SOme cool stuff in the issue:

SUnrise view of MArs

The sharp edges of the channels suggest that they are no more than a few million years old. NASA scientists say that the braided gullies look as if sediment-rich streams had carved them, supporting the notion that water once flowed across much of the Red Planet.

"This shows a soaking-wet Mars," says Alfred McEwen of the University of Arizona in Tucson. The orange areas, enhanced for greater contrast, show clay-rich soil, which the scientists say could have formed only in the presence of water. The lightest areas in the picture are covered in carbon dioxide frost, which will burn off during the Martian day.

NEIGHBORHOOD VIOLENCE. A newfound dust ring (inside white box) at the core of the Andromeda galaxy and the previously known outer dust ring suggest that the small galaxy M32 (arrow) barreled through Andromeda 210 million years ago.


And in a galaxy far, far away a long time ago...

SO FAR AWAY. The most remote galaxy known (red) lies 12.88 billion light-years from Earth. Image depicts radiation emitted by hydrogen atoms.


Look just like I thought it would.

Not to mention a nice article about the "new" rings around Saturn

NEW VIEW. This panoramic portrait combines 165 images taken on Sept. 15, when Cassini was behind Saturn, which sheltered the craft from the sun's blinding glare, thereby permitting a unique view.

I think that is the best image of Saturn I have ever seen.
