Sagan Day Celebrations – Day VI

We Are at the Prow of the Whole – By Rui Borges

We find ourselves, in this present time, in this present space, sharing a common opportunity to consciously share the wonders of this journey through the Universe. We are, at the same time, those with the power to generate questions and to seek the answers. We are the whole on a quest for its own reason. The Universe has, in its infinite sequence of events, generated its own awareness and we, as life, as percipient life, are at the threshold of the Incredible. Read Full Essay

 

50 Years of SETI: One Cup of the Cosmic Ocean – By Jill Tarter, SETI Institute

Frank Drake conducted the first radio search for extraterrestrial intelligence fifty years ago; radio and optical search programs have been ongoing ever since. Many people think that means that we’ve searched exhaustively and should now draw pessimistic conclusions from our lack of success thus far. Carl Sagan knew better. His imagery of the vast cosmic ocean puts our efforts into context. We have barely begun to search! Read Full Essay

His words — our words — as beacons for the future.

Theme: “The surface of the Earth is the shore of the cosmic ocean. On this shore, we’ve learned most of what we know. Recently, we’ve waded a little way out, maybe ankle-deep, and the water seems inviting. Some part of our being knows this is where we came from. We long to return, and we can, because the cosmos is also within us. We’re made of star stuff. We are a way for the cosmos to know itself.” – Carl Sagan, Cosmos, 1980 In honor of Carl Sagan’s birthday on November 9th, we invite you to pause and reflect on the imagery that he created for us in his allegory of the Shore of the Cosmic Ocean. We invite you to communicate your thoughts and ideas, your reflections on the past and your visions for the future. We want the written expressions of what you see as you stand on that shore. How did you arrive there with your individual perspective? Where will we go from here? What drives us toward those distant shores? What embodies the spirit of exploration? All ideas inspired by The Shore of the Cosmic Ocean are acceptable.

Classification of Interstellar Radio Messages

During the preparation and transmission of any interstellar radio messages (IRMs), some scientific and technological issues need to be addressed. The paper «Messaging to Extra-Terrestrial Intelligence» (METI) [1] lists nine of such issues. We propose to rank planned and already sent IRMs depending on how well three basic METI’s issues are resolved in them. These basic issues are the following: (1) choice of the target stars, (2) energy required per bit of the information, and (3) availability of a special digital or analog key to allow Aliens to decode our message, [2]. In order to rank IRMs, it is necessary to find out whether there are serious concerns regarding of how these three issues were addressed.
