HEADLINE: James Webb Telescope Probes Potentially Habitable Exoplanet TRAPPIST-1e
GUEST NAME: Néstor Espinoza
SUMMARY: Dr. Néstor Espinoza's team uses the James Webb Space Telescope to study TRAPPIST-1e, 40 light-years away in the habitable zone. Using transit method analysis, they've excluded certain atmospheric compositions like cloudless Venus-like atmospheres. The team employs TRAPPIST-1b as a "stellar anchor" to correct distortions, keeping alive hopes of finding atmospheres on red dwarf planets.

| 0:37.9 | That's the James Webb with an unlimited budget. Nestor, your plans. |
| 0:44.0 | Oh, a limited budget. I will launch a suite, a fleet of James Webb's out there. |
| 0:51.1 | I think the possibilities of, I mean, if you think about it, one of the biggest |

| 1:06.9 | beyond. And if you could give me an unlimited amount of funding, I will not construct |
| 1:11.4 | just one James Webb, but several James Webb, a fleet of many, many taskups, such that we can |
| 1:17.1 | really grab all that light, all that information out of the exoplanets out there to make a survey. |
| 1:23.6 | Imagine making, not only studying like, you know, this one, Trappist one east planet, but studying |
