Big Galaxy Collisions Can Stunt Star Formation
DATE: 10.07.2008
A deep new image of the Virgo cluster has revealed monumental tendrils of ionized hydrogen gas 400,000 light-years long connecting the elliptical galaxy M86 and the distributed spiral galaxy NGC4438.
Stars Stop Forming When Big Galaxies Collide
Astronomers studying new images of a nearby galaxy cluster have found evidence that high-speed collisions between large elliptical galaxies may prevent new stars from forming, according to a paper to be published in a November 2008 issue of The Astrophysical Journal Letters.
