Ring Galaxy

Ring Galaxy  by Joe Tucciarone, FIAAA

Collisions, side-swipes and near misses among galaxies are fairly common in the universe. The rarest of such events, is a face-on, bulls-eye impact. The impacting galaxy creates a shock wave in the thin plane of the spiral like a ripple on the surface of a pond into which a rock has been dropped. The expanding shock wave crashes through the spiral’s gas clouds, giving birth to great numbers of stars and temporarily transforming the spiral into a rare ring galaxy.


Hi Gang!  Well, after five long years, it is finally time for me to step down as the editor of the Pulsar. My job is posting me to a location where it won’t be economical for the IAAA to have me continue as the editor. So, sadly, I am passing the duties on to another. Happily, that person is Rick Sternbach, who has edited the Pulsar before. Rick brings a great enthusiasm and experience to the Pulsar and I’m sure he’ll take it to an entirely new level. Please give him the support that you’ve given me for the past five years. As this is my last issue, I decided to go out with a splash of color. I picked some of my all time favorite astronomical images to showcase - hope you like them! ;-) Best wishes to all, and we’ll see you around the listserver. Thanks!!

Jon Ramer, "Ex-"Editor

Cosmic Chasm

Cosmic Chasm 
by Dan Durda

A visually stunning piece (and my favorite work of space art - J) with a perfectly blended sky, clouds, sunset, and planet. With all the new planets being discovered in other star systems, this may not be just a fantasy scene.
