Reaching Alpha Centauri within a single human lifetime has long sounded like science fiction, yet a new generation of nuclear ...

In the late 1950s, Project Orion proposed using controlled nuclear explosions to propel massive spacecraft at unprecedented speeds. From city-sized starships to a 44-year journey to Alpha Centauri, ...

Alpha Centauri, one of the two "Pointer Stars" that help stargazers find the Southern Cross in the Southern Hemisphere, may have a planet in orbit around it. If it does, the Webb Telescope will find ...

Interstellar asteroids visiting our solar system from parts unknown used to be the stuff of science fiction. But today, we know of at least two such bodies Oumuamua and 2I/Borisov respectively ...

In April last year, billionaire Yuri Milner announced the Breakthrough Starshot Initiative. He plans to invest 100 million US dollars in the development of an ultra-light light sail that can be ...

The appearance of the interstellar objects (ISOs) 'Oumuamua and Comet Borisov in 2017 and 2019, respectively, created a surge of interest. What were they? Where did they come from? Unfortunately, they ...

Astronomers have used NASA's James Webb Space Telescope to find strong evidence for a planet orbiting a star in the triple system closest to our own sun. At just 4 light-years away from Earth, the ...

Alpha Centauri A, on the other hand, is much more interesting from an Earth perspective. It's a G2V star similar to the Sun, which is a kind that we know can support a life-bearing planet because ...

Scientists may have found the first planet ever detected around our closest “solar twin,” a star called Alpha Centauri A, the same real-life star that was home to the fictional moon Pandora in James ...

A team of astronomers on Thursday provided the strongest evidence yet that a planet circles one of Alpha Centauri’s sunlike stars. The world is at the very edge of the region around the star where ...
