Neith Boyce was an early 20th-century author and playwright, who worked with Eugene O'Neill, Edna St. Vincent Millay, William Carlos Williams, and E. E. Cummings through the Provincetown Players theater project. Whether or not she was named for the goddess, she was certainly an interesting and independent woman, just like our lady. (Source.)
There's a crater on Ganymede, the largest of Jupiter's moons, named after Neith. Galileo, a NASA Orbiter, took a photo of the giant ancient crater on its way by.
The "Cross of Neith" is a purple and gold Welsh battle flag, flown in the 13th century by the prince Llewellyn the Last, and it's said to symbolize a holy relic. Very pretty, just like Neith. (Yeah, we're sucking up.)
In 1672, Giovanni Cassini thought he saw a moon orbiting Venus when looking through his telescope. A number of astronomers saw this "moon," and in 1884, Jean-Charles Hozeau named it after Neith—but Hozeau actually thought it was a planet and not just a moon! Turns out they were all wrong; various tricks of light and stars can explain the strange spot that "followed Venus" in the sky. There is no moon of Venus or extra planet named Neith, though the mystery remains. Every so often, astronomers still think they see a moon or a planet out there. Even in space, Neith stays hidden behind her veil. (Source.)
