguas Zarcas (Costa Rica) CM2 carbonaceous chondrite fell during night time in April 2019. Security and dashboard camera video of the meteor were analyzed to provide a trajectory, lightcurve, […]
The Atmospheric Entry of Cometary Impactors
Cometary impacts play an important role in the early evolution of Earth, and other terrestrial exoplanets.
Impacts Into Titan’s Methane-clathrate Crust As A Source Of Atmospheric Methane
Titan is the only icy satellite in the solar system with a dense atmosphere. This atmosphere is composed primarily of nitrogen with a few percent methane, which supports an active, […]
An Upper Limit on the Interstellar Meteoroid Flux at Video Sizes from the Global Meteor Network
Material arriving at our solar system from the Galaxy may be detected at Earth in the form of meteors ablating in our atmosphere. Here we report on a search for […]
Spectral Effects of Shock Darkening On Ordinary Chondrite and Howardite, Eucrite, And Diogenite Meteorites
Impacts are the most ubiquitous processes on planetary bodies in our solar system. During these impact events, shock waves can deposit enough energy to produce shock-induced darkening in the target […]
Deep Mantle-Atmosphere Coupling And Carbonaceous Bombardment: Options For Biomolecule Formation On Aan Oxidized Early Earth
Understanding what environmental conditions prevailed on early Earth during the Hadean eon, and how this set the stage for the origins of life, remains a challenge.
