M104, the Sombrero Galaxy, NGC 4594, is more than 55 millions light years away, appearing in the sky in the Constellation of Virgo. The central spheroidal cloud of stars, which has the orange appearance characteristic of an older population, is surrounded by a prominent dust ring almost 50.000 l.y. across. It is also possible to resolve some of the globular clusters, caught by this snapshot of their multi-million year orbit though the galaxy's halo.

Spiral Galaxy

Dist. 60 millions l.y.
The galaxy M100 is one of the brightest members of the Virgo Cluster of
galaxies. The galaxy is in the spring constellation Coma Berenices. M100 is spiral shaped,
like our Milky Way, and tilted nearly face-on as seen from earth. The galaxy
has two prominent arms of bright blue stars and several fainter arms. The
blue stars in the arms are young hot and massive stars which formed recently
from density perturbations caused by interactions with neighboring galaxies
which are lying just outside our image.
Despite its nearly perfect symmetric
outline, this galaxy appears slightly asymmetric, as on the southern (lower)
side of the nucleus more (or brighter) young stars have formed. Our
Deep photographs of M100 have revealed that this galaxy is actually much
larger than shown in conventional photographs. Therefore, a significant part
of the galaxy's mass may lie in the faint outer regions and escape its
discovery in conventional images.
In the inner disk of M100 has been investigated by Nasa's Ultraviolet Imaging Telescope on its Astro-1 Space Shuttle mission. Intense star
formation activity was found to take place in a ring of starburst activity along the periphery of the galaxy's innermost spiral arms.

Corona Borealis is a small and faint constellation with no important object to find but I put it in the most enjoiable ones because of the easiness to recognize and of beeing close to Bootes.
