Fr.: relation morphologie-densité
An observationally determined relationship between the → morphological classification of galaxies and the → environments in which they are located. Specifically, the morphology-density relation indicates that early-type galaxies (→ ETG) are preferentially located in high density environments, whereas late-type galaxies (→ LTG) are preferentially found in low density environments. Hence, spiral galaxies are rare in the high densities of clusters and are common in the lower density group environments. Early-type galaxies, on the other hand, are common in clusters and are rarely found in isolation.

From O.Fr. mosaicq "mosaic work," from M.L. musaicum "mosaic work, work of the Muses," from musaicus "of the Muses," from L. Musa.
MOST Space Telescope
teleskop-e fazâyi-ye MOST
Fr.: télescope spatial MOST
A small telescope dedicated entirely to → asterolseismology. MOST is the first space telescope entirely designed and constructed by Canada. It was launched into space in 2003. The satellite weighs only 54 kg and is equipped with an ultra high precision telescope that measures only 15 centimetres in diameter. Despite its tiny size, it is ten times more sensitive than the → Hubble Space Telescope in detecting the minuscule variations in a star's luminosity caused by vibrations that shake its surface. MOST completes one orbit around the Earth every 101 minutes by passing over each of Earth's poles.
MOST, short for Microvariability and Oscillations of STars telescope.

From L. motor "mover," from movere "to move."

A general term for a relatively bright or dark feature seen in monochromatic images taken in the red Hα → Balmer line of the solar → chromosphere. Mottles constitute the fine structure of the quiet solar chromosphere and are found near bright points at → supergranulation boundaries.
Probably back formation from motley, from M.E., O.E. mot "speck," of unknown origin; maybe related to Du. mot "sawdust, grit;" Norw. mutt "speck."
Capârak noun from capâr "spotted, speckled, mottled" + -ak diminutive/similarity suffix.
Mount Wilson Observatory
nepâhešgâh-e Mount Wilson
Fr.: Observatoire du Mont Wilson
An observatory situated on a mountain 1700 m above sea level near Pasadena, California. It was built in 1904 by American astronomer George Ellery Hale as a solar-observing station for the Yerkes Observatory, but it became an independent observatory funded by the Carnegie Institution of Washington. In 1908 a 60-inch (152-cm) reflector, then the largest in the world, was added for observations of stars and galaxies. Ten years later a 100-inch (254-cm) reflecting telescope was put into service. It was the most powerful telescope in the world until the construction of the Palomar 200-inch reflector in 1948. The 100-inch telescope's most important discovery was Edwin Hubble's determination of the distance to the Andromeda Nebula in 1924. He showed that the nebula lay beyond the bounds of the Milky Way Galaxy and hence was a galaxy in its own right. Then in 1929, following the work of Vesto Slipher, Hubble and his assistant Milton Humason demonstrated that galaxies were moving away from one another. This movement is the expansion of the Universe.
