his image of the sky around the bright star Alpha Centauri A
B also shows the much fainter
red dwarf star, Proxima Centauri, the closest star to the Solar System. The picture was
created from
pictures forming part of the Digitized Sky Survey 2. The blue halo aroun
d Alpha Centauri AB is an
artifact of the photographic process, the star is really pale yellow in co
lour like the Sun.
