Ufology claims that many unidentified flying objects (UFOs) would be spaceships from alien species, and ancient astronauts hypothesis claim that aliens would have visited Earth in antiquity and prehistoric times but people would have failed to understand it by then. [148]
Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.. Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain an environment hospitable to life. [1]
New research suggests that if there are aliens out there living on “Super-Earth’ planets, they may be stuck there. The findings submitted to the International Journal of Astrobiology propose ...
Could you survive an alien invasion? Well, if you believe the data collected in a new study, Georgians have a good shot to beat the invaders. New study says Georgians have a good chance
Nucleic acids may not be the only biomolecules in the universe capable of coding for life processes. [1]Astrobiology (also xenology or exobiology) is a scientific field within the life and environmental sciences that studies the origins, early evolution, distribution, and future of life in the universe by investigating its deterministic conditions and contingent events.

Humanity's first contact with aliens could be a breezy 24 years away. We sent a signal to an Earth-like planet that may host live – and we sent them a mixtape. Humans just tried to contact ...
However, the experience on earth shows that species moved from one continent to another may be able to out compete the native life adapted to that continent. [9] Additionally, evolutionary processes on Earth might have developed biological pathways different from extraterrestrial organisms, and so may be able to outcompete it.
