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.
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".
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.
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.
Astronomers searching for radio signals that could be signs of extraterrestrial life have just gained access to South Africa's MeerKAT telescope.
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.
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.
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.
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.
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
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.
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.
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.
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.
Technosignatures are what we humans would recognize as signs of technologically-advanced activity of an extraterrestrial intelligence.
