Story summary

Dr. Heidi Newberg's team at Rensselaer Polytechnic Institute has proposed a 1x20 meter rectangular mirror for future space telescopes.
This design could detect Earth-like planets more efficiently than traditional circular mirrors, offering improved angular resolution.
Simulations indicate it could identify 27 habitable-zone planets within 10 days.
The telescope would match the James Webb Space Telescope's sensitivity while exceeding its resolving power.
It is feasible with current technology and compatible with existing rockets.
