samhussey 0 #1 September 2, 2004 I heard on the news today that some eggheads have detected a radio signal from space something like 3 times in the last few days and they're getting quite excited about it. Anyone know anything more on this? Quote Share this post Link to post Share on other sites
adamjenner 0 #2 September 2, 2004 never heard anything about that. is there anything about it on yahoo or cnn's website that we could read about? edit : http://www.mirror.co.uk/news/allnews/tm_objectid=14595205%26method=full%26siteid=50143%26headline=was%2dshgbo2%2d14a%2dthe%2dfirst%2dmessage%2dbeamed%2dfrom%2det%2d-name_page.html and yes i'm TOO lazy to make it "clicky" so suffer through the entire url.

NickDG 23 #3 September 2, 2004 There's a link on this page, but the link seems to be down; http://www.newscientist.com I've had an old IBM 8086 running the SETI program for some time now. It's pretty cool. http://setiathome.ssl.berkeley.edu/download.html Nick BASE 194 Quote Share this post Link to post Share on other sites

samhussey 0 #7 September 2, 2004 This is from the Mirror article. The New Scientist one is (obviously) better, but pretty long... --------------------------------------------------------- MYSTERY SIGNAL COULD BE ET PHONING Sep 2 2004 Mystery of signal from space By Vanessa Allen A RADIO transmission from outer space could be a message from aliens, say astronomers. The signal - named SHGbo2+14a - has been beamed to Earth three times since 2002 and picked up by the giant Arecibo radio telescope in Puerto Rico. Scientists have not been able to properly analyse it as it is only about a minute long and very weak. Experts from the Search for Extraterrestrial Intelligence (Seti) say it is unlikely to be interference or a hoax. Others claim aliens wanting to send messages - like Steven Spielberg's ET who tried to phone home - would transmit via a physical object because radio signals break up during space travel. But Seti researcher Eric Korpela of the University of California, insisted: "We are looking for something that screams out 'artificial'. But I can't think of any way to make a signal like this." The Seti project uses software running as screensavers on millions of computers to sift through the data from the Arecibo telescope. The frequency of the signal is one which experts argue extraterrestrials would be most likely to use if they wanted to make contact, the New Scientist reported.

ChasingBlueSky 0 #9 September 2, 2004 Interesting - I found this article today and was going to ask if this means SETI was a waste? http://news.yahoo.com/news?tmpl=story&cid=573&u=/nm/20040902/od_nm/science_aliens_dc_2&printer=1 Writing Better Than the Phone to Contact ET? Thu Sep 2, 8:20 AM ET LONDON (Reuters) - Writing, rather than phoning, is probably the best way to contact extraterrestrials, American scientists said Wednesday. So instead of phoning home, it could have been more energy efficient if ET had inscribed information and physically sent it, because radio waves disperse as they travel. "Think of a flashlight beam," said Professor Christopher Rose, of Rutgers University in New Jersey who reported his finding in the science journal Nature. "Its intensity decreases as it gets farther from its source. The same is true of the beam of a laser pointer, though the distance is much longer," he added in a statement. Rose and his colleague, physicist Gregory Wright, were pondering how to get the most bits per second over a wireless channel when they concluded that the detectability of a signal diminishes with distance. If the recipient isn't listening or misses it, the message may have to be sent numerous times but a physical message encoded in an object lands somewhere and stays there. Messages from aliens could possibly be embedded in organic material in an asteroid, for example. "If haste is unimportant, sending messages inscribed in some material can be strikingly more efficient than communicating by electronic waves," said Rose._________________________________________ you can burn the land and boil the sea, but you can't take the sky from me....

indyz 1 #10 September 2, 2004 QuoteRose and his colleague, physicist Gregory Wright, were pondering how to get the most bits per second over a wireless channel when they concluded that the detectability of a signal diminishes with distance. Shocking! These guys should write this shit down. It should be a basic principle taught to every student who takes an E/M physics class... I don't see how sending physical objects is more efficient. An object a kilometer across, which would take massive amounts of energy to hurl across interstellar space, could easily be overlooked at it's destination solar system. Even a single highly directional radio beam, which admittedly isn't any easier to find, has the potential to reach hundreds or thousands of stars at a tiny fraction of the cost. But I'm not a physicist, so I'm probably wrong. Quote Share this post Link to post Share on other sites
ChasingBlueSky 0 #11 September 2, 2004 I understand the argument for both - but it sounds like we may need to find a new way to communicate....and then there is that little issue of hoping someone is listening or looking for us. Or then again, maybe they won't be able to see us: Earth to disappear from alien radar By Lucy Sherriff The Earth is gradually vanishing from the view of any aliens that might be looking for us, because we are using fewer technologies that leak radio waves into space. This is the view of one of the pioneers of the SETI project, Frank Drake. (SETI stands for Search for Extra Terrestrial Intelligence, in case you just crash landed.) His remarks cast doubt over the current search methods employed by SETI in their hunt for little green men, but, he says, also suggest a reason for the deafening silence out there. According to New Scientist our transition from radio tranmissions to cable TV could mean that our window of detectability is no more than 100 years. In the 1960's Drake developed an equation that gave researchers a ball park figure of how many planets in the galaxy are home to intelligent, communicating species. One of the factors in the equation is the longevity of the observable communications, now, Drake says, this is substantially reduced. Assuming any hypothetical Aliens have developed at a similar pace to ours, and accounting for the fact that we're looking for a needle in a haystack in the first place, we shouldn't be too disheartened that we've not found anyone out there. Yet. So instead of trying to eavesdrop on unintentional signals, we should be searching for beacons: signals sent to us deliberately. In fact, SETI has begun to do just this, but the activity is very new. ®_________________________________________ you can burn the land and boil the sea, but you can't take the sky from me....
