L1527 and Protostar

An hourglass-shaped, multi-color cloud set against the black, starry background of space. This cloud of dust and gas is illuminated by light from a protostar, a star in the earliest stages of formation. The upper “bulb” of the hourglass is orange, while the lower “bulb” transitions from white to dark blue. Together, the two bulbs stretch out like butterfly wings turned 90 degrees to the side. Extending from the upper and lower bulbs are long, wispy filaments of color, looking almost like burning fire. In the center of the hourglass shape is a small, dark demarcation line. This line is an edge-on view of a protoplanetary disk, a disk of material being pulled into a star as it forms.
