The overall dimming of starlight passing through dust clouds is Extinction .
To find the answer, we need to know more about the Extinction.
What is Extinction ?
- Extinction is the electromagnetic radiation that is absorbed and scattered by gas and dust between an emitting astronomical object and the observer.
- Robert Julius Trumpler first identified interstellar extinction around 1930.
- However, Friedrich Georg Wilhelm von Struve had identified its effects in 1847, and a number of people had seen its impact on star colors but had not made the connection between it and the general abundance of galactic dust.
- Extinction in the visual band of frequencies (photometric system) for stars in the Milky Way plane and within a few thousand parsecs of the Earth is approximately 1.8 magnitudes per kiloparsec.
Thus, we can conclude that, the overall dimming of starlight passing through dust clouds is Extinction .
