A new study on the search for extraterrestrial intelligence (SETI) has proposed the best places to search for a signal from alien intelligences, suggesting it could significantly improve our chances ...

What new methods can be developed in the search for extraterrestrial intelligence (SETI)? This is what a recent white paper submitted to the 2025 NASA Decadal Astrobiology Research and Exploration ...

A new study suggests a novel approach in the long-running scientific endeavor to find intelligent life beyond Earth. Instead of casting a wide, speculative net across the cosmos, researchers from Penn ...

As humans began to explore outer space in the latter half of the 20th century, radio waves proved a powerful tool. Scientists could send out radio waves to communicate with satellites, rockets and ...

For decades, astronomers have searched for signs of extraterrestrial intelligence using radio telescopes and optical instruments, scanning the skies for artificial signals. Now, researchers are taking ...

Looking ahead: Expanded search strategies, improved computational power, and formal academic training are reshaping SETI into a mature scientific discipline. The timing is not accidental. SETI has ...

Earth may already be broadcasting its presence to alien civilizations without realizing it. A new study shows that our deep-space transmissions, especially those aimed at Mars and interplanetary ...

In a new study, researchers from Penn State and NASA’s Jet Propulsion Laboratory analyzed human deep space communications and found that human transmissions are frequently directed toward our own ...

In the third week of August 1977, Ohio State University astronomer Jerry Ehrman was going over a computer printout of signals collected a few days earlier from his university’s “Big Ear” radio ...

For decades, conversations about UFOs—now often referred to as unidentified anomalous phenomena (UAP)—have occupied an unusual place in public life. Many people are curious about the possibility of ...
