00:00:03.553 --> 00:00:05.470 align:middle line:84%
Today, I talked about
some of our observations

00:00:05.470 --> 00:00:07.070 align:middle line:84%
in our early release
science programs,

00:00:07.070 --> 00:00:10.030 align:middle line:84%
so, some of the first
observations done by JWST.

00:00:10.030 --> 00:00:13.660 align:middle line:84%
And what we looked at is mass
loss from a mass of evolved

00:00:13.660 --> 00:00:15.970 align:middle line:84%
stars -- so, again, these
dying types of stars.

00:00:15.970 --> 00:00:18.172 align:middle line:84%
I think that the most
compelling reason

00:00:18.172 --> 00:00:20.380 align:middle line:84%
you should care about dying
stars is the stuff you're

00:00:20.380 --> 00:00:22.090 align:middle line:90%
made of came from stars.

00:00:22.090 --> 00:00:25.210 align:middle line:84%
And if you want to understand
the origins of everything

00:00:25.210 --> 00:00:27.970 align:middle line:84%
in the universe more
complex than just hydrogen,

00:00:27.970 --> 00:00:30.400 align:middle line:84%
you have to study
these processes.

00:00:30.400 --> 00:00:33.670 align:middle line:84%
Wolf-Rayet stars, these
dying, massive stars,

00:00:33.670 --> 00:00:37.510 align:middle line:84%
are likely important sources
of dust in the interstellar

00:00:37.510 --> 00:00:38.620 align:middle line:90%
medium of the universe.

00:00:38.620 --> 00:00:43.420 align:middle line:84%
Dust is cool because dust is
critical for building planets,

00:00:43.420 --> 00:00:45.850 align:middle line:84%
for building
asteroids, for building

00:00:45.850 --> 00:00:49.660 align:middle line:84%
all of the solid parts
of our solar system.

00:00:49.660 --> 00:00:52.990 align:middle line:84%
And so, we want to understand
where all of these critical

00:00:52.990 --> 00:00:54.610 align:middle line:90%
components came from --

00:00:54.610 --> 00:00:56.860 align:middle line:84%
and there are a lot of
different possibilities.

00:00:56.860 --> 00:01:00.550 align:middle line:84%
But studying these
stellar systems with JWST

00:01:00.550 --> 00:01:05.070 align:middle line:84%
allows us to trace this dust
formation for the first time.
