Newly Formed Solar System 117
xPsi writes "An article in New Scientist reports that a team of astronomers from UC Berkeley and NASA's Goddard
Space Flight Center have used the Hubble space telescope to image a dust
ring in orbit around Fomalhaut, a nearby star about 25 light years away.
The ring 'offers the best evidence yet that a nearby star is circled by a
newly formed solar system.' Oddly enough, from the Earth's vantage point,
the ring also happens to resemble The Eye of
Sauron. One Ring to rule them all, one Ring to find them..."

Nah, it's simple. There's so little mass in a ring you could concevably accelerate it pretty goddamn quickly. Strap a few rockets on, aim it well, and fire, and you can lie back for a littel nap.

It's only 25 light years away. If solar sails can be asumed to go "a significant fraction" of light speed (at their best) we can assume that it would take no longer than a few minutes - to the passengers (assuming that a trip of 100,000 light years would take about 3 minutes "to the riders").

You've forgotten about acceleration. Accelerating to 99.9% of light speed (relative to the Sun) in 90 seconds would require an acceleration of about 340,000g. Solar sails don't have that kind of thrust, and you couldn't build a ship or crew to survive it anyway.
(Note that I've done the math using newtonian equations. With relativistic effects the number is bound to be much worse).

We're talking subjective time. As the craft accelerates, its perception of time slows down. If the craft can accelerate fast enough, it can travel 100,000 ly in 3 minutes as measured by an on-board clock. An outside observer, stationary relative to the origin and destination, will measure the time taken as somewhat over 100,000 years.

How does this work? I've read a few books covering relativity (as well as the linked articles), but I still don't understand how one can travel 25 light years in three minutes at near light speed.
The way I understand it, time dilates in a sense for everyone not traveling near light speed. When you approach the speed of light, from your vantage point, you are leaving your point of origin and approaching your destination at the speed of light. The origin and destination, however, will have time pass extraord

No, stationary observers in the frame of your origin and destination will measure 25 years for the trip (minus a little bit because your speed isn't quite c).

If the presence of a planetary system weren't suspected, I doubt they would have gotten orbits to use the HST to observe this.
As for the "newly formed" stuff, it has nothing to do with the Hubble picture. It merely is a speculation based on the fact that the star is A-type star (like Vega) that hadn't evolved too much (I don't remember how old, but it's nowhere near as old as the Sun...) Anyway, add the word "astronomically" in front of "newly formed" to make a better sense out of the phrase.

This dust cloud was first published in 1989 in the Bulletin of the American Astronomical Society.
According to "The Age of Gliese 879 and Fomalhaut" in APJ v.475, p.313 (1997) Fomalhaut is 200 +/- 100 million years old. While this is a large margin of error, this still confirms that circumstellar dust disks can persist in A stars for several hundred megayears, which it is believed can then form planets.
According to Monthly Notices of the Royal Astronomical Society v.334, p.589 (2002) it is estimated that the ring has the mass of 20-30 Earths.
While not known for certain "Submillimeter Observations of an Asymmetric Dust Disk around Fomalhaut" in APJ v.582, p.1141-46 (2003) implies that the ring offset and the clump with 5% the mass of the ring is likely caused by a large planet close to the star, but I don't know what this no-visible-planet observation means for that theory. Dark matter?
And I could not for the life of me find the distance that ring is from Fomalhaut. Anyone know?
And thanks for that link to the Eye of Sauron, I had been wondering what that was.
