Planetary System Probed For Signs of Alien Technology

Some 100 light-years from the Solar System dwells the most mathematically perfect planetary system we've ever seen. The star at its center – a temperate orange dwarf called HD 110067 – is orbited by six exoplanets.

Alien Civilizations May Be Trapped on Their Home Worlds

Spanish professor argues that that water or other liquid-dwelling aliens, as well as civilizations on super-Earths, may actually be trapped on their planets due to "physical limitations".

New Theory Shows How Civilizations Can Spread Like Wildfire Through Space

With only one habitable planet (Earth) and one technologically advanced civilization (humanity) as examples, scientists are still confined to theorizing where other intelligent life forms could be.

Scientists Are Looking For Alien Signals From The Heart of The Milky Way

The Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS) project is designed to seek and amplify strangely pulsed radio emission from the galactic center that may be messages from extraterrestrial intelligences.

Search for alien life just got 1,000 times bigger

Astronomers searching for radio signals that could be signs of extraterrestrial life have just gained access to South Africa's MeerKAT telescope.

A Mysterious Signal from Proxima Centauri

The signal appears to emanate from the direction of our neighboring star and cannot yet be dismissed as Earth-based interference, raising the very faint prospect that it is a transmission from extraterrestrial intelligence.

Survey finds no detectable alien radio signals across 10 million stars

Australian astronomers surveyed a patch of sky around the constellation Vela known to include at least 10 million stars. They found no technosignatures – no sign of intelligent life.

Extraterrestrial Hunters to Expand Their Search

It looks as though Breakthrough Listen’s ( a non-profit organization dedicated to advancing space exploration ) search efforts could be expanded by a factor of more than 200.

Research sheds new light on intelligent life elsewhere

A recent UK study shows that there could be about 36 active communicating intelligent civilizations in our home Galaxy. This is an enormous advance over previous estimates which spanned from zero to billions.

The odds of life and intelligence emerging on other planets

According to a recent study, if planets with similar conditions and evolutionary time lines to Earth are common, then life should have little problem spontaneously emerging on other planets and the odds are 3:2

Study examines which galaxies are best for intelligent life

Giant elliptical galaxies are not as likely as disk-shaped galaxies, such as our own Milky Way, to be cradles of technological civilizations, according to a recent U.S. paper.

Weird "Vanishing Stars" Could Potentially Be Extraterrestrials

A comparative analysis of historical and contemporary astronomical data has resulted in the discovery of approximately 100 star-like objects that unexpectedly vanished. These strange occurrences are likely natural, but scientists say alien technology is a remote possibility.

SETI Released The Most Comprehensive Dataset On Alien Life Search

Breakthrough Listen is an astronomical program which surveys the universe in an attempt to track down alien life. Its data were recently offered to prestigious astrophysics journals, and the amount of information is quite impressive.

Future Telescopes could Detect Starships Powered by Black Hole

Recent U.S. study suggests how surveys using gamma telescopes could find evidence of spacecraft powered by tiny artificial black holes. The concept of a black hole-powered spacecraft was first introduced by science fiction author Arthur C. Clarke.

NASA's Technosignatures Report is Out

Technosignatures are what we humans would recognize as signs of technologically-advanced activity of an extraterrestrial intelligence.
