Decoding the colours of NGC 3344 (12x2)

:

Our eyes detect only visible light, but on board Hubble are a variety of instruments that together detect many different wavelengths of light. This means that Hubble is able to observe galaxies over a wide range of wavelengths to reveal features that would otherwise remain invisible to our eyes. This episode of the Hubblecast explores the meaning of the colours in the spiral galaxy NGC 3344.
