The life cycle of the sun

Although the Sun isn't something you typically think of as living, the Sun, like other living things, has a life cycle. In fact, the heat of the interior is so great, that a layer of Hydrogen gas around the Helium-fusing core begins to fuse into Helium, generating even more outward pressure.

Eventually, the Red Giant Sun will lose its outer envelope, leaving behind a tiny ball of tightly squeezed Carbon.

Life cycle of a massive star

This will cause the core to heat up and get denser, causing the Sun to grow in size and enter the Red Giant phase of its evolution. Each layer would take less time than the last, all the way up to nickel — which could take just a day to burn through. The proportions of metals heavier elements is unchanged. Over the past 4. However, the mass is insufficient to generate the high temperatures necessary to fuse Carbon into something else. Eventually, the material in the center of the cloud mass was squeezed so strongly by gravity that pressures exceeded billions of atmospheres and temperatures soared up to 7 million K. Although the Sun isn't something you typically think of as living, the Sun, like other living things, has a life cycle.

Because the Sun is a gaseous object, it does not have a clearly-defined surface; its visible parts are usually divided into a 'photosphere' and 'atmosphere'. This is the moment we consider the Sun to have been born.

The life cycle of the sun

The Center of Our Solar System The Sun is the biggest and most important star in our solar system - without it, there would be no life on Earth. The sheer energy of the fusion is making every effort to literally blow up the Sun. Each layer would take less time than the last, all the way up to nickel — which could take just a day to burn through.

Red giant life cycle

No one on Earth can life long enough to watch the entire lifecycle of our Sun, so we turn to the stars in space to see those of similar mass and at different stages of their lifecycle to make a theoretical picture of what our Sun's life may have been like and will be. Once the dust clears, the only thing remaining will be a very dense star known as a neutron star , these can often be rapidly spinning and are known as pulsars. Unusual properties of Physics govern the form of material in a stellar core, and we will look into those unusual properties later. In the meantime, we have plenty of days of sunshine to look forward to! This lifespan began roughly 4. It looks so tame up there in the sky, but it is anything but tame. The Sun has always been the center of our cosmological systems. The gas of the Sun is blown outward, and the Sun grows larger and larger. As always, God or the Devil, depending on who you ask is in the details!

It is composed of four distinct parts: the chromospherethe transition regionthe corona and the heliosphere. The Sun has become a "Red Giant.

The two methods generally agree well.

Radiative zone — Convection cannot occur until much nearer the surface of the Sun. Core Hydrogen Exhaustion: All things must end.

The remaining Hydrogen nuclei will reach high levels of kinetic energy and collide successfully more frequently.

This will trigger a moist greenhouse effect here on Earth that is similar to the runaway warming that turned Venus into the hellish environment we see there today.
