"This material is primitive material -- it's the very first material of the solar nebula," or the cloud of interstellar dust and gas that formed the planets of our system, said Jaumann.
The results imply that to absorb these vital compounds, a planet must reach a certain size -- the size of Mars or a little larger -- before the solar nebula dissipates.
The new study challenges widely-accepted ideas about hydrogen in Earth's water by suggesting the element partially came from clouds of dust and gas remaining after the Sun's formation, called the solar nebula.
A study of ancient meteorites has refined the date for the dissolution of the solar nebula, the cloud of dust and gas from which the planets formed.
By re-creating conditions in the solar nebula, the swirl of gas that coalesced to form our star, the planets and the remnant rocky debris that circles the Sun as asteroids, the researchers demonstrated that a simple chemical reaction, governed by known physical principles, can generate silicate dust with oxygen anomalies that match those found in the oldest rocks in the solar system.
