Even at this early stage in our space faring age, humanity has already begun sending probes that will eventually reach other solar systems, even if that was not their original intention. Five robotic explorers – Pioneer 10 and 11, Voyager 1 and 2, and New Horizons – are all on escape velocities out of the… read more

A meteorite shows evidence that an ancient crash on the moon 3.5 billion years ago was so powerful, it turned the surface molten. Read Full Story read more

Our search for technosignatures – clear signs of advanced civilizations beyond Earth – takes many forms. Many are driven by the famous Drake equation, which attempts to estimate how many technological civilizations there are in the Milky Way. However, there’s a big fat question mark at the end of that equation in the form of… read more

In a recent NASA-supported study, researchers assessed Titan's resource base and how it could be leveraged for ISRU. Compared with other locations under study (the Moon, Mars, etc.), they concluded that there is unrivaled potential for human exploration and settlement. Read Full Story read more

Scientists at the SETI Institute searched for technological signals from 3I/ATLAS, the third interstellar object observed in our Solar System. Using the Allen Telescope Array (ATA) at the Hat Creek Radio Observatory in Northern California, the team scanned a wide range of radio frequencies for signs of extraterrestrial technology and found none, as expected based on other… read more

An international committee of experts says it has updated its rules for evaluating and revealing the detection of extraterrestrial intelligence. The revisions to the decades-old Declaration of Principles, created and maintained by the International Academy of Astronautics' SETI Committee, come just days before the release of "Disclosure Day," a movie about alien visitation directed by… read more

Scientists failed to find radio signals emanating from the interstellar comet 3I/ATLAS, further bolstering its status as a natural object, not one made by aliens. Read Full Story read more
