We almost always imagine human – ET encounters in which the ETI, being highly advanced in science and technology, come to  the earth either as marauding invaders spelling doom for humankind or as benign benefactors solving our problems and guiding us to a better future. Even when we create an ETI that is in distress, we usually imagine him/her to be retaining his/her extraordinary powers to be able to command the situation as a superior being (Spielberg's ET, for example).

We are told that we separated from the other animals in the Garden of Eden. By partaking of the fruit of knowledge we came to know good and evil. At that point we lost our innocence and parted from our simpler brethren, and we can never return to our once idyllic state. We went from living in harmony with nature and the other animals to a position of separation. A separation that some have interpreted as giving us dominance over all creation. This perceived dominance has led to our hunting animals virtually at will, putting them into zoos, and making them amuse us as part of circus acts. We destroy their habitats to make room for our cities and roads and we accord them no “inalienable rights”. We may, as current developments seem to indicate, pay dearly for this. The biosphere seems to be unraveling as species disappear at an alarming rate and, as much as we try to distance ourselves from the other animals, we are a part of that biosphere. But dominance is the role we have assigned ourselves and we must live with the consequences.

Development work at the Boquete Observatory has always been a high priority.  It is the principal activity during the rainy season when good observing nights are few in number. When gains have been made the efforts always began with a broadened viewpoint.   During the past year or so, and in close collaboration with Bruce Howard (Owl Observatory in Michigan), our two observatories have made significant improvements in methods and practices for SETI searches.

SETI astronomers sometimes pick up strange signals. They don’t look like the regular type of radio transmissions we get from stars and other natural things in space. When this happens, they pay attention. These signals could be transmissions from extraterrestrials.

METI scientists need to defend their message-sending to possible new neighbors on planets elsewhere in the Milky Way metropolis. Fearing that hostile aliens will receive these messages and order their armies to conquer and colonize Earth, METI critics such as Stephen Hawking raise a challenging ethical question. How might we connect this question with a dozen other astroethical questions formulated to deal with space exploration within our solar ghetto? (1) does planetary protection require protection of off-Earth ecospheres? (2) do extraterrestrial microbial life and of off-Earth ecosystems have intrinsic value? (3) should space scientists invoke the Precautionary Principle? (4) should earthlings clean up space junk? (5) what should we do about satellite surveillance? (6) should we weaponize space?  (7) how should we adjudicate the competition between scientific research and economic interests, including space tourism? (8) should we terraform Mars? (9) should we colonize Mars? (10) how can we protect Earth from extraterrestrial threats such as solar flares, asteroid collisions, and gamma bursts? (11) does astroethics require a single planetary community of moral deliberation? (12) should we stretch the common good into a cosmic commons? Can we stretch these existing ethical issues drawn from within our immediate solar ghetto to include the entire Milky Way metropolis, including our first encounter with exoplanetary civilizations?

We haven’t found extraterrestrial intelligence yet, but that hasn’t stopped us from wondering what they would be like. Science fiction has plenty of answers, with just about anything you could imagine meeting up with the crew of the USS Enterprise at some point. But there’s one overwhelming trend in sci-fi. Aliens look humanoid. That’s understandable for some reasons. It’s much easier to dress up an actor in a rubber suit or put green make-up on his face than construct an animatronic fifty-legged giant insectoid with five heads. Sci-fi shows make extraterrestrials not too different from us for economic reasons. But they could be on to something more realistic than they know. Extraterrestrials will almost certainly look different from humans, but they will probably not be as wildly different as some fantasy writers expect.

Our search for extraterrestrial intelligence employs as many methodologies as possible. It makes sense. The more you look, the greater the chances of discovering ETI. There’s another issue. We are not really sure of how extraterrestrials would communicate with us. Would they use radio waves, lasers, or something more exotic? Perhaps the universe is awash in extraterrestrial signals that we cannot even receive. SETI and METI practitioners spend a lot of time wondering how a message would be encoded in terms of language and content. It’s also important to consider the medium of transmission.

An interesting question that often arises in relation to the search for extraterrestrial intelligence (SETI) is: What impact would contact actually have on humans? Several years ago, in an attempt to quantify the importance of candidate SETI signals we receive, astronomers Ivan Almar and Jill Tarter proposed a scale to measure social consequences of contact, based on the Torino Scale used to quantify the consequences of an asteroid approach to Earth by relating the likelihood of impact with potential damage the asteroid might cause.

Social media and news outlets the past few days have been abuzz with the prospects of a strong signal apparently coming from the star unromantically known at HD 164595, which is about 94 light years from Earth. Reading news reports, one would think that the signal was intercepted last week, but actually it was picked up over a year ago in May of 2015.

I’ve often thought it interesting that when SETI scientists imagine extraterrestrial civilizations, they usually think in terms of unified worlds that have one civilization. The image is very much unlike our world, in which we have multiple civilizations that are fractured and in conflict with other societies. The Brexit event of the past couple of days is a good example of just how fractured our world is as well as representing some solid data not in support of the idea that humans are becoming increasingly unified.
