|Epic Discovery: China's National Radio-Astronomy Observatory Announces Monitoring of 'Dark' Satellite in Orbit Around Saturn - "Transmitting the Universal Genetic Code"
China's Xinhua News Agency, the official press agency of the government of the People's Republic of China (PRC) announced Thursday that the National Radio Astronomy Observatory has been monitoring signals from a previously unknown "dark" satellite in orbit around Saturn for the past 90 days. According to government officials, the signals appear to be the first verified transmission from an alien civilization.
China's leading astrobiologist, Dr. Xi Chang, a graduate of MIT, told Xinhua that "the sigal repeats itself continuosly in 2 minute long sequences and appears to be the four bases of the genetic code A,G, U and C that ribosomes must convert mRNA sequences into proteins and the twenty different amino acids that proteins are comprised of."Dr. Rosie Redfield, the newly appointed director of the Astrobiology Program at NASA Headquarters, Washington, confirmed China's dicovery this morning. In a press release Redfield said that "China's discovery has monumental consequences, and has been shared with the world's premier scientific instituions for vetting and peer review. If confirmed this will be the first proof of extraterrestrial life in the universe and confirmation that our DNA basis for life may be universal throughout the known universe."
"The information transfer from DNA to protein, called gene expression , occurs in two steps. In the first step, called transcription , a DNA sequence is copied to make a template for protein synthesis called messenger ribonucleic acid -messenger RNA, or mRNA. During protein synthesis, ribosomes and transfer RNA (tRNA) use the genetic code to convert genetic information contained in mRNA into functional protein. Formally speaking, the genetic code refers to the RNA-amino acid conversion code and not to DNA, though usage has expanded to refer more broadly to DNA.
Redfield added that NASA expects a more detailed press conference to be held at the White House later today or tomorrow, pending announcement from the Obama administration.
Dr. Dimitri Kardashev of the Harvard-Smithsonian Center for Astrophysics told The Daily Galaxy that "This discovery comes as no surprise to me. It was always just a matter of time. The Earth is only some four billion years old. Our universe is some 14 billion years old. There may be millions of advanced technological civilizations that are billions of years older than ours. Keep in my that the radio was only invented 120 years ago. Quantum computers and singularity are at most two or three gereration distant. The technologies of ET civilizations a million years old and older are beyond our comprehension."
Sir Martin Rees, a leading Cambridge University cosmologist and astrophysicist who is the president of Britain's Royal Society and astronomer to the Queen of England, said: “I suspect there could be life and intelligence out there in forms we can't conceive. Just as a chimpanzee can't understand quantum theory, it could be there are aspects of reality that are beyond the capacity of our brains.”
With the help of NERSC systems, she successfully validated her method by analyzing the radio observations of the Whirlpool Galaxy, which has a visible satellite one-third of its size, and NGC 1512, which has a satellite one-hundredth its size. Her calculations correctly predicted the mass and location of both of the known satellite galaxies.

|Research: April's Fools Day joke or not?
Sunday April 3 2011
Okay now this is weird .. i've checked all the references named in the article in the order they are mentioned and they are all valid, thats a lot of effort looking all of that up for just an April's Fools Day joke. It all matches, just nothing 2 b found about the discovery (except many copies of the same article) so the discovery is the only thing invalid?? .. strange ..
U can check the references here (i've looked them al up):

Saturn is sending out mixed signals in recent data from NASA's Cassini spacecraft and the NASA/ESA Hubble Space Telescope. › Download video
Like a petulant adolescent, Saturn is sending out mixed signals.
Recent data from NASA's Cassini spacecraft show that the variation in radio waves controlled by the planet's rotation is different in the northern and southern hemispheres. Moreover, the northern and southern rotational variations also appear to change with the Saturnian seasons, and the hemispheres have actually swapped rates. These two radio waves, converted to the human audio range, can be heard in a new video available online at: http://www.nasa.gov/multimedia/videogallery/index.html?media_id=74390781
"These data just go to show how weird Saturn is," said Don Gurnett, Cassini's radio and plasma wave science instrument team lead and professor of physics at the University of Iowa, Iowa City. "We thought we understood these radio wave patterns at gas giants, since Jupiter was so straightforward. Without Cassini's long stay, scientists wouldn't have understood that the radio emissions from Saturn are so different."
Saturn emits radio waves known as Saturn Kilometric Radiation, or SKR for short. To Cassini, they sound a bit like bursts of a spinning air raid siren, since the radio waves vary with each rotation of the planet. This kind of radio wave pattern had been previously used at Jupiter to measure the planet's rotation rate, but at Saturn, as is the case with teenagers, the situation turned out to be much more complicated.
When NASA's Voyager spacecraft visited Saturn in the early 1980s, the radiation emissions indicated the length of Saturn's day was about 10.66 hours. But as its clocking continued by a flyby of the joint ESA-NASA Ulysses spacecraft and Cassini, the radio burst varied by seconds to minutes. A paper in Geophysical Research Letters in 2009 analyzing Cassini data showed that the Saturn Kilometric Radiation was not even a solo, but a duet, with two singers out of sync. Radio waves emanating from near the north pole had a period of around 10.6 hours; radio waves near the south pole had a period of around 10.8 hours.
A new paper led by Gurnett that was published in Geophysical Research Letters in December 2010 shows that, in recent Cassini data, the southern and northern SKR periods crossed over around March 2010, about seven months after equinox, when the sun shines directly over a planet's equator. The southern SKR period decreased from about 10.8 hours on Jan. 1, 2008 and crossed with the northern SKR period around March 1, 2010, at around 10.67 hours. The northern period increased from about 10.58 hours to that convergence point.
Seeing this kind of crossover led the Cassini scientists to go back into data from previous Saturnian visits. With a new eye, they saw that NASA's Voyager data taken in 1980, about a year after Saturn's 1979 equinox, showed different warbles from Saturn's northern and southern poles. They also saw a similar kind of effect in the Ulysses radio data between 1993 and 2000. The northern and southern periods detected by Ulysses converged and crossed over around August 1996, about nine months after the previous Saturnian equinox.
Cassini scientists don't think the differences in the radio wave periods had to do with hemispheres actually rotating at different rates, but more likely came from variations in high-altitude winds in the northern and southern hemispheres. Two other papers involving Cassini investigators were published in December, with results complementary to the radio and plasma wave science instrument -- one by Jon Nichols, University of Leicester, U.K., in the same issue of Geophysical Research Letters, and the other led by David Andrews, also of University of Leicester, in the Journal of Geophysical Research.
In the Nichols paper, data from the NASA/ESA Hubble Space Telescope showed the northern and southern auroras on Saturn wobbled back and forth in latitude in a pattern matching the radio wave variations, from January to March 2009, just before equinox. The radio signal and aurora data are complementary because they are both related to the behavior of the magnetic bubble around Saturn, known as the magnetosphere. The paper by Andrews, a Cassini magnetometer team associate, showed that from mid-2004 to mid-2009, Saturn's magnetic field over the two poles wobbled at the same separate periods as the radio waves and the aurora.
"The rain of electrons into the atmosphere that produces the auroras also produces the radio emissions and affects the magnetic field, so scientists think that all these variations we see are related to the sun's changing influence on the planet," said Stanley Cowley, a co-author on both papers, co-investigator on Cassini's magnetometer instrument, and professor at the University of Leicester.
As the sun continues to climb towards the north pole of Saturn, Gurnett's group has continued to see the crossover trend in radio signals through Jan. 1, 2011. The period of the southern radio signals continued to decrease to about 10.54 hours, while the period of the northern radio signals increased to 10.71 hours.
"These papers are important in helping to explain the complicated dance between the sun and Saturn's magnetic bubble, something normally invisible to the human eye and imperceptible to the human ear," said Marcia Burton, a Cassini fields and particles scientist at NASA's Jet Propulsion Laboratory, Pasadena, Calif., who was not involved in the work. "Cassini will continue to keep an eye on these changes."
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. JPL, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The radio and plasma wave science team is based at the University of Iowa, Iowa City, where the instrument was built. The magnetometer team is based at Imperial College, London, U.K.
The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA's Goddard Space Flight Center manages the telescope. The Space Telescope Science Institute conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy, Inc., in Washington, D.C.
