Astronomical Spirograph
Posted in Astronomy at 19:15 on 7 May 2012
This picture reminded me of a spirograph, which according to Wikipedia is still going.
It’s the path the Vela pulsar traces on the gamma-ray detector of the Fermi Gamma-ray Space Telescope.
For the details of why the image is not a static one but rather traces such a complex path see Astronomy Picture of the Day for 4/5/12.
