Awesome

I wish someday we'd be able to find out for certain what other civilizations might exist in these other galaxies. Hopefully in our lifetime.

This intriguing trio of galaxies is sometimes
called the Draco Group, located in the northern
constellation of (you guessed it)
<A href="http://www.hawastsoc.org/deepsky/dra/index.html">Draco</A>.
From left to right are
<A href="http://antwrp.gsfc.nasa.gov/apod/ap010510.html">edge-on spiral</A> NGC 5981,
<A href="http://antwrp.gsfc.nasa.gov/apod/ap060520.html">elliptical galaxy</A> NGC 5982, and
<A href="http://antwrp.gsfc.nasa.gov/apod/ap040410.html">face-on spiral</A> NGC 5985 --
all within this single telescopic
field of view spanning a little more than
half the width of the full moon.
While the group is far too small to be a
<A href="http://www.seds.org/messier/gal_clus.html">galaxy cluster</A>
and has not been
<A href="http://www.astro.ubc.ca/people/hickson/hcg/">cataloged</A>
compact group, these galaxies all do lie roughly
100 million light-years from planet Earth.
On close examination with <A href="http://imagine.gsfc.nasa.gov/docs/
science/how_l1/spectral.html">spectrographs</A>, the bright core of the
striking face-on spiral NGC 5985 shows
prominent emission in specific wavelengths of light, prompting
astronomers to classify it as a
<A href="http://www.seds.org/~spider/spider/ScholarX/
seyferts.html">Seyfert</A>, a type of active galaxy.
Not as well known as other tight
<A href="http://antwrp.gsfc.nasa.gov/apod/ap090313.html">groupings of galaxies</A>,
the contrast in visual appearance
makes this triplet an attractive subject for
astrophotographers.</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/04B0F5F4-CEA8-4350-A390-67A95759D462/blog/" title="blog or email this clip"><img src="http://content7.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>
