Extraterrestrial

Researchers have developed a new technique to better detect extraterrestrial radio signals by weeding out the interference caused by Earth-based devices. It’s hoped that the technique will lead to the first evidence of alien life.

A new discovery has boosted the chances of life soon being found on another world. NASA has announced the detection of phosphorus, the rarest element that’s essential to life, in the oceans of Saturn’s moon Enceladus.

A new study suggests that if any alien civilizations are turning their radio telescopes toward Earth, they may be able to not only detect our mobile phone signals, but could deduce a lot about our planet and even produce crude maps of it.

The search for extraterrestrial civilizations gets a major boost as SETI joins forces with the Very Large Array (VLA) that combines the giant radio telescope with a new processing system to increase the search's effectiveness by a factor of 1,000.

Millions of planets have sides permanently bathed in the light of their star, and sides always cloaked in darkness. Between these two sides lies the "terminator zone," a logical place to search for extraterrestrial life, says a new study.

The chances are incredibly small that Earth is the only planet with life. A new AI system has scoured millions of radio signals from space to identify any with potential artificial origins – and discovered eight signals that look intriguingly alien.

A new instrument integrated into the Southern Hemisphere’s largest radio telescope has given it the capabilities to detect technosignatures of extraterrestrial intelligence, significantly widening the net for scientists in search of alien life.

Humans might not be the first lifeforms to face self-induced climate change. A new model suggests Mars was once habitable enough to support microbes, and they may have wiped themselves out by causing irreparable damage to the Red Planet’s atmosphere.

The James Webb Space Telescope has clearly detected carbon dioxide in the atmosphere of an exoplanet for the first time. The find marks a milestone for the telescope’s goal of analyzing the air of distant planets to aid the search for alien life.

The discovery of extraterrestrial life is most likely to come from tiny fossils on Mars. To aid that search, scientists have developed a portable device called the Biofinder that can highlight organic residue in fossils tens of millions of years old.

Scientists debate whether or not there’s life on Venus. A new Cambridge study has analyzed the Venusian atmosphere and found no sign of the chemical fingerprints microbes would be expected to produce – but it doesn’t rule out life on similar planets.

UFOs have rarely been taken seriously by the scientific community. But following a recent hearing by the United States Congress into “unidentified aerial phenomena” (UAPs), NASA has now announced that it’s commissioning a team to investigate the mystery.
