This photo shows the cosmic region known as Sh2-239 and LDN 155, where star formation activity has caused the mix of dust and colors in the nebulas visible here. The deep colors and dark clouds in this image resemble paintings by some of history’s greatest artists.
The region lies near the southern end of Taurus located on the border of the constellations of Taurus and Perseus more than 400 light-years away. A light-year is the distance light travels in one year, or about 6 trillion miles (10 trillion kilometers).
Astrophotographer Adam Block of the Mt. Lemmon SkyCenter at the University of Arizona was one of the first to capture the nebula in such detail. He took multiple exposures to collect enough light for an image that would otherwise not be evident to the eye.
