From synchrotron beams to solar flares: Japan’s new X-ray optics reach orbit

🔭 A 60 mm nickel mirror, forged using synchrotron radiation techniques, has just redefined what is possible in X-ray astronomy. ⚡ Japanese researchers built and ground-tested the sharpest X-ray space telescope ever evaluated before launch — and it already captured a solar flare in progress. 🌞 If this technology can be miniaturized to fit inside a CubeSat the size of a shoebox, high-energy space observations will no longer be reserved for billion-dollar missions. 🛰️ A story about nanometer precision, sounding rockets, and the compact future of high-energy astrophysics.
