Disc Of Dusty Material Leftover From Star Forming Clock

In this artist's impression, a disc of dusty material leftover from star formation girds two young stars like a hula hoop. As the two stars whirl around each other, they periodically peek out from the disc, making the system appear to blink every 93 days. The dusty hula hoop itself is misaligned from the central star pair, thanks to the disrupting gravitational presence of a third star orbiting at the periphery of the system. The light yellow arcs near the two central stars indicate their movement relative to each other and the disc. It is believed that this disc will go on to spawn planets and the other celestial bodies that make up a solar system. Spitzer Space Telescope observed this system, called YLW 16A, in the infrared light emitted by the disc's warmed gas and dust.
