Discover how a giant interstellar cloud known as the solar nebula gave birth to our solar system and everything in it.

Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a protoplanetary disk out of which the planets, moons, asteroids, and other small Solar System …

Apr 12, 2025 · Dive into solar system formation. Learn how the sun was made and how our planets were born from cosmic dust.

Dec 20, 2020 · The formation of the solar system is a challenging puzzle for modern astronomy and a terrific tale of extreme forces operating over immense timescales. Let's dig in.

Oct 10, 2025 · The favoured theory proposes that the solar system formed from a solar nebula, where the Sun was born out of a concentration of kinetic energy and heat at the centre, while …

Oct 3, 2025 · The Solar system formed through condensation from big clouds of gas and dust called nebulae after a supernova, or the explosion of a large star. Planets move around the …

All the planets in our Solar System started out as clouds of gas and dust orbiting a new star—the Sun. Over time, all that gas and dust began to stick together and slowly built up into balls.

Aug 24, 2025 · The formation of the Solar System is believed to have begun about 4.6 billion years ago from a giant cloud of gas and dust known as the solar nebula. This cloud collapsed …

The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated …

This illustration shows the steps in the formation of the solar system from the solar nebula. As the nebula shrinks, its rotation causes it to flatten into a disk.
