a laser pulse spatial

Tania sent me an article related to something we've worked this way in CCMC: the study of the universe and the search for intelligent life. Well it seems that we saw the movie Contact earlier this year has an equivalent in real life, in an Australian observatory in which laser pulses have been detected from space. Although it is quite a bombshell, prudence has been in this case (unlike in the movie or the novel by Carl Sagan) a component applied with the utmost rigor. I copy below the post:

Having spent 20 years trying to detect any intelligent extraterrestrial signal, SETI (Search for Extraterrestrial Intelligence ) seems to have achieved its goal: a mysterious laser pulse has been recorded, emerging from random noisy cosmos. This is the kind of event we've been looking for for decades, and it appears that "someone very intelligent is sending a message.

Ragbir Bhathal, an astrophysicist at the University of Western Sydney, in December 2008 found a laser signal from outer space. Bhathal working in Australian facilities SETI (Search for Extraterrestrial Intelligence ), the organization that searches for extraterrestrial intelligence through telescopes . It seems that caution is one of the greatest virtues of the scientist, because instead of running away to report the fact to the press preferred spending almost five months investigating whether there was some kind of error in the instruments, if it was not a physical phenomenon current or was simply " random noise" from space.

Once discarded all possible known sources, Ragbir Bhathal has released their findings. " NASA uses lasers to communicate in space, so it's not so farfetched to imagine that an alien civilization could also use " he says. Send a laser beam to a particular region of space is so simple that we could almost do today, says Paul Horowitz, professor of physics Harvard University. For example, the NOVA laser Lawrence Livermore National Laboratory (California), used in nuclear fission experiments , is capable of producing over one billion watts laser light for a tiny fraction of a second. If might show that beam in a mirror 10 meters as the one on the Keck telescope in Hawaii, we could emit a light 5,000 times brighter than the sun to where we want. We assume that ET is also able to do that.


is too early to attribute this laser light to an extraterrestrial civilization. But SETI is working on it. " In a very real sense, the search for extraterrestrial intelligence is a search for cosmic context of humanity, a search of who we are, where we came from and what possibilities there are for our future " Carl Sagan wrote in the introduction of book "Communication with Extraterrestrial Intelligence (Communication with extraterrestrial intelligence.") If we're lucky, the signal detected by Ragbir Bhathal may contain the answer to this quest for humanity.
