The William Herschel Telescope (WHT) just got supercharged to map 1K stars per hour, helping us investigate the origins of the Milky Way in detail. A super-fast mapping device, Weave, will place a light-transmitting tube on the precise location of each star in a patch of sky the WHT is pointed at, according to BBC. Effectively tiny telescopes in their own right, an individual tube captures light from each of the thousands of stars in a patch of sky and channels it to another instrument, which then splits it into a rainbow spectrum. Weave will be able to calculate the speed, direction, age and composition of each star observed, creating a moving map of the stars and reconstructing the formation of the Milky Way in a level of detail never seen before.

Want to imagine a busy Cairo street as a space with more greenery? DALL-E, a text-to-image program powered by San Francisco based AI lab company Open AI, creates photorealistic images drawn from a text prompt. Artist and former open-street activist Zach Katz has used DALL-E to reimagine urban areas around the world, with changes as drastic as turning a busy highway into a park or as minimal as adding sidewalks to one of his hometown roads, Bloomberg reported. The program is a much cheaper way to create renders, which could be used to visualize a way to transform urban spaces, Katz said. DALL-E, whose name is a mix between artist Salvador Dalí and the Pixar robot WALL-E, was released in January last year. Its second version, DALL-E 2, was released to journalists and artists earlier this year.
