That is a big Volkswagen.
In Soviet Russia, Nigel makes plans for you!
That the religious zealots will discount this as 'false information' since God created everything and science is all just a bunch of baloney. It happened with carbon dating, dont'cha know?
Creation, you say? Interesting...
Can we invade them for oil? take over their population, oust their government and continue to wage war on their surface for another decade?
no?
pfft. what use are they then?
Why are the scientists sure that the Kuiper Belt holds reminants of the big bang? Comets are made of ice, but they aren't considered building blocks. This is interesting nonetheless and I hope we can use this to help prove(or disprove) a theory or two.
"The three small objects the astronomers spotted - given the prosaic names 2003 BF91, 2003 BG91 and 2003 BH91 - range in size from 15 to 28 miles
Hence the size of Philadelphia varies from 15 to 28 miles. Oh, and Philadelphia is a also an irregular sphere.
I would fond it interesting how the scientists can be sure that there objects have originated when our solar system was created. Wouldn't it be also possible that the asteroids traveled vast distances, having originated in stellar events far away, and eventually gor captured by sub's gravity? This would be even more interesting for us, wouldn't it. I just would like to know if it would be feasible to launch a probe to one of those objects, as to look of what materials it is composed. But can you hit an object that small across this distance and, even more land a probe safely there?
".Sig Stealer" was here
I, for one, welcome our new Plutonian overlords. We are very thankful that our new rulers did not come from Uranus.
The article goes on to say: ... "This is a sign that perhaps the smaller planetesimals have been shattered into dust by colliding with each other over the past few billion years."
"Discovering many fewer Kuiper Belt Objects than was predicted makes it difficult to understand how so many comets appear near Earth since many comets were thought to originate in the Kuiper Belt,"
Wasn't there a NASA theory about space junk threshold and how big bits collide and divide into smaller bits which in turn divide etc...
could this be what happened at the edge of our Solar System?
Excuse me, Sir :
In Armageddon, the meteor was "as big as Texas", now, this one is "roughly the size of Philadelphia".
Now, for the non-US guys here, could you translate ?

Solar system 'fossils' discovered by Hubble Telescope
PHILADELPHIA -- Astronomers using NASA's Hubble Space Telescope have discovered three of the faintest and smallest objects ever detected beyond Neptune. Each lump of ice and rock is roughly the size of Philadelphia and orbits just beyond Neptune and Pluto, where they may have rested since the formation of the solar system 4.5 billion years ago. The objects reside in a ring-shaped region called the Kuiper Belt, which houses a swarm of icy rocks that are leftover building blocks, or "planetesimals," from the solar system's creation.
The results of the search were announced by a group led by Gary Bernstein of the University of Pennsylvania at today's meeting of NASA's Division of Planetary Sciences in Monterey, Calif.
The study's big surprise is that so few Kuiper Belt members were discovered. With Hubble's exquisite resolution, Bernstein and his co-workers expected to find at least 60 Kuiper Belt members as small as 10 miles in diameter -- but only three were discovered. "Discovering many fewer Kuiper Belt Objects than was predicted makes it difficult to understand how so many comets appear near Earth since many comets were thought to originate in the Kuiper Belt," said Bernstein, associate professor of physics and astronomy at Penn. "This is a sign that perhaps the smaller planetesimals have been shattered into dust by colliding with each other over the past few billion years." Bernstein and his colleagues used Hubble to look for planetesimals that are much smaller and fainter than can be seen from ground-based telescopes. Hubble's Advanced Camera for Surveys was pointed at a region in the constellation Virgo over a 15-day period in January and February. A bank of 10 computers on the ground worked for six months searching for faint moving spots in the Hubble images. The three small objects the astronomers spotted - given the prosaic names 2003 BF91, 2003 BG91 and 2003 BH91 - range in size from 15 to 28 miles and are the smallest objects ever found beyond Neptune. At their current locations, these objects are a billion times fainter than the dimmest objects visible to the naked eye. But an icy body of this size that escapes the Kuiper Belt to wander near the sun can become visible from Earth as a comet as the wandering body starts to evaporate and form a surrounding cloud. Astronomers are probing the Kuiper Belt because the region offers a window on the early history of our solar system. The planets formed more than 4 billion years ago from a cloud of gas and dust that surrounded the infant sun. Microscopic bits of ice and dust stuck together to form lumps that grew from pebbles to boulders to city- or continent-sized planetesimals. The known planets and moons are the result of collisions between planetesimals. In most of the solar system, all of the planetesimals have either been absorbed into planets or ejected into interstellar space, destroying the traces of the early days of the solar system. Around 1950, Gerard Kuiper and Kenneth Edgeworth proposed that in the region beyond Neptune there are no planets capable of ejecting the leftover planetesimals, so there should be a zone, now called the Kuiper Belt, filled with small, icy bodies. Despite many years of searching, the first was not discovered until 1992; nearly 1,000 have since been discovered from telescopes on the ground. Most astronomers now believe that Pluto, discovered in 1930, is in fact a member of the Kuiper Belt. Astronomers now use the Kuiper Belt to learn about the history of the solar system, much as paleontologists use fossils to study early life. Each event that affected the outer solar system -- such as possible gravitational disturbances from passing stars or long-vanished planets -- is frozen into the properties of the Kuiper Belt members that we see today.
If the Hubble telescope could search the entire sky, it would find perhaps a half-million pla

" Where the fuck did I mention iraq?"
The handful of protesters and their allies in the left-wing media made quite clear their idea that the retaliation against Iraqi aggression was really "invading them for oil".
Guilty mind? What is there to be guilty about!
"Now, for the non-US guys here, could you translate ?"
That's roughly 5 miles wide, give or take a few feet. Weighs a lot of hogs-heads too. If you hold on, I can get you the measurements in furlongs.
So that's where Darl McBride and the rest of SCO are from!
Hadn't we better start checking what we see in that Hubbard Telescope?
Comets are as much the remnants of the formation of teh solar system as the belt is. In fact, I would go as far as to say that the belt is in face a string of comets whicha re being held in place by centripetal forces. Asteroid belts and such tend to hang around for that very reason. It's the natural order of things. Everything is in a constant state of transition and by definition, once it reaches a more stable state, it is inclined not to leave that state, but remain in a state of stability. Thus, when the comets which reach the state of being in this belt, they are in a mroe stable state and tend to stay in it, compelled by the centripetal force to orbit regularly. Other comets which don't reach that state are more likely to collide with planets and such, since the stable belt is mainly stable due to the non-interferance of other spatial bodies such as the gravity of planets and their moons or other comets or meteors, asteroidsa and the other celestial "brik-a-brak" floating around in space. So when they are in the belt, they tend to remain in the belt and not to collide and be subsequently absorbed by planets and such. That's why we see these belts. They have stood the test of time. There are so many comets out there that if it weren't for these glimpses into the huge belts that lie in and outside of our solar system, we could nearly assume that the comets are as dense everywhere. Of course, that's not true because planets and moons invariably have gravity which attracts them, which is why you'll see quite a large number of craters on planets and very few regular comets which come close to them. Maybe that's why it's such a big occasion for us, when a regular comet like Halley's comet. Well, that's just my 0.02 money units.
" They may be roughly the same size as Philadelphia, but I'm sure they'll win a Stanley Cup before WE do. "
But of course. They will change the face of the NHL forever, as they have had millions of years of hockey experience: these icey planetoids are really nothing but hockey rinks.
In other news, Mike Illitch has launched a space probe that is expected to drop a dead octopus on one of these icy surfaces by the year 2017.
This could be bad news for the New Horizons (Pluto-Kuiper Belt) mission, which plans to visit some as-yet undiscovered Kuiper belt objects after swinging by Pluto - but if there are a lot fewer than first thought..
Discovering many fewer Kuiper Belt Objects than was predicted makes it difficult to understand how so many comets appear near Earth since many comets were thought to originate in the Kuiper Belt,..
"You lied to me! There is a Swansea!"
Each lump of ice and rock is roughly the size of Philadelphia
:P
Does the Google calculator convert between Philadelphia's and metric units for us non-Americans?
"That's right. It was actually because Saddam was in league with Bin Laden in the plotting of the Sept11 atrocity ...That's apparently what 70% of Americans believe according to a recent poll"
The bad thing is that it is not 100%.
"Forgive us in the rest of the world for being a bit cynical and believing the American public has been deceived by its administration and media."
That are just cynical because they do not know the facts.
Coca-cola , McDonalds etc until they get all nice and fat.
To stop terrorism, of course, as Saddam Hussein was a major source of it. Anti-imperialism was also a goal too, given Saddam's track record of attacking neighboring countries with the goal of annexing them. (he still claimed Kuwait as his own land, and still was committed to the goal of conquest of Israel and extermination of the Israelis).
...Each lump of ice and rock is roughly the size of Philadelphia...
Yeah but how much would they weigh at sea level in metric elephants?
How large is this in Libraries of Congress ?

The objects reside in a ring-shaped region called the Kuiper Belt, which houses a swarm of icy rocks that are leftover building blocks...
In other news, Bob Vila will be demonstrating how to build a solar system from scrap in his series This Old House. Also, a hotel chain in Sweden has threatened to sue God for patent infringement citing illegal use of icy blocks for construction.

"The objects reside in a ring-shaped region called the Kuiper Belt"
So?... They found slightly bigger rocks between all the other rocks?
The reminants of the big bang (or universal black hole collapse, as I like to think of it... but that's nonstandard) would be the background radiation, nothing more.
After the big bang, you had the cooling out of our different forces, the formation of subatomic particles, the formation of Hydrogen atoms, and then the formation of giant stars.
Those stars all exploded long ago, creating the wealth of other elements that we see today. Life may or may not have formed at that time, but if it did, it is my guess that all such lifeforms would have been destroyed in the supernovaes of the first generation of stars. Our solar system formed from the exploded remains of one or more of those.
All of which makes these fossils impressively old, the moreso because it is not inconcievable to me that bacteria could predate planetary formation. It would indeed be interesting to look at them, and see what we see.

So how much does that weigh in clouds?
" Why would the US administration be strongly opposed to US imperialism ?"
It certainly is. That is why there is no US imperialism since before World War 2.
When I was a kid there were 9 planets, the asteriod belt a few moons and we were happy with it. Now with this new fangled Hubble stuff they're finding new spitwads everyother damn day. This ones' the size of Bangor Maine, that one's the result of two K Mart parking lot sized iceballs crashing into each other. What the f---?
Very funny :D

4. ???
5. Profit!!
It seems than it is an indication of an another planet. What else could kick out the commets from the Belt if there are so few of the candidates? I wander if this possibility is excluded from gravitational influences on Pluto's trajectory.
I just wondered while reading this article, for no particular reason, what it would take to make Jupiter (or any massive gas giant circling a star) gain enough mass to ignite into a star? The collision of Saturn, Uranus and Neptune with Jupiter? The sum of all the rest mass of all the solar system? I was wondering this as I'm tired as hell and not thinking clearly and came across the thought that that could be how binary and ternary stellar systems are created: With a gas giant gaining enough mass (Jupiter acts as a giant comet screen for the inner planets in any case) to eventually ignite.
Were any of you under the impression they might have found fossils of organisms not of some rock?
I challenge the idea of calling these fossils. If that is the case, I have a bunch of fossils in my driveway.
" Not to further the O/T trollishness here, but invasion necessarily implies aggression, does it not"
Not if the invasion is in retaliation for repeated attacks.
Or do you also think that the allies were aggressive during the 1940s when they pushed the Nazis past the German border?
But are the cheesesteaks any good?
> It certainly is. That is why there is no US imperialism since before World War 2.
Pfft, don't cloud the argument with facts! Let us continue with our ignorant use of the word "imperialism" without anything to back it up! What's wrong with you, man?
Some answers to posted questions from the one who did the research & wrote the press release:
How do we know these things came from our Solar System and not another one? The response about the directions of orbits is good; all the Kuiper Belt Objects (KBOs) and all the known planets orbit in the same direction around the Sun. Wouldn't happen if things were falling in randomly, so almost certainly reflects the rotation of the disk of gas & dust from which our solar system formed. Also, why would it be any easier to make a chunk of ice/rock around another star and have it accidentally caught be our star thousands of light years away, then to just make it around our star? There are grains of dust moving through our Solar System that appear to come from interstellar space, but no big chunks.
Another posts said that comets are the true fossils; in fact short-period comets (including the ones targeted by the spacecraft) are believed to be escapees from the Kuiper Belt. Comets are being evaporated by the Sun (that's why they look so big, they have clouds around them) and so they'll evaporate to nothing but rubble in 10,000 years or so. Not very long by astronomy standards. So there must be unborn comets in "cold storage" somewhere far from the Sun.
The New Horizons mission to Pluto & Kuiper Belt object(s) is alive & kicking. Our discovery means it will be a little harder to find a Kuiper Belt target for them to hit, but it should still be possible. There probably is a dust cloud associated with the Kuiper Belt (debris from collisions), which is doughnut-shaped, but this cloud is not very dense and won't be a threat to the spacecraft. Space is very empty, even in a "crowded" neighborhood like the inner Solar System.
The Nazis used "terrorism" as an excuse to invade Austria. They claimed invasion was the only way to secure Germany's defense. Amusing parallel, I think.
I mean, on most maps it is two-dimensional, but it must have some depth. After all, the planetesimals are three-dimensional. We need to establish volume.
Do we just consider the surface elevation variation, plus the height of any buildings?
What about the airspace overhead? I'm pretty sure we wouldn't consider outer space, but how much of the atmosphere should be included?
What about depth? Only as deep as the deepest subterranean pipeline? The depth of the earth's crust? Does it go all the way to the core? If it's the latter, then it's quite large after all.
Is it worth shelling out an additional 87 billion dollars? With the economy on the rocks? Consumer spending in hole. How about the lives of U.S. soldiers and Iraqi civilians?
When things get bad enough, people rebel. Things obviously weren't bad enough.
Meanwhile, at home, we'll get to see if things are bad enough here to throw the Bush Administration out. Maybe, and maybe not.
They owe us for their liberation and all. I would recommend cheap oil. They have so much of it and all. In fact, it's the second largest known oil reserve and is mostly untapped. I'm sure Haliburton could help them get it out of the ground and everything. Come on Iraq... play ball!
How many volkswagons to a Philadelphia anyway? Or do we only use Volkswagons if it enters the earth's atmosphere? This is so confusing. I can't help but think that metric would be useful here.
-Hope
" The Nazis used "terrorism" as an excuse to invade Austria. They claimed invasion was the only way to secure Germany's defense. Amusing parallel, I think."
The only Nazi-era parallel is that of Bush and Blair to FDR and Churchill.
" You are SO right. Its not about the oil. Its about the military contracts for haliburton"
It has nothing to do with that either. If you knew anything about Haliburton or oil, you would know that they are the best company for cleaning up Saddam's mess.
Finally, you don't need to land a probe on these objects to figure out what they are made of. Optical spectroscopy has done a pretty good job of figuring out what these things are made of, you don't need to send a probe to figure it out. I can tell you right now, the composition is most likely 95-98% water with the rest being a smattering of carbon and nitrogen bearing modules with some silicate particles thrown in to the mix.

books like the Jehovah's Witnesses Creation book.
Oh great another unit of measurement. I already have a hard time converting US Standard to metric, much less elephants, LOCs, and VWs. Now this.
Are these -very faint- planitesimals actually plutinos (in pluto-like resonant orbits with the gas-giants)?
It didn't even say how far out they are. Are they in the range of Quauor, or more likely, Hubble couldn't resolve them if they were even that far out. Are they in the kind of range as pluto?
Does anyone know of a source with further information than the little linked blurb?
The big question is whether they could spot any Toynbee Tiles inlaid in the remnants?
> Why would the US administration be strongly opposed to US imperialism ?
I think he meant to say "opposed to competing imperialism".
Sheesh, evil *and* a jerk. -- Jade
The objects reside in a ring-shaped region called the Kuiper Belt, which houses a swarm of icy rocks that are leftover building blocks, or "planetesimals," from the solar system's creation.
This is nothing but pseudo-scientific drivel. These objects *may* be "leftover building blocks" from the formation of the Solar system, or they may not.
The fact is that we have no way of knowing. It's sloppy, unsubstantiated claims like this that (justifiably) undermine the credibility of those making such claims. Such bogus science consequently leads many of us to question the validity of the church of evolution on purely scientific grounds, if nothing else...

"The earth is flat! I have seen it with my own eyes! The infadels spread lies! Look at the moon at night, thus everyone knows the moon is shaped flat like Iraq's golden coins! Every star in the sky is the award Alah gives his people for following him! Even the infadels confirm this truth when their Hubble Telescope discovers more of Alah's stars in the sky! This confirms everything; our planet and the moon is flat and round like Iraq's golden coins, and as well all the stars in the sky are the awards of Alah's servants! Praise to Alah! We will cut out the tongues of every infadel that speaks!"

That'll give the world some incentive to fund space research.
Just make some space ships with powerful lazers and blow away some asteroids.
Now that is something worth funding!

"Neither the belief in spontaneous generation nor phrenology were the product of science."
Yes, they were part of the history of science. Just because they look so embarassing today does not mean that they were not.
"Quit your republican fantasizing. I didn't support the war, don't support it now, and am proud of both facts."
You support the war, but it is clear that you only support Saddam's side, and think it was fine that he killed 10,000+ people a year. Why else would you oppose effective efforts to stop him and his war.
"save face....I voted against Bush in both the primary and the general election"

Nothing to make up here; that has been the main goal.
"the glaring absence of the WMDs and terrorist connections that were used to justify it."
He had the WMD's just before the US retaliation. The only question is where they went. Terrorist connections? These are quite evident, from his hosting of terrorist camps to his aggression against Israel.
Thankfully, your "pro-Saddam" wing with its glaring ignorance of foreign affairs is in a minority and has little influence, even at a time when people like Howard Dean gain some celebrity with their bold and bald-faced lies about Iraq.
"I think he meant to say "opposed to competing imperialism"."
No, the US administration is opposed to any imperialism of any kind, including its own (the latter is easy enough, since the US government has not been imperialist in any way for decades)
I looked at that website, and its the same old young-Earth creationism drivel taht's been making the rounds for decades. No integrity, no credibility, and no science.
Helium balloons want to be free.
The text I use is The New Oxford Annotated Bible with the Apocrypha (aka the New Revised Standard Version). It is a direct descendent of the Revised Standard Version, the Bible with the distinction of being officially authorized by all major Christian churches: Protestant, Anglican, Roman Catholic, and Eastern Orthodox. It is the translation preferred by biblical scholars. In the commentary on Gen2:4b-25, the editors say "This is a different tradition from 1.1-2.3 as evidenced by the flowing style and the different order of events of creation." So when you argue that there are no inconsistencies, you are disagreeing with the National Council of the Churches of Christ, the body that authorized this translation. If it comes to a choice between believing either a body of scholars from the major Christian Churches and a Jewish scholar (for the Old Testament) or a /. troll, I'll side with the scholars.

Then you didn't look at all. There's quite a bit there, and the first time through, it took me over a week to read through just the archives of the Disclosure articles. There is indeed quite a bit of science there, much of it quoted form evolutionist journals...
