If you could speed up time and watch this galaxy evolve- the center of
NGC 3079 would bubble with hot gas not unlike the shallow lava pits
of Hawaii. A burst of star formation is creating tremendous stellar winds
and accellerating particles and gas to many thousands of light years above
(and beneath) the plane of the galaxy. These filaments of gas glow strongly
in the emission given off by excited hydrogen atoms. Click on the image
to the left to see what was barely detected in this ground-based image. The
Hubble Space Telescope image (below) obviously shows this feature with much
more clarity. Interestingly, this gas will not reach escape velocity and
will rain back down onto the plane of the galaxy and potentially trigger
more star formation!
Otherwise NGC 3079 is an colorful spiral galaxy viewed
edge-on at a distance of 50 million light years away.
This image is the second time the observer, Jeff Hapeman, has
studied this galaxy- one of his favorites. The old picture taken
with the 16in LX200 and St8E can be seen by clicking
