A new study involving monitoring of nearest stars beyond our Sun revealed that one of them might be friendlier to life than the Sun in terms of X-ray radiation.

The United States space agency NASA said on Wednesday in a news release that any planets orbiting the two brightest stars in the Alpha Centaur system were likely not being pummeled by large amounts of X-ray radiation from their host stars.

Alpha Centauri is a triple star system located just over four light years, or about 40 trillion kilometers, from the Earth.

"Because it is relatively close, the Alpha Centauri system is seen by many as the best candidate to explore for signs of life," said Tom Ayres with the University of Colorado Boulder.
