High-speed galaxy collision might stop new star formations
While studying new images of a galaxy cluster located close to Earth, Yale astronomers have discovered that high-speed collisions between large elliptical galaxies might inhibit the formation of new stars. The data from the study provide some of the most substantial evidence discovered so far for high-speed collisions between large galaxies. It also offers scientists an explanation other than black holes for what prevents star formation in big galaxies.
