Telstra has revealed the addition of almost one million new mobile services in the six months to December 2011, but Sensis revenues plummeted 24 percent in 12 months.
NASA states, “The ring itself is tenuous, made up of a thin array of ice and dust particles. Spitzer's infrared eyes were able to spot the glow of the band's cool dust.”
Dr. Verbiscer said, "The particles are so far apart that if you were to stand in the ring, you wouldn't even know it." [NASA]
Spitzer observed the glow of the cool dust, which has a temperature of only about 80 Kelvin (minus 316 degrees Fahrenheit).
Dr. Verbiscer said, "By focusing on the glow of the ring's cool dust, Spitzer made it easy to find."
Because the ring is thought to have formed from micrometeroid impacts to the moon Phoebe, astronomers think that the ring orbits in a retrograde orbit, like Phoebe.
In addition, these astronomers who made the discovery believe that materials within this ring may have affected the moon Iapetus, making its leading hemisphere (in its orbit) different in appearance from its trailing hemisphere.
Its leading face looks dark with a reddish-brown coloring, while its trailing face is bright. The NASA article states, some of “… the dark and dusty material from the outer ring moves inward toward Iapetus, slamming the icy moon like bugs on a windshield.”
