Summary

Story summary

NASA is developing single-photon sensing CMOS detector technology for future astrophysics missions, including the Habitable Worlds Observatory (HWO).
HWO's goal is to identify biosignatures in exoplanet atmospheres, suggesting potential life.
The SPSCMOS image sensor detects individual photons, operates with low noise, and is radiation-tolerant, essential for capturing faint signals.
The Rochester Institute of Technology is enhancing these sensors through NASA-funded initiatives.
