This image shows the Eagle Nebula’s Pillars of Creation as seen in visible light, capturing the multi-colored glow of gas clouds, wispy tendrils of dark cosmic dust, and the rust-colored elephants’ trunks of the nebula’s famous pillars. The dust and gas in the pillars is seared by the intense radiation from young stars and eroded by strong winds from massive nearby stars. Image credit: NASA / ESA / Hubble / Hubble Heritage Team.
