Description

Exactly after 3 years: this animated gif is the continuation of: Crab Nebula (one decade time-lapse movie). Detailed informations and links to other works you can find there.

Changes for this version:

- 3 additional years (2018, 2019, 2020)

- better image quality (improved sharpness of the red filaments and improved visualization of the synchrotron radiation area)

- bigger file size (30 MBytes compared to 9 MBytes, mainly caused by more images, partly (33%) by better gif encoding quality)

- new arrangement of the frames (original version (27.12.17) 2008->2017, this version 2008->2020->2008). The movie shows the years up and down, not with a jump at the end, the movements are better visible with this arrangement.

There are two versions available:

Original: 1 frame per second, you can check the individual frames and the varying seeing.

Final: 24 frames per second, you can see the dynamical movements in the synchrotron area.

I have measured the speed of structures in the southeast oriented jet: 1.3 light years within 12 years, that means 11% of the speed of light!
