The Hubble Space Telescope continues to broadcast incredible images of the distant world.
The most recent is a plan showing a pair of collisional galaxies distant 230 million light-years away.
The galaxies in the shot were first discovered by William Herschel in 1784. He thought the object was a galaxy, but this was refuted as technology progressed.
Instead of a single galaxy, Hubble's latest image shows a clear picture of the fusion of two galaxies under the influence of gravity.
This is Gizmodo:
Galactic collisions are a common occurrence in galaxy life. Scientists have speculated that our neighboring galaxy, Andromeda, has had mergers in its past, for example.
Maybe the new vision of NGC 6052 will give you some hope for the future. Our own Milky Way is destined to collide with the Andromeda galaxy, according to simulations of astronomers. This collision will not happen until about four billion years ago, but it would also be an incredible sight. Unfortunately, at this point, the sun will probably be too bright for Earth to support life.
This last moment was a little depressing, so let's move on to something else that's pretty cool.
In the video below, the space becomes "sonified" in this visualization of a cluster of galaxies imaged by the Hubble Space Telescope.
The time goes from left to right and the frequency of the sound changes from bottom to top, ranging from 30 to 1000 hertz. Objects near the bottom of the image produce lower notes, while those at the very top produce higher notes.
Most visible points are galaxies with many stars. Some individual stars shine in the foreground.
Compact stars and galaxies create light and short tones, while sprawling galaxies emit longer notes that change pitch. The higher density of galaxies near the center of the image – the heart of this cluster of galaxies, known as RXC J0142.9 + 4438 – causes a swell of midtones in the video:

Keep up the good work, NASA.
