[quote]ARE WE ALONE in the universe? Is there life on other planets? Are there other civilisations in our galaxy?
How life began, and whether it exists elsewhere, is a fascinating question which we still cannot answer. Of the eight planets in our Solar System, only one - Earth - has life as far as we know. But there are 400 million other suns in our galaxy, and billions of galaxies in the universe - so the chances are high that life exists elsewhere, and that intelligence and civilisation will have arisen more than once.
Since 1995, more than 350 planets have been discovered orbiting other stars. Known as exoplanets, they vary greatly in size and composition.
At COSMOS magazine, we thought it would be a cool way to celebrate National Science Week in Australia - and the International Year of Astronomy - by sending a message to a potentially habitable planet outside the Solar System.
Thanks to the support of Australia's Department of Innovation, Industry, Science and Research, the CSIRO and NASA, and a bunch of other really helpful people, the text messages collected on this site will be transmitted to the closest Earth-like planet that might harbour life: Gliese 581d.
At the end of Science Week, NASA will transmit the messages to Gliese 581d using the Canberra Deep Space Communication Complex in Tidbinbilla.
Will we get an answer? No-one really knows. So why not send a message and find out?
Thanks for taking part in HELLO FROM EARTH. Come to the site to check the messages others have sent. And we'll keep you posted on developments. [/quote]

[u]Why Gliese 581d?[/u]
With at least two potentially habitable planets and the most Earth-like planet discovered so far, the Gliese 581 system is one of the best candidates for life outside our Solar System... more information.

[U]How will the messages be sent to Gliese 581d?[/U]
After the final message has been collected on Sunday 23 August 2009, all the messages will be collected and exported as a text file and sent to NASA's Jet Propulsion Laboratory in California, where it will be encoded into binary code, packaged and tested before transmission. This system of beeps and pauses (on and off radio signals) will be sent back to Australia to the NASA/CSIRO Canberra Deep Space Communication Complex at Tidbinbilla, near Canberra. Over the past 37 years, the 70-metre main antenna, known as Deep Space Station 43, has supported many missions exploring our Solar System and beyond, including keeping in touch with the Apollo astronauts, providing two-way radio contact with the Mars Exploration Rovers, and deep-space missions such as the twin Voyager spacecraft and NASA's New Horizons probe to Pluto and the Kuiper Belt. DSS43 will transmit the signal to Gliese 581d on 24 August 2009.
[U]When will the messages arrive?[/U]
The signal will reach the solar system of Gliese 581 (the parent star) around December 2029 give or take a few months. Despite travelling at the speed of light, the radio signal will need to cross 20.3 light-years 192 trillion km of interstellar space before reaching the planet. It sounds like a long way, but Gliese is one of the 100 closest stars to Earth, making it our best target for sending and hopefully receiving a message within our lifetimes. Any response will need to travel the same way back, so unless Gliesans have improved communication technologies, the soonest we could hope to receive an answer would be in 42 years around 2051.
[U]How far will the signal travel?[/U]
After it reaches Gliese 581, the signal will continue almost indefinitely into space, diminishing as it recedes. The signal will be strong enough for the message to be read by any intelligent life with the capacity to do so up to 100 light-years from Earth; its artificial nature should be detectable up to 10,000 light-years distant. Since Gliese is in the direction of the constellation Libra, near the galactic centre, the signal has a reasonable chance of reaching the solar syetms of other stars before it fades completely.
[U]What should I write?[/U]
If you were face-to-face with an alien what would you say? How can we create messages that can be understood by beings on other worlds? These kinds of questions are part of the scientific prerogative of SETI (the Search for Extraterrestrial Intelligence) Institute's program in interstellar message composition. As yet, there've been no incoming messages to answer. But if science fiction is anything to go by, it's probably a good idea not to include insults or your home address. Sending out these cosmic calls encourages us to think about "the big questions of existence," says Davies of SETI and the BEYOND: Centre for Fundamental Concepts in Science at Arizona State University in the USA. These include: "what is life?", "what is intelligence?" and "what is mankind's place and destiny in the universe?", he says. Check our Top Messages to see the best ideas so far.
[U]What's the chance that anyone's listening?[/U]
Sending one small signal into the vastness of space is a bit like yelling for help from the ocean floor. But that doesn't mean that such cosmic calls are doomed to failure. In 1961, astronomer Frank Drake formulated an equation that predicted the likelihood of detecting other intelligent civilisations in our galaxy. In 2007, Drake told NASA's Astrobiology Magazine that he estimates we'll eventually find existing intelligent life in "one in ten million stars."
[U]What would Gliesians need to receive the message?[/U]
The message is encoded in binary and sent at a radio frequency at a particular bandwidth. To receive the message, Gliesians would need a radio receiver, and to understand it, the ability to interpret its binary nature (binary language, the language used by computers, consists of a series of zeroes and ones or on-and-off settings in a pattern).
[U]
What happens if someone or something responds?[/U]
Anyone can send a message to aliens if they're listening, and are from a star very close by, aliens have already enjoyed TV and radio signals that form part of the general background radio noise of our planet. But if any aliens respond, Earth protocol steps in. Response to any non-human communication received from another planet needs to be coordinated by the SETI Post-Detection Taskgroup of the International Academy of Astronautics, chaired by Paul Davies. If anyone or anything calls back, the protocol asks for the discoverer to inform all relevant scientific bodies, such as the taskgroup, as well as the government of the country concerned, says Davies. "The protocol says nobody on Earth should attempt to reply until international consultations have taken place. To safeguard this, the sky coordinates of the transmitting planet should be kept secret."

So what did I send?

Never gonna let you down
Never gonna run around and desert you

Have fun. :350:
cool meme there glad you did that.
Ahh register!
Nevermind then
Let's hope they understand English.

Thanks for the dumb rating, how about you contribute to the thread now.
Time to make future people believe I'm their god.

i didn't rate you dumb.
you started out the thread with a meme. the thread is already worthless. why would you do that.
I'm sending those little green dudes a haiku.
Here's what I said:
[quote]Dear Space Aliens:
Please don't annihilate our planet.
Thanks,

I registered and told them our galactic cooardinates, as well as the many natural resources that we would be more than happy for them to come and take.

Stop trolling and start contributing please. :sigh:

I was about to send a great message,
but the thread I leaned about this had a meme
[/quote]
Done.
[quote]Fuck you space[/quote]
fuck space
Reason why you posted that meme instead of another?
ok let me show you what i sent

no just kidding i am a step above the op
[QUOTE=Performual;16660809]Reason why you posted that meme instead of another?[/QUOTE]
In my opinion it's one of the most classic memes.

I'll do it later :D
I sent as many digits of e as I could.

If I can send another message, I will give our approximate distances from major stars so that our position can be triangulated.

You're threadshitting, and I already told you to get out if you can't contribute.
[QUOTE=VladimirPutin;16661186]You're threadshitting, and I already told you to get out if you can't contribute.[/QUOTE]
i contributed something of equal quality to what you contributed. maybe you should out of your own thread with me, and leave the thread making to big boys.
[QUOTE=Aurora93;16661028]So there's a half-a-gigabyte of worthless messages[/QUOTE]
That's almost 500kilobytes, not megabytes.
Because aliens are really going to understand binary..
Well I guess they wouldn't understand English either.
Hey guyse i can use memes lololol
[QUOTE=CadetBailey;16661199]i contributed something of equal quality to what you contributed. maybe you should out of your own thread with me, and leave the thread making to big boys.[/QUOTE]
I see you're still at it, insinuating all memes are of a low quality.
Sorry if you don't like getting rick rolled or something...
[quote]i can haz over 9000 mudkip memes lol cocks[/quote]
sent that just now i think it is a pretty funny message, see if you can spot the memes in it (memes make things funny)

I don't understand what you're getting at.
"The signal will reach the solar system of Gliese 581 (the parent star) around December [b]2029[/b] give or take a few months."
I don't think I'll be alive by then. That's 20 years from now.
[QUOTE=Evil_Toaster;16661318]I don't understand what you're getting at.[/QUOTE]
His inferior mind thinks I used a meme to sound funny.
I'm merely sharing some internet culture with possibly another civilization.
