The 'potentially hostile alien threat' that has been at the centre of much debate among scientists will now be visible from Earth as the mystery object moves away from the Sun. You might be familiar with 3I/ATLAS, the extraterrestrial comet that has been bamboozling scientists ever since it was spotted hurtling through space in July.

Ars Technica: The Voyager Golden Record is perhaps the best known example of humans attempting to communicate with an alien species, spearheaded by the late Carl Sagan, among others. But what are the odds that, despite our best efforts, any aliens will ever be able to decipher our “message in a bottle”?

Humanity's age-old fascination with extraterrestrial life was reignited by the arrival of interstellar object 3I/ATLAS. While initial observations fueled speculation of alien technology, including unusual brightness and a lack of a comet tail,

Scientists have developed a new way to hunt for hidden signals of past life, and say it could assist in the search for extraterrestrial organisms on other planets.

A scientist says self replicating alien probes may already be hidden in the Solar System, possibly on the Moon, leaving detectable signs for future searches.

Researchers discovered that living horsetails act like natural distillation towers, producing bizarre oxygen isotope signatures more extreme than anything previously recorded on Earth—sometimes resembling meteorite water.

Rather than assuming that advanced civilisations are hiding from us, are transcendent beings we can't begin to understand, or have simply gone extinct, Corbet suggested that alien societies might plateau at modest technological levels and even grow bored with exploration.
