NASA CASSINI IMAGES MAY REVEAL NEW SATURN MOON
THE WORLD AROUND USMountain Views-News Saturday, April 19, 2014 B2
NASA’s Cassini spacecraft has documented the formation of a small icy object within the
rings of Saturn that may be a new moon, and may also provide clues to the formation of the
planet’s known moons.
Images taken with Cassini’s narrow angle camera on April 15, 2013, show disturbances at
the very edge of Saturn’s A ring—the outermost of the planet’s large, bright rings. One of these
disturbances is an arc about 20 percent brighter than its surroundings, 750 miles long and 6
miles wide. Scientists also found unusual protuberances in the usually smooth profile at the
ring’s edge. Scientists believe the arc and protuberances are caused by the gravitational effects
of a nearby object. Details of the observations were published online today by the journal
Icarus [http://dx.doi.org/10.1016/j.icarus.2014.03.024].
The object is not expected to grow any larger, and may even be falling apart. But the process
of its formation and outward movement aids in our understanding of how Saturn’s icy moons,
including the cloud-wrapped Titan and ocean-holding Enceladus, may have formed in more
massive rings long ago. It also provides insight into how Earth and other planets in our solar
system may have formed and migrated away from our star, the Sun.
“We have not seen anything like this before,” said Carl Murray of Queen Mary University
of London, the report’s lead author. “We may be looking at the act of birth, where this object
is just leaving the rings and heading off to be a moon in its own right.”
The object, informally named Peggy, is too small to see in images so far. Scientists estimate
it is probably no more than about a half mile in diameter. Saturn’s icy moons range in size
depending on their proximity to the planet—the farther from the planet, the larger. And many
of Saturn’s moons are comprised primarily of ice, as are the particles that form Saturn’s rings.
Based on these facts, and other indicators, researchers recently proposed that the icy moons
formed from ring particles and then moved outward, away from the planet, merging with
other moons on the way.
“Witnessing the possible birth of a tiny moon is an exciting, unexpected event,” said Cassini
Project Scientist Linda Spilker, of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif.
According to Spilker, Cassini’s orbit will move closer to the outer edge of the A ring in late
2016 and provide an opportunity to study Peggy in more detail and perhaps even image it.
WRITE A LUNAR ECLIPSE POEM AND WIN A PRIZE!
Were you excited to see the lunar eclipse on the night of April 14-15? Enough to write a
poem about it? Why not try one, and email it to the Astronomers Without Borders (AWB)
AstroPoetry Contest? This international astronomy-outreach organization is presenting the
contest as a feature of Global Astronomy Month, April 2014.
The contest has separate divisions for children grades 1-6, young adults grades 7-12, and
adults. For contest rules and the entry form, see: http://astronomerswithoutborders.org/

UNHURT BY SHADOW
How bright the full moon
Coming out of her eclipse
Unhurt by shadow.
This image is a portion of an observation recorded by the narrow-angle camera of Cassini's imaging
science subsystem on April 15, 2013. The bright feature at the edge of the A ring is about 750 miles
(about 1,200 kilometers) long.

I have many fond
memories of 17 years
with my purebred pit
bull, Cassius Clay,
who died one Easter
Sunday. I remember
the end of his life the most right now. I thought
that I was taking care of Cassie and helping and
saving him – I had to carry him in and out, and
was always concerned about his welfare. In the
end, I realize that Cassie was helping and saving
me. He instilled in me a sense of responsibility
and caring that maybe I never had before.
When I walked today, I missed Cassie so much,
and I thought about his role in my life. I thought
about how I tried to see his dog pictures of the
world, how he processes the many smells that
he takes so long each day to smell. When I
attempted to go into his mind, like Beatrice
Lydecker described in her What the Animals
Tell Me book, I “saw” a colorful, very dynamic
image of flowing geometric shapes that all
moved like the wind in varying patterns, in a
three-dimensional complexity. To me, it was
the complexity of odors that meant so much to
Cassie, and very little to me.
Shortly after he died, I asked him to show me
his picture, and I “saw” in front of my his bigface licking mine. He was telling me that he was
happy, in peace, no pain and that I was OK.
As I walked this morning, I thought about
Easter Day when Cassie died. Though he had
had trouble walking for weeks, he seemed OK
in the morning. When I came home in the early

evening, it was dark and Cassie was warm but I
could not rouse him from his house, and when I
pulled him out, I knew it was over, even though
I tried to bring him back. There was no music,
no singing of birds, just the quiet of the night
and the final sounds of his dying body.
As I walked this morning, I realized that Cassie’s
gift was his unconditional love. And now that
he was gone, I tried to sort out the meaning of
that love. I have heard it said that Eternal Life
is synonymous with Eternal Love. That Eternal
Love is also impersonal. It is universal loving
without concern for prejudice or opinion or
preferences. It is doing what is right, and not
being concerned about my group, or my party,
or my race, or my gender, or my family. It is
finding those ways of thinking, and of living,
that exemplify the Golden Rule, and Jesus’
command to “Love ye one another as your self.”
Which means we must love our spiritual self,
and see that every single one of us is the same.
Cassie taught me to be a better person. He taught
me to see that only through impersonal love
can we ever find real meaning and harmony.
Of course, I feel a personal love for Cassie,
and for other close people in my life. But now
again, Cassie has made me realize that death is
inevitable, and personal love is full of pain and
heartache and disappointment. Impersonal
loving is not focused exclusively towards one
person or animal but is a way of thinking about
all life, including all animals. This was Cassie’s
gift to me.
