Spitzer Sees the Aftermath of a Planetary Collision
Universe Today ^ | Jan. 10, 2005 | Dolores Beasley and Gay Yee Hill

Posted on 01/13/2005 8:50:18 PM PST by SunkenCiv

NASA's Spitzer Space Telescope has found a dusty ring of material orbiting nearby Vega which was probably the result of a series of protoplanets smashing into each other. Vega is the fifth brightest star in the sky, located only 25 light-years away in the constellation of Lyra. This dust is constantly being blown out by Vega's intense radiation, so it's unlikely that the star has had this much dust for its entire lifetime. Instead, this ring must have been formed recently, perhaps when a Pluto-sized object was pulverized within the last million years or so.

other versions of the image. CAUTION, the third one is 2.2 megs, and the TIF files are about four times larger than that.

Titan: The New World
CBS Worldwide Inc
Jan. 19, 2005
"The rings are no older than about a few hundred million years. They're young. They are basically geologically young," says Porco. "It means that rings, Saturn's rings, were not in there in the early days when dinosaurs roamed the Earth... [made of] Billions and billions of particles. Countless numbers of particles. Varying ice particles. Varying size from the sizes of houses, large houses or small apartment buildings, down to the sizes of stones and pebbles," says Porco. "And although they're screaming around Saturn at speeds of 40,000 miles an hour, they are very gently jostling each other. They are the delicate wreckage of a moon, or maybe a comet that was ripped apart and captured by Saturn's gravity. Being in charge gives her the privilege of naming the pictures. "Ring World Waiting" was taken more than 17 million miles away. "Side Swiping Saturn" is a view of the seemingly paper-thin ring level view. And "Nature's Canvas" captures Saturn's tiny moon, Mimas. Cassini has discovered three new moons. Now Saturn has 34.

Did I ever show you this topic? Anyway, here's a sort of related story link, which might even make a good topic of its own:
Far-out worlds, just waiting to be found
by Stuart Clark
New Scientist
23 July 2005
IN THE dark reaches of the solar system lurk swarms of hidden worlds. Too small and too distant to reflect sunlight, they have remained under the cover of darkness for billions of years. But now the outer solar system is giving up its secrets. And with them comes an astonishing claim: "It's quite possible that there is a halo of planets surrounding our solar system, just waiting to be found," says Eugene Chiang, an astronomer at the University of California, Berkeley.

What makes Chiang's claim so surprising is the sheer number and size of these planets. Weighing more than Mars, they dwarf Sedna and Quaoar, the largest rocky bodies spotted circling the sun beyond Pluto.

Thank you for the post and the links. This is why some of us do not sleep.

How cool is this.

Discovery's countdown starts Saturday, launch Tuesday morning.

Godspeed to our team.

2:00 am, and I am freeping, watching the X-files and now digging for Immanuel Velikovsky's "worlds In Collision".

The wife is going to beat my arse if I wake her up.

Like I need to read it again...

I do though.

a really cool image first posted on FR by NormsRevenge, topic at the pic-click.
