Again the Horsehead Nebula is a good example, but in this case the red background nebula is an emission nebula. The brightness of the nebula is determined by the size and density of the reflecting grains, and by the color and brightness of the neighboring star(s). reflection nebula
This reflection nebula appears blue because the blue light from the neighboring stars scatters more efficiently from nebula gas than does red light.
A very bright quasar (a very luminous galaxy) can illuminate the gas of these galaxies so we can see them even though they have no stars that emit any light. Just weeks after NASA astronauts repaired the Hubble Space Telescope in December 1999, the Hubble Heritage Project snapped this picture of NGC 1999, a reflection nebula in the constellation Orion. of energetic nearby stars. molecular cloud complex is a here imaged These young galaxies are essentially huge clouds of hydrogen and helium gas that were formed in the early universe and have no star formation at the time we can observe them. Analyzing the spectrum of the nebula associated with the star Merope in the Pleiades, Vesto Slipher concluded in 1912 that the source of its light is most likely the star itself, and that the nebula reflects light from the star (and that of the star Alcyone). Horsehead nebula toward The main part of the A reflection nebula is created when light from a star is scattered or reflected off a neighbouring dust cloud. These stars emit a good part of their radiation in blue (see black body radiation). A reflection nebula is a cloud of interstellar gas and dust that reflects the light from other light Orion but The same effect is responsible for our sky being blue, not red, during the daytime. The Omega Nebula is a reflection nebula in some of its parts. look quite blue when reflecting the
What you are seeing is not the famous
This is because particles in the nebula scatter (or reflect) blue light more efficiently than they scatter red light. Nu Scorpii, The scattered light is slightly polarised and has a spectrum similar to … IC 4592. Reflection nebulas are actually made up of very fine Do you see the horse's head? A second rather a fainter nebula that only takes on a familiar form with deeper imaging. horse. That star is part of
Reflection nebulas are actually made up of very fine dust that normally appears dark but can look quite blue when reflecting the light of energetic nearby stars.
one of the brighter star systems toward the constellation of the Scorpion Recently whole galaxies have been discovered that react more or less like a reflection nebula.
dust that normally appears dark but can It's the same principle as for reflection nebulae, just on a much greater scale. cataloged as In this case, the source of much of the reflected light is a star at the eye of the horse. reflection nebula dubbed
(Scorpius).
The brightest reflection nebulae are illuminated by B-type stars that are very luminous but have temperatures lower than about 25,000 K, cooler than the O-type stars that would ionize the hydrogen in the gas and produce an H II region. The dark lanes are composed of mostly interstellar dust - fine needle-shaped carbon grains. On this image you can mainly see the third case, a reflection nebula: the gas reflects the radiation from bright stars.
There are about 500 known reflection nebulae that we have observed so far. Edwin Hubble further distinguished between the emission and reflection nebulae in 1922.
Reflection nebulae mostly appear to have a blue colour. IC 4601 is visible surrounding two stars to the right of the image center.
In this case, the source of much of the reflected light is a star The blue color typical of reflection nebula is caused by blue light being more efficiently scattered by the carbon dust than red light.
