A. Dust bunnies form from the surprisingly large supply of stuff in the air, including fibers from clothing fabrics and carpeting; hair; animal fur and dander; and especially human skin cells and the dust mites that feed on them, according to Joseph Laquatra Jr., professor of design and environmental analysis at the College of Human Ecology at Cornell.
Current Understanding. A cloud collapses to form a star and disk. Planets form from this disk. According to our current understanding, a star and its planets form out of a collapsing cloud of dust and gas within a larger cloud called a nebula.As gravity pulls material in the collapsing cloud closer together, the center of the cloud gets more and more compressed and, in turn, gets hotter.hese circumstellar or protoplanetary disks, as astronomers call them, are the birthplaces of planets. Small clumps of material within a disk stick together to form larger clumps. Eventually these clumps grow to become planets. As a disk spins, the material within it travels around the star in the same direction.
