This galaxy, known as NGC 7793, has a micro-quasar called S26. The S26 appears extremely red in the upper left peripheral area of the NGC7793 in this image. The 200% enlarged image is also shown in the square box. This color is clearly different from that of many HII regions visible within this galaxy. It is believed that there is a stellar-mass black hole inside the S26.

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.
