Rings of Saturn are a bit like in fiction... expect they're only a couple of meters thick and consists rather small rocks and ice chunks.

Well its mostly dust about as fine as cigarette smoke...that's why orbiters can fly through them with mostly no trouble.

Yeah, i should've said "small rocks and ice chuncks at most"

It occurs to me that 2001 A Space Odysseys is probably the only scifi film to portay asteroid belt correctly. That is, the film ignores the asteroids completly.

The most magnetic massive star seen yet is dragging a giant cloak of trapped charged particles around it.

This newly discovered star, NGC 1624-2, could help shed light on what role the magnetism of stars plays in the evolution of stars and their galaxies.

NGC 1624-2, which lies about 20,000 light-years from Earth in the constellation Perseus, has about 35 times the sun's mass. Its hefty mass gives it plenty of fuel, making it bright and hot and thus likely to burn out relatively quickly after a lifetime of about 5 million years, or one-tenth of 1 percent of the sun's current age at midlife.

This massive star possesses a magnetic field 20,000 times stronger than the sun's and nearly 10 times stronger than that detected around any other high-mass star.

Or try to comprehend how the universe was created if nothing existed before. What sparked the big bang? Does time exist in the absence of energy/matter?

A simple analogy would be if you were a 2D being on the surface of a balloon, and the balloon was getting bigger. (Not 100% sure that's an accurate analogy because of the dimensionality of the universe not being locked down, but in terms of spatial dimensions, it should suffice)

It seems as if space is so huge and so unknown that there are extremes on every end. A highly magnetic star? Water floating in space? It's amazing and why I love it.

Warp Drive May Be More Feasible Than Thought, Scientists Say.

warp-drive-starship.jpg
Click to expand...

HOUSTON — A warp drive to achieve faster-than-light travel — a concept popularized in television's Star Trek — may not be as unrealistic as once thought, scientists say.

A warp drive would manipulate space-time itself to move a starship, taking advantage of a loophole in the laws of physics that prevent anything from moving faster than light. A concept for a real-life warp drive was suggested in 1994 by Mexican physicist Miguel Alcubierre, however subsequent calculations found that such a device would require prohibitive amounts of energy.

Now physicists say that adjustments can be made to the proposed warp drive that would enable it to run on significantly less energy, potentially brining the idea back from the realm of science fiction into science.

An Alcubierre warp drive would involve a football-shape spacecraft attached to a large ring encircling it. This ring, potentially made of exotic matter, would cause space-time to warp around the starship, creating a region of contracted space in front of it and expanded space behind.

Meanwhile, the starship itself would stay inside a bubble of flat space-time that wasn't being warped at all.

"Everything within space is restricted by the speed of light," explained Richard Obousy, president of Icarus Interstellar, a non-profit group of scientists and engineers devoted to pursuing interstellar spaceflight. "But the really cool thing is space-time, the fabric of space, is not limited by the speed of light."

With this concept, the spacecraft would be able to achieve an effective speed of about 10 times the speed of light, all without breaking the cosmic speed limit.

The only problem is, previous studies estimated the warp drive would require a minimum amount of energy about equal to the mass-energy of the planet Jupiter.

But recently White calculated what would happen if the shape of the ring encircling the spacecraft was adjusted into more of a rounded donut, as opposed to a flat ring. He found in that case, the warp drive could be powered by a mass about the size of a spacecraft like the Voyager 1 probe NASA launched in 1977.
Furthermore, if the intensity of the space warps can be oscillated over time, the energy required is reduced even more, White found.

White and his colleagues have begun experimenting with a mini version of the warp drive in their laboratory.

They set up what they call the White-Juday Warp Field Interferometer at the Johnson Space Center, essentially creating a laser interferometer that instigates micro versions of space-time warps.

"We're trying to see if we can generate a very tiny instance of this in a tabletop experiment, to try to perturb space-time by one part in 10 million," White said.

So awesome, I wish I could be alive a few centuries from now....so much I'll never know; so much I'll never see. Though, I suppose every generation feels like this.

You never know, just one breakthrough in medical science... you only need to live long enough till the next breakthrough...

This is pretty fing awesome though, I always figured with enough time and knowledge we'd get over some of the limits we find today, checking out the world in just a few hundred years would be amazing.

How in the hell do you go from Jupiter size to probe size with a slight change to the ring?

I mean when designing craft you usually try different shapes to begin with?

Wasn't sure what exactly I was supposed to be seeing here. Read some info on the sight:

The Dark Energy Survey (DES) is designed to probe the origin of the accelerating universe and help uncover the nature of dark energy by measuring the 14-billion-year history of cosmic expansion with high precision. More than 120 scientists from 23 institutions in the United States, Spain, the United Kingdom, Brazil, and Germany are working on the project. This collaboration is building an extremely sensitive 570-Megapixel digital camera, DECam, and will mount it on the Blanco 4-meter telescope at Cerro Tololo Inter-American Observatory high in the Chilean Andes. Starting in Sept. 2012 and continuing for five years, DES will survey a large swath of the southern sky out to vast distances in order to provide new clues to this most fundamental of questions.

Oh I thought you guys are familiar with it.

Now I still don't understand. A super camera for what? Taking nice pictures?

Taking pictures for measuring purposes, a look into the past, accelerating universe etc.
It's going to be lot's of data, plus at a high precision and quality.

I understand the principal of Dark Energy, but it's not very clear what's to be ascertained from the two images you posted.
