| [00:00:00.05] | [This is early data from the testing phase of NASA's Transiting Exoplanet Survey Satellite (TESS).] |
| [00:00:06.22] | [It captured not only a comet, but also a number of other interesting features.] |
| [00:00:12.42] | |
| [00:00:18.53] | [NEOWISE Comet C/2018 N1] |
| [00:00:24.65] | [Notice how the comet tail changes direction.] |
| [00:00:30.89] | [This change is due to the solar wind.] |
| [00:00:36.94] | [These are variable stars whose brightness changes over time.] |
| [00:00:42.95] | [All the other fixed spots are stars. Their appearance results from image processing that |
| [00:00:49.03] | makes the comet and variable stars more visible.] |
| [00:00:55.20] | |
| [00:00:57.28] | [TESS even saw a faint wisp of reflected light coming from Mars.] |
| [00:01:03.37] | |
| [00:01:09.56] | |
| [00:01:15.66] | [Last, but not least, this view is filled with asteroids. They're visible as small moving white dots.] |
| [00:01:21.79] | [Quickly running the video back and forth makes their movement more apparent.] |
