WEBVTT FILE 1 00:00:00.050 --> 00:00:06.220 [This is early data from the testing phase of NASA's Transiting Exoplanet Survey Satellite (TESS).] 2 00:00:06.220 --> 00:00:12.420 [It captured not only a comet, but also a number of other interesting features.] 3 00:00:12.420 --> 00:00:18.530 4 00:00:18.530 --> 00:00:24.650 [NEOWISE Comet C/2018 N1] 5 00:00:24.650 --> 00:00:30.890 [Notice how the comet tail changes direction.] 6 00:00:30.890 --> 00:00:36.940 [This change is due to the solar wind.] 7 00:00:36.940 --> 00:00:42.950 [These are variable stars whose brightness changes over time.] 8 00:00:42.950 --> 00:00:49.030 [All the other fixed spots are stars. Their appearance results from image processing that 9 00:00:49.030 --> 00:00:55.200 makes the comet and variable stars more visible.] 10 00:00:55.200 --> 00:00:57.280 11 00:00:57.280 --> 00:01:03.370 [TESS even saw a faint wisp of reflected light coming from Mars.] 12 00:01:03.370 --> 00:01:09.560 13 00:01:09.560 --> 00:01:15.660 14 00:01:15.660 --> 00:01:21.790 [Last, but not least, this view is filled with asteroids. They're visible as small moving white dots.] 15 00:01:21.790 --> 00:01:27.990 [Quickly running the video back and forth makes their movement more apparent.] 16 00:01:27.990 --> 00:01:36.296
