A Radioactive Metal May Be Vital For Building Water Worlds

While we tend to think that Earthís oceans make it a watery planet, itís actually only a tiny fraction of a percent of water by mass. Looking out into the universe, itís clear water is more common than our own planet implies. Some exoplanets can have half their mass as water. So, what causes some planetary systems to stay wet, while others dry out? The answer might be aluminum. Tim Lichtenberg is the lead author of a new study published Feb. 11, in Nature Astronomy. He says that large amo

Do you like Earth's solid surface and life-inclined climate? Thank your lucky (massive) star

Earth's solid surface and moderate climate may be due, in part, to a massive star in the birth environment of the Sun, according to new computer simulations of planet formation.

A radioactive metal may stifle the formation of water worlds

Because it can dry out the building blocks of planets before they merge, radioactive aluminum may play a major role in determining whether a world ends up wet or not.
