Also, the interstellar cloud is a filled space between the other stars, that has a rattling low density (Interstellar Medium). A star forms from a interstellar cloud by combining with other atoms. With the temperature being, nothing to just above zero degrees, the atoms of the gas' start to sick together. Then the star forms in a molecular cloud. A molecular cloud, is just a thick compact of interstellar gas and dust.
( Millis 2014) It is believed that super massive black holes exist in the cores of many large galaxies, including the Milky Way galaxy, which is our galaxy. (Swinburne University 2014). It is believed that a normal black holes were formed because of a supernova explosion of a gigantic star, meaning when huge stars collapse, so the larger the star, the larger the black hole. ( Millis 2014) . So therefore a simple idea of how a super massive black hole might have been formed would be because of a collision of super enormous star or a collision of star clusters (star clouds).

Another type of nebulae is the planetary nebulae, which occurs near the end of a star’s lifetime. Although planetary nebular have “planet” in their name, the only thing they have to do with planets is looking similar to them. These nebulae occur when an average size star runs out of fuel and dispels its gas into rings of colorful light. Another type of nebulae, called dark nebulae, are interstellar clouds with dust so com... ... middle of paper ... ... low-mass or high-mass protostar forms. The low mass-protostar then goes on to form your average star, just like our Sun.
