The formation of Earth is a cosmic tale that stretches back over 4.5 billion years, from the swirling gases and dust of the solar nebula to the planet we know today. But how exactly did Earth come to ...

Regardless of the true amount, though, the helium leak lends credence to the solar nebula theory, like a fart of truth that our world has been slowly letting go over 4 billion years.

The new research adds further clues to the mystery surrounding Earth's formation, lending additional evidence to the theory that our planet formed inside the solar nebula.

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 ...

The planet must have acquired atmosphere from the solar nebula, after the magma ocean cooled, to prevent substantial mixing between interior chondritic gases and atmospheric solar gases.

THE hypothesis of Kant and Laplace that the solar system originated by a gradual process from the contraction of a rotating nebula has become more and more improbable as the theory of such a ...

THE object of the present treatise is to establish in a modified form the nebular theory of Laplace, by the introduction of some original views which have long occupied the attention of the author ...

All cells on Earth are made of phospholipid membranes. Now astronomers have found the component molecules in interstellar space.

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 ...
