Galaxies

Galaxies consist of stars, planets, and vast clouds of gas and dust, all bound together by gravity. The largest contain trillions of stars and can be more than a million light-years across. The smallest can contain a few thousand stars and span just a few hundred light-years. Most large galaxies have supermassive black holes at []

18.1: Introduction to the Solar System

The force of gravity exists between all objects in the universe; the strength of the force depends on the mass of the objects and the distance between them. According to this hypothesis, the Sun and the planets of our solar system formed about 4.6 billion years ago from the collapse of a giant cloud of gas and dust, called a nebula.

In Depth | Our Solar System – NASA Solar System Exploration

There are many planetary systems like ours in the universe, with planets orbiting a host star. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a

Learn About the Universe With the James Webb Space Telescope

NASA is launching the largest, most powerful space telescope ever. The James Webb Space Telescope will look back at some of the earliest stages of the universe, gather views of early star and galaxy formation, and provide insights into the formation of planetary systems, including our own solar system.

Solar system

Solar system - Origin, Planets, Formation: As the amount of data on the planets, moons, comets, and asteroids has grown, so too have the problems faced by astronomers in forming theories of the origin of the solar system. In the ancient world, theories of the origin of Earth and the objects seen in the sky were certainly much less constrained by fact. Indeed, a

Solar nebula | Formation, Accretion, Protoplanetary Disk | Britannica

Solar nebula, gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. Swedish philosopher Emanuel Swedenborg in 1734 proposed that the planets formed out of a nebular crust that had surrounded the Sun and then

Planet Formation In Order of Creation

The planets formed in intervals – not altogether, as was previously thought," said Dr. Tagir Abdylmyanov, Associate Professor from Kazan State Power Engineering University in Russia. He believes that the Sun sent out shockwaves in the solar system. The solar system is the eight major planets and their moons in orbit around the Sun.

Formation of The Earth : Earth''s Birth, Timeline and Layering

The formation of the solar system is a dynamic process that resulted in the distinct celestial bodies we observe in our cosmic neighborhood. The inner rocky planets, including Earth, formed closer to the Sun, while the outer gas giants like Jupiter and Saturn formed farther out, where the solar nebula contained more volatile elements.

How our solar system was born

The solar system as we know it began life as a vast, swirling cloud of gas and dust, twisting through the universe without direction or form. About 4.6 billion years ago, this gigantic cloud was transformed into our Sun. The processes that followed gave rise to the solar system, complete with eight planets, 181 moons, and countless asteroids.

Formation and evolution of the Solar System

Artist''s conception of a protoplanetary disk. There is evidence that the formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. [1] 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

OverviewFormationHistorySubsequent evolutionMoonsFutureGalactic interactionChronology

The nebular hypothesis says that the Solar System formed from the gravitational collapse of a fragment of a giant molecular cloud, most likely at the edge of a Wolf-Rayet bubble. The cloud was about 20 parsecs (65 light years) across, while the fragments were roughly 1 parsec (three and a quarter light-years) across. The further collapse of the fragments led to the formation of dense cor

Stars

Astronomers estimate that the universe could contain up to one septillion stars – that''s a one followed by 24 zeros. Our Milky Way alone contains more than 100 billion, including our most well-studied star, the Sun. Stars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements. []
