source: Reflection nebulae are commonly blue because the scattering is more powerful for blue light than red (this is the same reason for the sky appears in blue and the sunset in red colors
target: Reflection nebulae are usually blue because the scattering is more efficient for blue light than red (this is similar scattering process that gives us blue skies and red sunsets).
references: Reflection nebulae are usually blue because the scattering is more efficient for blue light than red (this is similar scattering process that gives us blue skies and red sunsets). Because the scattering process that gives us blue skies and red sunsets works better for blue light, reflection nebulae are more often blue. Reflection nebulae are usually blue because the scattering is more efficient for blue light than red . This same process gives us blue skies and red sunsets. Reflection nebulae are blue because the scattering is more efficient for blue light than red. Reflection nebulae (a cloud of gas and dust in outer space) are usually blue because the random spreading in various directions is more capable for blue light than red (this is the same spreading process that gives us blue skies and red sunsets). Reflection nebulae are usually blue because the scattering is more efficient for blue light than red (the same scattering process that gives us blue skies and red sunsets).
