Record 1 2015-03-11

English

Subject field(s)
  • Meteorology
  • Astronomy
DEF

Faint spot of light, round or elongated, in the night sky at the antisolar point [i.e., 180° from the sun], linking the east and west zodiacal lights.

CONT

gegenschein or counterglow ... is caused by reflection of sunlight by small dust particles that lie in the plane of the solar system. It is possible that these particles are part of a tail of the earth, extending away from the sun like the tail of a comet. The gegenschein is one of several skyglows that also include the zodiacal light and the zodiacal band.

CONT

[The] counterglow ... very difficult to observe [is] caused by very thinly spread interplanetary material.

OBS

gegenschein: often capitalized.

OBS

counterglow: usually known by its German name, the Gegenschein.

Key term(s)
  • counter-glow

French

Domaine(s)
  • Météorologie
  • Astronomie
DEF

Faible tache lumineuse, ronde ou allongée, apparaissant dans le ciel nocturne au point antisolaire [i.e., à 180 degrés du Soleil] et réunissant les lumières zodiacales ouest et est.

CONT

La lumière zodiacale et le gegenschein sont causés par la poussière interplanétaire.

OBS

Gegenschein : terme allemand généralement employé pour désigner la lumière antisolaire.

Key term(s)
  • lumière anti-solaire
  • lueur anti-solaire

Spanish

Campo(s) temático(s)
  • Meteorología
  • Astronomía
DEF

Débil mancha luminosa, redonda o alargada, que se observa en el cielo nocturno en el punto antisolar, uniendo las luces zodiacales del este y del oeste.

OBS

Gegenschein: término alemán generalmente utilizado para designar la luz antisolar.

Record 2 2004-11-16

English

Subject field(s)
  • Geophysics
  • Astrochemistry and Cosmochemistry
  • Atmospheric Physics
DEF

A cone of light extending upward from the horizon in the direction of the ecliptic.

CONT

The material that leaves comets may in part account for the myriads of tiny particles that pervade the solar system. These particles become visible just after sunset or before sunrise as a faint glow extending up into the sky from a point on the horizon just above the sun. The faint glow follows the ecliptic and is called the "zodiacal light", for it is seen along the zodiac (the band of twelve constellations along the ecliptic).

OBS

zodiacal light. It is seen from tropical latitudes for a few hours after sunset or before sunrise.

French

Domaine(s)
  • Géophysique
  • Astrochimie et cosmochimie
  • Physique de l'atmosphère
DEF

Lueur faible et diffuse, concentrée autour du Soleil, dans le plan de l’écliptique, observable en début et fin de nuit; elle est due à la diffusion de la lumière solaire par la matière interplanétaire.

CONT

lumière zodiacale :Lumière blanche ou jaunâtre [...] On l'observe lorsque le fond du ciel est suffisamment noir et l'atmosphère suffisamment limpide.

Spanish

Campo(s) temático(s)
  • Geofísica
  • Astroquímica y cosmoquímica
  • Física de la atmósfera
DEF

Franja luminosa más brillante que la vía Láctea, que puede verse en el cielo por occidente tras el ocaso, o por oriente antes del alba.

Record 3 2003-07-21

English

Subject field(s)
  • Astrophysics and Cosmography
CONT

This is an issue related to all observatories, how sky background degrades ability to detect faint stars for long CCD exposures.

CONT

Since the brightness in the image of the star is from both star light and background sky light, this will include subtracting the sky light in order to get the brightness of the star alone.

French

Domaine(s)
  • Astrophysique et cosmographie
DEF

Ensemble des rayonnements émis par des sources non résolues et non détectées individuellement par l’instrument astronomique utilisé.

OBS

Un fond de ciel est caractéristique du domaine de fréquences de l’instrument utilisé.

OBS

Pour un observateur terrestre, le fond de ciel comprend, en particulier, la lumière zodiacale, les émissions atmosphériques telles que la lumière du ciel, les étoiles et autres astres non résolus et, de jour, la lumière solaire diffusée par l'atmosphère.

English

Subject field(s)
  • Facilities and Instruments (Astronomy)
OBS

Astrophotometer was created by analogy with the term astrophotograph.

OBS

photometer: an instrument used in measuring the intensity of light, esp. in determining its relative intensity from different sources.

French

Domaine(s)
  • Installations et instruments (Astronomie)
DEF

Télescope électronique qui permet de déterminer notamment les traces de poussière de l'environnement lunaire et la luminescence de la lumière zodiacale.
