"The rim of the large blue galaxy at the right is an immense ring-like structure 150,000 light years in diameter composed of newly formed, extremely bright, massive stars. AM 0644-741 is known as a ring galaxy and was caused by an immense galaxy collision. When galaxies collide, they pass through each other and their individual stars rarely come into contact. The large galaxy's ring-like shape is the result of the gravitational disruption caused by a small intruder galaxy passing through it. When this happens, interstellar gas and dust become compressed, causing a wave of star formation to move out from the impact point like a ripple across the surface of a pond.
Other galaxies in the field of view are background galaxies, not interacting with AM 0644-741. Foreground spiky stars are within our own Milky Way. But the smaller intruder galaxy is caught above and right, near the top of the frame taken by the Hubble Space Telescope. Ring galaxy AM 0644-741 lies about 300 million light years away toward the southern constellation Volans."

"The eternal silence of infinite spaces frightens me. Why now rather than then? Who has put me here? By whose order and direction have this place and time have been ascribed to me? We travel in a vast sphere, always drifting in the uncertain, pulled from one side to another. Whenever we find a fixed point to attach and to fasten ourselves, it shifts and leaves us; and if we follow it, it eludes our grasp, slips past us, and vanishes for ever. Nothing stays for us. This is our natural condition, most contrary to our inclination; we burn with desires to find solid ground and an ultimate and solid foundation for building a tower reaching to the Infinite. But always these bases crack, and the earth obstinately opens up into abysses. We are infinitely removed from comprehending the extremes, since the end of things and their beginning are hopelessly hidden from us in an encapsulated secret; we are equally incapable of seeing the Nothing from which we were made, and the Infinite in which we are swallowed up."
- Blaise Pascal
