Although previous lunar observations have identified hundreds of possible entrances to lava tubes, these are the first to find them in a polar region, according to SETI
Another daunting issue facing SETI
efforts is the vast range of radio frequencies that hypothetical aliens could choose for their beacon: any of about 10 billion channels, if their beacon broadcast is a highly efficient signal 1 Hz wide.
Boyajian, the Breakthrough Listen project and the SETI
scientists will also be using the Green Bank radio telescope to stare at the dimming star over the next couple of months.
Book IV in the SETI
series should see a completion date by the end of 2015.
The idea is called active SETI
and, according to Vakoch, would involve the beaming of messages via radar and perhaps eventually lasers.
Located in a remote area in the shadow of Lassen Peak, east of Redding, California, it began initial operations in 2007, according to the SETI
In the past, failed SETI
searches have fueled further efforts.
Universities and research centers, such as the SETI
signal," no possible ETI signal has ever been heard, verified, and confirmed ever since Drake began the first search for SETI
signals some 48 years ago.
, the acronym for the search for extraterrestrial intelligence, is science's effort to detect evidence of intelligent life beyond the Earth by looking for signatures of its technology.
Nothing like this has ever been seen," says Mark Showalter, an astronomer at the SETI
Institute in California.
Los recursos economicos con los que puede contar una iniciativa de SETI
son escasos en el mejor de los casos, y la mayor parte del tiempo, inexistentes, debido a que es aun un area polemica de la investigacion cientifica.
