Another installment of Palomar in Science Fiction will be coming before too long. In the meantime you might want to take advantage of some free SF that features a wide "range of astronomical facts and mind-blowing concepts." Just visit Diamonds in the Sky. There you can read the short stories while you are online or download them to your hand-held device and read 'em while you are on the go.
The effort was supported by the National Science Foundation. Your tax dollars at work.
