The solar wind, courtesy, the Parker Solar Probe.
Parker Solar Probe's WISPR instrument captures images of solar wind structures as they stream out from the Sun, allowing scientists to connect them with Parker's in situ measurements from its other instruments.
This video, which spans Nov. 6-10, 2018, combines views from both WISPR telescopes during Parker Solar Probe's first solar encounter. The Sun is out of frame past the combined image's left side, so the solar wind flows from left to right past the view of the telescopes. The bright structure near the center of the left edge is what's known as a streamer — a relatively dense, slow flow of solar wind coming from the Sun — originating from near the Sun's equator.
The video appears to speed up and slow down throughout the movie because of the ways data is stored at different points in Parker Solar Probe's orbit. Near perihelion, the closest approach to the Sun, the spacecraft stores more images — and more frames for a given section make the video appear to slow down. These images have been calibrated and processed to remove background noise.
Seen below is a very elegant animation of the solar wind. :)

How cool is that? :)
