Mirach Merâq Fr.: Mirach Traditional name of → Beta Andromedae that may easily be confounded with → Merak (β Ursae Majoris). A variant of → Merak. |
Mirach's Ghost parhib-e Merâq Fr.: fantôme de Mirach Same as → NGC 404. |
mirage sarâb (#) Fr.: mirage An optical phenomenon caused by → refraction of light in the lowest layers of the Earth's → atmosphere especially in the → desert, over a hot pavement, or at → sea. Due to temperature variations, the air → density varies, leading to a spatial variation of the → index of refraction of → air. As a result, light from a single point takes more than one path to the observer and the → image of some distant object appears displaced from its true position; the image may appear distorted, inverted, or wavering. From Fr. mirage, from (se) mir(er) "to look at (oneself), be reflected" (from L. mirare "to wonder at, admire") + suffix -age. Sarâb "mirage," literally "water point, water origin, water head," probably from sar "origin, beginning," → head, + âb, → water. The similarity with Ar. serab (cf. Hebrew sharab "burning heat, parched ground") may be fortuitous. |
Miranda Mirândâ (#) Fr.: Miranda The eleventh of Uranus's known satellites and the innermost of Uranus' large moons. Its is about 470 km in diameter and orbits Uranus at about 130,000 km from its planet. It was discovered by Kuiper in 1948.

mirror âyene (#) Fr.: miroir A smooth, highly polished surface, for reflecting light, that may be plane or curved. The actual reflecting surface is usually a thin coating of silver or aluminum on glass. From O.Fr. mireor "a reflecting glass," earlier miradoir, from mirer "look at," from V.L. *mirare, from L. mirari "to wonder at, admire." Âyene, from Mid.Pers. êwênag "mirror," from *âdênak, cf. Khotanese âyäna- "mirror," from Proto-Iranian *ādayana-, from prefix ā- + the root of Av. dā(y)- "to see," didāti "sees" (cf. Mod.Pers. didan "to see," Mid.Pers. ditan "to see, regard, catch sight of, contemplate, experience;" O.Pers. dī- "to see;" Skt. dhī- "to perceive, think, ponder; thought, reflection, meditation," dādhye; Gk. dedorka "have seen") + suffix -ak. |
mirror blank gerde-ye âyené Fr.: disque miroir The material on which the reflecting coating is applied. It may be glass, quartz, or metal. → mirror; blank "a piece of metal ready to be drawn, pressed, or machined into a finished object," from M.E., from O.Fr. blanc (adj.) from Gmc; cf. O.E. blanca "white horse," O.H.G. blanch "bright, white." |
mirror disk gerde-ye âyené Fr.: ébauche de miroir Same as → mirror blank. |
mirror testing âzmun-e âyené (#) Fr.: test d'un miroir The observation and measurement of the flatness of a mirror surface. The process generally is done before coating so as not to damage the delicate coated surface. For coated and curved surfaces, non-contact methods are often employed, generally using interference techniques. |
Mirzam (β Canis Majoris) Merzam (#) Fr.: Mirzam The fourth brightest star in the constellation → Canis Major. It is a B1 → giant of magnitude 2.0 lying about 500 → light-years away. Mirzam is one of the brightest of the → Beta Cephei variable stars. From Ar. al-Mirzam ( |
mis- dož- (#) Fr.: més- A prefix meaning "ill, mistaken, wrong, wrongly" M.E., from O.E. mis-, cognate with M.Du. misse-, O.H.G. missa-, Ger. miss-, perhaps literally "in a changed manner," and with a root sense of "difference, change" and thus possibly from PIE root *mei- "to change;" cf. Av. miθo- "perverted," Skt. methati "changes, alternates, joins;" L. mutare "to change." Dož-, → dys-. |
misalignment dožxateš Fr.: mésalignement → Deviation of the chain of → optical components from the optimum → alignment in an instrument which leads to → loss of → light and poor → image. |
miss napidan Fr.: manquer, rater, louper 1) Fail to hit, reach, or come into contact with (something aimed at);
to fail to do something. M.E. missen, O.E. missan "fail to hit, miss (a mark); fail in what was aimed at," akin to Du. missen, Ger. missen "to miss, fail," from PIE *mei- "to change, go, move." Napidan, literally "fail attain, reach, or find," from negation suffix na-, → not, + Av. ap- "to reach, attain;" cf. Mid./Mod.Pers. (+abi-) yâftan "to obtain, to find;" Proto-Ir. *Hap/f- "to reach, attain;" PIE *H1ep- "to take, seize, grab;" cf. L. apiscor "to reach, to get" (Cheung 2007). |
missile mušak (#) Fr.: missile An object or weapon for throwing, hurling, or shooting. → ballistic missile. From Fr. missile, from L. missile "weapon that can be thrown," from missus, p.p. of mittere "to send." Mušak, literally "little mouse," or "mouse like," from a firework explosive that was likened to a mouse, from muš, → mouse, + -ak diminutive or similarity suffix. |
missing mass jerm-e gomšodé, ~ napide (#) Fr.: masse manquante The unseen mass whose gravitational influence is needed to account for the way galaxies rotate, and also to bind clusters of galaxies together. It is thought to consist, in part, of giant halos of dark matter that surround the visible portions of galaxies, and similar material that invisibly occupies the intergalactic voids. Same as → hidden mass; → dark matter. Missing, from miss "to fail to be present," from M.E. missen, O.E. missan; cf. O.Fris. missa, M.Du. missen, Ger. missen "to miss, fail;" → mass. Jerm, → mass; gomšodé "lost, missing," from gom "missing, lost" + šodé p.p. of šodan "to become" (from Mid.Pers. šudan, šaw- "to go;" Av. šiyav-, š(ii)auu- "to move, go," šiyavati "goes," šyaoθna- "activity; action; doing, working;" O.Pers. šiyav- "to go forth, set," ašiyavam "I set forth;" cf. Skt. cyu- "to move to and fro, shake about; to stir," cyávate "stirs himself, goes;" Gk. kinein "to move;" Goth. haitan "call, be called;" O.E. hatan "command, call;" PIE base *kei- "to move to and fro"); napide, p.p. of napidan, → miss. |
missing satellites problem (MSP) parâse-ye bandevârhâ-ye gomšodé, ~ ~ napide Fr.: problème des satellites manquants The observed underabundance, by one or two orders of magnitude, of → dwarf galaxies orbiting → spiral galaxies compared to their number predicted by the standard model. The → cold dark matter (CDM) model predicts that dwarf galaxies are the building blocks of large galaxies like the Milky Way and should largely outnumber them. Dwarf galaxies form first, they merge into bigger and bigger galaxies, and galaxies into groups of galaxies. The dark matter halos, however, are very dense, and dwarf halos are not destroyed in the merging, resulting in their large predicted number, in numerical simulations. Probably first dealt with in an article entitled "Where Are the Missing Galactic Satellites?" (Lypin et al. 1999, ApJ 522, 82); → missing mass; → satellite; → problem. |
mission gosilân Fr.: mission An operation designed to carry out the goals of a specific program, such as a a space flight or voyage. Mission, from L. missionem (nominative missio) "act of sending," from mittere "to send," of unknown origin.

mist nezm Fr.: brume A very thin fog consisting of an aggregate of microscopic water droplets or wet hygroscopic particles (of diameter not less than 0.5 mm), in which the visibility at the earth's surface is greater than 1 km. O.E. mist "dimness, mist," from P.Gmc. *mikhstaz (cf. M.L.G. mist, Icelandic mistur), from PIE *migh-/*meigh-; cf. Pers. miq "fog, mist;" Gk. omikhle, O.C.S. migla, Skt. megha- "cloud, mist." → nebula. Nezm "mist, fog," variants nezu, nezvâ "mist," nam "moisture, humidity;" Av. napta- "moist," nabās-câ- "cloud," nabah- "sky;" cf.
