Evolution of the pulsar wind nebula in the constellation Vela

Temporal evolution of the Vela pulsar wind nebula as observed in the spectral energy range 0.5-8 keV.

 

 

Temporal evolution of the Vela pulsar wind nebula as observed in the spectral energy range 0.5-8 keV.

 

 

The distance to the nebula is about 1,000 light years. 11 images of the Vela pulsar wind nebula are based on the data obtained between July 2009 and September 2010, by the Chandra orbital X-ray observatory. The time interval between the images is approximately 10 days, except for the 3rd and 4th images, where the interval is 11 months.

 

The nebula contains two arches, internal and external, as well as an extended outer jet (top right) and a small counter-jet. The variability of the outer jet is especially noticeable, but other parts of the nebula also change over time, as can be seen in the video.

 

The spatial variability of the counter-jet is seen most clearly in the inner part of the nebula. The typical speed of matter in the nebula is about one half of the speed of light.
