The search for extraterrestrial intelligence (ETI) has long been a topic of fascination. However, a new study available on the arXiv preprint server introduces a compelling idea about how we might ...

Black holes can release enormous energy through hot disks, surrounding plasma and powerful jets, enough to support a ...

For decades, science fiction writers have tried their best to prepare us for eventual contact with aliens. Their efforts are dominated by several recurrent tropes. There's the invasion by a warlike ...

Most alien-signal searches listen to a narrow part of the radio spectrum, but astronomers are now testing higher frequencies that have barely been explored. A first search using archived ALMA ...

Searching for extraterrestrial intelligence has so far primarily meant focusing on one particular type of signal—and that ...

Hollywood makes initiating alien contact seem much easier than it has proven to be. In E.T. the Extraterrestrial, E.T. got stranded on earth when his alien compadres abandoned their botany mission. In ...

For decades, SETI researchers have focused on finding narrow-band radio signals that might stand out from the natural universe. But what if an advanced civilization that wanted to communicate would ...

Astronomers may have been listening for alien civilizations in only a small slice of the radio spectrum while overlooking a largely unexplored range of higher frequencies. Using archived data from the ...

In 1961, Dr Frank Drake proposed a probabilistic, though highly speculative, equation to determine the number of intelligent ...

Elon Musk’s plans for the future of SpaceX, and humanity, are rooted in an idea conceived in the 1960s when astronomers began to pick up mysterious, unknown radio sources in the cosmos. Soviet ...

They’re hole-ar powered. If super-advanced alien civilizations exist, they would surely require insane amounts of energy to ...

For decades, radio SETI searches have focused on one important question: if another technological civilization is trying to contact us, how would they send that message? For Dr. Zuckerman, the ...
