A new study involving long-term monitoring of Alpha Centauri by NASA’s Chandra X-ray Observatory indicates that any planets orbiting the two brightest stars are likely not being pummeled by large amounts of X-ray radiation from their host stars. This is important for the viability of life in the nearest star system outside the Solar System. Chandra data from May 2nd, 2017 are seen in the pull-out, which is shown in context of a visible-light image taken from the ground of the Alpha Centauri system and its surroundings. Alpha Centauri is a triple star system located just over four light years, or about 25 trillion miles, from Earth. While this is a large distance in terrestrial terms, it is three times closer than the next nearest Sun-like star. Credits: Optical: Zdenek Bardon; X-ray: NASA/CXC/Univ. of Colorado/T. Ayres et al.

Chandra Scouts Nearest Star System for Possible Hazards

Chandra Scouts Nearest Star System for Possible Hazards In humanity’s search for life outside our Solar System, one of the best places scientists have considered is Alpha Centauri, a system containing the three nearest stars beyond our Sun. A new study that has involved monitoring of Alpha Centauri for more…

Nanocrafts to the nearest star system 4.37 Light-Years away Alpha Centauri

Nanocrafts to the nearest star system 4.37 Light-Years away Alpha Centauri. “Breakthrough Starshot“, “We came to the conclusion it can be done: interstellar travel,” Mr. Milner said. Announcing the project. Ground-based light beams to push the space probes. Ultra-light nanocrafts, attached to lightsails. To speeds of up to 100 million…
