Directly imaging Earth-like exoplanets is one of astronomy’s greatest challenges. Using GLINT, an interferometric instrument on the Subaru Telescope, this research cancels overwhelming starlight to reveal faint nearby planets—paving the way toward discovering another “pale blue dot” and possibly a second Earth.

This talk explains the challenge of detecting Earth-like exoplanets, the noise caused by stellar activity, and how a solar calibration instrument helps disentangle star signals from planetary ones. The speaker also studies extreme exoplanet systems, revealing surprising orbital alignments that challenge theories of giant-planet migration and highlight how much we still don’t understand.

The researcher studies how clouds on distant exoplanets affect their climates and potential for life. Working with NASA, they model how exotic materials—like iron or sapphire clouds—absorb and reflect light. They found particle shape greatly influences temperature and habitability, helping determine whether alien worlds could support liquid water and life.
