Saturn's Ancient Rings


How old are Saturn's rings? No one is quite sure. One possibility is that the rings formed relatively recently in our Solar System's history, perhaps only about 100 million years ago when a moon-sized object broke up near Saturn. Evidence for a young ring age includes a basic stability analysis for rings, and the fact that the rings are so bright and relatively unaffected by numerous small dark meteor impacts. New evidence, however, raises the possibility that some of Saturn's rings may be billions of years old and so almost as old as Saturn itself. Inspection of images by the Saturn-orbiting Cassini spacecraft indicates that some of Saturn's ring particles temporarily bunch and collide, effectively recycling ring particles by bringing fresh bright ices to the surface. Seen here, Saturn's rings were imaged in their true colors by the robotic Cassini in late October. Icy bright Tethys, a moon of Saturn likely brightened by a sandblasting rain of ice from sister moon Enceladus, is visible in front of the darker rings.

Reflections on the 1970s


The 1970s are sometimes ignored by astronomers. In particular, this beautiful grouping of reflection nebulae in Orion - NGC 1977, NGC 1975, and NGC 1973 - are usually overlooked in favor of the substantial glow from the nearby stellar nursery better known as the Orion Nebula. Found along Orion's sword just north of the bright Orion Nebula complex, these reflection nebulae are also associated with Orion's giant molecular cloud about 1,500 light-years away, but are dominated by the characteristic blue color of interstellar dust reflecting light from hot young stars. North is down in this sharp color telescopic image from New South Wales, Australia, so the more familiar Orion Nebula borders the top of the view. NGC 1977 stretches across the field just above center, separated from NGC 1973 (below left) and NGC 1975 (below right) by darker regions of obscuring dust. Many northern hemisphere observers claim to see the general shape of a running man in the cosmic dust cloud but, of course, they're looking at the view upside down.

Britney Spears Out of Hospital!!!

Back home, Britney Spears spent the early part of Saturday with dad Jamie after being released from Cedars-Sinai hospital, PEOPLE has confirmed.

Spears's mom Lynne, who yesterday called for prayers for the embattled singer, remains in their hometown of Kentwood, LA.

Spears left the Los Angeles medical facility Saturday via an underground tunnel and was accompanied by TV therapist Dr. Phil, according to etonline.com, who first reported the news.

A Cedars-Sinai spokesperson declined to comment, but Dr. Phil released a statement to ET saying: "My meeting with Britney and some family members this morning in her room at Cedars leaves me convinced more than ever that she is in dire need of both medical and psychological intervention.

"She was released moments before my arrival and was packing when I entered the room. We visited for about an hour before I walked with her to her car."

Spears had been committed early Friday morning under California's "5150 Hold," in which Spears was deemed a danger to herself and could be held for 72 hours. Patients however can be released early if doctors determine they are no longer a threat to themselves.

"The 5150 legality is very loose," says Dr. Nathan Kuemmerle, a West Hollywood psychiatrist. "The 72 hours are not firm. All it requires is an ER psychiatrist to release the patient. ... If Britney isn't suicidal or homicidal, she doesn't need to be hospitalized."

Horizon to Horizon

Click on image to see much larger version.
Journey from horizon to horizon as your gaze sweeps through the zenith in the night sky over Beg-Meil, France. Recorded on December 13th, the entertaining panorama (image key) covers 210 degrees in 21 separate exposures, beginning on the beach with bright star Sirius rising in the southeast. Look up (pan right) to encounter the nebula rich constellation of Orion and continue on to find the lovely Pleiades star cluster. Farther along, higher in the sky, is the famous Comet Holmes, still gracing the northern hemisphere's night with its remarkable expanding coma. Finally, just before diving into the urban glow from city lights along the northwestern horizon (far right), check out the double star cluster in Perseus and take in the cosmic streak of a bright Geminid Meteor.

Smooth Skin

This simple little Photoshop tutorial will show you how to edit people's faces to smooth out their skins, just like how models are edited in magazines.


To start off, lets open up the picture you want to edit. I'm working from an Angelina Jolie photo of course.

First, we need to duplicate the layer, so lets go ahead and right click on the layer in the layers palette and select "Duplicate Layer".


Now we need to select the area we want to smooth out, in this case, we want to smooth out the face, but we want to leave the eyes, nose and mouth intact so it looks genuine. So start by switching to the quick mask mode by clicking on the "Edit in Quick Mask Mode" button in the tool box.

Then select the Brush Tool, and set the brush size to 35 soft edge. (brush size will depend on your image).

Press "D" to reset your colors. Now use your brush and paint over the face, the painted area will become your selected area. The painted area will be red as you can see below. Continue and paint around her face until its covered like mine. You may need to change your brush size to a smaller size to cover the tighter areas.


Tip: If you accidentally paint outside the area you want, press "X" (switches colors), then just go over the area you want to erase, then press "X" again to go back to painting your selection.

Now that you have selected your area in quick mask mode, exit the quick mask mode by pressing "Q" or clicking on the "Standard Mode" button (Next to the Edit in Quick Mask Mode button)


Now you should have a selection, around the face.

Now, go to Select->Inverse, then Select->Feather, and enter about 10px.
Tip: You can hide the "Marching Ants" lines so you can have a better view of the image by pressing "CTRL+H"

Now go to Filter->Blur->Guassian Blur. Set radius to about 3 pixels.


That is looking too smooth, which make it look rather unrealistic, so lets put some texture back into the skin. Go to Filter->Noise->Add Noise. For amount, put about 2.5%, Uniformed and Monochromatic selected.

That's it. Here are the original and edited version side by side.















I see a million of these simple tricks executed in print when I'm waiting in line at the grocery store staring at dozens of magazines, all fake faces and fake bodies, all displaying totally false versions of the actresses on the covers. Here's another sample of Nicollette Sheridan, Before and After:
































So have fun doing this to your own photos, it's a quick and easy way to make yourself look younger!
