The Nebula

Outer space when viewed from far away look so calm. But, did you know, turns out to be beyond space always happens blasts often called nebula by astronomers.

The Nebula is the mother of stars in space. The stars are old (age range 30-billion years old) are going to die. The demise of these old star ends with the star of the hit. The explosion of the star-shaped smoke and gas, dust and containing also the plasma. This explosion called a planetary nebula. The content of the gas, dust and plasma will also mutually binding and large clots cause. Tufts is also interesting objects that are in the vicinity. The molecules that exist inside each stack and solidified and with the help of a star. Nebula can give birth to thousands of stars in the all explosions.

One of the famous nebula that became the birthplace of many stars is a vague spot in the constellation Orion, known as the Orion Nebula. Seen from the outside, a nebula appears dark and gloomy, but on the inside they look with the brightest new stars were born. From a distance the nebula looks so lovely and so unique in outer space.

The Stars

One of the most beautiful objects in the sky are stars. The star is the space objects emit light. the star is also one of the object outer space that can be seen from the Earth at night without use a telescope, but its size is small. The size of the actual star is very great when we see it using telescopes. However, there are also the stars we can see with the naked eye with the relative sizes of, namely the Sun, big star closest to our Earth.

The stars also has a light color that symbolizes the temperature and also to determine if there is a planet circling the star or not. Glowing stars shining  red or low temperatures, usually cause the star was unable to collect the dust and gas around it for the planet, so it is often called a lonely star. Stars shining yellow or glowing are usually have a planet around it, because it was able to attract the dust and gas around it for the planet. Then, Stars shining blue or bright stars (often called Papuan morning star) temperatures tend to be high, causing gas and dust around it to avoid, so it tends not to have planets, and often called lonely stars like the red stars.

The star has also the age. Aged stars were determined based on the severity. Average age of stars ranging from 30 billion years – 40 billion years.

Meaning and History of Celestial Objects Outer Space

Before discussing one by one on space objects, it would be better if we knew ahead of time about understanding and historical discovery. Because by knowing that we will be able to find lots of space objects which was amazing.

The sky is the upper part of the Earth's surface, and is classed as a separate layer called the atmosphere. The sky consists of a lot of gas and air, with different compositions in each lapisannya. Sky blue is often seen, due to the light, but not Ricochet covered the possibility that sky could also, for example, colored red when the twilight, or black as rain.

Space Objects are all objects that are in the Arch of heaven, well in sight during the day or at night. During the day, we look at the Sun, while in the evening, we see the Moon, the stars, and so forth.

The closest celestial is days. The distance to the Earth "only" about 384.000 kilometers. The Moon is a satellite of the Earth, always loyal and surrounds follow wherever the earth moving. The Moon shined as it reflects light from the Sun.

The history of the discovery of the heavenly bodies had anything to do with the formation of the solar system, especially the heavenly bodies that exist in our solar system. There are several hypotheses that State the origin of the solar system which has been expressed by some experts, that is, the Big Bang Hypothesis, Hypotheses, Tidal Planetesimal Hypothesis, Hypotheses condensation, Star and Twin Star Hypothesis. However most believe is yaang Hypothesis of the Big Bang.

The history of the discovery of the solar system at the start with planets seen with the naked eye. Development of science and technology observations on five centuries ago carrying humans to understand heavenly bodies free from mythology, until it finds a tool to observe the sky objects more clearly the Telescope from Galileo. The development of the telescope is balanced with the development of the calculation of the heavenly bodies and their relationship to each other.
