This is one reason why astronomers work in wavelengths OTHER than visible light.

One blink image is a colorful pillar of gas and dust photographed by Hubble’s visible channel of the Wide Field Camera 3 (WFC3). In the other blink, we are looking at the same pillar, only this image is in the infrared.The structure we see is a three-light-year-long cloud of dense material, shaped by its interaction with radiation from stars both within and without.

The cloud is opaque in visible wavelengths, but when we look at the same region in the infrared, the cloud becomes a transparent, ghostlike feature, and four bright newborn stars are now visible. One of the stars has two jets blasting from its poles. Such activity is observed only in stars under 100,000 years old.

note: there is a poster available of these two images side by side.
