After you've spent more than 20 years hunting for an alien signal, you think you'd be celebrating if you noticed a mysterious pulse suddenly rising up on your computer readouts. A regular pulse, amid the random clatter of the cosmos, suggests that someone very smart at the other end is sending a message.
But when Ragbir Bhathal, an astrophysicist at the University of Western Sydney, who teaches the only university-based course on SETI (search for extraterrestrial intelligence) in Australia, detected the suspicious signal on a clear night last December, he knew better than to crack open the special bottle of champagne he has tucked away for the history-making occasion.

The Drake equation

The Drake equation (also sometimes called the "Green Bank equation", the "Green Bank Formula) is a famous result in the fields of exobiology and the search for extraterrestrial intelligence (SETI). This equation was devised by Dr. Frank Drake (now Professor Emeritus of Astronomy and Astrophysics at the University of California, Santa Cruz) in 1960, in an attempt to estimate the number of extraterrestrial civilisations in our galaxy with which we might come in contact. The main purpose of the equation is to allow scientists to quantify the uncertainty of the factors which determine the number of such extraterrestrial civilisations.

For nearly 50 years, the Search for Extraterrestrial Intelligence (SETI) has scanned the heavens with radio telescopes for signs of alien technology. At the same time, scientists have painstakingly crafted messages to send in reply. When NASA launched its Voyager missions in 1977, for example, both spacecraft carried audio recordings depicting the diversity of life and culture on Earth.
But never have those messages truly represented all of humanity. On 15 May that will change as the SETI Institute launches a project to collect messages from people around the world.

As many as 38,000 alien civilisations could exist in our galaxy, all with the potential to make contact with Earth, scientists have claimed.
Scottish researchers have predicted there are likely to be at least 361 inhabited planets in the Milky Way, but say there could be more than 100 times that number.
And they say humans are likely to start detecting alien civilisations within the next few hundred years.

The desire to contact intelligent life on other planets is much older than the UFO craze and the SETI movement. Several 19th century scientists contemplated how we might communicate with possible Martians and Venusians.
These early proposals - which predate by 150 years the first extraterrestrial message that was sent in 1974 - were based on visual signals, as the invention of radio was still decades away.
In fact, as history shows, ideas for interplanetary communication have largely been driven by whatever the current technology allowed - be it lamps, radios or lasers.
