A color intermediate in the spectrum between yellow and blue (wavelength between 5000 and 5700 Å). The color of most grasses and leaves while growing.
Green, from O.E. grene, related to growan "to grow," from W.Gmc. *gronja- (cf. Dan. grøn, Du. groen, Ger. grün), from PIE base *gro- "to grow."
Sabz "green," from Mid.Pers. sabz "green, fresh," related to sabzi "grass."
deraxš-e sabz (#)
Fr.: rayon vert
A brilliant green color that occasionally appears on the upper limb of the Sun as it rises or sets.
Fr.: petit pois
A pea harvested and eaten while still green, soft, and unripe; a garden pea; usually in plural.
Green Pea galaxy
kahkešân-e noxod sabz
Fr.: galaxie petit pois
A member of a class of galaxies of relatively small size (→ compact galaxy) having very strong → emission lines especially the → [O III] doublet and an unusually large → equivalent width of up to 1000 Å. They were first noted because of their peculiar bright green color and small size, unresolved in → Sloan Digital Sky Survey imaging. Green Peas are similar to high-→ redshift → Lyman alpha emitting galaxies (LAEs) in many respects (small sizes, low → stellar masses, 108-10 → solar masses (Msun), low metallicities for their stellar masses, high → specific star formation rates (sSFR), and large [O III] λ5007/[O II]λ3727 ratios. Green Peas are relatively luminous and massive galaxies compared to the faint-end → dwarf starburst galaxies and LAEs (See Yang et al, 2017, arxiv/1706.02819, and references therein).
A building with transparent walls and roof, usually of glass, for the cultivation and exhibition of plants under controlled conditions (Dictionary.com).
Fr.: effet de serre
An increase in → temperature caused when incoming → solar radiation is passed but outgoing → thermal radiation is trapped by the → atmosphere. The major factors for this effect are → carbon dioxide and → water vapor. The greenhouse effect is very important on Venus and Earth but very weak on Mars. On average, about one third of the solar radiation that hits the Earth is reflected back to space. The Earth's surface becomes warm and emits → infrared radiation. The → greenhouse gases trap the infrared radiation, thus warming the atmosphere. Without the greenhouse effect the Earth's average global temperature would be -18° Celsius, rather than the present 15° Celsius. However, human activities are causing greenhouse gas levels in the atmosphere to increase.
gâzhâ-ye dârâ-ye oskar-e garmxâné
Fr.: gaz à effet de serre
Gases responsible for the greenhouse effect. These gases include: water vapor (H2O), carbon dioxide (CO2); methane (CH4); nitrous oxide (N2O); chlorofluorocarbons (CFxClx); and tropospheric ozone (O3).
Greenwich Apparent Sidereal Time (GAST)
zamân-e axtari-ye padidâr-e Greenwich
Fr.: temps sidéral apparent de Greenwich
Greenwich Mean Sidereal Time (GMST)
zamân-e axtari-ye miyângin-e Greenwich
Fr.: temps sidéral moyen de Greenwich
Fr.: méridien de Greenwich
A borough in southeast London, England, on the Thames River. It is the site of the original Royal Observatory, through which passes the prime meridian, or longitude 0°; → meridian.
Greenwich sidereal date
ruz-e axtari-ye Greenwich
Fr.: jour sidéeal de Greenwich
Greenwich sidereal day number
šomâre-ye ruz-e axtari-ye Greenwich
Fr.: nombre du jour sidéral de Greenwich
The integral part of the → Greenwich sidereal date.
