|If this image was a Far Side cartoon, the caption would read " When Galaxies Collide." Observational evidence seems to indicate that the elliptical galaxy to the upper right of NGC 1144 (center) recently punched right through the heart of what used to be a regular spiral galaxy. NGC 1144 has now developed a distorted ring-like structure that has spectacular star formation and high velocity gas (600-1,000 km/s). In fact astronomers have theorized that either the nucleus of NGC 1144 is releasing a jet of gas in our direction- or the nucleus itself is being ejected towards us. The HST image to the right shows the spiral nature of NGC 1144. Our ground-based (though low-resolution) shows the color of these galaxies and the ring of material that has formed during this galactic gala some 300 million light years away.||
