Because a magnetic field exerts a force on a charged particle, this solar field wave "breaks" over the comet, pulling on the ionized gas of the coma. It sweeps away the electrons, which are much lighter, and draws the heavier ions outward, into a long plasma tail (also called an ion tail) that points in the anti-sunward direction. 3, record 2, English, - anti%2Dsunward%20direction

Le satellite(FIRST) opérera depuis une orbite située au point de Lagrange L2 du système Soleil-Terre-Lune, à quelques 1. 5 millions de km de la Terre dans la direction antisolaire. Cette position permet au satellite de s’affranchir de la présence du Soleil dans son champ de vue, mais surtout de prolonger sa durée de vie. 2, record 2, French, - direction%20anti%2Dsolaire
Record number: 2, Textual support number: 2 CONT
C’est à l’approche du Soleil que les glaces se subliment dans le vide, entraînant les poussières du noyau. La comète devient alors visible. Tandis que la vapeur très légère reste confinée dans la coma, les poussières sont entraînées par la pression de radiation solaire dans la direction opposée au Soleil, formant une queue caractéristique. [...] La forme de la queue ionique s’explique par la formation d’une onde de choc. À l’intérieur de ce front l’écoulement du vent solaire est freiné par l’atmosphère de la comète et produit des turbulences qui prennent l’aspect de cordes, de nœuds et de filaments qui différencient la queue ionique de la queue de poussières. En dehors du front les ions associés à la comète sont entraînés par l’écoulement général, guidés par les lignes de force engendrées par le noyau en mouvement. Les ions s’échappent ainsi de la coma pratiquement dans la direction anti-solaire en formant une longue queue distincte. 5, record 2, French, - direction%20anti%2Dsolaire

rayons crépusculaires : Bandes d’un bleu foncé qui rayonnent à partir du Soleil et traversent la lueur pourpre pendant le crépuscule. Ce sont les ombres de nuages situés à l’horizon ou derrière l’horizon. 3, record 3, French, - rayon%20cr%C3%A9pusculaire

Si, dans la basse atmosphère, quelque chose, comme une colline ou un nuage, bloque une partie de la lumière solaire, on voit alors apparaître ce qui reste de lumière comme des rayons. Ceux-ci, intensifiés par la diffusion de la lumière dans l’air situé entre l’obstacle et l’observateur semblent diverger directement du soleil. On les appelle rayons crépusculaires ou échelle de Jacob en Angleterre. Ils peuvent apparaître autant au lever qu’au coucher du soleil, lorsque celui-ci est bas à l’horizon ou même sous l’horizon. On peut voir de tels rayons surtout quand l’atmosphère contient assez de particules de poussière ou de brume de sorte que la lumière solaire des régions sans ombre est diffusée directement vers l’observateur. En réalité, ces rayons sont parallèles, mais à cause de l’effet de parallaxe, on dirait qu’ils convergent vers le soleil. Cet effet rappelle les rails d’un chemin de fer qui semblent converger quand on les regarde au loin. La couleur de ces rayons est souvent dans les teintes de rouge ou jaune, tout simplement parce que le bleu a déjà été diffusé par les molécules d’air. 2, record 3, French, - rayon%20cr%C3%A9pusculaire
