Corkscrewing through the cosmos, three distant galaxies collide in a stunning new image captured by NASA's Hubble Space Telescope.

This cosmic crash is known as a triple galaxy merger, when three galaxies slowly draw each other nearer and tear each other apart with their competing gravitational forces. Mergers like these are common throughout the universe, and all large galaxies — including our own, the Milky Way — owe their size to violent mergers like this one.

As chaotic as they seem, mergers like these are more about creation than destruction. As gas from the three neighboring galaxies collides and condenses, a vast sea of material from which new stars will emerge is assembled at the center of the newly unified galaxy.

Existing stars, meanwhile, will survive the crash mostly unscathed; while the gravitational tug-of-war among the three galaxies will warp the orbital paths of many existing stars, so much space exists between those stars that relatively few of them are likely to collide, Live Science previously reported.

1. That reddish-brown area makes me think: galactic blood nt

2. "relatively few of them are likely to collide"

But if one of them is your star, that statistic does not give you much comfort.

4. The probability is much lower than that sentence might lead people to think.

3. Spectacular image.

A similar event is likely in the distant future of our own galaxy as it merges with Andromeda and possibly the Triangulum Galaxy.

This relatively brief period of rapid star formation has a downside, however, as such a merger uses up a great deal of hydrogen very quickly - a necessary ingredient in star formation - thus causing the galaxies to run out of fuel and "die" more quickly than they otherwise would have.
