Trifids!
Dust pillars are like interstellar mountains. They survive because they are more dense than their surroundings; however, they are being slowly eroded by a hostile environment. Visible in the image above is the end of a huge gas and dust pillar in the Trifid Nebula, punctuated by a smaller pillar pointing up and an unusual jet pointing to the left.
