El sol de nuestro sistema es el Castor C, una estrella enana roja de sistema binario, de la que ya conocemos bastante, y otra estrella destellante, que forma pareja con la anterior (para que haya m?s variaci?n). Medea es un sat?lite, b?sicamente igual que la Tierra, de astro superjupiteriano inventado por m?. La rotaci?n cerrada hace que una cara sea calentada por Argo, el superjupiteriano, y otra cara sea calentada alternativamente por los soles Castor C. Una ?rbita inclinada genera zonas permanentes y alternantes de luz y oscuridad, como las regiones ?rtica y ant?rtica de la Tierra.
Tenebra, die Welt der Extreme, hatte sie eingefangen und lie? sie nicht mehr los. Nur der irdische Robotlehrer — eine Maschine konnte den Versuch zur Rettung der beiden Sternenkinder aus der H?lle von Tenebra unternehmen. Eine Temperatur von ?ber 180 Grad, und ein Luftdruck von 800 Atmosph?ren und eine planetare Oberfl?che, die t?glich tiefgreifenden Ver?nderungen unterworfen war, machten der Maschine nichts aus.Der Autor hat seit Jahren in den Kreisen der SFAnh?nger einen ausgezeichneten Ruf, weil er es wie kaum ein anderer versteht, die Reaktionen von Lebewesen in einer fremden Umgebung lebensecht zu schildern.
Oculto por las eternas tinieblas de su espesa atm?sfera. Tenebra era un planeta hostil, un lugar con una gravedad aplastante, con 370 grados de temperatura, con una corteza en perpetuo cambio sobre la que flotaban gigantes gotas de lluvia.A pesar de ello… all? hab?a vida, vida inteligente.Durante m?s de veinte a?os, cient?ficos terrestres estudiaron a sus habitantes desde un laboratorio en ?rbita... y hab?an encontrado un medio de entrenar y educar a un grupo de ellos.?Luego ocurri? lo inesperado! Una joven terrestre y el hijo de un poderoso e iracundo diplom?tico extraterrestre quedaron encerrados en un batiscafo que flotaba hacia la mortal superficie del planeta.?Solo los primitivos tenebritas pod?an rescatarlos!
Shrouded in eternal gloom by its own thick atmosphere, Tenebra was a hostile planet: a place of crushing gravity, 370-degree temperatures, a constantly shifting crust and giant drifting raindrops. Uncompromising—yet there was life, intelligent life on Tenebra. For more than twenty years, Earth scientists had studied the natives from an orbiting laboratory and had even found a way to train and educate a few of them.
Stranded on an alien planet, light years from home, wandering from blistering heat to searing cold, Nils Kruger was not a happy man. So when he met another being — even though it wasn’t human — things seemed to be looking up. The alien might be helpless, or it might be dangerous, but one thing was for sure — they stood a better chance for survival if they worked together. But as the two creatures overcame their mutual suspicion, as they worked together, as the language barrier was broken down, Nils came to a terrifying conclusion — this alien was more intelligent than a human. And to it, Nils was the alien…
Er ist ein Allen, und er ist ein J?ger. Sein K?rper besteht aus einem vier Pfund schweren Gallertklumpen aus einer ?u?erst feinstrukturierten Sustanz, die in jede andere Materie eindringen und mit dieser eine Symbiose eingehen kann.Seit ?ber sieben Jahren lebt der J?ger auf der Erde im K?rper des 22-j?hrigen Bob. Die ganze Zeit ?ber hat er seinen „Gastgeber“ vor Infektionen bewahrt und seine Verletzungen geheilt Trotzdem wird Bobs K?rper von Tag zu Tag schw?cher; der J?ger ist machtlos. Er wei? nur einen Ausweg: Spezialisten seiner Spezies m?ssen ...
Dhrawn era un planeta que, entre otros inconvenientes, ten?a una gravedad aplastante, cuarenta veces superior a la terrestre. Era evidentemente imposible para los terr?colas explorarlo. Por lo tanto, para llevarlo a cabo necesitar?an colocar sobre aquella superficie a alguien dotado de inteligencia e iniciativa, pero psicol?gicamente m?s apropiado que los humanos.Los seres vivientes que mejor se ajustaban a esas exigencias eran los peque?os mesklinitas, dotados de una constituci?n resistente. Aunque se encontraban en un estadio cultural inferior, los humanos pensaban que no conven?a suministrarles una elevada ayuda tecnol?gica ...
The blockbuster new novel by science fiction great Hal Clement, set in an alien-run universe created by Isaac Asimov himself. This is the story of six vastly different starfaring races coexisting under a precarious truce — an interstellar community to which the human race has recently been added.
Discover MESKLIN — Gravity: 3g at the equator, 700g at the poles!Hal Clement is a Grand Master of SF, and the one most associated with the subgenre of hard SF. From his classic stories in Astounding in the 1940s through his novels of the 1950s and on to the recent , he has made a lasting impression on SF readers, and on writers, too. For many of them, Clement’s work is the model of how to write hard SF, and this book contains the reasons why. Here are all the tales of bizarre, unforgettable Mesklin: the classic novel ...
An expedition team of scientists is exploring the planet Mercury. The constant rumblings of earthquakes and wind have shaken their ship, the Albireo. A small explorative party departs on tractors. It’s then when the volcanic reaction starts. And it looks like the end of the team unless man’s intelligence can beat the malevolent nature of a fiery planet!
Iceworld is a humorously pointed novel of clashing perspectives, which we may designate as hot versus cold. Even for readers who have not seen H. R. van Dongen's fine cover painting for the novel's first installment in Astounding, Hal Clement does not keep us long in suspense that the planet which is unaccessible because of its climate of extreme cold is our own Earth. In contrast, the dismayed observer, the alien Sallman Ken (also on the cover, not to scale!), is truly hot-blooded. Clement genially introduces mitigating circumstances:Earth, really, is not as bad as all that. Some ...
Gehuld in eeuwige duisternis door zijn eigen dikke atmosfeer Tenebra was een vijandige planeet… een plaats van het verpletteren van de zwaartekracht, 370-graden temperaturen, een voortdurend verschuivende korst en gigantische drijvende regendruppels.Weinig belovend — maar er was leven, intelligent leven op Tenebra…
El planeta Mesklin es grande y muy denso. La gravedad en su superficie var?a enormemente desde 3 g en el ecuador hasta 700 g en los polos. Los oc?anos son de metano l?quido y la nieve es amoniaco congelado. En estas condiciones de pesadilla viven los mesklinitas, quienes han desarrollado una cultura y una sociedad perfectamente acorde con las condiciones de su entorno. Barlemann, un osado marinero mesklinita, acepta emprender un viaje imposible para salvar una costosa sonda terrestre averiada en el polo del planeta. Para los mesklinitas el viaje constituye una maravillosa oportunidad de descubrir la ciencia y avanzar en el camino del conocimiento, fuerza motr?z que les gu?a a trav?s de numerosas aventuras.
La plan?te Mesklin est r?ellement singuli?re. Sa forme et sa taille sont singuli?res, la gravit? y est ?norme et irr?guli?re. Elle tourne autour d'une ?toile naine, ? une vitesse consid?rable, le jour ? sa surface ne dure que dix huit minutes.Et c'est sur cette plan?te que les hommes ont voulu faire atterrir une sonde tr?s co?teuse, au p?le m?me o? la gravit? y est de neuf cents atmosph?res. La sonde ne red?collera pas.La solution est donc de contacter le capitaine d'un ?quipage de la population locale et d'aller r?cup?rer l'appareil l? o? l'homme ne peut d?cemment survivre …
Nel futuro, la Commissione per l'Energia controller? rigidamente il mondo. Nelle profondit? dell'oceano, per?, qualcuno ha preso una strada diversa… e qualcosa di nuovo sta per accadere sulla Terra!
Well known as the author of MISSION OF GRAVITY, CYCLE OF FIRE, CLOSE TO CRITICAL and for his many other extraordinarily realistic creations of extraterrestrials, it is remarkable that Hal Clement's novelettes have never appeared in book form before. — Here are three of the best — each dealing with a different aspect of communication with creatures so alien to mankind that the first thing to do is throw speech out the window!
Two alien races lived under a single sun, someplace across the galaxy, sharing their world… sharing life itself. For they lived together in a partnership more perfect than any other known to the intelligences of the galaxy. Together, the two races became one, each deriving from the other that which made him greater than his individual self. Host and symbiote, they lived together, shared together… two bodies in one. For the one race was symbiotic, amorphous, able to enter the body of the other.Then one symbiote turned Criminal, and his race could not rest until he was tracked down. But the Criminal could hide in any living thing… and on Earth there were over two billion humans alone!HAL CLEMENT blends a masterpiece of science fiction with a story of pure detection to produce his best novel, and one of the most famous s-f novels of the past quarter-century.
