A Planet’s Rings Could Make It Shine—and Mislead Our Telescopes
Exoplanet rings may boost a planet’s reflected light enough to reveal it—but also distort estimates of its size, brightness, and atmosphere.
A Two-Telescope Trick Could Bring Far-Infrared Worlds Into Focus
A laboratory interferometer combines two apertures and a scanning spectrometer to test sharper, frequency-resolved far-infrared space imaging.
