Homunculus Nebula and the Eta carinae
The relative size of the image is determined based on the three stars in the screen, and the accuracy is a few percent.
It has been 28 years since the HST image was taken, so the size has increased by more than 10%.
This change seems consistent with the expansion since the 1838 explosion.
