Colombo is a lunar impact crater that lies on the strip of rough continental terrain between Mare Fecunditatis to the east and Mare Nectaris in the west. It is located to the south of Goclenius crater, and northwest of Cook crater. The rim of Colombo is circular, although slightly indented along the northwest where ’Colombo A’ intrudes slightly into the interior. The inner wall is asymmetrical, being much more narrow to the north and northwest and wider to the southeast. The rim is somewhat eroded, and several tiny craterlets lie along the inner wall to the southeast. The small satellite crater ’Colombo B’ lies across the south-southwestern rim. 1, record 7, English, - crater%20Colombo

Aristarchus is a prominent lunar impact crater that lies in the northwest part of the Moon's near side. It is considered the brightest of the large formations on the lunar surface, with an albedo nearly double that of most lunar features. The feature is bright enough to be visible to the naked eye, and is dazzling in a large telescope. It is also readily identified when most of the lunar surface is illuminated by earthshine. 2, record 8, English, - crater%20Aristarchus

Les déferlantes basales. Ce mécanisme (...) a d'abord été observé au cours des explosions atomiques (...) puis retrouvé au cours des éruptions de Surtsey (Islande) (...) et d'autres. Ce n'est pas un type d'éruption indépendant, mais un phénomène secondaire qui accompagne les explosions. Une partie du gaz, au lieu de s'élever verticalement, se détend horizontalement, entraînant avec elle de l'eau ou des produits solides : c'est le fameux anneau qui s'élargit à la base des "champignons atomiques". 1, record 13, French, - d%C3%A9ferlante%20basale
