The Search for Alien Artifacts

The Search for Extraterrestrial Artifacts

     The first workshop of the new German SETI initiative recently convened in the southern town of Freiburg, with experts in fields ranging from social science to satellite imaging on hand to discuss how to advance the search for extraterrestrial intelligent life.

Michael Schetsche from the University of Freiburg started things off with a talk on the possible consequences of first contact with an extraterrestrial species, and how we might prepare for such an encounter. A symposium held at the Library of Congress in Washington D.C. three years ago had a similar theme, but Schetsche’s talk focused more on contact with artificial intelligence or machine-based life.

Other talks had to do with SETA, the search for extraterrestrial artifacts, which will be one subject of future research by the German research network. Hakan Kayal from the University of Würzburg outlined today’s technical state of the art in detecting and identifying objects in space ….

Unusual structures in Crater Paracelsus C

Abstract

     The authors present an analysis of Apollo 15 and Lunar Reconnaissance Orbiter images of two unusual features in the crater Paracelsus C on the far side of the moon. At first glance these structures appear to be walls or towers on the lunar surface. By combining multiple images, we show the larger feature, oriented in a northeast/southwest direction, is not simply a wall but two walls on either side of a narrow valley or “passageway”. Using single image shape from shading and 3D terrain visualization we show in a

computer-generated perspective view looking northeast that the southwest end appears to be the entrance to the passageway. A reverse angle view looking southwest shows the passageway ending at a rise of terrain at the other end, possibly leading underground. The terrain surrounding the two structures is not flat but appears “excavated” by some unknown mechanism, natural or artificial. It is shown that these objects are visually different from the lunar background because their underlying structure is different.

Introduction

The search for extra-terrestrial intelligence (SETI) began in the 1960s with radio-telescopes and has, to date, produced no positive evidence of its existence. During these early years of SETI, Sagan [1] spoke about the possibility of extraterrestrial visitation, “It is not out of the question that artifacts of these visits still exist, or even that some kind of base is maintained
(possibly automatically) within the solar system to provide continuity for successive expeditions. Because of weathering and the possibility of detection and interference by the inhabitants of the Earth, it would be preferable not to erect such a base on the Earth’s surface. The Moon seems one reasonable alternative. Forthcoming high resolution photographic reconnaissance of the Moon from space vehicles – particularly of the back side – might bear these possibilities in mind.”

Alien Bases on the Moon? Nope.

I’ve been getting emails about these “structures” on the moon.

As you can see, the image is courtesy of NASA and Google Earth software. It comes from the second link noted below.

Sorry, folks, these are not artificial structures. There is no alien moon base.

This discussion from the Discover Magazine blog goes through what they are and why, with lots of illustrations. They digital imaging artifacts (i.e., the objects are created are residual effects from the camera, light, imaging process, etc.).

As good as that link is, this one is even better (it’s referenced within the first one). It takes you step-by-step as to how these images happened. It even has motion gifs illustrating how the are recreated and manipulated. Really cool stuff.
