It goes like this: the sun began as a protostar in its "solar nebula" over 4.5 billion years ago. Over the course of several million years, the planets emerged from this nebula and it dissipated away.

Have you ever wondered why all the planets in our solar system orbit the Sun in roughly the same flat plane? This fascinating ...

Our solar system is the only one known to have life inside. While scientists are searching for water in other planets, a new ...

Astronomers call the collapsing cloud that ultimately became the solar system the “solar nebula.” As the nebula contracted, it had to rotate faster to conserve its angular momentum (just like ...

The early solar system had a sun-centered cloud of gas and dust called the solar nebula, which most researchers think dispersed after one million or two million years, Sharp says. For decades, ...

They are found in meteorites but not in terrestrial rocks, and they are among the first solids that formed in the cloud of gas and dust called the solar nebula that swirled around the young sun ...

The shock wave from an exploding star likely helped trigger the formation of our solar system, according to a new 3D computer model, researchers say. The solar system is thought to have coalesced ...

Discover how a giant interstellar cloud known as the solar nebula gave birth to our solar system and everything in it. The solar system as we know it began life as a vast, swirling cloud of gas and ...

Chondritic meteorites (chondrites) are some of the oldest rocks in our solar system, forming 4.5 billion years ago. Therefore ...

“Our high 3He/4He measurements imply that gases, presumably inherited from the solar nebula during solar system formation, are better preserved in Earth than previously thought,” he sai ...
