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.
Earth’s oceans may have originated mainly from accreted impactors. But do planets in other systems experience the same water delivery mechanism? Or do they even get more water than our world? Find out why you would want to think about this and what the consequences might be.

Water is essential for life, but where does it come from? Read on and learn that a significant amount is inherited from the interstellar medium.
Habitable zone estimations take the climate regulation of the carbon cycle into account. But are we drawing the edges of the habitable zone too wide?
We have one canonical idea of what life looks like on Earth: nitrogen, water, carbon dioxide. But would this be true on another world? When looking for life in the atmospheres of exoplanets, we might want to consider searching for something completely different.
