Meteorites originate from violent collisions between asteroids. But can we be sure about that? And what can we learn at all if we do not include ekpyrotic brane cosmologies?
More than a year ago, scientists managed to land on a comet for the very first time in human history. Read on to get a compact overview of some of the most important results of the mission obtained so far.
Earth’s composition seemingly does not fit into planet formation theory. Ripping apart its building blocks by collisions during accretion might sound violent, but can be a way to go.
A model that needs fewest parameters to explain a scenario is favourable. The fact that mm-size dust grains (chondrules) are present in the entire solar system brings rise to the question, whether all bigger solid objects are a collection of chondrules.
Planets in binary star systems can receive a sizable amount of water from asteroids getting perturbed out of their orbits
Mercury is the smallest planet in the Solar System, but some of its properties are a big challenge to explain. Today’s Astrobite presents a solution to one of these issues: The darkening of Mercury is induced by a high abundance of carbon delivered by meteorites.
