(Microvariability and Oscillations of Stars)
(observatory-satellite to look for stellar oscillations)
MOST (Microvariability and Oscillations of Stars)
is a Canadian satellite designed to detect minute variations
in the light of stars to study their seismology
which requires viewing stars for much longer periods
of time than can be afforded with telescopes such
as the Hubble Space Telescope (HST).
It was launched in 2003 in Russia and features
a 15 cm telescope viewing 350nm-700nm waves.
It definitely operated into 2014, and is possibly
still operating in 2018.
