The scaling of next-generation ground- and space-based telescopes presents a critical challenge, as traditional diffraction-grating spectrographs scale in volume and mass roughly with the square of the telescope diameter, leading to prohibitive costs and stability issues. Photonic technology offers a promising solution...

Astrophotonics is an emerging field that exploits photonic technologies to enable the miniaturization and integration of astronomical instrumentation. However, the fiber-coupling issue is arguably the most heated debate to determine whether photonics devices could become a practical solution for the development of next...
The Earth 2.0 (ET) mission, led by China, aims to detect over 50,000 exoplanets, including potentially habitable Earth-like planets around Sun-like stars (”Earth 2.0s”), cold low-mass planets, and free-floating planets. The mission will employ six 28-cm telescopes to conduct ultra-high-precision photometric monitoring...
