WASHINGTON (Reuters) - A seemingly violent collision of two galaxies is in fact a fertile marriage that has birthed billions of new stars, and an image released on Tuesday gives astronomers their best view yet.

The new image of the Antennae galaxies allows astronomers working with the orbiting Hubble Space Telescope to distinguish between new stars and the star clusters that form them.

Most of these clusters, created in the collision of the two galaxies, will disperse within 10 million years but about 100 of the largest will grow into "globular clusters" -- large groups of stars found in many galaxies, including our own Milky Way.

The Antennae galaxies, 68 million light years from Earth, began to fuse 500 million years ago.

A light year is the distance light waves travel in one year -- about 6 trillion miles.

The image serves as a preview for the Milky Way's likely collision with the nearby Andromeda Galaxy, about 6 billion years from now.

17: 44. The seven heavens and the earth and all that is therein, glorify Him and there is not a thing but glorifies His Praise. But you understand not their glorification. Truly, He is Ever Forbearing, Oft-Forgiving.

39: 38. And verily, if you ask them: "Who created the heavens and the earth?" Surely, they will say: "Allah"....

57:
21. Race one with another in hastening towards Forgiveness from your Lord, and towards Paradise, the width whereof is as the width of heaven and earth, prepared for those who believe in Allah and His Messengers. That is the Grace of Allah which He bestows on whom He pleases. And Allah is the Owner of Great Bounty.


3:7...And none receive admonition except men of understanding.
