NASA
is developing ambitious future missions intended to find signs of life
on worlds around other stars. Those clues would be present in the
planet’s atmosphere: water vapor indicating an ocean, oxygen from green
plans, methane from bacteria.

To achieve this challenging goal,
we must somehow suppress massively suppress the blazing light from the
stars to see faint planets that orbit them. Two technologies being
developed to achieve this: star shades and coronagraphs. Our guests
today are experts in the technologies and the motivation for pursuing
them.
