The article describes the study of cosmic dust grains from the earth's closest star named AU Microscopii. This 12-million year old star was discovered by astronomy professor Paul Kalas. James Graham, another professor of astronomy, states that dust grains from the debris around the stars mix with ice particles to form a dirty snowball. Scientists have found that star particles differ in formation and density, which alters their texture.

    We discuss the dust attenuation and the star formation rates in the nearby universe obtained from a comparison of far-infrared (IRAS) and ultraviolet (GALEX) observations. The ratio of the dust to UV flux ratio is used to derive the dust attenuation: this dust attenuation is found to increase...
