The dream of interstellar travel is becoming increasingly real, and Alpha Centauri, the closest star system to Earth, is at ...

Alpha Centauri, the closest star system to Earth, has long intrigued astronomers searching for signs of habitability beyond ...

Alpha Centauri is about 4.4 light-years (roughly 25 trillion miles, or 40 trillion kilometers) from Earth and is home to three separate stars.

Alpha Centauri A and B have been observed with different methods, including spectrophotometry (emission at different wavelengths) and astrometry (position in the sky; motions).

"I think that we will reach the Alpha Centauri system, with small probes launching in the decade of the 2040s, and thus arriving in the 2060s," Eubanks said.

Our nearest stellar neighbor, Alpha Centauri, is moving towards us at a slow and steady pace. In about 3,000 years, the triple star system will be at its closest point to Earth, but new research ...

New research has indicated that, if Alpha Centauri ejects as much material as the solar system, then as many as one million space rocks larger than 328 feet (100 meters) wide could be lurking in ...

A laser-powered, AI-designed “potato” lightsail could send a probe to Alpha Centauri in just 20 years. Here’s how it could change space travel forever.

During six months in 2020 and 2021, 88000 exposures for Proxima Cen and 47000 exposures for Alpha Cen were obtained. No evidence was detected of light pulses or continuous laser emission in the ...

The Alpha Centauri system has been center stage in scientific discoveries recently, and is a focus across the breadth of the Breakthrough Initiatives. As the closest star and planetary system to our ...
