Hubble Sees Shell Elliptical Galaxy NGC 2865

Apr 13, 2015 by News Staff

Astronomers using the NASA/ESA Hubble Space Telescope have obtained a remarkable new view of a distant galaxy called NGC 2865. This image shows the shell...

Resembling looming rain clouds on a stormy day, dark lanes of dust crisscross the giant elliptical galaxy NGC 5128, also known as Centaurus A. The warped shape of NGC 5128’s disk of gas and dust is evidence for a past collision and merger with another galaxy. The resulting shockwaves cause hydrogen gas clouds to compress, triggering a firestorm of new star formation. At a distance of just over 11 million light-years, NGC 5128 contains the closest active galactic nucleus to Earth. The center is home for a supermassive black hole that ejects jets of high-speed gas into space, but neither the supermassive black hole or the jets are visible in this image.
