Interesting science fiction market:
The New Accelerator would like to see stories that include the following motifs/genres and styles: amazing thoughts, brilliantly realised characters and places, thrilling situations and daring ideas, noir and future noir, exploration and explorative ideas and people/places and concepts that dazzle, planets and ships and science and stars and adventure, golden dawns and flaming red sunsets, time-bending and avant-garde creations and theories, and all-round great, exciting, thrilling and wonderful stories that The New Accelerator would be happy and proud to publish.
They're looking for 2,500 to 5,000 word short SF stories, with occasional acceptances up to 10,000 words. They're only a token market, but there is a royalty split.
