In 1995, a pair of scientists discovered a planet outside our solar system orbiting a solar-type star. Since that finding—which won the scientists a portion of the 2019 Nobel Prize in ...

In the vastMilky Way, billions of planets may harbor life, but new research presented at the EPSC-DPS2025 Joint Meeting suggests that alien civilizations capable of communication are likely rare. Led ...

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 ...

Complex, intelligent life in the galaxy appears vanishingly rare, with the nearest possible civilization perhaps 33,000 light-years distant. Yet despite the odds, scientists insist that continuing the ...

Technosignatures are theoretical signs of technologically advanced alien civilizations, but so far, none of those civilizations have phoned home. Researchers from the Search for ExtraTerrestrial ...

We’ve likely had at least one close encounter of the 3I kind before. Harvard scientist Avi Loeb claims that not only does 3I/ATLAS potentially have alien origins, but that this wouldn’t be the first ...

A new SETI methodology focuses on detecting the "spillover" from directed interstellar communications, mirroring how we communicate with our own spacecraft, rather than relying on broad, speculative ...

A new study presented at the 2025 EPSC/DPS Joint Meeting proposes that the rarity of specific geological and atmospheric conditions necessary for technologically advanced life significantly limits the ...
