Humans have always wanted to learn about the Sun,

3
00:00:03.510 --> 00:00:05.680
but it is dangerous to stare at with just our eyes,

4
00:00:05.700 --> 00:00:08.610
so we built structures to help us study it.

5
00:00:08.630 --> 00:00:11.430
Aristotle had his camera obscura.

6
00:00:11.450 --> 00:00:13.010
Galileo used a telescope

7
00:00:13.030 --> 00:00:16.390
to document sun spots.

8
00:00:16.410 --> 00:00:20.810
Spectrometers came next, allowing us to study the spectrum of the Sun's light.

100 years later. George Ellery Hale

10
00:00:23.110 --> 00:00:24.480
explored the magnetic nature of the Sun

11
00:00:24.500 --> 00:00:27.060
with a spectroheliograph.

12
00:00:27.080 --> 00:00:28.549
Next, we launched Sky Lab

13
00:00:28.570 --> 00:00:31.980
and it gave us our first high-resolutions pictures of the Sun's surface.

14
00:00:32.000 --> 00:00:34.980
The YOHKOH spacecraft took x-rays of the Sun.

15
00:00:35.000 --> 00:00:39.100
Then, SOHO and Hinode sent us even more incredible images.

16
00:00:39.120 --> 00:00:44.669
TRACE delivered the closest ever pictures of the Sun and its magnetic fields.

17
00:00:44.690 --> 00:00:48.920
SDO images the Sun in many wave lengths.

18
00:00:48.940 --> 00:00:53.610
Now, with STEREO, we see the whole Sun in 3D, never missing an inch.

19
00:00:53.630 --> 00:00:57.070
Who knows what we will see next? We will just have to keep looking up...
