The James Webb Space Telescope (JWST) has the potential to detect biosignatures on Earth-like planets, but practical limitations prevent it from dedicating all of its time to that resource, and launch costs are a concern.
27:20 - 33:14 (05:53)
Summary
The James Webb Space Telescope (JWST) has the potential to detect biosignatures on Earth-like planets, but practical limitations prevent it from dedicating all of its time to that resource, and launch costs are a concern. The use of cheap, lightweight mirrors could create more space-based telescopes to supplement the JWST's capabilities.

Moons should be a part of the search for Earth-like planets, as Earth-like planets around Sun-like stars are not inevitable, but moons could provide more habitable exomoons than exoplanets.
36:20 - 41:35 (05:14)
Summary
Moons should be a part of the search for Earth-like planets, as Earth-like planets around Sun-like stars are not inevitable, but moons could provide more habitable exomoons than exoplanets. While most telescope time will be spent on atmospheric retrieval, the ultimate goal is to learn everything about these planets.

Half of all sun-like stars are part of binary or trinary systems, meaning only around a third are classified as single, which could impact the search for exoplanets.
41:35 - 46:22 (04:47)
Summary
Half of all sun-like stars are part of binary or trinary systems, meaning only around a third are classified as single, which could impact the search for exoplanets. The possibility of oxygen arising from photolysis on otherwise lifeless planets also presents a challenge in distinguishing habitable exoplanets.

The barycenter, the center of mass, lives between the two celestial bodies like on a balancing arm.
55:04 - 1:03:48 (08:44)
Summary
The barycenter, the center of mass, lives between the two celestial bodies like on a balancing arm. It appeared unusual that the dip observed in the Kepler data corresponded to a Neptune-sized moon around a Jupiter-sized planet, as objects beyond half an AU and an order of tenth of Jupiter mass up to 10 Jupiter masses seem to be somewhat unusual.
