Molecular clouds are so important because they are the raw material of stars and planets. A dark nebula (or dark cloud) is a very dense part of a bigger molecular cloud; the light extinction is caused by the high density and the presence of interstellar dust in these clouds. 2, record 1, English, - dark%20nebula

The green channel is the cleanest on digital cameras and therefore the sensors deliver less noise. Because of this, green screens are by far [more] popular [than blue screens]. Extremely versatile, green screens work great for indoor, outdoor or studio shoots. And, because of their brightness, you'll be able to get away with using fewer studio lights (thus saving time and money when shooting.) 4, record 2, English, - green%20screen
Record number: 2, Textual support number: 1 OBS
With modern digital cameras, the green color is processed the cleanest with the most luminance. The result is that you'll often be able to pull a clean key with the least amount of noise, and often, without a complicated lighting setup. Conversely, because of green's brightness, it can also lead to more "spill," meaning the green color may reflect and bleed over on your on-screen talent. ... To combat this, ensure that there is sufficient distance between the talent and the green screen background. Green is also an ideal choice if you're compositing in a "daytime" background. Any leftover green can blend better into daytime footage, while it's more challenging to blend green against a darker (or nighttime) background. 5, record 2, English, - green%20screen

Le vert est utilisé surtout en vidéo car les capteurs CCD [dispositif à couplage de charge] des caméras vidéo sont plus sensibles au vert [en] raison de la matrice de Bayer qui alloue plus de pixels pour le canal vert. En plus, grâce à cette sensibilité accrue des capteurs pour la couleur verte, les fonds de cette couleur nécessitent aussi moins de lumière.

«lumière d’ambiance» : Lamouret (Cf. LACIN, 1967, p. 132) utilise aussi le terme "Lumière ambiante" au sens de lumière naturelle environnante, par opposition à la lumière d’appoint qui est une source artificielle d’éclairage. Il est à noter que les sources unilingues consultées ne font pas la distinction de cause à effet entre les termes LUMIÈRE ("light") et ÉCLAIRAGE ("lighting"), et emploient les deux notions de façon interchangeable. 8, record 3, French, - ambiance

A solar halo is a luminous ring that is sometimes seen surrounding the Sun. Some parts of the halo are very bright, others are not very bright. Sometimes, only a part of the ring is visible. Within the solar halo, on opposite sides of the Sun, there can be two very bright spots called "sun dogs" or "mock suns." The halo is produced as sunlight is reflected and refracted through tiny, flat ice crystals in the atmosphere. Sun dogs and halos always are at an angle of 22° away from the Sun, due to the hexagonal structure of the ice crystals. The diameter of the halo is about an eighth of the sky. 1, record 10, English, - solar%20halo

Les différentes formes de cristaux pointant dans différentes directions sont responsables des différentes formes de halos. Les halos solaires sont assez fréquents, mais peu de gens les observent car le ciel est généralement trop lumineux quand ils se forment. Ils présentent habituellement en leur partie interne, une coloration rouge pâle, se dégradant souvent en jaune, vert, blanc et, en leur partie externe, un bord bleu ou violet.

Les télescopes à miroir liquide : Le procédé repose sur un principe simple.

Leur inconvénient majeur est, bien sûr, qu'ils ne peuvent «pointer» que la verticale où ils sont installés. [...] Les détecteurs CCD en mode «drift-scan» permettent de «suivre» le déplacement apparent des sources et d’intégrer leur lumière pendant un temps de pose significatif. Ces poses, cumulées sur un certain nombre de nuits, permettent l'observation de «bandes» de ciel avec une profondeur en magnitude apparente tout à fait comparable à celle des observations pointées en imagerie sur un télescope moderne. 4, record 13, French, - t%C3%A9lescope%20%C3%A0%20miroir%20liquide

Lorsque vous observez le passage de la lumière blanche à travers un prisme, vous pouvez remarquer qu'elle se décompose en différentes couleurs. La lumière blanche est en réalité un mélange de toutes les couleurs, celles de l'arc en ciel. Or une lentille simple se comporte localement comme un prisme et a donc tendance à séparer les couleurs. L'image n’ est alors nette que pour le bleu, que pour le vert ou que pour le rouge. C'est l'aberration chromatique. Afin de palier ce problème, qui rend donc les images floues, on adjoint plusieurs lentilles de nature différentes permettant ainsi de focaliser la plupart des couleurs en un même point. Si l'objectif possède deux lentilles, on parle de système achromatique et s’il en possède trois, de système apochromatique. 2, record 15, French, - aberration%20chromatique

MIDI(MID-Infrared Interferometric Instrument) est une instrumentation destinée à exploiter prochainement le mode interférométrique du Very Large Telescope(VLTI) que l'ESO construit au Chili.. Il sera en mesure de combiner des faisceaux lumineux dans la bande de 7 à 13 mm de longueur d’onde. [...] caractéristiques de MIDI :-MIDI doit être refroidi à une température cryogénique, 4 K pour le détecteur et 40 K pour les optiques.-Deux faisceaux sont combinés de façon coaxiale, la détection du signal est réalisée dans le plan d’image.-À partir de la boîte de recombinaison, les deux faisceaux qui interfèrent partagent le même axe optique.-Afin de déterminer la valeur du fond thermique, l'évaluation du flux total est réalisée en sautant alternativement entre la mesure sur l'objet d’intérêt et sur une région vide du ciel(mode chopping).-Un ensemble de prisme et de grism(prisme + réseau de diffraction), placés sur le chemin optique après la recombinaison des faisceaux, fournit une résolution spectrale moyenne mais dans le même temps sert à éviter la saturation du détecteur.-Une partie de la lumière entrante est extraite avant la recombinaison et acheminée sur le faisceau photométrique.-Le faisceau photométrique et le signal interférométrique sont envoyés sur le même détecteur. 2, record 22, French, - signal%20interf%C3%A9rom%C3%A9trique

The veneration of trees was a prominent theme in the Paganism of ancient and classical times. Many rituals took place in sacred groves and much of their symbolism involved the cosmic tree; its branches supported the heavens, its roots penetrated the underworld, and its trunk was the centre of the earth. The mysteries of the forest can be incorporated into modern Paganism. This gives a new perspective on the cycle of seasonal festivals. 1, record 23, English, - sacred%20grove

Aussi le jardin persan est-il comme un bois sacré où viennent s’unir les éléments fondamentaux de l'univers. Les bassins et les canaux y sont dépourvus de margelle. L'architecte veille soigneusement à ce que la surface de l'eau affleure avec exactitude l'allée qu'elle borde. Ainsi, le ciel et la terre et les plantes confondent leurs reflets, et le regard passe de l'un à l'autre sans transition aucune : univers de rêve ou de méditation, confusion des formes, où la lumière seule accorde à son gré ou retire la réalité. 1, record 23, French, - bois%20sacr%C3%A9

Uplighting is one of the most striking of all lighting effects, because the light direction is counter to the normal daylight experience. It is most often used to accent plants or other landscape features. This lends a glowing silhouette effect to the object since there is a high contrast between outline and horizontal surfaces. 2, record 24, English, - up%2Dlighting
