Nebular Hypothesis: According to this theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust. ... This could have been the result of a passing star, or shock waves from a supernova, but the end result was a gravitational collapse at the center of the cloud.

Elements are subdivided into several categories based on where they originated from: The Big Bang, Cosmic Rays, Large Stars, Small Stars, Supernovae, and Man-Made labs.

Nebular hypothesis is a theory which states that the whole solar system starts as a large cloud of gas that contracts under self-gravity. ... Meanwhile, Protoplanet Hypothesis is the current working model for the formation of the solar system..

First, stars fuse hydrogen atoms into helium. Helium atoms then fuse to create beryllium, and so on, until fusion in the star's core has created every element up to iron. Iron is the last element stars create in their cores, and a kiss of death for any star with the the mass to make it to this point.

Stretching roughly 4 to 5 light-years, the Pillars of Creation are a fascinating but relatively small feature of the entire Eagle Nebula, which spans 70 by 55 light-years.

Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Scientists think supermassive black holes formed at the same time as the galaxy they are in.

The Endosymbiont Hypothesis The first cells are thought to have been prokaryotes, based on microfossils and on the fact that prokaryotes are simpler than eukaryotes. Eukaryotes are now believed to have arisen subsequently from combinations of prokaryotic cells, a concept known as the Endosymbiont Hypothesis.

They may be formed simply by being deep beneath the Earth's surface, subjected to high temperatures and the great pressure of the rock layers above it. They can form from tectonic processes such as continental collisions, which cause horizontal pressure, friction and distortion.

Corresponding, to this theory, planets what we call know were formed within the disk. Whereas, in protoplanet Hypothesis we get to know the present solar system and universe working. Though having many things in common with nebular hypothesis this hypothesis has modern implement of states of matter and fluid.

Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.

Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together.

The Short Answer: A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form.

Maybe you meant “Nebular hypothesis”. If yes, then the difference is that the former is about formation and evolution of planetary systems only; while the latter covers formation and evolution of the whole Universe. ... For Big bang theory on the other hand it is the planets that have lower priority.

None of the stars are on fire. They are just balls of gases and are not burning. They are not ignited. They are under thermonuclear fusion reactions.

For low-mass stars (left hand side), after the helium has fused into carbon, the core collapses again. As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. ... Like low-mass stars, high-mass stars are born in nebulae and evolve and live in the Main Sequence.
