The dance of these fireflies is the dance of distant suns.
To the tune of silent drums,
flows the grace of gravity and time.
There are actually two galaxies in this image, and they are in the process of merging together. You will notice that the two brightest spots correspond to the cores of the original galaxies. They are called the Antenna Galaxies and they have been colliding with each other for at least 100 million years, triggering the formation of millions of stars in the process.
Click below to learn about why the Antennae Galaxies are named like that, about their galactic cores and the super star clusters forming stars within them.
The stars that form these interacting galaxies will most likely never engage on a collision with each other. Compared to their sizes, the space between them is enormous, so they will just go on their way between each other.
