THE LIFE CYCLE OF A STAR

Outlined below are the many steps involved in a stars evolution, from its formation in a nebula, to its death as a white dwarf or neutron star.

The Process of Cycle:
"They well be changed like clotches from one cycle to another cycle after experation of cycle

"You will roll them up like a robe, and they will be changed like clothes. But you remain the same, and your life will never end."(Hebrew 1:12)

The earth shall quake before them; the heavens shall tremble: the sun and the moon shall be dark, and the stars shall withdraw their shining:

NEBULAA nebula is a cloud of gas (hydrogen) and dust in space. Nebulae are the birthplaces of stars. There are different types of nebula. An Emission Nebula e.g. such as Orion nebula, glows brightly because the gas in it is energised by the stars that have already formed within it. In a Reflection Nebula, starlight reflects on the grains of dust in a nebula. The nebula surrounding the Pleiades Cluster is typical of a reflection nebula. Dark Nebula also exist. These are dense clouds of molecular hydrogen which partially or completely absorb the light from stars behind them e.g. the Horsehead Nebula in Orion.
Planetary Nebula are the outer layers of a star that are lost when the star changes from a red giant to a white dwarf.

Which commandeth the sun, and it riseth not; and sealeth up the stars. (Job 9:7)
STARA star is a luminous globe of gas producing its own heat and light by nuclear reactions (nuclear fusion). They are born from nebulae and consist mostly of hydrogen and helium gas. Surface temperatures range from 2000�C to above 30,000�C, and the corresponding colours from red to blue-white. The brightest stars have masses 100 times that of the Sun and emit as much light as millions of Suns. They live for less than a million years before exploding as supernovae. The faintest stars are the red dwarfs, less than one-thousandth the brightness of the Sun.
The smallest mass possible for a star is about 8% that of the Sun (80 times the mass of the planet Jupiter), otherwise nuclear reactions do not take place. Objects with less than critical mass shine only dimly and are termed brown dwarfs or a large planet. Towards the end of its life, a star like the Sun swells up into a red giant, before losing its outer layers as a Planetary Nebula and finally shrinking to become a white dwarf.

RED GIANTThis is a large bright star with a cool surface. It is formed during the later stages of the evolution of a star like the Sun, as it runs out of hydrogen fuel at its centre. Red giants have diameter's between 10 and 100 times that of the Sun. They are very bright because they are so large, although their surface temperature is lower than that of the Sun, about 2000-3000�C.
Very large stars (red giants) are often called Super Giants. These stars have diameters up to 1000 times that of the Sun and have luminosities often 1,000,000 times greater than the Sun.

RED DWARFThese are very cool, faint and small stars, approximately one tenth the mass and diameter of the Sun. They burn very slowly and have estimated lifetimes of 100 billion years. Proxima Centauri and Barnard's Star are red dwarfs.

WHITE DWARFThis is very small, hot star, the last stage in the life cycle of a star like the Sun. White dwarfs have a mass similar to that of the Sun, but only 1% of the Sun's diameter; approximately the diameter of the Earth. The surface temperature of a white dwarf is 8000�C or more, but being smaller than the Sun their overall luminosity's are 1% of the Sun or less.
White dwarfs are the shrunken remains of normal stars, whose nuclear energy supplies have been used up. White dwarf consist of degenerate matter with a very high density due to gravitational effects, i.e. one spoonful has a mass of several tonnes. White dwarfs cool and fade over several billion years.

SUPERNOVAThis is the explosive death of a star, and often results in the star obtaining the brightness of 100 million suns for a short time. There are two general types of Supernova:-
Type I These occur in binary star systems in which gas from one star falls on to a white dwarf, causing it to explode."When The  "Sun" explode this the time that the sun is darkened.(Acts 2:20,Ecle.12:2) the Death of Sun

Type II These occur in stars ten times or more as massive as the Sun, which suffer runaway internal nuclear reactions at the ends of their lives, leading to an explosion. They leave behind neutron stars and black holes.Supernovae are thought to be main source of elements heavier than hydrogen and helium.

NEUTRON STARSThese stars are composed mainly of neutrons and are produced when a supernova explodes, forcing the protons and electrons to combine to produce a neutron star. Neutron stars are very dense. Typical stars having a mass of three times the Sun but a diameter of only 20 km. If its mass is any greater, its gravity will be so strong that it will shrink further to become a black hole. Pulsars are believed to be neutron stars that are spinning very rapidly.

BLACK HOLESBlack holes are believed to form from massive stars at the end of their life times. The gravitational pull in a black hole is so great that nothing can escape from it, not even light. The density of matter in a black hole cannot be measured. Black holes distort the space around them, and can often suck neighbouring matter into them including stars.

  White dwarfs are the still-burning carbon and helium cores of exploded red giants. They often accompany a planetary nebula, which is composed of the remnants of the exploded giant's outer surfaces. Ironically, planetary nebulae do not contain planets, nor do they produce them. They got their name thanks to the confusion of early astronomers. These astronomers were correct in their assumptions that the nebulae they were observing were of similar size to our solar system, but they were fooled by fuzzy areas of the nebulae that resembled planets. This remnant is referred to as a white dwarf and will only burn for five to ten thousand years. The nebula is only visible for a few tens of thousands of years. Most stars, our sun included, will come to this end.

Stars are a fascinating component of our universe. They may seem like permanent objects in the sky, but technology has allowed us to photograph the heavens, and now we know more about stars than ever before. They are born, they live, and then they die. How does this happen?

That’s what this activity is all about! A star’s life is long compared to that of a human, but we can see the stages of stellar birth, aging, and death in the heavens. They follow a pattern similar to many of the life cycles we see here on earth. Stars are born, they “grow up,” exist many years, and then they die, and there’s an exciting battle between the force of gravity and gas pressure to that makes it exciting and potentially explosive!

Space: What’s out there?

Space may seem empty, but actually it is filled with thinly spread gas and dust. This gas and dust is called interstellar medium. The atoms of gas are mostly hydrogen (H₂), and the gas atoms are typically about a centimeter apart. The dust is mostly microscopic grains and comprises only a few percent of the matter between stars. The dust is mostly carbon and silicon. In some places, this interstellar medium is collected into a big cloud of dust and gas known as a nebula. This is the birthplace of stars because the gas and dust is what makes up a star. In fact, our sun was probably born in a nebula nearly 5 billion years ago.
