English

Subject field(s)
  • Astrophysics and Cosmography
  • Space Physics
DEF

... a band of light across the night sky made up of a huge number of stars that form a large part of the galaxy that includes our sun and its planets ...

CONT

Our galaxy, the Milky Way, is typical: it has hundreds of billions of stars, enough gas and dust to make billions more stars, and at least ten times as much dark matter as all the stars and gas put together. And it's all held together by gravity.

French

Domaine(s)
  • Astrophysique et cosmographie
  • Physique spatiale
DEF

[...] bande blanchâtre floue, formée d'innombrables étoiles, constituant la trace sur la sphère céleste du disque de la galaxie à l'intérieur de laquelle se situe le Système solaire.

CONT

La Voie lactée est le nom de notre galaxie. Foyer du Système solaire, elle est de type spiral, s'étend sur environ 100 000 années-lumière et contient 100 à 400 milliards d'étoiles. À cela il faut ajouter au moins autant de planètes.

Spanish

Campo(s) temático(s)
  • Astrofísica y cosmografía

CONT

La Vía Láctea [...] es una galaxia espiral donde se encuentra el sistema solar y a su vez la Tierra. [...] De noche se ve como una borrosa banda de luz blanca alrededor de toda la esfera celeste. El fenómeno visual de la Vía Láctea se debe a estrellas y otros materiales que se hallan sobre el plano de la galaxia, como el gas interestelar.

Record 4 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)
