Mary Travers of Peter, Paul and Mary dies

The band’s publicist, Heather Lylis, says Travers died at Danbury Hospital in Connecticut on Wednesday. She was 72 and had battled leukemia for several years.
Travers joined forces with Peter Yarrow and Noel Paul Stookey in the early 1960s.
And they were vehement in their opposition to the Vietnam War, managing to stay true to their liberal beliefs while creating music that resonated in the American mainstream.
At one point in 1963, three of their albums were in the top six Billboard best-selling LPs as they became the biggest stars of the folk revival movement.
But the trio continued their success, scoring with the tongue-in-cheek single “I Dig Rock and Roll Music,” a gentle parody of the Mamas and the Papas, in 1967 and the John Denver-penned “Leaving on a Jet Plane” two years later.

N = N* fp ne
fl fi fc
fL

N* represents the number of stars in the
Milky Way Galaxy
fp is the fraction of stars that have planets
around them
ne is the number of planets per star that
are capable of sustaining life
fl is the fraction of planets in ne
where life evolves
fi is the fraction of fl
where intelligent life evolves
fc is the fraction of fi
that communicate
fL is fraction of the planet's life during
which the communicating civilizations live
N, the number of communicating civilizations
in the galaxy.

Try your hand at the Drake Equation. For each variable choose what you
think is the best answer from the combo box. After you've chosen all your
answers press the calculate button and see how many communicating civilizations

Saturn's Nightside

clipped from www.redorbit.com

In the Shadow of Saturn

In the shadow of Saturn, unexpected wonders appear. The robotic Cassini spacecraft now orbiting Saturn recently drifted in giant planet's shadow for about 12 hours and looked back toward the eclipsed Sun. Cassini saw a view unlike any other. First, the night side of Saturn is seen to be partly lit by light reflected from its own majestic ring system. Next, the rings themselves appear dark when silhouetted against Saturn, but quite bright when viewed away from Saturn and slightly scattering sunlight, in the above exaggerated color image. Saturn's rings light up so much that new rings were discovered, although they are hard to see in the above image. Visible in spectacular detail, however, is Saturn's E ring, the ring created by the newly discovered ice-fountains of the moon Enceladus, and the outermost ring visible above. Far in the distance, visible on the image left just above the bright main rings, is the almost ignorable pale blue dot of Earth.
