Aliens

Are aliens real? While there is no current evidence for extraterrestrial life anywhere in the universe, scientists are still optimistic.

Alien life could thrive in terminator zones, the edges between the light and dark sides of planets that are tidally locked with their host stars.

A draft paper by a Harvard scientist and the head of the Pentagon’s UFO office has raised the idea an alien mothership could be in the solar system, sending out tiny probes dubbed "dandelion seeds" to explore the planets within.

Simulations show that collisions between moons and planets may be a regular danger for possible extraterrestrial life.

The U.S. military shot down three unidentified objects in a single weekend. Why are America's skies so filled with UFOs all of a sudden?

The U.S. shot down a UFO over Lake Huron on Sunday, while Prime Minister Justin Trudeau said the U.S. shot down an unidentified flying object over the Yukon, Canada at his request.

Eight signals from far-off stars probably aren't aliens, but the machine learning method that found them holds promise in the search for real extraterrestrials.

Through a phenomenon known as gravitational lensing, aliens could be transmitting signals using the sun, but a quick scan for such signals has turned up nothing.

Early life made an inhospitable Earth more habitable, and aliens could be doing the same thing on their worlds, new research proposes.

Nearly half of all new UFO cases opened in 2022 cannot be explained, Pentagon officials wrote.
