New insight into colliding galaxies
A seemingly violent collision of two galaxies is in fact a fertile marriage that has birthed billions of new stars, and an image released recently 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.
