Looks like the head of a bird, doesn't it?

<B> Explanation: </B>
Galaxies don't normally look like this.  
<A href="http://heritage.stsci.edu/public/2000nov2/ngc6745story.html">NGC 6745</A> actually shows the results of 
two galaxies that have been
<A href="http://apod.nasa.gov/apod/ap990722.html">colliding</A> for only 
hundreds of millions of years.  
Just off the 
<A href="http://hubblesite.org/newscenter/archive/releases/2000/2000/34/image/a/">above photograph</A> to the lower right is the smaller galaxy, 
moving away.  
The larger galaxy, 
<A href="http://heritage.stsci.edu/public/2000nov2/ngc6745table.html">pictured above</A>, used to be a 
<A href="http://apod.nasa.gov/apod/spiral_galaxies.html">spiral galaxy</A> 
but now is damaged and appears 
<A href="http://apod.nasa.gov/apod/ap980315.html">peculiar</A>. 
Gravity has distorted the shapes of the galaxies.  
Although it is likely that no stars in the two 
<A href="http://apod.nasa.gov/apod/ap061024.html">galaxies directly collided</A>, the gas, 
<A href="http://apod.nasa.gov/apod/ap990509.html">dust</A>, and ambient 
<A href="http://www-spof.gsfc.nasa.gov/Education/Imagnet.html">magnetic fields</A> do interact directly.
In fact, a <A href="http://www.mckinnonsc.vic.edu.au/school/ties/ties.htm">knot</A> of gas pulled off the larger galaxy 
on the lower right has now begun to form stars.  
<A href="http://en.wikipedia.org/wiki/NGC_6745">NGC 6745</A> 
spans about 80 thousand light-years across and is located about 200 million 
<A href="http://www.howstuffworks.com/question94.htm">light-years</A> away.
