Why we keep scanning the skies for signs of alien intelligence

In just something less than one hour, an important decision was made back in 2nd of December. Avi Loeb and Yuri Milner gathered together to discuss the bizarre features of the interstellar object called “Oumuamua”.

After 10 hours of observations the telescope, there was no evidence found that actually this interstellar object is a work of an alien civilization. It looks just like a dark, skyscraper-sized lump of carbon – ice and dust that simply somehow tumbled in our solar system from… Well, it is isn’t very clear from where, but it is somewhere beyond. One’s for sure though: there are hunts for life somewhere else, that are driven by private money, not national space agencies and governments.

The US Department of Defense has recently confirmed that back in 2007, it started running an investigation for unidentified flying (UFO) objects, but they stopped funding this program 5 years later. One of the officials who were running the Advanced Aerospace Threat Identification Program gave his resignation and later joined private venture in order to continue with the work he already started.

When Monica Grady oversaw the meteorite collection in the History Museum based in London, she received a lot of letters about alien structures that were spotted over Britain. Even if most of the letters ended up in the trash bin, one of them was a bit more intriguing. It was from a man that photographed that he later described as an alien vessel that could be seen at the bottom of his garden. He said thet no-one else noticed this, but he is pretty sure that it was directly responsible for the road aged, cot death and measles.

Grady, who is a professor of planetary science, said: “For me, it’s the difference between astrology and astronomy. We don’t have any credible sightings that are more likely to be an alien spacecraft than not.”

“We are not expecting to get to the bottom of Enceladus’s ocean and find a whole load of gnomes smelting metal”, Grady added, of course – referring to the tantalizing subterranean water on the moon of Saturn.

Many discoveries so far are suggesting that some kind of life should actually exist somewhere in the universe. Even some scientists from NASA’s Kepler missions believe that almost every star out there has at least one orbiting planet. In this context, Siemion said: “Everything necessary for life to arise and thrive on this planet exists in abundance throughout the universe.”

“If the processes that got life going on Earth are universal, then some form of life should have got going.”

“The reason people are so incredibly interested and excited is that it’s such a profound human question. We have a basic desire to know what is beyond, what is out there. What we have done so far is very minimal. We have far more work to do,” Siemion explained.
