The Solar System, our cosmic home, is a fascinating and dynamic region of space filled with a diverse range of planets, moons ...

“The theory that best explained this energetic early phase of the solar system indicated that it was caused primarily by the dissipation of the so- called solar nebula,” says coauthor Maria ...

A leading idea about how our solar system formed is the solar nebula theory, in which a cloud of rotating debris condensed to form the Sun and planets over billions of years. Olson’s team ...

Surprisingly, the krypton isotopes in the meteorite correspond to those originating from meteorites, not the solar nebula. That means that meteorites were delivering volatile elements to the forming ...

The main hypothesis for the formation of such as is that they initially acquired volatiles — such as water and elements which vaporize at low temperatures — from the solar nebula, the swirling ...

A rare form of helium may have flooded Earth’s core during the planet’s formation in the hot, early stage of our solar system, according to a study published this week. Measuring that helium ...

But there is an older and more controversial theory: The solar nebula itself may have delivered primordial helium-3 into the planet’s core, says stable isotope geochemist Zachary Sharp, director ...
