Caption: This picture combines a view of the southern skies over the ESO
3.6-metre telescope at the
La Silla Observatory in Chile with images of the stars Proxima Centauri (lowe

star Alpha Centauri AB (lower-left) from the NASA/ESA Hubble Space Telescope.
Proxima Centauri is
the closest star to the Solar System and is orbited by the planet Proxima b,
which was discovered
using the HARPS instrument on the ESO 3.6-metre telescope.
