Nebulas

Nebulas. By Blaine Vrvilo. Description. Nebulas are clouds of dust and gasses that form between stars. They form in regions where gas, dust, and other materials clump together to create larger masses, which then gather other material until they become big enough to be known as stars.

  1. Nebulas By Blaine Vrvilo

  2. Description Nebulas are clouds of dust and gasses that form between stars. They form in regions where gas, dust, and other materials clump together to create larger masses, which then gather other material until they become big enough to be known as stars.

  3. Emission Nebulae Emission nebulae emit red or pink light. The light is actually extra energy being emitted in the form of light.

  4. Reflection Nebulae Reflection nebulae shine with a blue light, which is reflected from stars around it. They are blue because, they scatter the blue  light from nearby stars while the rest of the colors are allowed to pass through the cloud.

  5. Planetary Nebulae A planetary nebulae is formed when a sun sized star begins to die, and sheds its outer layers. These nebulas are only visible for around 50,000 years, until they eventually mix into outer space and become to thin to see.

  6. Bok Globule Bok globules are extremely dense and actually block all of the light behind them.

  7. Geology Nebulas form stars which supplies energy to planets providing the possibility of life.
