New stars are very hot, so they look white or blue-white. Middle-aged stars are not as hot. They turn yellow like the sun and have temperatures of about 10,000 degrees Fahrenheit (5,538 degrees Celsius).
Stars get old after ten billion years and run out of fuel. They get hotter and larger. They become red giant stars. Some of these stars are 40 or 50 million miles (64 or 80 million kilometers) across.

A black hole is sort of like a very powerful vaccuum cleaner sucking in everything, and not letting anything escape. Black holes are invisible. Scientists have found a black hole in our galaxy the size of 3 million suns. Black holes are known to have gases spiral into them.Black holes are formed when huge stars die and explode. This explosion is called a supernova. If this star is big enough, a black will form after the supernova. Black holes are not even really holes, they are just called that because of what they look like. They are made up of many materials such as dust, gas, stars, and other space debris. Once something is pulled into a black hole it is never seen again. A black hole has such high gravity that objects are pulled at very high speeds toward it.

Very dense. Black holes are only 4 times bigger than the sun, but they are very powerful. Scientists figure out that there is a black hole by measuring mass in a region of the sky and look for areas of large, dark mass. Many black holes exist in the binary star systems. A black hole is called " black " because it absorbs all the light that hits the event horizon(point of no return), reflecting nothing. Black holes emit radiation.
In the 18th century, John Mitchell and Pierre Laplace considered that some objects may have such a strong gravity field that it is too strong for light to escape.

- A black hole only has three independant physical properties: mass, charge, and angular momentum.These are special because they are noticed visibly from the outside of the black hole.
- Black holes that have mass but no charge or angular momentum are called Schwarzchildin black holes.
- Black holes are classified according to their mass, so a supermassive black hole would have a mass of about 100,000 - 1,000,000,000.
- In 1970, Stephen Hawking defined the modern theory of black holes, which describes the fate of the black holes.

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 Giant:
This 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.

The Birth of a Star
In space, there exists huge clouds of gas and dust. These clouds consist of hydrogen and helium, and are the birthplaces of new stars. Gravity causes these clouds to shrink and become warmer. The body starts to collapse under its own gravity, and the temperature inside rises. After the temperature reaches several thousand degrees, the hydrogen molecules are ionized (electrons are stripped from them), and they become single protons. The contraction of the gas and the rise in temperature continue until the temperature of the star reaches about 10,000,000 degrees Celsius (18,000,000 degrees Fahrenheit). At this point, nuclear fusion occurs in a process called proton-proton reaction. Briefly, proton-proton reaction is when four protons join together and two are converted into neutrons; an 4He nucleus is formed. During this process, some matter is lost and converted to energy as dictated by Einstein's equation. At this point, the star stops collapsing because the outward force of heat balances the gravity.
A star is a really hot ball of gas, with hydrogen fusing into helium at its core. Stars spend the majority of their lives fusing hydrogen, and when the hydrogen fuel is gone, stars fuse helium into carbon. The more massive stars can fuse carbon into even heavier elements, which is where most of the heavy elements in the universe are made. Throughout this whole process is that battle between gravity and gas pressure, known as equilibrium. It’s crucial to keep this battle in your mind when trying to understand how stars live and die.
A star's life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star's mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born. Over time, the hydrogen gas in the nebula is pulled together bygravity and it begins to spin. As the gas spins faster, it heats up and becomes as a protostar. Eventually the temperature reaches 15,000,000 degrees and nuclear fusion occurs in the cloud's core. The cloud begins to glow brightly, contracts a little, and becomes stable. It is now a main sequence star and will remain in this stage, shining for millions to billions of years to come. This is the stage our Sun is at right now.
