Humanity has already sent five spacecraft on trajectories that will eventually carry them beyond the Solar System, demonstrating that technologically advanced civilisations can launch interstellar ...

Our galaxy is full of strange worlds, but what would happen if we could bring some of them into our own Solar System? Moving exoplanets closer helps us imagine how different stars, atmospheres, and ...

Researchers tested whether they could detect unusual radio signals coming from an interstellar object passing through our ...

WASHINGTON :In a potential landmark discovery, scientists using the James Webb Space Telescope have obtained what they call the strongest signs yet of possible life beyond our solar system, detecting ...

WASHINGTON (WASHINGTON POST) - Some 70,000 years ago, when humans and Neanderthals shared the planet, an alien star streaked through the outer edges of our solar system and jostled its contents, ...

The most crowded alien planetary system found yet possesses five worlds all orbiting a star at least 12 times closer than Earth does the sun, researchers say. Investigators discovered these exoplanets ...

Despite their (potentially) impressive numbers, these interstellar objects remain extremely difficult to observe. The odds of one venturing within 10 astronomical units—10 times the distance from ...

A recent study has renewed discussion about whether advanced extraterrestrial civilisations could leave detectable technosignatures within our own Solar System, including in the asteroid belt. In the ...

Alien life may be hiding much closer to home than science fiction would have us believe, according to a particle physicist and dark matter researcher Dr Sarah Alam Malik, who argues that Saturn's ...
