The Antennae Galaxies (NGC 4038 and NGC 4039) as captured by the Palomar 
Observatory's 200-inch (5-meter) Hale Telescope.<br>
<br>
The galaxies are located about 63 million light years away and are in the 
process of slowly merging. 
The nucleus of each galaxy is seen as the two bright, white areas of the 
image. The small white and reddish spots between them are regions of intense 
star formation that is taking place as the gas clouds within the galaxies 
collide. <br>
<br>
This image was captured by Christopher Conselice and Kevin Bundy of the&nbsp; 
California Institute of Technology in May, 2004. They used the Hale 
Telescope's Wide-field Infrared Camera (WIRC).<br>
<br>
The image was recorded in three near-infrared wavelengths: &quot;J&quot; 
centered at 1.250 microns, &quot;H&quot; at 1.635 microns, and 
&quot;Ks&quot; at 2.150. The J image was mapped to blue, H to green and 
Ks to red to make this false color image.<br>
<br>
WIRC operates at the prime focus (f/3.3) of the Hale Telescope and records a 
field of view that is 8.49 arc minutes on a side.&nbsp; The camera was 
developed jointly by Caltech and Cornell University. It features a 
2048-square Rockwell Hawaii-II NIR detector manufactured by Rockwell 
Scientific in Camarillo, California.
<p>
The research was based on observations obtained at the Hale Telescope, 
Palomar Observatory, as part of a collaborative agreement between the 
California Institute of Technology, its divisions Caltech Optical 
Observatories and the Jet Propulsion Laboratory (operated for NASA), 
and Cornell University.
