Title: 
NGC 4565: Needle Galaxy
Explanation: 
Presenting a sleek needle-like profile [ http://nedwww.ipac.caltech.edu/cgi-bin/ nph-imgdata?objid=31109&objname=NGC%204565 ] the magnificent spiral galaxy NGC 4565 [ http://heritage.stsci.edu/public/forms/gal_desc_revised.html#4565 ] is viewed edge-on from planet Earth [ http://earthobservatory.nasa.gov/ ]. Its core of stars bulges from the centre of a thin disk of spiral arms and dust [ http://antwrp.gsfc.nasa.gov/apod/ap980326.html ]. The core appears to be cut sharply by dust lanes to dramatic effect in this composite image [ http://www.harborside.com/home/n/ngc253/4565c.htm ]. NGC 4565's obscuring dust lanes and pronounced core are typical of large majestic spiral galaxies, including our own Milky Way [ http://antwrp.gsfc.nasa.gov/apod/ap971229.html ]. To make this picture [ http://www.harborside.com/home/n/ngc253/howdone.htm ], astronomer Bill McLaughlin digitally combined a high quality black and white image with colour information from three separate exposures through red, green, and blue filters. This island universe [ ftp://crux.astr.ua.edu/web/goodies/data_resources/galaxies.text ] is about 50 million light-years away in the constellation Coma Berenices [ http://dibonsmith.com/com_con.htm ].
