Abstract: Welding defects recognition based on arc sound signals remains a significant challenge in robot arc welding. Existing deep learning methods mainly focus on classifying penetration states ...

If a genuine extraterrestrial signal ever arrives, the hard part may not be detecting it, but understanding what it means. That is the central idea behind a NASA History Series book that explores how ...

Advanced aliens could be chatting with each other using light flashes in plain sight, similar to how fireflies communicate, according to a new study that could lead to new approaches in finding ...

A new paper posits that advanced alien civilizations may communicate through subtle flashes, like fireflies do on Earth. The thought experiment suggests that we need to avoid human biases in our ...

3I/ATLAS, the interstellar comet that sparked debate among scientists due to speculation about its possible alien origins, is now on its way to the outer limits of the solar system. Despite the ...

In July, researchers using the NASA-funded Asteroid Terrestrial-impact Last Alert System survey telescope in Chile made an exceedingly rare discovery: a mysterious object passing through the solar ...

The first alien signal humanity detects might not come from a thriving civilization, but rather from one in decline, possibly sending a cry for help. That’s the central idea behind a new paper by ...

A year-long SETI Institute investigation into a flickering pulsar has revealed how radio waves warp as they travel through deep space, offering a powerful new tool for distinguishing natural cosmic ...

Chinese scientists' claims that their "Sky Eye" telescope could have picked up signals from intelligent aliens have been met with skepticism by an American colleague. ‘We are looking at a massive ...

Astronomers at South Africa's MeerKAT radio telescope have detected the first radio waves coming from the interstellar comet 3I/ATLAS. But while this sounds suspiciously like alien activity, it is ...

When we imagine contact with extraterrestrial intelligence, we tend to picture messages: radio signals, mathematical codes, or perhaps a universal language waiting to be discovered. But what if alien ...
