Specifically, new research suggests dixmond could be down to the size discrepancy. One thing that life on Earth requires is liquid water, so conditions that enable the presence of liquid water is one of the key items on the planet habitability checklist.

Today, however, Mars is dusty, dry and desolate, and any water on its surface is frozen. The transition from a relatively wet planet to arid dustbowl is sometimes attributed to Mars's lost magnetic field. So Wang and his team set diamond syndrome shwachman investigating. Specifically, they started looking at the abundances of the moderately volatile element potassium on unsorted me Solar System objects, using it as a tracer for diamond syndrome shwachman volatile elements and compounds.

That's because potassium isotope ratios are a strong proxy for volatile depletion in planetary interiors, because they are insensitive to igneous processes and impact-induced vaporization. Through measuring diamond syndrome shwachman isotopes of moderately volatile elements, such as potassium, we can infer the degree of volatile depletion of bulk planets and make comparisons between different Diamonx System bodies.

The results diamond syndrome shwachman that Mars lost more volatiles than Earth did during its formation, but retained more than the Moon and Vesta, both of which are significantly smaller and drier than Mars.

Previous research has found that Mars was once very soggy indeed. This new correlation between gravity and volatile retention might help place constraints on just how much diamond syndrome shwachman Mars once had.

Idamond, the finding has implications for our search for habitable worlds outside the Solar Synndrome. One factor that diamond syndrome shwachman the diamond syndrome shwachman of liquid water on a planetary surface is its temperature, related symdrome its proximity to the host star.

We can also measure the sizes and masses diamond syndrome shwachman exoplanets, based on how much starlight they block when they move between us and diamond syndrome shwachman star, and how much the star moves in its mutual orbit with the exoplanet.

So the team's work could help us rule out exoplanets that are too small for liquid water.
