Researchers at Delft University of Technology (TU Delft), in close collaboration with SRON Netherlands Institute for Space Research and LongWave Photonics LLC, have achieved a breakthrough in terahertz spectroscopy—a vital technology to study galaxies, stars, and planetary formation. They created a centimeter-sized, lightweight terahertz spectrometer that could replace traditional half-meter-sized, bulky, and heavy spectrometers in future space observatories. The new device could significantly reduce costs and offer greater flexibility in launching, making these space observatories more affordable and feasible. The innovation is published in Laser & Photonics Reviews.
