XDF (eXtreme Deep Field) Hubble image. One of the most amazing images in human achievement. This photo contains light over 13 billion years old. And it's only just one little bitty patch of the visible night sky.

The universe is ****ing endless....

Hubble Goes to the eXtreme to Assemble Farthest-Ever View of the Universe

Hubble pointed at a tiny patch of southern sky in repeat visits (made over the past decade) for a total of 50 days, with a total exposure time of 2 million seconds. More than 2,000 images of the same field were taken with Hubble's two premier cameras: the Advanced Camera for Surveys and the Wide Field Camera 3, which extends Hubble's vision into near-infrared light.

"The XDF is the deepest image of the sky ever obtained and reveals the faintest and most distant galaxies ever seen. XDF allows us to explore further back in time than ever before", said Garth Illingworth of the University of California at Santa Cruz, principal investigator of the Hubble Ultra Deep Field 2009 (HUDF09) program.


The universe is 13.7 billion years old, and the XDF reveals galaxies that span back 13.2 billion years in time. Most of the galaxies in the XDF are seen when they were young, small, and growing, often violently as they collided and merged together. The early universe was a time of dramatic birth for galaxies containing brilliant blue stars extraordinarily brighter than our sun. The light from those past events is just arriving at Earth now, and so the XDF is a "time tunnel into the distant past." The youngest galaxy found in the XDF existed just 450 million years after the universe's birth in the big bang.

Before Hubble was launched in 1990, astronomers could barely see normal galaxies to 7 billion light-years away, about halfway across the universe. Observations with telescopes on the ground were not able to establish how galaxies formed and evolved in the early universe.

Hubble gave astronomers their first view of the actual forms and shapes of galaxies when they were young. This provided compelling, direct visual evidence that the universe is truly changing as it ages. Like watching individual frames of a motion picture, the Hubble deep surveys reveal the emergence of structure in the infant universe and the subsequent dynamic stages of galaxy evolution.

Better way to turn ocean into fuel

UOW scientists have developed a novel way to turn sea water into hydrogen, for a sustainable and clean fuel source.

Using this method, as little as five litres of sea water per day would produce enough hydrogen to power an average-sized home and an electric car for one day.

The research team at UOW’s Australian Research Council Centre of Excellence for Electromaterials Science (ACES) have developed a light-assisted catalyst that requires less energy input to activate water oxidation, which is the first step in splitting water to produce hydrogen fuel.

A major limitation with current technologies is that the oxidation process needs a higher energy input, which rules out using abundant sea water because it produces poisonous chlorine gas.

The research team, led by Dr Jun Chen and Professor Gerry Swiegers, have produced an artificial chlorophyll on a conductive plastic film that acts as a catalyst to begin splitting water.

The results were recently published in the journal Chemical Science.
Lead author, Dr Jun Chen, said the flexible polymer would mean it could be used in a wider range of applications and it is more easily manufactured than metal semiconductors.

“The system we designed, including the materials, gives us the opportunity to design various devices and applications using sea water as a water-splitting source.

“The flexible nature of the material also provides the possibility to build portable hydrogen-producing devices.”

The development brings UOW’s energy research a step closer to creating an artificial leaf-like device that can efficiently produce hydrogen.

ACES Executive Research Director Professor Gordon Wallace said: “In today’s world the discovery of high performance materials is not enough”.

“This must be coupled with innovative fabrication to provide practical high-performance devices and this work is an excellent example of that,” he said.

This one just blows my mind. The defined and reproducible patterns are just amazing. Each frequency is unique. Couple that with the fact that everything in the universe is vibrating. And each frequency of vibration brings its own individual pattern.

What you're watching is the Chladni plate experiment, as performed by YouTube science-and-illusion wizard Brusspup (he can also coax water into a zig-zagging stream, and make Rubik's Cubes that aren't Rubik's Cubes).

When physicist Ernst Chladni performed this experiment in the 18th century, he did it with flour instead of sand, and made his metal plate vibrate with a violin bow instead of a tone generator, but the end result is the same: when the plate vibrates at a steady frequency, the particles on its surface arrange into a beautiful pattern.

The particles (sand, in this case) are arranging themselves along what are called "nodal lines" – narrow curves of motionless calm that criss-cross the otherwise vibrating surface. As the frequency changes, so does the distribution of these nodal lines, which becomes increasingly intricate at higher frequencies.

This is my favorite thread on CP.

Oil companies are sending hitmen to these guy's door as we speak.

There are 1,300,000,000,000,000,000,000 or 1.3sextillion liters of water in the earth's oceans.

Ditto.

Imagine that on a stupid football site?

Ha ha, you're drinking dinosaur piss.....

Oh yeah? Well, I've pissed out in the woods in the Dakotas where there undoubtedly are remains of dinosaurs buried deep under the landing spot of my pee stream. So I have in essence pissed on the creature that pissed in my drinking water millions of years ago.

Mind = blowed up.

And what's worse is we've all drank boar semen . HaHa !

Wu-Tang’s GZA Teaches Kids Science With Least-Lame Classroom Rap Ever

As part of a program created by Columbia professor Christopher Emdin, 10 New York City high school classes have been writing raps as a way to learn about science. The program is called Science Genius, and it sounds like the sort of patronizing pop-culture hijack kids hate more than anything. But when Wu-Tang’s GZA drops by a Bronx classroom to discuss the importance of scientific inquiry, you can see the actual moment when the students realize the program is legit.
