00:05 - My name is Professor Robert Walsh,
00:32 I'm a professor of solar astrophysics
00:35 at the University of Central Lancashire,
00:37 and that's in Preston, up in the northwest of England.
00:40 And I work with NASA and the European Space Agency
00:43 to try and understand the sun, our closest star.
00:46 And what we've got behind me here
00:48 is a seven meter diameter representation of our sun.
00:53 It's real data from NASA's solar dynamics observatory.
00:58 So everything you see here really has happened on the sun.
01:00 We've taken 10 weeks in the life of the sun
01:03 and squeezed it down to 12 and a half minutes.
01:05 And every time it changes in color,
01:07 every two and a half minutes,
01:08 it's picking a different part of the light from the sun
01:11 that we see in extreme ultraviolet light.
01:14 But this is really what your star looks like
01:16 if you were to go out into space
01:18 and put these extreme ultraviolet spectra on.
