NGC 1144

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. Our ground-based (though low-resolution) image shows the color of these galaxies and the ring of material that has formed during this galactic gala some 300 million light years away.

LRGB color production was used to create this image.

One iteration of L-R deconvolution (sharpening) algorithm using CCDsharp was applied to the luminance image.

Digital Development (DDP) via Maxim/DL was also used in order to display the very dim and very bright details of

the image simultaneously.

Luminance = 60 minutes binned 1x1

Red = 10 minutes binned 2x2

Green = 10 minutes binned 2x2

Blue = 10 minutes binned 2x2
