Scientists at the SETI Institute recently 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 ...

NASA and the European Space Agency announced Monday that the James Webb Space Telescope has produced the first mid-infrared chemical fingerprint ever obtained from an interstellar object, detecting ...

If the new Vera C. Rubin Observatory had begun its science validation phase a few weeks earlier, it might have been up and running in time to discover 3I/ATLAS first. When you purchase through links ...

We already knew interstellar comet 3I/ATLAS came from somewhere far beyond our solar system. Now scientists have more information on how alien that somewhere really is — a corner of the universe ...

Interstellar comet 3I/ATLAS is now on its way out of our solar system, never to return. The comet was only the third-ever detected object to originate from outside our solar system. Traveling at high ...

An assessment published this week on the isotopic composition of interstellar comet 3I/ATLAS suggests an intriguing possibility: The comet may be between 10 and 12 billion years old, making it roughly ...

The interstellar comet 3I/ATLAS contains water and carbon molecules at levels never before seen in our solar system. This suggests that it formed around an alien star radically different from and much ...

Comet 3I/Atlas is now heading out of the solar system and into interstellar space, but scientists are still analyzing the data it left behind as it passed through our cosmic neighborhood. A new study, ...

The interstellar comet 3I/ATLAS was confirmed in July 2025 as the third known object to visit our solar system from interstellar space. Despite conspiracy theories, scientists say 3I/ATLAS shows all ...

The interstellar comet 3I/ATLAS was the third object ever discovered in our solar system that originated from another star system. Despite a viral conspiracy theory, NASA officials have repeatedly ...
