Expansion of SNR0509 Over 10 Years

Presented here is an animation of the supernova remnant SNR J0509.5-6731 expanding over time. It appears to be moving at close to 2% of the speed of light. It is around 163000 light years distant, so it has to move quite speedily for us to be able to witness its movement on a human timescale. The first frame is from 2006, and the second is from 2016. The video shows the two frames blinking back and forth to make the motion easy to see.


Note that only the narrowband (seen here as the red, smooth outline of the nebula) was available to show the nebula's expansion. The star field is essentially a static image, though the narrowband data did also capture some star movement, particularly the bright star to the left of the frame. The Chandra data was simply scaled up to match with the expansion of the shell in the Hubble data.
