Good explanation, especially of how images were collected to make the composite shown.

Zooming into the center of the galaxy M82, one of the nearest starburst
galaxies at a distance of only 12 Million light years. The left image, taken
with the Hubble Space Telescope (HST), shows the body of the galaxy in blue and
hydrogen gas breaking out from the central starburst in red. The VLA image
(top left) clearly shows the supernova (SN 2008iz), taken in May 2008. The high-resolution VLBI images (lower right) shows an expanding shell at the scale of a few light days and proves the transient source as the result of a supernova explosion in M82</I></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.mpifr-bonn.mpg.de/public/pr/pr-m82sn-en.html">M82 is an irregular galaxy in a nearby galaxy group located 12 million 
lightyears from Earth. Despite being smaller than the Milky Way, 
it harbors a vigorous central starburst in the inner few hundred
lightyears. In this stellar factory more stars are presently born than in the 
entire Milky Way</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.mpifr-bonn.mpg.de/public/pr/pr-m82sn-en.html">it looks 
as if being torn apart in optical and infrared images as the 
result of numerous supernova explosions from massive stars (see Fig. 1, left)</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/FCB4A51F-CA23-4D1F-A1CD-6B31F1704841/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
