Hidden Galaxies: Unlocking the Universe’s Secrets

April Joy Jovita

Astronomers have recently uncovered evidence of “hidden galaxies,” a population of faint, dust-shrouded galaxies that could reshape our understanding of the universe. These galaxies, detected through the deepest far-infrared image ever created, may hold the key to solving mysteries about galaxy evolution and the universe’s energy budget. The Discovery of Hidden Galaxies Using data from ...

Ultra-Thin Lenses That Make Infrared Light Visible

April Joy Jovita

Physicists at ETH Zurich have developed an ultra-thin lens capable of converting infrared light into visible wavelengths. This breakthrough, achieved using lithium niobate metasurfaces, could revolutionize imaging technology by enabling compact, high-performance optical devices. How Metalenses Work Traditional lenses rely on curved glass to bend light toward a focal point, but metalenses use nanoscale structures ...
