discovered around Saturn.
I also want to remind you about our big annual meeting next

Book of the Month
NightWatch: A Practical Guide to Viewing the Universe
Dickinson, Adolf Schaller, Victor Costanzo and Roberta
The first 3 editions of NightWatch sold more than
600,000 copies, making it the top-selling stargazing
guide in the world for the last 20 years. The key
feature of this classic title is the section of star
charts that are cherished by backyard astronomers
everywhere. NightWatch has been acclaimed as the best
general interest introduction to astronomy.
Discovered Around Saturn
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.

Ares I-X Was
Last Tuesday the Aries I-X vehicle was launched from Kennedy
Space Center (LC-39) in Florida, successfully completing a brief
test flight. The vehicle's first stage ignited at T-0 seconds
and Ares I-X lifted off from Launch Complex 39. The first stage
separated from the upper stage
and parachuted into the Atlantic Ocean roughly 150 miles (240
km) downrange of the launch site. The maximum altitude of the
rocket was not immediately known, but had been expected to be 28
miles (45 km).
The launch accomplished all primary test objectives, and many
lessons were learned in preparing and launching a new vehicle
from Kennedy Space Center.
