The Center for High Angular Resolution Astronomy (CHARA) Array is a six-element interferometer
with baselines ranging from 34 to 331 m. Three new beam combiners are entering operation:
MYSTIC is a 6-telescope combiner for K-band; SPICA is a 6-telescope combiner for the
visible R-band; and SILMARIL is a 3-telescope combiner for high sensitivity in H and
K-bands. A seventh, portable telescope will use fiber optics for beam transport and
will increase the baselines to 1 km. Observing time is available through a program
funded by NSF. The programs are solicited and peer-reviewed by NSF's National Optical-Infrared
Astronomy Research Laboratory. The open community access has significantly expanded
the range of astronomical investigations of stars and their environments. Here we
summarize the scientific work and the on-going technical advances of the CHARA Array.
