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

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?

Getting a spacecraft to another star is a monumental challenge ... "wings" that would allow them to ride a beam of light to Alpha Centauri. However, for practical purposes, a probe that small ...

ST. PETERSBURG, September 24. /ITAR-TASS/. St. Petersburg astronomers have spotted one more planet circling a star in the Alpha Centauri system just 4.36 light-years away from the Solar System.

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 ...

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 ...
