Issue 28. Works on the theme of life on other planets and encounters with other creatures. What forms does life take on other planets, in other star systems? What will our meeting with other beings be like? Will it be aliens? Or, maybe, mutants living next to us, but not at all similar to us? The collection contains the best works of foreign science fiction writers, in which they try, each in their own way, to answer questions.
