- A star forms a nebula when it runs out of fuel. The star either  becomes a red giant or a supergiant, then the star would be blown  off into space either by expansion or exp…losion. The outer layers,  which was released into space, would become a nebula, or sometimes  a part of a larger nebula.

Stars' Life Cycle A ring-shaped nebula formed by an expanding shell of gas around an aging star. Death of a massive star. Stars that are over three times the mass of the sun have short life spans, which end in supernova events. The star's interior condenses and may produce a hot dense object that is either a neutron star or black hole.

What is a planetary nebula? A planetary nebula is created when a star blows off its outer layers after it has run out of fuel to burn.These outer layers of gas expand into space, forming a nebula which is often the shape of a ring or bubble.bout 200 years ago, William Herschel called these spherical clouds planetary nebulae because they were round like the planets. At the center of a planetary nebula, the glowing, left-over central part of the star from which it came can usually still be seen. 1  Javascript must be enabled to use Cool Cosmos.

- Mercury is one of the two inner planets between the Sun and the Earth. It is therefore considered as a very personal planet. It never strays very far from the Sun and indeed is not so easy to see because of it's proximity to the Sun.

A Planetary Nebula Sampler A Planetary Nebula Sampler. A planetary nebula forms when a star can no longer support itself by fusion reactions in its center. The gravity from the material in the outer part of the star takes its inevitable toll on the structure of the star, and forces the inner parts to condense and heat up. Planetary Nebula Sampler.

What is a nebula? how does it from a protostar? when does it become a star?? A nebula (Latin for cloud; pl. nebulae, nebulae, nebulæ or) nebulas is an interstellar cloud of, dust, hydrogen helium and other ionized. gasesxamples of these types of nebulae are the Rosette Nebula and the Pelican Nebula. The size of these nebulae, known as HII regions, varies depending on the size of the original cloud of gas. New stars are formed in the nebulae.

Ring Nebula Within the last two thousand years, the central star of the Ring Nebula has left the asymptotic giant branch after exhausting its supply of hydrogen fuel. Thus it no longer produces its energy through nuclear fusion and, in evolutionary terms, it is now becoming a compact white dwarf star.

How Does a Star Form? Stars begin as vast clouds of cold molecular hydrogen and helium left over from the Big Bang. These vast clouds can be hundreds of light years across and contain the raw material for thousands or even millions of times the mass of our Sun.

General Astronomy/Print version Protostar Herbig-Haro 34. Protostars are formed in star nurseries called nebulas, while nebulas are areas of higher dust and gas densities relative to the surrounding interstellar space. Nebulas are made up of mostly hydrogen and a little helium, although more massive elements and even molecules are also ubiquitous.

Nebula One of the best examples of this is the Crab Nebula, in Taurus. The supernova event was recorded in the year 1054 and is labelled SN 1054. The compact object that was created after the explosion lies in the center of the Crab Nebula and is a neutron star. Other nebulae may form as planetary nebulae.

A Star is Born A Star is Born Molecular clouds are perfect star-forming regions because the combination of these atoms into molecules is much more likely in very dense regions. This photograph shows the Orion Nebula, an interstellar cloud in which star systems - and possibly planets - are forming. Our own solar system presumably formed as gravity caused the collapse of a similar large cloud of gas. The piece of cloud that formed our Solar System is known as the solar nebula.

Star formation Star formation is the process by which dense regions within molecular clouds in interstellar space, sometimes referred to as stellar nurseries or star-forming regions, fuse to form stars.[1] As a branch of astronomy, star formation includes the study of the interstellar medium (ISM) and giant molecular clouds (GMC) as precursors to the star ...

Stellar evolution Later, as the preponderance of atoms at the core becomes helium, stars like the Sun begin to fuse hydrogen along a spherical shell surrounding the core. This process causes the star to gradually grow in size, passing through the subgiant stage until it reaches the red giant phase.

Why Do Stars Burn and What Happens When They Die? Another type of star, the neutron star, come into being when a star collapses and the neutron-to-neutron repulsion counteracts the gravitational collapse. However, not all stars become white dwarf stars or even neutron stars. Chandrasekhar realized that some stars would have very different fates.

The Crab Nebula (M1): Facts, Discovery & Images The guts of the nebula. A supernova remnant forms when the pressure inside of a star is stronger than the gravity that holds it together, and the star explodes. As the gas rushes outward, it fills the space around it. The material ejected from the Crab Nebula is moving at more than 3 million mph (4.8 million kph).

What event marks the birth of a star and what event marks its death? The birth of a star can typically occur due to the death of another star. There are huge dark clouds made of of gas and dust in space. These are called nebulas. When a nearby star explodes, a shockwave travels through the dark cloud. As the cloud collapses, energy is released, which causes it to heat up.

The Origin of the Solar System At about this time, about 1 million years after the nebula cooled, the star would generate a very strong solar wind, which would sweep away all of the gas left in the protoplanetary nebula. If a protoplanet was large enough, soon enough, its gravity would pull in the nebular gas, and it would become a gas giant. If not, it would remain a rocky or icy body. At this point, the solar system is composed only of solid, protoplanetary bodies and gas giants. The planetesimals would slowly collide with each other and become more massive. Eventually, after ten to a hundred million years, you end up with ten or so planets, in stable orbits, and that's a solar system.

Nebula Through supernova explosion: Some nebulae form by way of supernova explosions, caused by the collapse of massive, short-lived stars. The materials thrown off from the gigantic explosion are known as supernova remnants. Example: Crab Nebula. Through shedding off the outer layers of a low mass star: Other nebulae form as planetary nebulae. This is the final stage of a low-mass star's life, like our Sun. Such stars evolve into red giants and then blow off their outer layers of gas. These stars do not have enough mass to go supernova. Example: Ring Nebula.

Solar Nebular Hypothesis: Definition & Explanation Formation. It is believed that before our Solar System was formed 4.5 billion years ago, a nebula was present in our location. As gravity does with everything, it began to condense the gas into varying regions of density.

Stars Main Sequence Stars. A star the size of our Sun requires about 50 million years to mature from the beginning of the collapse to adulthood. Our Sun will stay in this mature phase (on the main sequence as shown in the Hertzsprung-Russell Diagram) for approximately 10 billion years.

Stellar Birth and Middle Age Eventually, a protostars central temperature becomes high enough for hydrogen fusion to begin, and the protostar becomes a star. For a star like the Sun, the whole formation process takes about 50 million years. The zero-age main sequence is the main-sequence band predicted by stellar evolutionary theory.

Star The formation of a star begins with gravitational instability within a molecular cloud, caused by regions of higher density-often triggered by shock-waves from nearby supernovae (massive stellar explosions), the collision of different molecular clouds, or the collision of galaxies (as in a starburst galaxy).

The Life Cycles of Stars: How Supernovae Are Formed If the remnant of the explosion is 1.4 to about 3 times as massive as our Sun, it will become a neutron star. The core of a massive star that has more than roughly 3 times the mass of our Sun after the explosion will do something quite different.he core remains as a white dwarf and eventually cools to become a black dwarf. On the right of the illustration is the life cycle of a massive star (10 times or more the size of our Sun). Like low-mass stars, high-mass stars are born in nebulae and evolve and live in the Main Sequence.
