A composite image of the optical light (green and yellow)
and cold atomic hydrogen gas (blue) in the
"Ring Galaxy"
Arp 143 (a.k.a. NGC 2444/5).
The atomic hydrogen observations, taken with the VLA
in its C and D-array configurations, shows a suprising gaseous
tidal tails reaching far to the north of this galaxy,
to a total distance of 175 kpc or 570,000 light years in
length (for Ho=75 km/s/Mpc). There was no hint of this tidal
tail in previous optical images.
Deeper optical imaging may show a hint of starlight associated
with the tail, but it is mostly a gaseous structure.
Notice gas also associated with
the classical grand-design spiral galaxy to the right Investigator(s): P. Appleton, F. Ghigo, J. van Gorkom, J. Schombert & C. Struck-Marcell. Image by J. Hibbard This image is available in the following downloadable versions: If you would like to obtain a higher resolution version of this image,
