Giant Ring Discovered Around Saturn
Just when you thought every big thing in the Solar System had already been discovered, NASA’s Spitzer Space Telescope has found an extraordinary new ring around Saturn.
October 7, 2009: NASA’s Spitzer Space Telescope has discovered an enormous and previously unknown infrared ring around Saturn.
“This is one supersized ring,” says Anne Verbiscer, an astronomer at the University of Virginia, Charlottesville. “If you could see the ring in the night sky, it would span the width of two full Moons.”
The new belt lies at the far reaches of the Saturnian system, with an orbit tilted 27 degrees from the main ring plane. The bulk of its material starts about six million kilometers (3.7 million miles) away from the planet and extends outward roughly another 12 million kilometers (7.4 million miles). It would take about one billion Earths stacked together to fill the voluminous ring. One of Saturn’s farthest moons, Phoebe, circles within the newfound ring, and is likely the source of its material.
