Summary

Story summary

A research team from Tsinghua University developed a spectroscopic imaging chip named RAFAEL that could revolutionize astronomical observation.
RAFAEL achieves 0.05-nanometer spectral precision and a 10-megapixel spatial resolution, increasing observational efficiency by more than a hundredfold.
It can capture spectra from up to 5,600 stars in a single exposure.
Researchers say the chip could accelerate Milky Way mapping from millennia to under a decade and overcome the traditional resolution-efficiency trade-off.
