Many stars in our galaxy exist in pairs. Now scientists are finding clues that our Sun may once have had a companion of its own. The question is, where did it go?

It appears to move because it’s so close to the solar system. Only the three-star Alpha Centauri star system, which is 4.1 light-years distant, is closer. In 2016, astronomers found a planet ...

Astronomers measure a star’s brightness using the apparent magnitude system, where lower values indicate brighter stars.

The project hopes to propel roughly 1,000 tiny "StarChip" spacecraft toward Alpha Centauri, the second-closest star system to Earth, at 20% of light-speed (about 134 million mph). Each "chip ...

Alpha Centauri, the closest star system to Earth, is home to three stars, one of which is so tantalizingly similar to our sun that many experts speculate that its solar system might contain ...

If you want to go as far as our nearest star, Alpha Centauri, you’ll need to travel even faster. Even going at the speed of light, it would take four years to get there. Thus, a probe intending ...
